Atmosphere preservation packaging, also known as MAP or CAP, said the atmosphere tone packaging or replacement gas packaging, inflatable packaging, is the use of gas barrier properties of packaging materials packing food.According to the actual needs of customers will be a certain proportion of O2 + CO2 + N2, N2 + CO2, O2 + CO2 mixed fresh air to replace the air inside the box, making the bacteria dormancy or slow growth in this state of balance, to inhibit the growth of bacteria and microorganisms to achieve the purpose of food sensory, nutritional value of the mouth does not change , To prevent the food in the physical, chemical, biological and other aspects of the quality of the decline or slow down the rate of decline in quality, thereby extending the shelf life of food, to achieve the role of preservation, enhance food value. Compared to the traditional vacuum packaging, frozen packaging, additive shelf life, atmosphere packaging food does not allow physical or chemical reactions, no additives, to avoid secondary pollution.

Atmosphere packaging as a food packaging technology, has a long history, as early as the 1930s in Europe and the United States has begun to study the use of CO2 gas to save meat products, research and development in the 1950s, N2 and CO2 gas replacement canned beef and cheese cans. The air effectively extended the shelf life. In the 1960s, due to the development of a variety of airtight plastic packaging materials, many products such as meat products, fruits, vegetables, cakes, tea leaves and dairy products have successfully adopted the gas replacement packaging technology. 70 Since the inflated packaging of fresh meat in Europe and the United States is widely used, since the atmosphere in the world booming packaging development

Jinyu Tech mainly produces 11 layers of coextrusion high barrier cast film, 11 layers of co-extruded PA / EVOH / PE barrier film, 11 layers of coextrusion PA / PE medium barrier film, 11 layers of co-extruded PA / PP high temperature barrier film , PA / PE easily tear film, anti-fog film, and other types of functional multilayer co-extruded film.

11 layer co-extruded cast film, coextruded by a variety of materials, the performance of the advantages of a variety of raw materials collected, the different polarity of the resin modified polyolefin coextrusion bonding, including PE, PA, PP, EVOH variety of modified materials. Multi-layer co-extruded film to improve the oxygen and fragrance barrier, composite peel strength, environmental resistance and shelf life, but also achieved a variety of materials, a variety of advantages, with low overall cost, the appropriate secondary processing Replaced many of the dry-based composite packaging market, and no residual adhesive contamination. Eleven layers of co-extruded film most suitable for oxygen, moisture and strength requirements of food,, chemical raw materials, pharmaceutical products, cosmetic products packaging has become a new type of packaging in foreign countries trend.

1, high barrier and aroma-proof PA / EVOH co-extruded film has strong barrier air performance, anti-oxidation, waterproof, moisture-proof, good bang performance. In particular, the selection of EVOH as a barrier material, the oxygen transmission <10cc / m2.24h, water vapor transmission <10g / m2.24h

2, strong mechanical properties, anti-puncture, anti-breaking performance, outstanding tear resistance

3, PP high temperature (121 ℃), PE low temperature (-50 ℃)

4, oil, organic solvent-resistant, non-toxic and tasteless, in line with food, pharmaceutical packaging health standards

5, good heat sealing performance and cooking ability

6, soft, good transparency

7, printing compound adaptability
