Recently, are popular among a heat shrinkable film labels on consumer goods packaging, PVC film market share is very large.
co-extrusion film
co-extrusion film is packaging film industry * new technology trends.
The film USES the ordinary ink and coating, high barrier property, good transparency, heat sealing and typography of flexibility, can be used as a plasma coating material.
Co-extrusion packaging film development will change the products structure of multi-functional films, suitable for drinks, milk, fresh meat and other food packaging.
Co-extrusion packaging film in developed countries accounted for about 40% of all soft plastic packaging film, while China accounts for only about 6%.
edible film
