Description

Compositions for providing barrier properties for Paper, Cardboard and TextileFIELD OF THE INVENTION

[0001] The invention relates to compositions comprising a copolymer comprising styrene units and acrylic ester units and a styrene maleic anhydride copolymer, the manufacturing method and use of these compositions for providing barrier properties, like oil-barrier, liquid-barrier, and / or grease-barrier, and / or heat sealing properties to a substrate like paper, cardboard or textile.BACKGROUND OF THE INVENTION

[0002] Packaging has become an essential element in food purchases. The food is packed with the aim of being transported and stored. The packaging of food products is part of the marketing and distribution process.

[0003] The principal roles of food packaging are to protect food products from outside influences and damage. Plastics are the most common and most wide-ranging materials used for food packaging. Of the plastics used food packaging, polyolefins and polyester are the most common materials.

[0004] In recent years, as a result of a global environmental concern, plastic pollution has attracted worldwide attention. Plastic wastes not only disrupt ecosystems and biodiversity, but they also threaten human life and health. Therefore, packaging industry must move out to plastic packaging for more recyclable solution.

[0005] Following this trend, paper and paperboard packaging has become an alternative to this increasing demand of a sustainable and more environmentally friendly material and in this way the development of better solutions for a renewable, recyclable packaging.

[0006] Although paper and paperboard are an alternative to this demand of a more sustainable packaging materials, they don’t have the needed barrier properties to provide protection against water, grease, oil and other substances. Paper and paperboard havevery low barrier properties, as the material is very porous and thus having a high permeability. Paper and paperboard consist of cellulosic fibres, extracted from trees, combined with additives to make a continuous matted web, and thus forming the structure of the material. Paperboard is a relatively thicker and heavier material than paper. It is widely used as secondary packaging that is not generally in direct contact with the food. Its main use is for packaging and containers in the form of boxes.

[0007] To be a viable replacement, however, the barrier properties of paperboard need to be improved. The first step has been to develop paper and textile-based packaging using fibers treated with fluorochemicals. But fluorochemicals are now under pressure, as suspected to be persistent in the environment. There is still a need for a more sustainable solution than fluorochemicals. Polyethylene (PE) has also dominated as a barrier coating in packaging applications, due to its properties, especially to provide water resistance. However, packages coated with PE may be challenging to recycle at a standard recycling facility. Another concern is that PE coatings may contaminate fibers during the repulping process, prohibiting the fiber in this way from being recycled.

[0008] On the other side, for oil and grease resistance, early barrier coatings for food packaging were made from synthetic polymeric chemicals known as per- and polyfluoroalkyl substances (PFAS). PFAS are a diverse class of compounds characterized by having a hydrophobic, fluorine-saturated carbon chain joined to a hydrophilic functional group. This structure gives PFAS the ability to repel both water and fat readily. However, PFAS can’t be separated from the paper easily, which means the paper can’t be recycled or repulped. Besides this restriction, the whole family of compounds has also been shown to have harmful effects on human health.

[0009] Paper and Textile industries has been trying, without success until now, surface treatments using waxes, acrylic copolymers and mixtures of both; but these compositions are known to show weakness after folding and significant loss of their barriers properties. Low Tg acrylate copolymers have been tested in such applications, but their use is very limited today due to the stickiness and blocking problems created by the low Tg.

[0010] Today, on the market, there is still a need to find a replacement for plastic, a solution which keeping good barrier properties even after folding.OBJECTS OF THE INVENTION

[0221] In the following, the invention will be described in more detail, however, without being limited to the following specific embodiments.Test proceduresDetermination of liquid barrier properties according to TAPPI T441 Test Method (Cobb Test)

[0222] The liquid barrier properties are determined according to TAPPI T441 Standard Test Method (Cobb Test). The amount of liquid that can be absorbed by a given area of the sample after a specified time is measured.

[0223] The test sample paper is cut into pieces of 12.5 x 12.5 mm. This sample is pre-weighed on a balance and then placed inside the Cobb equipment when it is dry. Once the test sample paper is in place, a fixed amount of liquid (e.g. water, cola, oil or hot coffee) (100 ml (± 5 ml)) is poured into the cylindrical container. Simultaneously a timer is started. If not stated otherwise, after 60 sec, the remaining liquid is emptied. The test sample paper (wetted side up) is placed between two blotting papers resting on a plat rigid surface and the surplus liquid is removed by moving a hand roller once back and forth over the pad without exerting any additional pressure on the roller. Samples that show signs of leakage around the clamping area should be rejected. If any liquid has passed through the sheet to the rubber mat, the test is not acceptable. When this occurs, the time is shortened to 30s. The (wet) test sample is then weighed.

