Description

[0001]MACHINE DIRECTION ORIENTED FILM TECHNICAL FIELD The present disclosure is direct to machine direction oriented (MDO) films comprising a first skin layer, at least one core layer, and a second skin layer, where at least the first skin layer and the at least one core layer comprise a nucleated polyethylene blend. BACKGROUND ART U.S. Pat. No.10,730,221 teaches a machine direction oriented, multilayer film, in which a nucleated high density polyethylene material is used in a core layer. The oriented films have good barrier properties such as low water vapor transmission rates and low oxygen transition rates. In the Examples, 1200 ppm of HYPERFORM®HPN-20E, a dicarboxylic acid salt (available from Milliken) was used to nucleate a HDPE core layer. U.S. Pat. Appl. Pub. No.2020 / 0114627 discloses a machine direction oriented, polyethylene film, in which a nucleated high density polyethylene is used specifically in a skin layer. Among the nucleating agents contemplated for use was HYPERFORM HPN- 20E. The nucleating agent is used in an amount of from about 0.1 to about 7 % by weight of the skin layer that contains it, and the machine direction oriented multilayer films have improved stiffness and optical properties relative to unoriented films. There remains a need for new multilayer film structures which have a good balance of physical and optical properties.

DESCRIPTION OF EMBODIMENTS As used herein, the term “monomer” refers to a small molecule that may chemically react and become chemically bonded with itself or other monomers to form a polymer. As used herein, the term “^-olefin” or “alpha-olefin” is used to describe a monomer having a linear hydrocarbon chain containing from 3 to 20 carbon atoms having a double bond at one end of the chain; an equivalent term is “linear ^-olefin”. An alpha-olefin may also be referred to as a comonomer. As used herein, the terms “polyethylene”, “polyethylene composition” or “ethylene polymer”, refers to macromolecules produced from ethylene monomers and optionally one or more additional monomers; regardless of the specific catalyst or specific process used to make the ethylene polymer. In the polyethylene art, the one or more additional monomers are often called “comonomer(s)” and typically include ^-olefins. The term “homopolymer” generally refers to a polymer that contains only one type of monomer. The term “copolymer” refers to a polymer that contains two or more types of monomer. Common polyethylene types include high density polyethylene (HDPE); medium density polyethylene (MDPE); linear low density polyethylene (LLDPE); and very low density polyethylene (VLPDE) or ultralow density polyethylene (ULPDE) which are also known as plastomers and elastomers. The term polyethylene also includes polyethylene terpolymers which may include two or more comonomers in addition to ethylene. The term polyethylene also includes combination of, or blends of, the polyethylene types described above. The term “heterogeneously branched polyethylene” refers to a subset of polymers in the ethylene polymer group that are produced using a heterogeneous catalyst system; non- limiting examples of which include Ziegler-Natta or chromium catalysts, both of which are well known in the art. The term “homogeneously branched polyethylene” refers to a subset of polymers in the ethylene polymer group that are produced using single-site catalysts; non-limiting examples of which include metallocene catalysts, phosphinimine catalysts, and constrained geometry catalysts all of which are well known in the art. Typically, homogeneously branched polyethylenes have narrow molecular weight distributions, for example gel permeation chromatography (GPC) Mw / Mnvalues of less than about 2.8, especially less than about 2.3, although exceptions may arise; Mw and Mn refer to weight and number average molecular weights, respectively. In contrast, the Mw / Mnof heterogeneously branched ethylene polymers are typically greater than the Mw / Mn of homogeneous polyethylene. In general, homogeneously branched ethylene polymers also have a narrow composition distribution, i.e. each macromolecule within the molecular weight distribution has a similar comonomer content. Frequently, the composition distribution breadth index “CDBI” is used to quantify how the comonomer is distributed within an ethylene polymer, as well as to differentiate ethylene polymers produced with different catalysts or processes. The “CDBI50” is defined as the percent of ethylene polymer whose composition is within 50 weight percent (wt. %) of the median comonomer composition; this definition is consistent with that described in WO 93 / 03093 assigned to Exxon Chemical Patents Inc. The CDBI50of an ethylene copolymer can be calculated from TREF curves (Temperature Rising Elution Fractionation); the TREF method is described in Wild, et al., J. Polym. Sci., Part B, Polym. Phys., Vol.20 (3), pages 441-455. Typically the CDBI50 of homogeneously branched ethylene polymers are greater than about 70% or greater than about 75%. In contrast, the CDBI50of ^-olefin containing heterogeneously branched ethylene polymers are generally lower than the CDBI50 of homogeneous ethylene polymers. For example, the CDBI50 of a heterogeneously branched ethylene polymer may be less than about 75%, or less than about 70%. In the present disclosure, the terms “ethylene homopolymer” or “polyethylene homopolymer”, is used to refer to a polymer which is the product of a polymerization process, in which only ethylene was deliberately added or deliberately present as a polymerizable monomer. In the present disclosure, the terms “ethylene copolymer” or “polyethylene copolymer”, it is meant that the polymer being referred to is the product of a polymerization process, in which ethylene and one or more than one ^-olefin were deliberately added or were deliberately present as a polymerizable monomer. As used herein the term “unsubstituted” means that hydrogen radicals are bonded to the molecular group that follows the term unsubstituted. The term “substituted” means that the group following this term possesses one or more moieties (non-hydrogen radicals) that have replaced one or more hydrogen radicals in any position within the group. The term “film” is used herein to mean a film having one or more layers which is formed by the extrusion of a polymer through one or more die openings. The term “film structure” is used to connote that a film has more than one layer (i.e. a film structure may have at least two layers, at least three layers, at least four layers, at least five layers, etc.). In the present disclosure the terms “machine direction oriented polyethylene film”, “MDO PE film”, “machine direction oriented polyethylene films structure”, or “MDO PE film structure” generally describes a machine direction oriented film or film structure in which