Description

Technical Field

[0001] This creation relates to a package including one or more packaging units.

Background Art

[0002] Some products are sold in independent small packages (such as cigarettes, soaps, etc.). In order to improve the efficiency during transportation, a plurality of independent small packages are repackaged together for shipment and are transported in a shape such as a long and narrow box.

[0003] Also, in order to fix these independent small packages and make the whole package waterproof, moisture-proof, and oil-resistant after packaging to facilitate transportation and storage, usually, these independent small packages are placed in a carton and wrapped with a plastic film.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, this process requires a two-step working procedure, and since these two-step working procedures need to be completed using different equipment, a considerable amount of time, labor, and material costs are required.

Means for Solving the Problems

[0005] In contrast, this invention has the following configuration.

[0006] In a package including a packaging unit and a laminate, a plastic film covers the packaging unit, the laminate covers the outside of the packaging unit, the laminate includes a base material and a plastic layer, the softening temperature of the plastic layer is lower than the softening temperature of the plastic film, and the softening temperature of the plastic layer and the softening temperature of the plastic film are measured based on ASTM D1525. A part of the laminate overlaps on another part of the laminate, and a part of the laminate is adhered to the other part of the laminate by the plastic layer.

[0007] In addition, the plastic film on the packaging unit includes polyethylene, polypropylene, polyvinyl chloride, polylactic acid, ethylene vinyl acetate, acrylic copolymer resin, polyester, or polyamide.

[0008] In addition, the plastic layer of the laminate includes polyethylene, polypropylene, polyvinyl chloride, polylactic acid, ethylene vinyl acetate, acrylic copolymer resin, polyester, or polyamide.

[0009] In addition, the softening temperature of the plastic layer in the laminate is in the range of 50°C to 150°C, and the softening temperature of the plastic film is in the range of 150°C to 200°C.

[0010] In addition, the plastic film on the packaging unit is a biaxially stretched polypropylene film, and the plastic layer of the laminate contains polyethylene.

[0011] In addition, the plastic layer of the laminate contains high-density polyethylene and low-density polyethylene.

[0012] In addition, the base material of the laminate includes paper, wood chips, metal, carbon fiber, aromatic polyamide fiber, silicon carbide fiber, alumina fiber, boron fiber, tungsten carbide fiber, glass fiber, or a combination thereof.

[0013] In addition, the laminate includes a printing layer, and the printing layer is located between the base material and the plastic layer, or the base material is located on a surface away from the plastic layer.

[0014] In addition, the laminate is (a) According to the measurement method of GB / T 451.2, the total grammage of the laminate is 35.0 g / m 2~150.0 g / m 2 and (b) According to the measurement method of GB / T 24218.2-2009, the overall thickness of the laminate is 0.05 mm to 0.20 mm, (c) According to the measurement method of GB / T 36392, the coating amount of the plastic layer in the laminate is 5.0 g / m 2 ~130.0 g / m 2 and (d) According to the measurement method of GB7974, the brightness of the laminate is ≧80.0%, (e) According to the measurement method of GB7974, the fluorescence brightness of the laminate is ≦1.0%, (f) According to the measurement method of GB / T 12914, the longitudinal tensile strength of the laminate is 3.0 kN / m to 5.0 kN / m, (g) According to the measurement method of GB / T 455, the transverse tear strength of the laminate is 280.0 mN to 350 mN, (h) According to the measurement method of GB / T 456, the smoothness of the laminate is 300.0 s to 350 s, (i) According to the measurement method of GB / T 742, the ash content of the laminate is ≦7.0%, (j) According to the measurement method of GB / T 462, the moisture content of the laminate is 4% to 8%, (k) According to the measurement method of GB / T 1541, the dustiness of the laminate is such that the number of dust particles with a size of 0.2 mm 2 ~1.5 mm 2 is ≦20 pieces / m 2 and the number of black dust particles with a size of ≧1.5 mm 2 is 0 pieces / m 2 and (l) According to the measurement method in Appendix A of GB / T 36392, the adhesion between the plastic layer and the substrate is ≧85.0%, and it has at least one of the above properties.

[0015] In addition, the laminate has all the properties of (a) to (l) above.

