High barrier film like EVOH packaging film is a multilayer film made with barrier material to decrease gas or moisture permeability.
High barrier film is the most frequently used for food packaging and pharmaceutical products. Due to multi-layer structure including polymers as EVOH or PA9 polyamide ) which are barrier materials, it can prevent the transmission of oxygen, water vapour, moisture and/or aroma through the packaging film and protect the packaged goods from quality deterioration.
EVOH packaging film provides very good gas barrier properties including oxygen barrier, carbon dioxide barrier. EVOH film is also strong, flexible and transparent. EVOH film, due to its high barrier properties, helps to keep gas mixtures inside the package ( modified atmosphere packaging or MAP). Polyamide films ( PA ) have also a good protective effect against oxygen and carbon dioxide, a high thermo stability and a very good thermo form ability. Combined with PE, PA films provides a good vapour barrier. With pharmaceutical products, some barrier films have a sterilization effect, and keep out contamination with germs. The range of high barrier films we offer have PE, PP and/or PS base combined with EVOH or PA. All these barrier films can be use with different process of lamination like glue, heat lamination, calendaring, IML, lining, wrapping /thermoforming
These high barrier films can also be made peel able.
