What is cling film made of?
Cling film is primarily made from polymers like polyethylene (LDPE) or polyvinyl chloride (PVC), sometimes polyvinylidene chloride (PVDC), derived from petroleum or natural gas, with additives for stickiness. Modern, food-safe versions often use LDPE, while older or certain brands might use PVC or PVDC.
Key Materials & Types:
1.Polyethylene (LDPE/LLDPE): A common, cheaper, and generally safer alternative, but less sticky; often blended with Linear Low-Density
2.Polyethylene (LLDPE) for strength and cling.
3.Polyvinyl Chloride (PVC): Used historically and globally, offering great cling due to low permeability to oxygen and water, but raises concerns about plasticizer transfer.
4.Polyvinylidene Chloride (PVDC): The original material for Saran Wrap, known for excellent cling, but now less common due to environmental/health concerns.