Advantages of the Invention

[0016] Since the package of the present application has the technical feature that "the softening temperature of the plastic layer is lower than the softening temperature of the plastic film", when forming the package by heat-sealing the laminate, the plastic layer of the laminate can be softened, but the plastic film of the packaging unit can be heated at a temperature at which the plastic film does not soften, and the effect of adhering between the laminates can be obtained without damaging the plastic film on the packaging unit.

[0017] That is, the package of the present application can be formed by packaging the packaging unit only with the laminate. Therefore, in some embodiments, it is not necessary to first put the packaging unit into a carton and then cover the carton with a plastic film again, and the properties of the laminate itself can be utilized to complete a package with waterproof, moisture-proof, and oil-resistant functions.

[0018] From the above, the present creation provides a package that can be formed without using a carton and the plastic film outside thereof, can realize the fixation of a plurality of independent small packages (hereinafter referred to as packaging units), and maintains the functions of waterproofing, moisture-proofing, and oil resistance as a whole.

[0019] Furthermore, it does not require a two-step working procedure and can complete the required package with a single piece of equipment, thereby reducing the purchase cost of manufacturing equipment, labor costs, and production time costs.

[0020] On the other hand, compared with the package using a carton and a plastic film, the package of the present creation can not only reduce the material cost, but also reduce the transportation cost by reducing the overall weight.

[0021] In addition, in order to make the packaging unit itself have waterproof, moisture-proof, and oil-resistant functions and sell it separately, as described above, there is also a plastic film on the outside of the packaging unit.

[0022] For a packaging unit equipped with such a plastic film, a person skilled in the art would not consider using a laminated material (such as laminated paper) having a plastic layer as the outer packaging material of the packaging unit.

[0023] The reason is that generally, it is considered that the plastic layer of the laminated material needs to be exposed to high temperatures to obtain adhesive strength. At such high temperatures, the plastic film on each internal packaging unit will also be softened, and unwanted adhesion may occur between packaging units or between the packaging unit and the laminated material, thereby damaging the integrity of the appearance of the packaging unit.

[0024] However, due to the technical features described in this creation, this creation overcomes the above technical problems and enables packaging a packaging unit equipped with a plastic film with a laminated material having a plastic layer, expanding the possibilities of the package.

Mode for Carrying Out the Invention

[0026] In the following description, for the sake of simplifying the description of this creation, specific examples of each component and its arrangement will be described. However, it should be understood that these embodiments do not limit the technical scope of the present invention.

[0027] For example, when it is described in the specification that the first component is formed on or above the second component, that is, it also includes the aspect where the first component and the second component are in direct contact, but it is also possible to include embodiments in which other additional components are formed between the first component and the second component so that the first component and the second component are not in direct contact.

[0028] Unless otherwise specified, expressions such as "including", "comprising", and "having" used in this specification are in an open form and should be interpreted as meaning "including but not limited to ~".

[0029] The terms indicating directions such as "under...", "below", "lower", "above...", "above", "higher" and expressions similar thereto described in this specification are used to facilitate the description of the relationship between an element in the drawing and other elements.

[0030] These spatially relative terms include different orientations of the device during use or operation, and the orientations shown in the drawings. And when the device rotates in different directions, the adjectives related to the space used are also interpreted based on the rotated directions.

[0031] Unless otherwise specified, the term "or" as used herein is used to mean non-exclusive "or", and "A or B" includes "A but not B (or A exists but B does not exist)", "B but not A (or B exists but A does not exist)", and "A and B (both A and B exist)".

[0032] The description "from a certain numerical value to another numerical value" in this specification is a summary display method to avoid listing all the numerical values within the range in the specification one by one.

[0033] Therefore, unless there are special additional instructions, or unless it is clearly contrary to the reasonable common sense in the technical field to which the present invention pertains, the specific numerical range described in the specification of this application is equivalent to describing any numerical value within that numerical range, and any smaller numerical range defined by any numerical value within that numerical range (including its significant digits and the next significant digit). This is the same as if any numerical value and a smaller numerical range than it were explicitly described in the specification.

[0034] For example, if the specification describes "1 to 10", regardless of whether other values are described, it is equivalent to describing ranges such as "3 to 5" and "2.5 to 6.8".

[0035] First, it will be described with reference to FIGS. 1A, 1B, and 1C. Here, FIGS. 1A, 1B, and 1C are diagrams for explaining the manufacturing process of an embodiment of the package 100 of the present invention, and are schematic diagrams showing the states at different stages. As shown in FIGS. 1A, 1B, and 1C, the package 100 is formed by covering at least one packaging unit 110 with a laminate 120.