polyethylene is the main constituent polymer (i.e. polyethylene is present in higher weight percent than other, non-polyethylene polymers, based on the total weight of polymer present in the film or film structure). The phrase “all polyethylene” as used herein, when used to describe a film or a film structure, means that the film or film structure will comprise at least 90 percent by weight of a polyethylene (as opposed to non-polyethylene based polymeric materials or compositions), based on the total weight of polymer present in the film or film structure. A “skin” layer is an exterior layer of a multilayer film structure (e.g. a layer having an external surface exposed to the environment, or when present in a packaging application, a skin layer may be a layer having an external surface exposed to an enclosed environment). A “core” layer is an interior layer of a multilayer film structure (e.g. a layer adjacent to an inner surface of a skin layer, or adjacent to another interior layer or adjacent to another core layer). A multilayer film structure may have one or more core layers which may also be deemed interior or intermediate layers. MDO Film Structure In an embodiment, the machine direction oriented (MDO) films of the present disclosure are prepared from a multilayer film which comprises at least three layers, and in which a first skin layer and at least one core layer comprise a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In an embodiment, the machine direction oriented (MDO) films of the present disclosure are prepared from a multilayer film which comprises at least three layers, and in which a first skin layer, at least one core layer and a second skin layer comprise a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In an embodiment, the machine direction oriented (MDO) films of the present disclosure are prepared from a multilayer film which comprises at least five layers, and in which a first skin layer and at least one core (or intermediate) layer comprise a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In an embodiment, the machine direction oriented (MDO) films of the present disclosure are prepared from a multilayer film which comprises at least five layers, and in which a first skin layer, at least one core (or intermediate) layer and a second skin layer, each comprise a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In an embodiment, the machine direction oriented (MDO) films of the present disclosure are prepared from a multilayer film which comprises at least five layers, and in which a first skin layer, three core (or intermediate) layers and a second skin layer, each comprise a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In embodiments of the disclosure, other layers may be present in the machine direction oriented films of the present disclosure, and may be made from the polyethylene blend described herein or they may be made from one or more polyethylene selected from the group consisting of VLDPE, MDPE, and LLDPE. In embodiments of the disclosure, three layers of a MDO multilayer film structure are a first a skin layer, a core layer and a second skin layer, wherein each of the first skin layer, the core layer, and the second skin layer are directly adjacent to one another, and wherein each comprises a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In embodiments of the disclosure, five layers of a MDO multilayer film structure are a first a skin layer, three core layers and a second skin layer, wherein each of the first skin layer, the core layers, and the second skin layer are sequentially, directly adjacent to one another, and wherein each comprises a polyethylene blend comprising a nucleating agent or a mixture of nucleating agents. In embodiment of the disclosure, the polyethylene blend further comprises fewer than 750 ppm of a nucleated agent of a mixture of nucleating agents (based on the weight of the polyethylene blend). In further embodiments, the polyethylene blend further comprises from 50 to 500 ppm, or from 50 to 250 ppm, or from 50 to 200 ppm, or from 50 to 160 ppm, or from 60 to 160 ppm, or from 50 to 150 ppm of a nucleated agent of a mixture of nucleating agents (based on the weight of the polyethylene blend). In an embodiment, the MDO film structure will be an “all-polyethylene” film structure in which polyethylene polymers make up at least 90 percent by weight of the polymeric material used in the MDO film structure. In an embodiment, the MDO film structure will be an “all-polyethylene” film structure in which polyethylene polymers make up at least 95 percent by weight of the polymeric material used in the MDO film structure. In an embodiment, the MDO film structure will be an “all-polyethylene” film structure in which polyethylene polymers make up at least 99 percent by weight of the polymeric material used in the MDO film structure. In an embodiment, the MDO film structure will be an “all-polyethylene” film structure in which polyethylene polymers make up about 100 percent by weight of the polymeric material used in the MDO film structure. The polyethylene blend, as well as the ethylene copolymer composition and the ethylene homopolymer composition are all described in further detail below. Machine Direction Orientation (MDO) Machine Direction Orientation (MDO) of polymer films, including those made from polyethylene is well known to those skilled in the art and the process is widely described in the literature. MDO takes place after a film has been formed. The “precursor” film (i.e., the film as it exists prior to the MDO process) may be formed in any conventional film molding process. Two film forming processes that are in wide commercial use (and are suitable for preparing the precursor film) are the blown film process and the cast film process. The precursor film is stretched (or, alternatively stated, strained) in the MDO process. The stretching is predominantly in one direction, which is the “machine direction” from the initial film molding process (i.e., as opposed to the transverse direction). The thickness of the film decreases with stretching. A precursor film that has an initial thickness of 10 mils and a final thickness after stretching of 1 mil is described as having a “stretch ratio” or “draw down” ratio or “draw ratio” of 1:10. In general, the precursor film may be heated during the MDO process. During the stretching process, the temperature is typically higher than the glass transition temperature of the polyethylene and lower than the melting temperature and more specifically, in embodiments of the disclosure, may be in the range of from about 70°C to about 120°C. Heating rollers are generally used to provide this heat. A typical MDO process utilizes a series of rollers that operate at different speeds to apply a stretching force on a film. In addition, two or more rollers may cooperate