Abstract
A high resistance composite packaging film for foods sequentially comprises a protective layer, an intermediate layer and a barrier layer, wherein the protective layer is a polyester film layer; the barrier layer is an EVOH (ethylene-vinyl alcohol) layer; the high resistance composite packaging film for foods is characterized in that the intermediate layer is a pure aluminum foil layer. Since pure aluminum foil is used in the intermediate layer of the high resistance composite packaging film for foods, the problems of low self intensity, high probability of tearing off, high probability of breakage during folding, eyelets generation and the like in aluminum foil can be solved; in addition, a polyester thin film is strong in spreading resistance, strong in material rigidity and high in hardness, and meanwhile can well adapt to external humiture and environmental conditions, has comprehensive water-blocking and air-resistant performances, is extremely low in air transmission coefficient, is oil and grease resistance, and can also can resist most of solvents and acidity and alkaline solvents.
Description
Technical field
The utility model relates to a kind of food composite package film, especially relates to a kind of high-barrier food composite package film.
Background technology
At present, be used for aseptic packaging, heat jar and retort pouch in grocery trade, the packing of packing dairy produce, meat, canned fruit juice and flavoring food all adopts composite package film.The barrier material of composite package film often is that protective layer, aluminium foil layer and barrier layer are formed; the material of barrier layer in the past is PVDC (polyvinylidene chloride), and its transparency, glossiness, mechanical strength, retractility, wearability, cold resistance and surface strength are all undesirable.It also is metal forming class unique in the composite package film packaging material that aluminium foil layer is arranged again; has the very long application time on the packing; it blocks water, choke, shading, etc. the obstruct protective value be that other any packaging material are difficult to be equal to; be the packaging material that still can not replace fully so far; has certain barriers function again simultaneously to oxygen and steam; and the ductility of general aluminium foil is not good, thickness is very low, very easily tear, easy fracture folding time the, weight per unit area are heavier, and it is undesirable easily to produce self performance defective protectiveness such as eyelet.
The utility model content
The technical problems to be solved in the utility model provides a kind of high-barrier food composite package film, and the aluminium foil ductility of solution normal food composite package film is not good, thickness is low, weight per unit area is heavier, the unfavorable problem of protectiveness.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high-barrier food composite package film, to form according to level by protective layer, intermediate layer and barrier layer, and described protective layer is the polyester rete; Barrier layer is EVOH (copolymer of an ethene and vinyl alcohol) layer, and it is characterized in that: described intermediate layer is the pure aluminum foil layer.
Described pure aluminum foil layer is obtained through calendering behind the electrolytic aluminium repeatedly, and optical density is between 0.15-0.50.
The thickness of described barrier layer is 50 μ m-70 μ m.
The thickness of described polyester rete is 12 μ m-16 μ m.
The beneficial effects of the utility model: use pure aluminum foil owing to adopt in the intermediate layer of high-barrier food composite package film, improved the intensity of aluminium foil own very low, be difficult for tearing, folding the time also easy fracture, produce eyelet, add polyester film itself and have very strong spreading resistance, its material stiffness is strong, the hardness height, and also possess simultaneously environmental aspects such as can adapting to outside humiture well also have comprehensive block water, gas barrier properties, air transmission coefficient is minimum, grease resistance and most solvent and Acidity of Aikalinity solvent.
