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.
