Multi-layered thermoplastic film with improved oxygen permeability |
| 摘要 |
A multilayer film characterized by having excellent oxygen permeability and thermoformable properties comprising a sealant layer and a heat resistant layer is disclosed. The sealant layer contains an ethylene based polymer or copolymer. The heat resistant layer has a melting point greater than that of the polymeric composition of the sealing layer. Internal layers may also be provided. |
