COMPLETE CAST FILM PRODUCTION PLANT FOR WATER SOLUBLE PVA
COMPLETE CAST FILM PRODUCTION PLANT FOR WATER SOLUBLE PVA
Complete CAST FILM Production Plant for WATER SOLUBLE PVA FILM manufacturing in 1000 mm width x 400-450 Kg/Hr output .
The main raw material of PVA water-soluble film is polyvinyl alcohol. As a concept of environmentally friendly packaging material, PVA water-soluble film is widely used as inner packaging material for water-soluble chemical products in Europe, America, Japan and other countries. For example: pesticides, fertilizers, dyes, detergents, water treatment agents, mineral additives, detergents, concrete additives, chemical reagents for photography and chemical reagents for garden care, etc. It can also be used as rapeseed, plant seed bags, clothing packaging bags , Food and hospital washing bags and other products inside and outside packaging.
Advantages of water-soluble film
New type of environmental protection material, which degrades rapidly and dissolves in water immediately. The dissolved products are water and CO2, and no harmful substances are produced.
Simple and convenient to use, to avoid direct contact with harmful substances; oil-resistant, corrosion-resistant, and anti-static
It has good strength, toughness, plasticity, strong tensile resistance, bonding and heat-sealing performance.
Application scenarios: used for high-end textiles, plastic packaging bags, packaging cushions, and book/paper protective films.
Water-soluble packaging applications
Dye packaging Seed packaging Agricultural packaging Food packaging Chemical packaging Anti-sense ran packaging Textile packaging Anti-static packaging Cement additive packaging
