What are the different kinds of plastic film?
• LdPE (Low density polyethylene): the most commonly used.
• Polyethylene variations:
- anti-uv: To protect film from U.V. ageing.
- Colour - opaque: product is not visible, colours are protected. (E.g.: for a coloured water: avoids colour change due to U.V.), etc.
• Non-stick and co-extruded PE+PP: to avoid the cover sticking to the product.