together to apply a comparison force (or “nip”) on the film. The stretched film is generally overheated (i.e., maintained at an elevated temperature), and in embodiments of the disclosure at from about 90°C to about 125°C, in order to allow the stretched film to relax. An exemplary process for making a machine-direction oriented polymeric film is described in U.S. Pat. Appl. No.2020 / 0114627. A precursor film or film structure (i.e., a film prior to MDO) may be produced by either a cast film process or a blown film process. In an embodiment, a precursor substrate film to be stretched via MDO to form a machine direction-oriented film is formed using a blown film process. Blown film processes are well known to persons skilled in the art. Methods for blown film extrusion are described in The Wiley Encyclopedia of Packaging Technology, pp.233-238 (Aaron L. Brody et al. eds., 2nd Ed.1997), which is incorporated herein by reference. In an embodiment, a precursor substrate film to be stretched via MDO to form a machine-direction oriented film is formed using a cast film process. Cast film structures are well known to persons skilled in the art. For example, the cast film process involves the extrusion of molten polymers through an extrusion die to form a thin film, which is then pinned to the surface of a chill roll. Methods for film extrusion are also described in U.S. Pat. No.6,265,055, and in references disclosed therein, all of which are incorporated herein by reference. In an embodiment, the precursor substrate film (e.g. produced by a blown or a cast film extrusion process) may then be stretched via machine direction (MD) orientation by a process analogous to that shown in simplified schematic form in FIG.2 of U.S. Pat. Appl. No.2020 / 0114627 in order to form a machine direction-oriented polymeric film. Alternatively, in another embodiment, the precursor substrate film (e.g. produced by a blown or a cast film extrusion process) may then be stretched via machine direction (MD) orientation by a process analogous to that shown in FIG.6 of U.S. Pat. Appl. No. 2020 / 0114627 in order to form a machine direction-oriented polymeric film. For example, a precursor film prepared via an extrusion process enters a preheat section prior to being stretched. In some embodiments, the preheating may be achieved by running the film over 2 or 3 heated rolls. The purpose of the preheating step is to uniformly raise the temperature of the film to orientation temperature. In embodiments, the roll and film temperature for polyethylene films is between about 170°F and about 260°F, in other embodiments between about 200°F and about 260°F. In embodiments, the preheating rolls are run at the higher end of this temperature range to improve optical properties such as gloss and haze. In embodiments, the precursor film may be preheated to a temperature that is about 10 to about 20 degrees below the melt temperature of the polymer, thereby facilitating stretching at higher draw ratios (also known as a “draw down ratio” or a “stretch ratio”) and preventing sticking to the rolls. The preheated precursor film exits a preheat section and enters draw section. In embodiments, in the draw section, the preheated precursor film is stretched in a machine direction at a draw ratio of greater than or equal to about 3:1 at a temperature at or below the melt temperature of the polymer to form a machine direction-oriented stretched film. In further embodiments, the draw ratio is greater than or equal to about 3.5:1, or greater than or equal to 4:1, or greater than or equal to about 5:1, or greater than or equal to about 6:1, or greater than or equal to about 7:1, or greater than or equal to about 8:1, or greater than or equal to about 9:1, or greater than or equal to about 10:1, or greater than or equal to about 11:1, or greater than or equal to about 12:1. The preheated precursor film may be stretched across a pair of heated draw rolls in an S-wrap configuration to the desired draw ratio and final film thickness. In embodiments, the heated roll and film temperature are similar to that of the preheat rolls in the preheat section. In some embodiments, the preheated precursor film is drawn up to 12:1 or even higher depending on the application. In some embodiments, the preheated precursor film is stretched in a draw ratio ranging from about 3:1 to about 12:1. In further embodiments, the preheated precursor film is stretched in a draw ratio ranging from about 3:1 to 10:1, or from 4:1 to about 10:1, or from about 4:1 to about 8:1, or from about 6:1 to about 12:1. By way of providing a further non-limiting example, for a draw ratio of 6:1, a preheated precursor film having an initial thickness of 5.75 mils would be stretched to provide a machine direction-oriented stretched film having a thickness of 0.96 mils. In the draw section of the MDO process, the gap between the two draw rolls is generally kept as narrow as possible to prevent excessive neck-in from stretching the film. In embodiments, the draw roll temperatures in the draw section may range from about 170°F to about 260°F for polyethylene based preheated precursor films. The machine direction-oriented stretched film exits the draw section and enters the annealing section. In the anneal section, the machine direction-oriented stretched film is heat-treated in order to lock-in the final properties of the film. The first annealing roll after the draw section is typically run at a reduced speed to allow for some relaxation, which helps to minimize curl and shrinkage when the film is later exposed to heat in downstream converting steps. The annealing rolls are typically set to the same temperature as the draw rolls. In embodiments, the roll temperatures in the anneal section are in the range of about 125°F to about 260°F, and in some embodiments, in the range of about 200°F to about 260°F. In some embodiments, multiple larger outer diameter rolls may be provided in the anneal section in order to increase the film-to-roll contact time, which improves annealing efficacy. The machine direction-oriented polymeric film exits the annealing section and enters a cooling section. In the cooling section, the machine direction-oriented polymeric film is cooled to ambient temperature for rewinding into roll-stock. Since the film is shrinking during this stage, cooling may be achieved in a stepdown process over 3 to 4 rolls in order to minimize the chance for forming wrinkles or surface defects. In embodiments, the roll temperature in the cooling section ranges from about 250°F down to about 140°F and, in other embodiments, from about 250°F down to about 70°F. In an embodiment, a process for making a machine direction-oriented polymeric film in accordance with the present disclosure includes co-extruding a film structure comprising a first skin layer, a core layer and a second skin layer.