[0036] In the manufacturing process of this embodiment, a plurality of packaging units 110 are arranged on the laminate 120 (as shown in FIG. 1A), and then the laminate 120 is folded so that a part 120a of the laminate 120 overlaps another part 120b of the laminate 120 to cover the packaging unit 110. Then, by applying a predetermined temperature to the laminate 120 (to be described later), a part 120a of the laminate 120 is attached to another part 120b of the laminate 120 (as shown in FIGS. 1B and 1C), and thus the package 100 is obtained.

[0037] In order to form the package 100 by overlapping and laminating the laminates 120, in some embodiments, as shown in FIG. 1C, the package 100 has a joining line (seam) 120c.

[0038] The shape or item of the packaging unit 110 is not particularly limited, and it may be, for example, a rectangular parallelepiped cigarette box, soap in a box, etc. As shown in the partial enlarged view of the packaging unit 110 in FIG. 1A', the outside of the packaging unit 110 is covered with a plastic film 111.

[0039] Thereby, each packaging unit 110 can be provided with waterproof, moisture-proof, and oil-proof functions, and it becomes easy to sell them individually. Note that both the plastic film 111 and the laminate 120 are covered on the packaging unit 110. However, the laminate 120 is on the outside of the plastic film 111, that is, the laminate 120 is farther away from the packaging unit 110 than the plastic film 111.

[0040] To further explain the laminate 120, please refer to FIG. 2. FIG. 2 is a cross-sectional view drawn based on the laminate 120 in an embodiment of the package 100 of the present invention. In addition to FIG. 2, it will be described with reference to FIG. 1A'.

[0041] In this embodiment, the laminate 120 has a base material 121 and a plastic layer 122. The softening temperature T 122 of the plastic layer 122 is the softening temperature T 111Lower than this. Here, the softening temperature is measured based on ASTM D1525, that is, it measures the temperature of the test piece when a standard needle is pierced into the test piece to a certain depth under a certain load.

[0042] The material of the plastic layer 122 in the laminate 120 and the material of the plastic film 111 covering the outside of the packaging unit 110 shown in FIG. 1A' may include a thermoplastic.

[0043] In some embodiments, the plastic layer 122 and the plastic film 111 may include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polylactic acid (PLA), ethylene vinyl acetate (EVA), acrylic copolymer resin, polyester (e.g., polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), or polyamide (nylon-6, nylon-66, polymetaxylene adipamide, etc.).

[0044] In some embodiments, the plastic film 111 covering the outside of the packaging unit 110 may be a non-stretchable film or a stretchable film. For example, it may be a biaxially stretched film stretched in both the longitudinal direction and the width direction.

[0045] The plastic layer 122 and the plastic film 111 are selected as appropriate materials for forming and conforming based on the condition that the softening temperature T 122 of the plastic layer 122 is lower than the softening temperature T 111 of the plastic film 111.

[0046] In some embodiments, the softening temperature T 122 of the plastic layer 122 of the laminate 120 is in the range of 50°C to 150°C, and the softening temperature T 111It is within the range of 150°C to 200°C (for example, within the range of 155°C to 200°C).

[0047] For example, the plastic layer 122 in the laminate 120 may contain polyethylene, and the plastic film 111 may be a biaxially oriented polypropylene (BOPP) film.

[0048] In some embodiments, the plastic layer 122 and the plastic film 111 may have mixed components in order to adjust other properties such as the softening temperature or mechanical properties.

[0049] For example, the plastic layer 122 of the laminate 120 may contain high-density polyethylene (HDPE) and low-density polyethylene (LDPE), and the plastic film 111 may be a biaxially oriented polypropylene (BOPP) film.

[0050] The density of the high-density polyethylene (HDPE) is 0.9415 g / m 3 ~0.965 g / m 3 and a density lower than this range is low-density polyethylene (LDPE), for example 0.9105 g / m 3 ~0.9255 g / m 3 and may be acceptable.

[0051] In some embodiments, various additives can be added as long as the properties of the plastic layer 122 of the laminate 120 and the plastic film 111 covering the outside of the packaging unit 110 do not become lower than the required level.

