7 Layer Blow VFFS Plastic Packaging Film
Product Description:
Coextruded film is a symmetrical seven-layer film, with excellent strength and puncture-resistance. Without biaxial stretch, coextruded PA film is superior in strength and puncture-resistance, compared with film with biaxial stretch. PA/PE is more cost-effective than asymmetric membrane, but not as flat in bag making. Blown PA/PE tube film can be made into bags directly with least cost.
Product Performance:
1. Highly puncture-resistant and flexible;
2. Highly transparent and excellent planeness of bags made by it;
3. Can be boiled and frozen, made into bags with tube film directly;
4. Thickness range: 30-300um.