In an embodiment, a process for making a machine direction-oriented polymeric film in accordance with the present disclosure includes co-extruding a film structure comprising a first skin layer, at least three core layers and a second skin layer. In some embodiments, the co-extruding is achieved via a blown film process, and in other embodiments via a cast film process. In some embodiments, the co-extruding, the preheating, the stretching, and the annealing are achieved sequentially in an in-line process. In some embodiments, the co-extruding is performed in one process, and the preheating, the stretching, and the annealing are performed in a separate process. In some embodiments, a process for making a machine direction-oriented polymeric film in accordance with the present disclosure further includes treating the machine direction-oriented polymeric film (e.g., to enhance a print surface and / or lamination surface thereof). Examples of types of treatments include but are not limited to corona, flame, and plasma treatments.

Nucleating Agents In an embodiment of the present disclosure the ethylene homopolymer composition will comprise a nucleating agent or a mixture of nucleating agents. In embodiments of the disclosure, the ethylene copolymer composition will comprise a nucleating agent or a mixture of nucleating agents. In embodiments of the disclosure, the polyethylene blend will comprise a nucleating agent or a mixture of nucleating agents. The term “nucleating agent”, as used herein, is meant to convey its conventional meaning to those skilled in the art of preparing nucleated polyolefin compositions, namely an additive that changes the crystallization behavior of a polymer as the polymer melt is cooled. A review of nucleating agents is provided in U.S. Patent Nos.5,981,636, 6,465,551 and 6,599,971, the disclosures of which are incorporated herein by reference. Nucleating agents which are commercially available and which may be added to a polyethylene polymer (e.g. the ethylene copolymer composition or the ethylene homopolymer composition) are dibenzylidene sorbital esters. Further examples of nucleating agents which may be added to a polyethylene polymer (e.g. the ethylene copolymer composition or the ethylene homopolymer composition) include the cyclic organic structures disclosed in U.S. Patent No.5,981,636 (and salts thereof, such as disodium bicyclo [2.2.1] heptene dicarboxylate); the saturated versions of the structures disclosed in U.S. Patent No.5,981,636 (as disclosed in U.S. Patent No.6,465,551; Zhao et al., to Milliken); the salts of certain cyclic dicarboxylic acids having a hexahydrophthalic acid structure (or “HHPA” structure) as disclosed in U.S. Patent No.6,599,971 (Dotson et al., to Milliken); and phosphate esters, such as those disclosed in U.S. Patent No.5,342,868 and those sold under the trade names NA-11 and NA-21 by Asahi Denka Kogyo, cyclic dicarboxylates and the salts thereof, such as the divalent metal or metalloid salts, (particularly, calcium salts) of the HHPA structures disclosed in U.S. Patent No.6,599,971. For clarity, the HHPA structure comprises a ring structure with six carbon atoms in the ring and two carboxylic acid groups which are substituents on adjacent atoms of the ring structure. The other four carbon atoms in the ring may be substituted, as disclosed in U.S. Patent No.6,599,971. An example is 1,2-cyclohexanedicarboxylicacid, calcium salt (CAS registry number 491589-22-1). Still further examples of nucleating agents which may be added to a polyethylene polymer include those disclosed in WO2015042561, WO2015042563, WO2015042562 and WO2011050042. Another nucleating agent which is commercially available and which in an embodiment of the disclosure may be added to a polyethylene polymer is talc (sold as “MICROTUFF®AG 609). A nucleating agent which is commercially available and which in an embodiment of the disclosure may be added a polyethylene polymer (e.g. the ethylene copolymer composition or the ethylene homopolymer composition) is IRGASTAB®NA 287. A nucleating agent which is commercially available and which in an embodiment of the disclosure may be added to a polyethylene polymer (e.g. the ethylene copolymer composition or the ethylene homopolymer composition) is HPN®210 M. A nucleating agent which is commercially available and which in an embodiment of the disclosure may be added to a polyethylene polymer (e.g. the ethylene copolymer composition or the ethylene homopolymer composition) is HPN 20E. Many of the above described nucleating agents may be difficult to mix a polyethylene polymer that is being nucleated and it is known to use dispersion aids, such as for example, zinc stearate, to mitigate this problem. In an embodiment of the disclosure, the nucleating agents are well dispersed in a polyethylene polymer. In an embodiment of the disclosure, the amount of nucleating agent used is comparatively small--from 100 to 3,000 parts by million per weight (based on the weight of the polyethylene polymer) so it will be appreciated