Packaging film ImaflexellTM C01

barriermultilayerpolymer

Product Overview
The Imaflexell™ C01 is a five-layer freezing film featuring an EVA (Ethylene-Vinyl Acetate) contact layer and an LDPE outer layer. The EVA contact layer provides mechanical strength while retaining flexibility at low temperatures, resisting abrasion, puncture, stretching and tearing. The LDPE outer layer ensures transparency and additional flexibility. Together the layers preserve film integrity in cryogenic and cold-storage conditions, extending service life for temperature-sensitive products.

Applications
Single-sided EVA contact film designed for bioprocessing, pharmaceutical packaging and cryogenic storage. Suitable for freezing bags and containment of biologicals such as stem cells, blood products and reagents where moisture and oxygen barrier properties help maintain stability. Compatible with sterile manufacturing and cold-chain workflows.