[0224] The Cobb value is calculated by the following equation:Cobb [g / m2] = (Wwet- Wdry) x 100

[0225] A high Cobb value indicates the ability of the substrate to easily absorb and retain moisture. A low Cobb value indicates the ability of the substrate to resist penetration and retention of moisture. Typical target Cobb values for the packaging industry are:- Water absorbency (around room temperature): < 20 g of absorbed water per m2,- Cola absorbency (around room temperature): < 20 g of absorbed water per m2,- Hot coffee absorbency (around 80°C): < 20 g of absorbed water per m2,- Oil absorbency (around room temperature): < 20 g of absorbed oil per m2.Determination of oil / grease barrier properties (according to Tappi T559 Standard Test Method)

[0226] The oil / grease resistance can also be determined according to Tappi standard T559 KIT Test. A value of 1 means bad / no oil / grease resistant properties, while a value of 12 means best / high oil grease resistant properties.Determination of blocking temperature

[0227] The blocking temperature is determined as follows: Two test specimen (25 mm * 297 mm) of the treated substrate are prepared and placed in a superimposed relationship to each other with the treated surface directed to each other in a HT-IXS Hot Tack Tester. Standard test is carried out with a 10 s dwell time and 1 bar pressure. Both jaws are heated, with the temperature variable. “Blocking temperature” is the highest temperature for which the apparatus measures no tack, i.e. no strength to the 2 strips.Determination of Heat Sealing Properties

[0228] The heat sealing properties are determined as follows: Two test specimen (25 mm * 297 mm) of the treated substrate are prepared and placed in a superimposed relationship to each other with the treated surface directed to each other in a HT-IXS Hot Tack Tester. Standard test is carried out with a 10 s dwell time and 2 bar pressure. Both jaws are heated, with the temperature variable. “Heat-seal temperature” correspond to the temperature which the apparatus measures a sufficient strength to seal both papers.

[0229] For the below reported tests a cardboard paper with a grammage of 250 g / m2, a coating of 8-9 g / m2 and a sealing area of 1 ,2 cm x 3,5 cm was used. Pull speed was set to 50 mm / sec. The heat sealing strength is reported in Newton and is the strength required to separate the test strips from each other, once they have sealed. The heat sealing strength is regarded as sufficient in case a value of > 3 N is achieved.Product stability tests

[0230] 100 g of the respective sample were stored in a glass flask (125 mL) at50 °C. Samples were checked every 24 h for visible phase separation. In a second stability test, the 100 g of the respective samples were filtered on a 150 pm nylon filter. The weight of the grits remaining on the filter was weighed and expressed in ppm inrelation to the total weight of the respective product. The results may be found in the below table 5General preparation procedure

[0231] 300 g of demineralized water are introduced in a reactor (reactor 1 ).Optionally, component (B2) is added and dissolved into the demineralized water with ammonium hydroxide. This mixture is then heated to 80°C. In case of Comp. Ex. 1 , 2 g of lauryl sulfate are added instead of component (B2). In case of Inv. Ex. 1 to 3 and 9 1 g lauryl sulfate are added together with component (B2).

[0232] In another reactor (reactor 2), lauryl sulfate (omitted in Inv. Ex. 5 and 7) is dissolved in demineralized water and then monomers (A1 ) and (A2) are added. This monomer mixture is stirred to be homogenized, and kept below 25°C.

[0233] In a third reactor (reactor 3), 1 g sodium persulfate is dissolved in 39 g of demineralized water. This solution is also kept at a temperature below 25°C.

[0234] When the internal temperature of reactor 1 reaches 80°C, the mixture contained in reactor 2 is dosed into the mixture of reactor 1 , while simultaneously, also the content of reactor 3 is dosed into reactor 2. Dosage takes place within 5 hours. At the end of the dosages, pumps are rinsed with 8 g of demineralized water. The internal temperature is maintained at 80 °C for 1 hour. The thus obtained copolymer dispersion is then cooled down to room temperature.