by those skilled in the art that some care should be taken to ensure that the nucleating agent is well dispersed. In an embodiment of the disclosure, the nucleating agent is added in finely divided form (less than 50 microns, especially less than 10 microns) to the polyethylene polymer to facilitate mixing. This type of “physical blend” (i.e. a mixture of the nucleating agent and the resin in solid form) is in some embodiments preferable to the use of a “masterbatch” of the nucleator (where the term “masterbatch” refers to the practice of first melt mixing the additive--the nucleator, in this case--with a small amount of a polyethylene polymer --then melt mixing the “masterbatch” with the remaining bulk of the polyethylene polymer). In an embodiment of the disclosure, an additive such as nucleating agent may be added to a polyethylene polymer by way of a “masterbatch”, where the term “masterbatch” refers to the practice of first melt mixing the additive (e.g. a nucleator) with a small amount of the second polyethylene, followed by melt mixing the “masterbatch” with the remaining bulk of the polyethylene polymer. In an embodiment of the disclosure, the nucleating agent, or mixture of nucleating agents comprise a salt of a dicarboxylic acid. In an embodiment, the nucleating agent, or mixture of nucleating comprises 1,2- cyclohexanedicarboxylic acid, as a calcium salt (CAS registry number 491589-22-1). In an embodiment, the nucleating agent, or mixture of nucleating agents is 1,2- cyclohexanedicarboxylic acid, as a calcium salt (CAS registry number 491589-22-1) mixed with zinc stearate. In embodiments, the nucleating agent, or mixture of nucleating agents is added in an amount of from 50 to 5,000 ppm, or from 100 to 4,000 ppm, or from 200 to 4,000 ppm, or from 100 to 3,000 ppm, or from 200 to 3,000 ppm, or from 100 to 2,000 ppm, or from 200 to 2,000 ppm, or from or from 500 to 5,000 ppm, or from 500 to 4,000 ppm, or from 500 to 3,000 ppm, or from 500 to 2,000 ppm or from 500 to 1,500 ppm, based on the weight of a polyethylene polymer (e.g. the ethylene copolymer composition or the ethylene homopolymer composition). In embodiments of the present invention, a polyethylene blend used to make at least one layer in a machine direction oriented (MDO) film will contain relatively small amounts of a nucleating agent (or mixture of nucleating agents), such as, for example about 750 ppm or fewer of a nucleating agent or a mixture of nucleating agents, where ppm is parts per million, based on the wight of the polyethylene blend. In embodiment of the disclosure, the polyethylene blend comprises fewer than 750 ppm of a nucleated agent or a mixture of nucleating agents (based on the weight of the polyethylene blend). In further embodiments, the polyethylene blend comprises from 50 to 750 ppm, or from 50 to 500 ppm, or from 50 to 250 ppm, or from 50 to 200 ppm, or from 50 to 160 ppm, or from 60 to 160 ppm, or from 50 to 150 ppm, or from 60 to 150, or from 50 to 120 ppm, or from 60 to 120 ppm of a nucleated agent or a mixture of nucleating agents (based on the weight of the polyethylene blend).

Such other, polyethylene polymers may be selected from the group consisting of LLDPE, MDPE, VLDPE and mixtures thereof. Very Low Density Polyethylene (VLDPE) As used herein, the terms “very low density polyethylene” and “VLDPE” refer to an ethylene copolymer having a density of less than about 0.910 g / cm3, or about 0.910 g / cm3. The very low density polyethylenes include plastomers and elastomers. In embodiments, the VLDPE has a density of from about 0.870 g / cm3to about 0.910 g / cm3, or from about 0.880 g / cm3to about 0.910 g / cm3, or from about 0.890 to about 0.910 g / cm3.

In an embodiment, the LLDPE is a linear polymer that contains a minimal amount or relatively small amount, or undetectable amounts of long chain branching. In an embodiment, the LLDPE may comprise long chain branching. As used herein, “long chain branching” means branches having a chain length greater than that of any short chain branches, which are a result of comonomer incorporation. In embodiments, the long chain branch can be about the same length or as long as the length of the polymer backbone. Long chain branching (LCB) can be determined by conventional techniques known in the industry, such as 13C nuclear magnetic resonance (13C NMR) spectroscopy, and can be quantified using, for example, the method of Randall (Rev. Macromol. Chem. Phys., C29 (2 & 3), p.285-297). Two other methods that may be used include gel permeation chromatography coupled with a low angle laser light scattering detector (GPC-LALLS), and gel permeation chromatography coupled with a differential viscometer detector (GPC-DV). The use of these techniques for long chain branch detection, and the underlying theories, have been well documented in the literature. See, for example, Zimm, B. H. and Stockmayer, W. H., J. Chem. Phys., 17, 1301 (1949) and Rudin A., Modern Methods of Polymer Characterization, John Wiley & Sons, New York (1991), pp.103-112.

