Definitions
- the present invention relates to a food packaging multilayer film for packaging food.
- the multilayer film of the present invention is useful for packaging foods such as cheese, sausage, and fish, and particularly for packaging sausages.
- Nylon has the advantage of good adhesion to sausage and other foods, low oxygen permeability, and good printability, but because of its high water vapor permeability, it can be used for long-term storage, such as sausage. There was a drawback that the food lost its moisture and the surface became hard and freshness was lost.
- the color when a pigment is blended in a nylon casing, for example, when the sausage is boiled, the color may be transferred to the sausage or external boiling water.
- An object of the present invention is to provide a multi-layer film for food packaging having excellent oxygen barrier properties, low water vapor permeability and low color transfer to foods, and high food concealment properties.
- the present invention provides the following multilayer film for food packaging.
- a multilayer film for food packaging comprising an intermediate layer comprising a polyamide and a batch of a polyolefin-based mass blended with an inner layer containing a polyamide and an outer layer containing a polyamide.
- Item 2 The film according to Item 1, wherein the intermediate layer further contains a binder.
- Item 3 The film according to Item 1, further comprising a blocking inhibitor in the inner layer.
- Item 4 The film according to Item 1, wherein the polyolefin-based masterbatch is a modified polyolefin-based mass batch.
- a package comprising a multilayer film according to any one of Items 1 to 4.
- the polyamide blended in the inner layer, the outer layer, and the intermediate layer includes nylon 6, nylon 66, nylon 61, nylon 11, nylon 12, MXD nylon (polymethaxylylene adipamide) and These copolymers are exemplified.
- the polyamide blended in the inner layer, the outer layer and the intermediate layer may be the same or different.
- One polyolefin-based master batch is prepared by pre-dispersing a coloring material, for example, an organic or inorganic pigment or dye in polyolefin.
- a coloring material for example, an organic or inorganic pigment or dye in polyolefin.
- the ratio of the pigment or dye in the polyolefin masterbatch is not particularly limited, but is preferably about 5 to 70% by weight.
- polyolefins include homopolymers of olefins, mutual copolymers, copolymers with other copolymerizable monomers such as other vinyl monomers, and modified polymers thereof.
- polyethylene LDPE, LLDPE, etc.
- polypropylene polybutene
- their mutual copolymers ionomer resins
- ethylene-acrylic acid copolymers ethylene-vinyl acetate copolymers
- modified polyolefin-based resins Etc. can be exemplified.
- the modified polyolefin resin may be copolymerized with an unsaturated carboxylic acid such as maleic acid or fumaric acid or a derivative thereof such as an acid anhydride, ester or metal salt, for example, in the homopolymer or copolymer of the above-mentioned olefins.
- a modified polymer obtained by graft copolymerization can be exemplified as a typical example, and includes a modified polymer alone or a mixture with another component, for example, another polyolefin resin.
- Particularly preferred polyolefin resins are low-density polyethylene, linear low-density polyethylene, ionomer resins, maleic acid-modified polyolefin resins, ethylene-biel acetate copolymers, and the like.
- Organic colorants or pigments include azo pigments (soluble azo, insoluble azo (monoazo, disazo), condensed azo, metal complex azo, benzimidazolone) and polycyclic ( Phthalocyanine, anthraquinone, indigo, perinone, perylene, quinophthalone, dioxazine, quinacridone, isoly Organic pigments such as undrinone, metal complex, methine'azomethine, and diketopyropyrrole, water-soluble dyes (basic, acidic), and oil-soluble dyes (azo, anthraquinone, perylene, etc.) Is exemplified.
- azo pigments soluble azo, insoluble azo (monoazo, disazo), condensed azo, metal complex azo, benzimidazolone
- polycyclic Phthalocyanine, anthraquinone, indigo, perinone, perylene, quinophthalone, diox
- inorganic pigments examples include metal oxides (titanium oxide, iron oxide, composite oxides, etc.), chromates, sulfides, silicates, and carbonates.
- the intermediate layer preferably contains a binder.
- the binder is not particularly limited as long as it improves the compatibility between nylon and the master batch, and examples thereof include a maleic acid-modified polyolefin resin.
- the preferred blending ratio of each component of the intermediate layer is polyamide 40 to 95% by weight, preferably 50 to 95% by weight; master batch 2 to 20% by weight (2 to 70% by weight as a coloring material). %, Preferably about 5 to 70% by weight); the binder is about 3 to 58% by weight, preferably about 3 to 40% by weight. If the amount of polyamide in the intermediate layer is too small, the adhesiveness to the outer layer and the inner layer will be reduced, and if the amount of polyamide is too large, the compatibility with one master batch will be reduced.
- An anti-blocking agent can be added to the inner layer as needed.
- the antiblocking agent include silica and starch.
- the antiblocking agent may be kneaded into the inner layer polyamide or may adhere to the surface of the inner layer.
- the amount of the blocking inhibitor to be used is about 0.1 to 4% by weight, preferably about 1.5 to 3% by weight, based on the amount of the polyamide when it is previously incorporated into the inner layer.
- Examples of the packaged foods to be covered by the multilayer film for packaging of the present invention include processed meat products such as ham, sausage and bacon, processed fish meat, battered products such as potato mapoco and chiku, and milk products such as cheese. it can.
- examples of the form of the multilayer film for packaging include a casing and a bag-like material. Seamless as a multilayer plastic film If a tube is used, it may be cut into appropriate lengths and used as it is as a casing, bag, or the like.If a flat film is used, an appropriate form of packaging material may be used by a conventional method. Good.
- the multilayer film for packaging of the present invention is preferably a heat-shrinkable film stretched 1 to 5 times in the machine direction (MD) and 1 to 5 times in the transverse direction (TD).
- the preferred thickness of the multilayer film of the present invention is 3 to 20 zm for the inner layer, 3 to 20 m for the outer layer, 10 to 30 mm for the intermediate layer, and 16 to 50 m as a whole, preferably 30 to 50 m.
- the oxygen transmission rate and water vapor transmission rate are low, there is little transfer of the color to food, and the multilayer film for food packaging excellent in concealment ⁇ fe is obtained.