[0235] Table 1 lists the used compounds as well as their amounts.

[0236] The results of liquid resistance tests as well as heat-sealing properties, blocking temperature and stability can be found in Tables 2 and 3.Table 1 : Compositions of comparative and inventive examples for composition IComponent B2*#% means wt% based on the total weight of the aqueous composition#Component (B2): 25.0 to 35.0 wt% maleic anhydride and 65.0 to 75.0 wt% of styrene, wherein the wt% are based on the total weight of component (B2) (=100 wt%), esterified using ethanol, butanol, isobutanol or a mixture thereof, molecular weight in the range of 1 ,000 g / mol to 10,000 g / mol, a glass transition temperature of between 90 °C to 130 °C; wt% of SMA and alcohol in esterification the wt% is 80wt% to 90 wt%, respectively 10 to 20 wt%, wherein the wt% are based on the total amount of SMA and alcohol (=100wt%) used in the esterification reactionCoating procedure

[0237] All comparative compositions and inventive examples of composition I are applied using an Automatic Coater at 250 mm / s on white cardboard with a coat weight of5g / m2and dried at a temperature of 110°C using an IR lamp. The results achieved from the herein described tests, i.e. liquid-resistance, heat-sealing force and blocking temperature may be found for the comparative examples in Table 2. The results of the stability test can be found in Table 3.ResultsTable 2: Results of liquid resistance tests as well as heat-sealing properties, blocking temperatureTable 3: Results of the stability tests performedPreparation and determination of properties of Composition lie according to the inventionGeneral preparation procedure:

[0238] 300 g of demineralized water are introduced in a reactor (reactor 1 ).Optionally component (B1 ) is added and dissolved into the demineralized water with ammonium hydroxide. This mixture is then heated to 80°C. In case of Comp. Ex. 1 , 3 and 4, 2 g of lauryl sulfate are added instead of SMA. In case of Inv. Ex. 1 , 1 g lauryl sulfate are added together with SMA.

[0239] In another reactor (reactor 2) 10 g of lauryl sulfate (omitted in Inv. Ex. 6) are dissolved into demineralized water and then, at least the monomers (A1 ) and (A2) are added. This monomer mixture is stirred to be homogenized, and kept below 25°C.

[0240] In a third reactor (reactor 3), 1 g sodium persulfate is dissolved in 39 g demineralized water. This solution is also kept at a temperature of below 25°C.

[0241] When the internal temperature of reactor 1 , reaches 80°C, the mixture contained in reactor 2 is dosed into the mixture of reactor 1 , while simultaneously, also the content of reactor 3 is dosed into reactor 2. Dosage takes place within 5 hours. At the end of the dosages, pumps are rinsed with 8 g of demineralized water. The internal temperature is maintained at 80 °C for 1 hour. The thus obtained copolymer dispersion is then cooled down to room temperature.

[0242] At room temperature, the copolymer dispersion is then formulated with addition of component I. Table 4 lists all used compounds as well as their amounts.

[0243] The results of the liquid-, grease and oil-resistance tests as well as for the blocking temperatures can be found in Table 5 in case of the comparative examples and Table 6 in case of the inventive examples of compound He.Table 4a: Compositions of the comparative and the inventive examples of compound He.Table 4b: Continuation of table 4a.* % means wt% based on the total weight of the aqueous composition° Comp. Examples 1 , 3 and 4 are made with 2 g of lauryl sulfate, but no SMA. xlnv. Example 1 is made with 1 g lauryl sulfate added to reactor 1 together with SMA. inventive Example 6 is made without addition of any non-ionic or ionic surfactant. a Component (B1 ): 25.0 to 35.0 wt% maleic anhydride and 65.0 to 75.0 wt% of styrene, wherein the wt% are based on the total weight of component (B1 ) (=100 wt%); molecular weight in the range of 1 ,000 g / mol to 10,000 g / mol, a glass transition temperature of between 110°C to 150°CCoating procedure

[0244] All comparative compositions and inventive examples of composition He are applied using an Automatic Coater at 250 mm / s on office white paper with a coatweight of 5 g / m2and dried at a temperature of 110°C using an IR lamp, if not reported otherwise. The results achieved from the herein described tests, i.e. liquid-resistance, oil-resistance and blocking temperature may be found for the comparative examples in Table 5 and for the inventive examples in Table 6.General procedure for folding

