Introduction About PVDC
Brief Introduction About PVDC The scientific name of PVDC is Polyvinylidene Chloride, the softening temperature is at 160℃ — 200℃, the density of PVDC film is 1.6 — 1.7g/cm ³. ØPVDC molecular chain has the characteristic of regularity, high symmetrical structure, polarity and easy to form hydrogen group. High degree of crystallinity, small grain size, no hydrophilic groups, outstanding barrier properties. PVDC was invented in the 1930s and used for military supplies in the early time. Now it is applied to food, medicine, chemicals and electronics packaging because of its excellent barrier properties. The reason for selecting PVDC as barrier layer Excellent barrier properties: PVDC has excellent properties for oxygen barrier, gas barrier, moisture barrier, and taste holding. It is widely recognized as the best flexible packaging materials with good barrier properties. The stable barrier properties: no influence to the PVDC barrier properties with the ambient temperature and humidity changes. Excellent weather resistance: anti-aging ability. Safe and environment-friendly, FDA approves to contact with food. Reliable quality, safety are provided for your products with PVDC packaging. The environment-friendly performance of PVDC PVDC products in the United States is determined to be non-toxic and safe plastic material, it is used in food packaging...
