Description
Technical field
The present invention relates to a kind of food plastic composite packaging film, particularly relate to the composite package film of the anti-boiling of a kind of stretch-proof high-barrier.
Background technology
At present, food and medicine composite package film that domestic consumption is maximum all adopt common BOPP film (Biaxially oriented polypropylene plastic sheeting) and PP film (polypropylene blown film) to be composited.This composite package film is subjected to the welcome of packaging industry deeply because low price is easy to make.
But, because BOPP film and PP film itself exist the gas permeability and the water penetration of trace,, very big hidden danger is arranged for depositing long food and medicine of shelf time, make food or medicine receive the erosion of mould and microorganism easily.For gas permeability and the water penetration that reduces film, prior art is taked the low PP film of cost is replaced with high-grade gas permeability, the vacuum plated aluminum film that water penetration is extremely low usually, with BOPP film a kind of packaging film that is composited.But the vacuum plated aluminum film cost is very high, causes the packing cost of product to increase.
Because the product of the similar packaged form of current use, the shelf-life is all lower, generally is no more than 90 days, otherwise can cause bacterial reproduction in the food pack, cause food spoilage, spoiled, directly influence the healthy of consumer.
At present, also have much about the patent documentation of food package film report, for example: 1, application number is 200910101322.4, denomination of invention is the patent of invention of " antibacterial BOPP/PP food composite package film and preparation method thereof ".2, application number is 200510002129.7, denomination of invention is the patent of invention of " a kind of high-block degradable membrane and manufacturing approach thereof ".3, application number is 03126114.0, denomination of invention is the patent of invention of " PVDC lamination complex fire resistant cooking food packaging film and preparation method thereof ".