[0052] Examples include antioxidants, heat stabilizers, weather stabilizers, lubricants (such as paraffin, white oil, stearic acid, stearates, etc.), ultraviolet absorbers, organic smoothing agents, pigments, dyes, organic or inorganic particles, fillers (such as calcium hydroxide, talc, calcium sulfate, etc.), antistatic agents, and the like.

[0053] As the base material 121 of the laminate 120, paper, wood chips, metal, carbon fiber, aromatic polyamide fiber, silicon carbide fiber, alumina fiber, boron fiber, tungsten carbide fiber, glass fiber, or any material on which a film can be formed may be mentioned.

[0054] A continuous plastic layer 122 can be formed on the base material 121. As long as the plastic layer 122 of the laminate 120 does not suffer obvious damage when heated later, the technical scope of the present invention does not limit the material of the base material 121. In some embodiments, the base material 121 of the laminate 120 is paper.

[0055] For the laminate 120 of the present application, after heating and melting the raw material of the plastic layer 122, it is applied on the base material 121 by various coating methods such as knife coating, gravure roller coating, slit coating, spray coating, screen coating, etc. After cooling and drying, the plastic layer 122 is formed and the laminate 120 is obtained.

[0056] The melting temperature can melt and flow the raw material, but it can be selected according to the raw material used within the range where the raw material does not crack.

[0057] In some embodiments, when the plastic layer 122 of the laminate 120 contains polyethylene, polyethylene may be heated to 50°C to 150°C and melted, or from the viewpoints of ease of processing and energy saving, polyethylene may be heated to 90°C to 120°C and melted.

[0058] When the raw material of the plastic layer 122 is a mixture, the components may be first mixed and then melted, or further, the components may be first melted and then mixed. The formed laminate 120 can be made into single sheets die-cut for subsequent use after inspection and burr trimming, or can be wound into a roll.

[0059] In some embodiments, in order to improve adhesion, the bonding surface of the base material 121 of the laminate 120 can be subjected to a surface activation treatment.

[0060] Examples of the surface activation treatment include corona treatment, plasma treatment, discharge treatment (such as glow discharge treatment), ozone treatment, UV ozone treatment, ionization active ray treatment (such as ultraviolet treatment, electron beam treatment), and the like.

[0061] In some embodiments, the laminate 120 has a printed layer 123 formed, for example, by printing or inkjet printing. As a result, the laminate 120 can present a desired pattern or text such as a trademark, texture, warning, barcode, etc., and the laminate 120 or the package 100 can have a desired appearance.

[0062] Specifically, it will be described with reference to FIGS. 3A and 3B. Here, FIG. 3A is a cross-sectional view drawn based on the laminate 120 in another embodiment of the package 100 of the present invention, and FIG. 3B is a cross-sectional view drawn based on the laminate 120 in another embodiment of the package 100 of the present invention.

[0063] Among these, in the embodiment shown in FIG. 3A, the printed layer 123 is located on the side closer to the plastic layer 122 of the base material 121, for example, between the base material 121 and the plastic layer 122. Since the printed layer 123 is disposed between the plastic layer 122 and the base material 121, it is difficult to peel off and fall off from the laminate 120.

[0064] On the other hand, in some embodiments, as shown in FIG. 3B, the printed layer 123 is located on the side (the lower side in FIG. 3B) away from the plastic layer 122 in the base material 121.

[0065] When the laminate 120 is formed on the package 100 with the plastic layer 122 facing the inside of the package 100, by forming the printed layer 123 on the side away from the plastic layer 122 of the base material 121, the result of printing can be displayed and identified on the outside of the package 100.

[0066] Note that the printing layer 123 may be formed either before or after forming the plastic layer 122, depending on the case.

[0067] For example, in the embodiment shown in FIG. 3B, the printing layer 123 can be formed before or after the plastic layer 122 is formed. In the embodiment shown in FIG. 3A, first, the printing layer 123 needs to be formed, and then the plastic layer 122 is formed.

[0068] Note that as long as the plastic layer 122 is the outermost layer of the laminate 120, whether the plastic layer 122 faces the inside or the outside of the package 100 is not particularly limited.

[0069] In some embodiments, when heating and attaching the laminate 120, after the package 100 is formed, the plastic layer 122 faces the inside of the package 100 in order to facilitate the overall movement and processing.