EXAMPLES Polymer Characterization and Test Methods Prior to testing, each polymer specimen was conditioned for at least 24 hours at 23 ±2°C and 50 ±10% relative humidity and subsequent testing was conducted at 23 ±2°C and 50 ±10% relative humidity. Herein, the term “ASTM conditions” refers to a laboratory that is maintained at 23 ±2°C and 50 ±10% relative humidity; and specimens to be tested were conditioned for at least 24 hours in this laboratory prior to testing. ASTM refers to the American Society for Testing and Materials. Density Polymer densities were determined using ASTM D792-13 (November 1, 2013). Melt Index Polymer melt index was determined using ASTM D1238 (August 1, 2013). Melt indexes, I2, I6, I10and I21were measured at 190°C, using weights of 2.16 kg, 6.48 kg, 10 kg and a 21.6 kg respectively. Herein, the term “stress exponent” or its acronym “S.Ex.”, is defined by the following relationship: S.Ex.= log (I6 / I2) / log(6480 / 2160) wherein I6and I2are the melt flow rates measured at 190°C using 6.48 kg and 2.16 kg loads, respectively. In this disclosure, melt index was expressed using the units of g / 10 minutes or g / 10 min or dg / minutes or dg / min; these units are equivalent. Gel Permeation Chromatography (GPC) Polymer samples (polymer) solutions (1 to 3 mg / mL) were prepared by heating the polymer in 1,2,4-trichlorobenzene (TCB) and rotating on a wheel for 4 hours at 150°C in an oven. An antioxidant (2,6-di-tert-butyl-4-methylphenol (BHT)) was added to the mixture in order to stabilize the polymer against oxidative degradation. The BHT concentration was 250 ppm. Polymer solutions were chromatographed at 140°C on a PL 220 high-temperature chromatography unit equipped with four Shodex columns (HT803, HT804, HT805 and HT806) using TCB as the mobile phase with a flow rate of 1.0 mL / minute, with a differential refractive index (DRI) as the concentration detector. BHT was added to the mobile phase at a concentration of 250 ppm to protect GPC columns from oxidative degradation. The sample injection volume was 200 µL. The GPC columns were calibrated with narrow distribution polystyrene standards. The polystyrene molecular weights were converted to polyethylene molecular weights using the Mark-Houwink equation, as described in the ASTM standard test method D6474-12 (December 2012). The GPC raw data were processed with the Cirrus GPC software, to produce molar mass averages (Mn, Mw, Mz in units of g / mol) and molar mass distribution (e.g. Polydispersity, Mw / Mn). In the polyethylene art, a commonly used term that is equivalent to GPC is SEC, i.e. Size Exclusion Chromatography. GPC-FTIR Polyethylene compositions (polymer) solutions (2 to 4 mg / mL) were prepared by heating the polymer in 1,2,4-trichlorobenzene (TCB) and rotating on a wheel for 4 hours at 150°C in an oven. The antioxidant 2,6-di-tert-butyl-4-methylphenol (BHT) was added to the mixture in order to stabilize the polymer against oxidative degradation. The BHT concentration was 250 ppm. Sample solutions were chromatographed at 140°C on a Waters GPC 150C chromatography unit equipped with four Shodex columns (HT803, HT804, HT805 and HT806) using TCB as the mobile phase with a flow rate of 1.0 mL / minute, with a FTIR spectrometer and a heated FTIR flow through cell coupled with the chromatography unit through a heated transfer line as the detection system. BHT was added to the mobile phase at a concentration of 250 ppm to protect SEC columns from oxidative degradation. The sample injection volume was 300 µL. The raw FTIR spectra were processed with OPUS FTIR software and the polymer concentration and methyl content were calculated in real time with the Chemometric Software (PLS technique) associated with the OPUS. Then the polymer concentration and methyl content were acquired and baseline-corrected with the Cirrus GPC software. The SEC columns were calibrated with narrow distribution polystyrene standards. The polystyrene molecular weights were converted to polyethylene molecular weights using the Mark-Houwink equation, as described in the ASTM standard test method D6474. The comonomer content was calculated based on the polymer concentration and methyl content predicted by the PLS technique as described in Paul J. DesLauriers, Polymer 43, pages 159-170 (2002); herein incorporated by reference. Short Chain Branching – GPC-FTIR Short chain branches per 1000 carbon atoms, is measured relative to the copolymer fractions of different molecular weights. When plotted on a semi-logarithmic scale graph, the sloping line (from low molecular weight fractions to high molecular weight fractions on the logarithmic horizontal X-axis and the number of short chain branches on the vertical y- axis) is the short chain branching distribution determined by Fourier Transform Infra-Red (FTIR) spectrometry for the different molecular weight fractions. The GPC-FTIR method measures total methyl content, which includes the methyl groups located at the ends of each macromolecular chain, i.e. methyl end groups. Thus, the raw GPC-FTIR data must be corrected by subtracting the contribution from methyl end groups. To be more clear, the raw GPC-FTIR data overestimates the amount of short chain branching (SCB) and this overestimation increases as molecular weight (M) decreases. In