Production technology
We adopts the PVDC technology held by SK Zhixin, which is a mature industrial technology that SK Zhixin continuously conducts PVDC research and development on the basis of the acquisition of Dow Chemical's PVDC factory in the United States. The technology is a global leader with a high degree of automation, and can produce two types of high-end barrier products, PVD-MA and PVD-VC. It can meet the needs of customers in various fields
Product features:
Polyvinylidene chloride (PVDC) is a copolymer of vinylidene chloride (VDC) monomer as the main component, non-toxic, tasteless, green environmental protection. The high crystallinity and high density of PVDC determine that PVDC copolymers have excellent high barrier properties to water vapor and other gases, and PVDC has excellent properties such as preservation, fragrance preservation, corrosion resistance and heat resistance.
(1) Excellent barrier property
(2) Longer shelf life
(3) Excellent cooking resistance
(4) Excellent resistance to chemical media
(5) Excellent fire resistance
(6) Excellent tear resistance
(7) Good processability
(8) Environmental protection of packaging materials
The properties of VDC copolymers vary with different comonomers. According to the requirements of different users, various products such as PVDC-MA and PVDC-VC for multiple uses can be produced.

PVDC is an extremely excellent packaging material, widely used in the barrier packaging field of food, medicine and cosmetics. Due to its dual properties of oxygen and water barrier, it has an incomparable advantage in the packaging application of meat products.
In the field of frozen food packaging, it can be used for refrigerator storage cling film, packaging bags for frozen foods, etc.
(2) In the field of high-temperature cooking packaging, it can be used for casing films for high-temperature sterilization and microwave heating preservation films, etc.
(3) In the field of cold fresh food packaging, it can be used for shrink films and shrink bags for cold fresh meat packaging, etc.
(4) In the field of low-temperature product packaging, it can be used for multi-layer co-extruded films and other packaging materials suitable for traditional low-temperature products.
(5) In other food packaging fields, due to its excellent barrier properties, it can delay the deterioration of food.
It is widely used in the packaging fields of sausages, cheese, soups, snacks, dry food packaging, biscuits and cereal foods, pet foods, etc. to prevent deterioration, extend the shelf life of products and prevent the deterioration of food taste.
In the field of pharmaceutical packaging, PVDC pharmaceutical packaging has excellent barrier properties against water, light, and odors. Its stability in blocking water vapor and oxygen is good, which greatly extends the shelf life
