1、 Name
PVDC is recognized as the best comprehensive barrier performance of plastic packaging materials. According to the requirements of use, two or more layers of different packaging materials are bonded together by adhesive by using the high barrier property of PVDC and combining the characteristics of different packaging materials, so as to obtain the packaging film with ideal comprehensive performance
2、 Performance
1. The oxygen permeability is low, less than 30cm3 / m2.24h.atm, which can effectively prevent oxidation deterioration of food. According to different products, the shelf life can be up to one year, and it can also keep the fragrance of the contents and prevent the invasion of external bad smell.
2. The water vapor transmission rate is low, less than 5g / m2.24h, which can effectively prevent water loss, and will not make the product dry and taste worse.
3. The inner layer printing can be realized to improve the printing and packaging effect.
4. It can be sterilized at high temperature, and can withstand the high temperature of 130 ℃, which can meet the sterilization needs of packaging high temperature meat products.
5. The low temperature resistance is general, and the lowest temperature resistance is - 8 ℃.
6. Excellent weather resistance.
7. PVDC substrate can only be used as intermediate layer, the outer layer is used as printing material BOPP, pet and PA, and the inner layer is used as heat sealing material CPP and PE.
8. In wet conditions, the barrier of the package does not decline, and it still has a good protection effect on the product.
9. Automatic continuous production can be carried out to improve labor efficiency.
10. It can be used as tensile film with the maximum tensile depth of 40mm.
11. It has the advantages of low cost and low price.
12. Non toxic, tasteless, safe and reliable.
13. It meets the food hygiene requirements of FDA.