[0070] In other embodiments, after the package 100 is formed, the plastic layer 122 faces the outside of the package 100. Thereby, the base material 121 is prevented from being wetted by oil or water, and when the package 100 is exposed to water or oil, the integrity of the appearance can be maintained better.

[0071] Furthermore, in some embodiments, the laminate 120 has at least one of the following characteristics.

[0072] (a) According to the measurement method of GB / T 451.2, the total grammage (Weight) of the laminate 120 is 35.0 g / m 2 ~150.0 g / m 2 In this way, the entire laminate 120 can be easily processed, has a reasonable cost, and at the same time can have an appropriate strength to maintain the package 100. Preferably, the total grammage of the laminate 120 is 50.0 g / m 2 ~95.0 g / m 2 and may be, more preferably, 60.0 g / m 2 ~70.0 g / m2 It can be.

[0073] (b) According to the measurement method of GB / T24218.2-2009, the overall thickness of the laminate 120 is 0.05 mm to 0.20 mm. Preferably, the overall thickness of the laminate 120 is 0.06 mm to 0.15 mm, and the laminate 120 can have better mechanical strength and processability.

[0074] (c) According to the measurement method of GB / T36392, the coating weight of the plastic layer 122 in the laminate 120 is 5.0 g / m 2 ~130.0 g / m 2 and preferably, the coating amount of the plastic layer 122 in the laminate 120 is 10.0 g / m 2 ~80.0 g / m 2 It can be, and as a result, the laminate 120 can have sufficient components of the plastic layer 122 to form a more uniform plastic layer 122, obtain better waterproof and oil resistance effects, and obtain the best adhesion effect at a reasonable cost.

[0075] (d) According to the measurement method of GB7974, the brightness (or "luminance") of the laminate 120 is ≧80.0%. Preferably, the brightness of the laminate 120 is ≧85.0% so that the printed layer 123 formed on the base material 121 can have a better presentation effect.

[0076] (e) According to the measurement method of GB7974, the fluorescence brightness of the laminate 120 is ≦1.0%, that is, the laminate 120 contains little or no fluorescent whitening agent, so it has high safety for the human body.

[0077] (f) According to the measurement method of GB / T12914, the longitudinal tensile strength of the laminate 120 is 3.0 kN / m to 5.0 kN / m. To make the mechanical strength and processability of the laminate 120 better, the longitudinal tensile strength of the laminate 120 is preferably 4.0 kN / m to 5.0 kN / m.

[0078] (g) According to the measurement method of GB / T455, the transverse tear strength of the laminate 120 is 280.0 mN to 350 mN. The transverse tear strength of the laminate 120 is preferably 300.0 mN to 350 mN. Thereby, the laminate 120 has better mechanical strength and processability.

[0079] (h) According to the measurement method of GB / T456, the smoothness of the laminate 120 is 300.0 s to 350 s. To obtain a better appearance and improve the printability and printing effect, the smoothness of the laminate 120 is preferably 320.0 s to 350 s.

[0080] (i) According to the measurement method of GB / T742, the ash content of the laminate 120 is ≤ 7.0%. Preferably, the ash content of the laminate 120 is ≤ 5.0%.

[0081] (j) According to the measurement method of GB / T462, the moisture content of the laminate 120 is 4% to 8%. Preferably, the moisture content of the laminate 120 can be 5% to 7%. As a result, the laminate 120 can have better flatness, maintain mechanical strength, and have mold resistance.

[0082] (k) According to the measurement method of GB / T1541, the dustiness of the laminate 120 is such that the number of dust particles with a size of 0.2 mm 2 ~1.5 mm 2 is ≤ 20 pieces / m 2 and the number of black dust particles with a size of ≥ 1.5 mm 2 is 0 pieces / m 2 so that a better appearance can be obtained.

[0083] (l) According to the measurement method in Appendix A of GB / T 36392, the degree of bonding between the plastic layer 122 and the base material 121 is ≧85.0%, preferably, the degree of bonding between the plastic layer 122 and the base material 121 is ≧95.0%. Thereby, the structural stability of the laminate 120 is improved, and accordingly, the blocking effect against moisture and grease is improved.

[0084] In some embodiments, the laminate 120 may have the properties within the maximum range in each of the foregoing items (a) to (l). Also, in some embodiments, the laminate 120 has the properties within a relatively good or even better range in at least one of the foregoing items (a) to (l), or even all of the foregoing items (a) to (l).

