For PVDC, because of its strong intermolecular agglutination, high crystallinity, hydrophobicity of chlorine atoms in PVDC molecules, hydrogen bonds will not be formed, and it is difficult for oxygen and water molecules to move in PVDC molecules, so it has excellent oxygen and moisture resistance, and its oxygen resistance is not affected by the ambient humidity. In other words, under any temperature or humidity conditions, it has excellent barrier ability of water vapor, oxygen, odor and fragrance, and is currently recognized as the best plastic packaging material in terms of barrier performance.
The use of PVDC gas barrier can delay the occurrence of food oxidation and deterioration, greatly extend the shelf life of products, and avoid the loss of fragrance and the invasion of external bad smell;
By using its moisture resistance, the product can be prevented from drying and taste deterioration due to water loss, the packaging prototype will not be damaged due to water absorption, and the natural loss (weight loss) of quantitative products can be prevented. The gas barrier performance does not change with the change of humidity, and the product will not deteriorate even in high humidity environment;
Using its low permeability can prevent the loss of flavor, and does not absorb residual odor and abnormal taste, which can ensure the integrity of odor (especially when packaging low-fat or high protein food).
Excellent weather resistance, even if long-term exposure to the outside, direct sunlight, there will be no package fading and aging phenomenon.
Safety and environmental protection, in line with food hygiene requirements, through the FDA (U.S. Food and Drug Administration) certification, for food packaging safety escort.
