This peelable forming film utilizes a proprietary peelable resin blend to provide seal integrity and easy peel opening to uncoated Tyvek. The coextruded film features the strength and formability of Surlyn combined with ULDPE to enhance toughness and flex resistance, while providing excellent film contact clarity. Coated webs are traditionally used to improve peelability and eliminate fiber tear when opening. However, contamination may still exist from particulates generated by the coating. Packaging utilizing the peelable Surlyn-based forming film addresses this concern, and offers a lower cost option compared to packaging using coated webs.
