BARRIER FILMS
Single layer films are generally quite permeable to most gases, making it not suitable to pack perishable goods. Over the years, technological advancement on machinery and resins has changed the packaging world completely with the advent of barrier film.

Great Wall Plastic Industries Berhad’s (GWPI) multi-layer co-extruded barrier film is ideal for food packaging, medical packaging and general packaging applications. Ours 5-layer blown film (exposed or buried nylon/EVOH) structures are engineered to meet the most demanding of customer’s specification. It contains chemical structures and barrier properties necessary to prevent permeability of oxygen, carbon dioxide, and nitrogen into packaging, enabling much longer shelf life.

Some salient features: -

• High Gas & Flavor Barrier
• Superior Mechanical Performance
• Thermal Resistance
• Thermoformability
