Description

Physicochemical Property:White fine grained,do not mix with toxic and harmfulmaterial.
Application :It is mainlyused for blown film. As food, medicine, military Cheese, soups, snacks, retort pouch, medical packaging, dry food packaging, biscuits and cereals, pet food, tensile membrane, sauces, meat products, up and down
Liquid packing, soy products, electronic products packaging, chemical packaging, etc. Resistant to **5℃/ *0 min cooking..
product description :PVDC, scientific name "polyvinylidene chloride", is a kind of softening temperature thermoplastic polymer in ******0℃, with its tail to a linear polymer chain structure. The molecular structure of symmetry, high crystallinity.
For PVDC, due to its strong cohesion of between molecules, high crystallinity, PVDC molecules of chlorine atoms in hydrophobicity, won\'t form hydrogen bonds, it is difficult to move in PVDC molecular oxygen molecules and water molecules,
To make it have excellent oxygen resistance and resistance to wet, and the resistance of oxygen is not influenced by ambient humidity. That is to say, at any temperature or humidity conditions, both excellent blocking water vapor and oxygen,
Smells and the ability of fragrance, is currently accepted the comprehensive performance of the best in terms of barrier property of plastic packaging materials.
Using resistance capability of PVDC, can delay the onset of food the oxidation phenomenon, greatly extend the shelf life of product, at the same time to avoid the built-in aroma loss and prevent the external invasion of bad smell;
Use its resistance to wet, can prevent the product water dry, the phenomenon of taste, will not damage packaging prototype by product water absorption, prevent natural depletion (gravity) in quantitative products.
Gas blocking performance changes over the humidity, even if the high humidity environment will not cause product deterioration; With its low permeability, can prevent the loss of fragrance, and do not absorb residual odor and abnormal flavor,
Can guarantee the integrity of odour (when packaging is low in fat or protein food this is especially important.