[0085] The plastic layer 122 of the laminate 120 can be softened by heating to generate viscosity. By applying a temperature to the laminate 120 and overlapping a portion 120a of the laminate 120 and another portion 120b of the laminate 120, the portion 120a of the laminate 120 and the other portion 120b of the laminate 120 can be adhered via the plastic layer 122.

[0086] The laminate 120 of the package 100 of the present application has the technical feature that "the softening temperature T of the plastic layer 122 122 is lower than the softening temperature T of the plastic film 111 111 Therefore, for example, as shown in FIGS. 1B to 1C, when performing the step of heating the laminate 120 and bonding a portion 120a of the laminate 120 and another portion 120b of the laminate 120 to form the package 100, the laminate 120 can be heated at a temperature at which the plastic layer 122 of the laminate 120 softens, but the plastic film 111 of the packaging unit 110 does not soften.

[0087] At this time, when forming the package 100, even if the plastic layer 122 of the laminate 120 and the plastic film 111 on the package 110 are heated simultaneously, only the plastic layer 122 softens, and the plastic film 111 is not affected. Due to the softening of the plastic film 111, unwanted adhesion between the packaging units 110 or between the packaging unit 110 and the laminate 120 is not caused, and the laminates 120 can be attached to each other, maintaining the integrity of the appearance of the packaging unit 110.

[0088] In other words, due to the technical feature that the softening temperature T of the plastic layer 122 122 is lower than the softening temperature T of the plastic film 111 111 the packaging unit 110 can be simply packaged by the laminate 120, and it is not necessary to put the packaging unit 110 in a carton and cover the carton with a plastic film to complete a package with waterproof, moisture-proof, and oil-resistant functions.

[0089] In addition, since the package 100 of the present invention does not require the use of a carton or a plastic film covering the carton, not only can the material cost be reduced, but also the overall weight can be reduced and the transportation cost can be suppressed.

[0090] Note that the expression "A covers B" in this application includes not only the case where A completely covers B but also the case where A covers a part of B.

[0091] Furthermore, in the embodiment shown in FIG. 1C, the laminate 120 adheres to the internal packaging unit 110 to form the package 100, and the packaging unit 110 can hardly move within the package 100.

[0092] In other embodiments, the laminate 120 is in the form of a strip surrounding and covering the packaging unit 110 to form the package 100. At this time, the packaging unit 110 can also hardly move within the package 100.

[0093] In other embodiments, the laminate 120 can also be formed in a bag shape that covers the packaging unit 110. Compared with the above two forms, in this case, the movement range of the packaging unit 110 within the package 100 becomes larger.

[0094] Next, it will be described with reference to FIGS. 1A, 1B, 1C, and 4. Here, FIG. 4 is a flowchart drawn based on an embodiment of a method for manufacturing the package 100 of the present invention.

[0095] In the present application, a method for manufacturing the package 100 is provided. In step S01(a), the laminate 120 is folded so that the laminate 120 covers the outside of the packaging unit 110, and a step of overlapping a part 120a of the laminate 120 on another part 120b of the laminate 120 is included.

[0096] In step S02(b), a first temperature T1 is applied to the laminate 120 to soften the plastic layer 122 of a part 120a of the laminate 120, and in this way, a part 120a of the laminate 120 is adhered to another part 120b of the laminate 120 through the plastic layer 122.

[0097] The first temperature T1 is higher than the softening temperature T of the plastic layer 122 122 and lower than the softening temperature T of the plastic film 111 of the packaging unit 110. That is, T 111 > T1 ≥ T 111 is satisfied. 122

[0098] It should be noted that steps S01 and S02 can be executed in order or simultaneously. That is, by folding the laminate 120 and applying the first temperature T1 to the laminate 120 at the same time, the time required for the manufacturing method can be further shortened.

[0099] In the manufacturing method of the package 100 described above, the first temperature T1 is the softening temperature T of the plastic layer 122 122 ​Therefore, when the first temperature T1 is applied to the laminate 120, the plastic layer 122 of the laminate 120 can surely soften and become sticky. Thereby, the laminates 120 can be bonded to each other to form the package 100.