this disclosure, raw GPC- FTIR data was corrected using the 2-methyl correction. At a given molecular weight (M), the number of methyl end groups (NE) was calculated using the following equation; NE = 28000 / M, and NE(M dependent) was subtracted from the raw GPC-FTIR data to produce the SCB / 1000C (2-Methyl Corrected) GPC-FTIR data. Unsaturation Content The quantity of unsaturated groups, i.e., double bonds, in a polyethylene composition was determined according to ASTM D3124-98 (vinylidene unsaturation, published March 2011) and ASTM D6248-98 (vinyl and trans unsaturation, published July 2012). An ethylene interpolymer sample was: a) first subjected to a carbon disulfide extraction to remove additives that may interfere with the analysis; b) the sample (pellet, film or granular form) was pressed into a plaque of uniform thickness (0.5 mm), and; c) the plaque was analyzed by FTIR. Comonomer Content: Fourier Transform Infrared (FTIR) Spectroscopy The quantity of comonomer in a polyethylene composition was determined by FTIR and reported as the Short Chain Branching (SCB) content having dimensions of CH3# / 1000C (number of methyl branches per 1000 carbon atoms). This test was completed according to ASTM D6645-01 (2001), employing a compression molded polymer plaque and a Thermo-Nicolet 750 Magna-IR Spectrophotometer. The polymer plaque was prepared using a compression molding device (Wabash-Genesis Series press) according to ASTM D4703-16 (April 2016). Differential Scanning Calorimetry (DSC) DSC testing was conducted in general accordance with ASTM D3418. This analysis is performed by subjecting a polymer sample (5-10mg prepared in an aluminum pan) and a reference material (empty aluminum pan) to a constant rate of temperature change within the DSC cell. The actual temperatures of the sample and reference are monitored by the instrument as the sample temperature is increased or decreased linearly with time. If the sample undergoes a transition, reaction, or transformation, the rate at which its temperature changes will differ from that of the reference. The instrument (TA Instruments Q2000 ) was first calibrated with indium; after the calibration, a polymer specimen is equilibrated at 0oC and then the temperature was increased to 200°C at a heating rate of 10°C / min; the melt was then kept isothermally at 200°C for five minutes; the melt was then cooled to 0°C at a cooling rate of 10°C / min and kept at 0°C for five minutes; the specimen was then heated to 200°C at a heating rate of 10°C / min. The difference in temperature between the sample and reference (DT = Treference - Tsample) is then plotted against the sample temperature to produce a differential thermogram. From this plot, the melting peak temperatures (^C), enthalpy of fusion (J / g) and crystallinity (%) was determined. Dynamic Mechanical Analysis (DMA) Oscillatory shear measurements under small strain amplitudes were carried out to obtain linear viscoelastic functions at 190°C under N2atmosphere, at a strain amplitude of 10% and over a frequency range of 0.02-126 rad / s at 5 points per decade. Frequency sweep experiments were performed with a TA Instruments DHR3 stress-controlled rheometer using cone-plate geometry with a cone angle of 5°, a truncation of 137 μm and a diameter of 25 mm. In this experiment a sinusoidal strain wave was applied and the stress response was analyzed in terms of linear viscoelastic functions. The zero shear rate viscosity (^0) based on the DMA frequency sweep results was predicted by Ellis model (see R.B. Bird et al. “Dynamics of Polymer Liquids. Volume 1: Fluid Mechanics” Wiley-Interscience Publications (1987) p.228) or Carreau-Yasuda model (see K. Yasuda (1979) PhD Thesis, IT Cambridge). The dynamic rheological data were analyzed using the rheometer software (viz., Rheometrics RHIOS V4.4 or Orchestrator Software) to determine the melt elastic modulus G′(G″=500) at a reference melt viscous modulus (G″) value of G″=500 Pa. If necessary, the values were obtained by interpolation between the available data points using the Rheometrics software. The shear thinning index, SHI(0.5,50) was calculated as the ratio of the complex viscosities estimated at shear stress of 0.5 kPa over that estimated at a shear stress of 50 kPa. The shear thinning index, SHI(0.5,50) provides information on the shear thinning behavior of the polymer melt. A high value indicates a strong dependence of viscosity with changes in deformation rate (shear or frequency). CYTSAF / TREF (CTREF) The “Composition Distribution Breadth Index”, hereinafter CDBI, of a polymer sample was measured using a CRYSTAF / TREF 200+ unit equipped with an IR detector, hereinafter the CTREF. The acronym “TREF” refers to Temperature Rising Elution Fractionation. The CTREF was supplied by Polymer Characterization, S.A. (Valencia Technology Park, Gustave Eiffel, 8, Paterna, E-46980 Valencia, Spain). The CTREF was operated in the TREF mode, which generates the chemical composition of the polymer sample as a function of elution temperature, the Co / Ho ratio (Copolymer / Homopolymer ratio) and the CDBI (the Composition Distribution Breadth Index), i.e. CDBI50and CDBI25. A polymer sample (80 to 100 mg) was placed into the reactor vessel of the CTREF. The reactor vessel was filled with 