Oxygen Barrier Foil Bag

Oxygen barrier foil bag is a high-performance composite packaging product featured with ultra-low oxygen permeability,professionally developed to isolate external oxygen effectively.Adopting multi-layer aluminum foil laminated structure,it can drastically reduce oxygen penetration and cut off air oxidation reaction,which is widely applied in food preservation,healthcare products,chemical raw materials and oxygen-sensitive goods packaging industries all over the world.

The outstanding oxygen blocking capacity is its core competitive strength.The built-in dense pure aluminum foil layer forms a solid isolation barrier,achieving excellent low oxygen transmission rate far superior to ordinary plastic packaging and common aluminized bags.It can greatly slow down the infiltration of external oxygen into the sealed space,restrain aerobic bacteria reproduction and chemical oxidation reaction inside the package,so as to keep the intrinsic properties of packaged items intact for a long time.Most mainstream oxygen barrier foil bags adopt classic structures such as PET/AL/PE and NY/AL/CPP,with each layer cooperating closely to stabilize overall barrier performance without easy failure under normal storage and transportation conditions.

Apart from superior oxygen isolation effect,this packaging bag integrates multiple excellent auxiliary properties.It possesses full light-shielding function to avoid photochemical deterioration,and strong moisture-proof performance to block water vapor invasion.It also has good physical strength including high tensile resistance,puncture resistance and folding resistance,not easy to be broken or deformed during extrusion,stacking and long-distance delivery.The inner food-grade sealing layer ensures firm heat sealing without air leakage,locking low-oxygen sealed environment steadily inside the bag.

Oxygen is one of the main causes of commodity quality deterioration.Foods are prone to rancidity,discoloration,flavor loss and mildew due to oxygen contact;nutritional ingredients and medical supplies will lose efficacy rapidly under oxygen erosion;industrial raw materials and metal accessories are easy to be oxidized and rusted.Oxygen barrier foil bags perfectly solve these problems by building a low-oxygen sealed storage space,greatly extending shelf life and service cycle of various products.

It covers diversified application scenarios.In food industry,it is the ideal choice for vacuum cooked food,meat products,nuts,dried fruits,seafood,tea and fried snacks,effectively retaining original taste and freshness.In health care and pharmaceutical fields,it is used for packing health supplements,medicinal granules and various pharmaceutical intermediates to stabilize active ingredients.In industrial fields,it is widely used for packaging metal parts,precision electronic components,chemical powders and reactive raw materials to prevent oxidation deterioration and performance decline.

All qualified oxygen barrier foil bags are made of eco-friendly non-toxic raw materials,complying with international food contact safety standards.Various sizes,thicknesses and bag types including three-side seal,stand-up bag and vacuum bag can be customized.It is compatible with all kinds of automatic sealing and vacuum packaging equipment,convenient for large-scale industrial production and packaging operation.

As global merchants attach higher importance to product shelf life and quality maintenance,high barrier oxygen isolation packaging has become an inevitable trend.With reliable oxygen blocking effect,comprehensive protective performance and reasonable cost advantage,oxygen barrier foil bags have become core preferred packaging materials in high-standard sealed packaging fields,gaining wide recognition and stable market demand in international trade.