[0100] At the same time, since the first temperature T1 is lower than the softening temperature T of the plastic film 111 of the packaging unit 110, even when the laminate 120 is heated at the first temperature T1, the plastic film 111 on the packaging unit 110 does not soften. Therefore, unnecessary adhesion does not occur between the packaging units 110 or between the packaging unit 110 and the laminate 120, and the appearance integrity of the packaging unit 110 is maintained. 111 Moreover, since the laminate 120 itself has waterproofness and oil resistance, by using this manufacturing method and packaging the packaging unit 110 with only the laminate 120, a package 100 having waterproofness and oil resistance functions can be formed.

[0101] Since the packaging unit 110 can be packaged with only the laminate 120, in some embodiments of the present application, first, the packaging unit 110 is placed in a carton, and then the carton is wrapped with a plastic film, so there is no need to form a package 100 having waterproofness and oil resistance.

[0102] Therefore, there is no need to cover the carton with a plastic film using a film wrapping machine after passing through the carton filling device, and the manufacturing method of the package 100 can be completed with a single device, reducing the purchase cost of manufacturing equipment, labor costs, and production time costs.

[0103] In some embodiments, the manufacturing method of the package 100 can be implemented by simply adjusting the "carton filling device" without passing through a film wrapping machine.

[0104]

[0105] ​The film wrapping machine is equipped with a film supply mechanism (such as film guide rollers), a folding mechanism (such as folding plates), and a heating element. Specific equipment includes, for example, the following. For example, a cigarette outer film wrapping machine purchased from Chi Mei Enterprise Co., Ltd., model: PM-818 can be mentioned.

[0106] The above-mentioned carton filling device has a carton folding mechanism (such as folding plates) and a stacking and filling mechanism (such as push rods or push plates). Specific equipment includes, for example, a cigarette carton wrapping machine purchased from Molins, model: HLP-2.

[0107] The above-mentioned "easily adjusting the carton filling device" includes, for example, adding a heating element for heating the laminate 120 inside the carton filling device, so that when the carton filling device folds the laminate 120, the first temperature T1 can be applied to at least a part of the laminate 120. In this way, a part 120a of the laminate 120 is adhered to another part 120b of the laminate 120 through the softened plastic layer 122.

[0108] In some embodiments, when the carton filling device can fold the laminate 120, can apply the first temperature T1 to the laminate 120, and already has the function of covering the packaging unit 110 with the laminate 120, there is no need for the above-mentioned "easily adjusting the carton filling device".

[0109] In other embodiments, the method of manufacturing the package 100 can be performed by a film wrapping machine that is easily adjusted without using a carton filling facility.

[0110] The above-mentioned simple adjustment to the film wrapping machine includes, for example, adding a stacking and filling mechanism (such as push rods or push plates).

[0111] Among these, the stacking and filling mechanism is used to stack the packaging units 110 up to the number covered by the laminate 120. Thereafter, the laminate 120 can be folded by a folding mechanism, and a heating element is applied to the laminate 120 at a first temperature T1 to form a package 100 including a desired number of packaging units 110.

[0112] In some embodiments, when the film packaging machine already has the functions of stacking the packaging units 110, folding the laminate 120, applying the first temperature T1 to the laminate 120, and covering the packaging units 110 with the laminate 120, there is no need to perform the simple adjustments on the film packaging machine as described above.

[0113] In some embodiments, as described above, the softening temperature T 122 of the plastic layer 122 of the laminate 120 is in the range of 50°C to 150°C, and the softening temperature T 111 of the plastic film 111 is in the range of 150°C to 200°C (for example, in the range of 155°C to 200°C).

[0114] For example, the plastic layer 122 of the laminate 120 contains polyethylene, and the plastic film 111 is a biaxially oriented polypropylene (BOPP) film.

[0115] Alternatively, for example, the plastic layer 122 of the laminate 120 may include high-density polyethylene (HDPE) and low-density polyethylene (LDPE), and the plastic film 111 may be a biaxially oriented polypropylene (BOPP) film.

[0116] In these embodiments, the range of the first temperature T1 may be in the range of 60°C to 150°C, for example, in the range of 100°C to 120°C. In this way, it has excellent processing speed under appropriate energy consumption.

[0117] In some embodiments, regardless of whether a carton filling device or a film wrapping machine is used to execute the manufacturing method of the package 100, in step S01, the laminate 120 can enter the carton filling device or the film wrapping machine in a single discontinuous form or a roll continuous form.

[0118] Further, in the present application, the package 100 can be formed by the manufacturing method of the package 100 using the various laminates 120 described above.
