In recent years the experiment considers to make clear, with can not make PVDC film without solvent compound method allow to manage where and undertake directly compound make compound film. This kind of compound film won't be destroyed in the configuration of whole film when high temperature evaporate is boiled, maintain level from beginning to end smooth, union is close together, blending an organic whole, evaporate of OK and complete contented high temperature boils the need that food packs. The PVDC lamination that makes with this method is compound high temperature resistant after evaporate boils food to pack film to put in the market, got the expert's affirmation, proving its is afterwards aluminium model is had at the same time after compound film tall cut off transparently, high, high temperature resistant the food that evaporate cooks 3 big character packs film, function index achieved international advanced level.

PVDC lamination is compound compound film photograph compares film and aluminous model cut off the gender is adjacent, completely transparent, more soft, use at skin package of fleshy food vacuum, the air in bag is smoked very neatly, more benefit lasts at what carnivorous tastes, and but microwave heats, and the price is equivalent to aluminum foil only the 70%~80% of compound film, because this can be inside quite big range,replace aluminous model compound film application.

Current, polyvinyl alcohol (PVA) kind the research development that besmears the block of Fu BOPP shows sexual film, more food is packed bring new hope. This kind cuts off film holds the block that provide oxygen concurrently to appear gender and vapor block to appear a gender, poisonous element is not contained in polymer, toxic element won't happen to change an appearance in use process, cut off material PVA is material of microbial synthesis high polymer, have hydrolysis and biology degradation double degradation mechanism, but complete degradation is water and carbon dioxide, it is a kind of high-powered environment more friendly profile makings, film of PVDC besmear Fu can be replaced in a lot of respects. It basically is used at the flesh kind food, quick-freeze is convenient feed what category and blame feed category to protect sweet model (be like insect-resistant agent) those who wait pack, having wide applied perspective.