35 ml of 1,2,4-trichlorobenzene (TCB) and the polymer was dissolved by heating the solution to 150^C for 2 hours. An aliquot (1.5 mL) of the solution was then loaded into the CTREF column which was packed with stainless steel beads. The column, loaded with sample, was allowed to stabilize at 110^C for 45 minutes. The polymer was then crystallized from solution, within the column, by dropping the temperature to 30^C at a cooling rate of 0.09^C / minute. The column was then equilibrated for 30 minutes at 30°C. The crystallized polymer was then eluted from the column with TCB flowing through the column at 0.75 mL / minute, while the column was slowly heated from 30°C to 120^C at a heating rate of 0.25^C / minute. The raw CTREF data were processed using Polymer Char software, an Excel spreadsheet and CTREF software developed in-house. CDBI50was defined as the percent of polymer whose composition is within 50% of the median comonomer composition; CDBI50 was calculated from the composition distribution cure and the normalized cumulative integral of the composition distribution curve, as described in United States Patent 5,376,439. Those skilled in the art will understand that a calibration curve is required to convert a CTREF elution temperature to comonomer content, i.e. the amount of comonomer in the ethylene / ^-olefin polymer fraction that elutes at a specific temperature. The generation of such calibration curves are described in the prior art, e.g. Wild, et al., J. Polym. Sci., Part B, Polym. Phys., Vol.20 (3), pages 441-455: hereby fully incorporated by reference. CDBI25as calculated in a similar manner; CDBI25 is defined as the percent of polymer whose composition is with 25% of the median comonomer composition. At the end of each sample run, the CTREF column was cleaned for 30 minutes; specifically, with the CTREF column temperature at 160^C, TCB flowed (0.5 mL / minute) through the column for 30 minutes. Hexane Extractables Hexane extractables was determined according to the Code of Federal Registration 21 CFR §177.1520 Para (c) 3.1 and 3.2; wherein the quantity of hexane extractable material in a sample is determined gravimetrically. Film Opticals Film optical properties were measured as follows: Haze was measured accordingly to ASTM D1003-13 (November 15, 2013). Gloss was determined by ASTM D2457-13. Film Mechanical Properties Tensile tests in both machine and transverse directions (MD and TD, respectively) were conducted in general compliance with ASTM D882-18. The width of the specimen used for the tensile property measurement was 1.0 inch. The initial stretching speed is 1.0 inch / min to 5% Strain and then the speed was increased to 20.0 inches / min until break. The grip separation was 2.0 inches. Mechanical properties measured are tensile break stress (reported in MPa), strain at yield (%), yield stress (MPa), strain at break (%), break stress (MPa). The elastic modulus (MPa) was measured using 1.0 inch wide specimens, 2 inch grip separation at a test speed of 1.0 inch / min. Film Thickness Film thickness for the stretched multilayer films was measured according to ASTM D 6988-13. The Ethylene Copolymer Composition An ethylene copolymer composition, “Copolymer” was made substantially according to disclosures made in U.S. Pat. No.8,962,755. The ethylene copolymer composition used in the present examples had a density of 0.953 g / cm3, a melt index (I2) of 1.5 g / 10min, and a molecular weight distribution (Mw / Mn) of 8.15. The Ethylene Homopolymer Composition An ethylene homopolymer composition “Homopolymer” was made substantially according to disclosures made in U.S. Pat. Application Publication No. US2013 / 0225743 or US2008 / 0118749 as well as according to the teaching of U.S. Provisional Appl. No. 63 / 023,270. The ethylene homopolymer composition used in the present examples had a density of 0.967 g / cm3, a melt index (I2) of 1.2 g / 10min, a molecular weight distribution (Mw / Mn) of 8.5. The ethylene homopolymer composition was nucleated with 1,200 ppm (parts per million by weight) of HYPERFORM HPN-20E which is commercially available from Milliken. The nucleating agent is reported to be a combination of a) a calcium salt of HHPA and b) zinc stearate, in a 2 / 1 weight ratio. To nucleate a polyethylene homopolymer composition, a HYPERFORM HPN-20E masterbatch was made and the masterbatch let down at an appropriate level and melt compounded into the polyethylene homopolymer composition. Further details for the ethylene copolymer and the ethylene homopolymer compositions are shown in Table 1.

All the components were blended simultaneously using a continuous on-line blending. Machine direction oriented films were produced using integrated and in-line blown extrusion and MDO equipment (i.e. the multilayer blown film structure was prepared on a blown film line operated in a sequence with downstream machine direction orientation equipment). Five-layer films were prepared on the blown film line, followed by machine direction orientation (MDO). For convenience, the five layers may be referred to as A / B / C / D / E—with layers A and E being the external layers, also referred to herein as “skin” layers, layer C being a core layer, and layers B and D being intermediate (also referred to herein as “core”) layers.
