EVOH Transparent High-Barrier Roll Film

Product information description:

7-layer EVOH co-extruded film   9-layer EVOH co-extruded film

EVOH transparent high-barrier roll film delivers outstanding oxygen barrier performance in a fully transparent, metal-free construction, making it the material of choice for applications where product visibility and high-level gas barrier must coexist. Multi-layer co-extruded structures with EVOH as the core barrier layer enable shelf-life performance comparable to foil laminates — the specific layer count and composition are specified based on the application's barrier requirements, mechanical demands, and budget.

The multi-layer co-extrusion process places the EVOH barrier layer between protective tie layers that maintain its barrier properties under conditions of humidity and mechanical stress. Outer and inner layers are selected to provide the surface quality, stiffness, and seal performance required by the specific application and filling equipment.

Higher layer count structures offer greater design flexibility, allowing precise tuning of barrier level, mechanical strength, and seal characteristics. Lower layer count structures provide a cost-effective solution for applications with moderate barrier requirements where transparency remains a priority.

This film is widely used for fresh meat, cheese, processed food, and medical device packaging where regulatory requirements or consumer preference prohibit the use of opaque or metallic materials. All structures are available in custom widths and can be supplied with surface treatments for print or lamination.
