Ethypel Performance CP 63 gsm is a medical cellulose-based overall coated top web solution designed to provide a superior and consistent sealing performance when combined to non-formable PET/PE films.
Ethypel Performance CP 63 gsm is made of a 60 gsm cohesive base sheeting coated with a water-based 3 gsm adhesive layer providing a strong sealing performance through high reactivity while ensuring an excellent aseptic opening including a soft peeling effect. This top web solution made of more than 90% of renewable resources also ensures a better environmental performance.

Bottom Web:

Ethyflex HSTP 52 μm is a 2-layer laminated PET/PE film specifically designed to provide superior run-ability on fastest packaging lines (rotary and platen sealing equipment) thanks to an optimized heat-seal layer. When combined to Sterimed top web solutions, Ethyflex HSTP 52 μm is able to provide a consistent sealing performance on a large operating window. 


Gloves, gauzes and active woun dcare of all shapes and

Package Performances:

The Ethypel Performance CP 63 gsm + Ethyflex HSTP 52 μm solution is especially adapted to wound care packaging (all sizes and all shapes) requiring high productivity level on rotary and platen sealing equipment. This material combination offers a consistent seal strength performance, between 1.9 and 2.3 N/15mm, when processed on recommended operating window* while ensuring an excellent aseptic opening including a soft peeling effect.