[0245] All the resistances discussed in the following were measured before and after a subsequent folding process to obtain data on the foldability of the substrates treated with the compositions described in Table 4. Folding was performed on a large blotter with a 10 kg roller. The substrates were folded in half twice, once in the machine direction and once crosswise to the machine direction. Fig. 1 shows the blotter and roller as well as a result of the folding.Table 5: Results of the water- and oil-resistance tests and determined blocking temperature of the comparative examples.* respective result was determined before / after folding of the coated paper (g / m2)

[0246] In conclusion, low SMA proportions as in comparative examples 1 to 3 lead to undesirably sticky compositions, i.e. compositions blocking at low temperatures already, in combination with the styrene-acrylate copolymer. However, addition of SMA alone does not lead to satisfying compositions either since all resistances decrease after folding of the treated substrate and thus, are insufficient for finally shaped articles. Similarcan be observed for compositions based on acrylic copolymers as known in the prior art having deficiencies in the resistances after folding.

[0247] Further it is apparent from comparative examples 2, 3, 8 and 9 that the addition of an elastomer as e.g. natural latex may lead to an higher resistance to folding. However, the elastomer itself does not provide sufficient resistances.Table 6: Results of the water- and oil-resistance tests and determined blocking temperature of the inventive examples.* respective result determined either before(b) / after(a) folding of the coated paper (g / m2)

[0248] In comparison to the before discussed comparative examples, all inventive examples of composition He show low water uptakes in the Cobb test and high oil / grease resistance ratings in the KIT test. Further, blocking temperatures are sufficiently high tosatisfy industrial requirements. Additionally, the inventive examples of composition He show an improved resistance in said tests even after subsequent folding processes.

[0249] In summary, all inventive examples of composition He according to the invention provide good water- and oil / grease-resistances and further sufficiently high blocking temperatures and thus, solve the object of the present invention.Table 7: Results of the stability tests performed with all samples.

[0250] From the product stability test results depicted in Table 7, it can be clearly seen that components as waxes or high proportions of natural latex lead to stabilityissues. However, all inventive examples show satisfying storage properties at 50 °C and are thus, suitable products for coating applications.Preparation and determination of properties of Composition llw according to the inventionGeneral preparation procedure

[0251] 340 liters of demineralized water are introduced in a reactor (reactor 1 ). 80 to 110 kg of component (B1 ) (same as used in preparing composition He) in powder form is added. The temperature is increased to 40°C and 30 kg of ammonium hydroxide (aq.) are added. This mixture is then heated to 80°C. Demineralized water is added to adjust the concentration to 20%. 480 kg of the thus prepared mixture are used in the following.

[0252] In another reactor (reactor 2) the monomers (monomer A1 : 35 to 60 wt% of styrene, methyl methacrylate, and / or acrylonitrile; monomer A2: 40 to 65 wt% of 2 ethyl hexyl acrylate; wt% are based on total amount of monomers (=100 wt%)) are added (total amount 200 to 250 kg). This monomer mixture is stirred to be homogenized, and kept below 25°C.

[0253] In a third reactor (reactor 3), 2.2 kg ammonium persulfate is dissolved in 9 kg demineralized water. This solution is also kept at a temperature of below 25°C.

[0254] When the internal temperature of reactor 1 , reaches 80°C, the mixture contained in reactor 2 is dosed into the mixture of reactor 1 , while simultaneously, also the content of reactor 3 is dosed into reactor 2. Dosage takes place within 5 hours. At the end of the dosages, pumps are rinsed with 80 kg of demineralized water. The internal temperature is maintained at 80 °C for 1 hour. The thus obtained copolymer dispersion is then cooled down to 35°C.

[0255] Then 200 to 250 kg of soybean wax emulsion (solid content 40%) is added under stirring. The thus obtained composition llw is then allowed to cool down to room temperature.Coating procedure

[0256] The inventive composition llw is applied using an Automatic Coater at 250 mm / s on white card board with a coatweight between 0 to 14 g / m2and dried at a temperature of 110°C using an IR lamp, if not reported otherwise. The best results achieved from the herein described tests are shown in the following tables.ResultsTable 8: Oil-absorbency determined according to TAPPI T441 (Cobb-Test)Table 9: Determination of oil / grease resistance according to KIT Test
