As long as they are handled well, there is no great impact on the shelf life of food.”sterile”packaging is in”sterile”In the natural environment, using instant high temperature and high pressure sterilization technology to sterilize packaged food, a form of packaging, commonly used composite materials are packaged through extrusion and composite molding in different forms. It has the advantages of being able to better preserve food, increase shelf life, save resources, reduce packaging costs, and easily complete plastic packaging. It is impossible to guarantee sterility in any food production and packaging process. The use of antibacterial polymer packaging products for food packaging can prevent bacterial pollution, increase the shelf life of food, and ensure food safety. Therefore, sterility will become the overall orientation of food packaging.Related article recommendation: What is used as a deoxidizer in food packaging bags?What is a sterile bag?Aseptic packaging is the process of preventing microorganisms from entering the packaging during and after packaging.Aseptic processing is a processing technique in which commercial heatSterilizedLiquid products (usuallyfoodorPharmaceuticals) are packaged under aseptic conditions into pre-sterilized containers to produce a shelf-stable product that does not require refrigeration.Aseptic packaging materials must ensure sterile conditions within the package, protect the product from physical damage, and maintain the quality of the product within the package.Aseptic processing consists of three main steps:heat sterilizationPackageSterilization of materialsSterility maintenance during packagingIn the food industry, aseptic packaging bags are divided intoLarge-capacity aluminum-plastic composite aseptic bag(5-20??0L) and small-capacity co-extruded film aseptic bags (200-500ml). They are the perfect packaging for juices, jams, dairy products and other foods.Aseptic packaging materialsseveral materialslayered together, to provide the level of protection required by aseptic packaging standards, including:polyethyleneUsed as a barrier inside and outside sterile packaging. these layersPrevent moisture from entering or leaving the container.film oilHelps preserve product by blocking light and oxygen.Aseptic bag application:Aseptic pouches are used for a variety of food products such as tomato concentrates, tomato pastes and pulps, fruit and vegetable juices, concentrates and diced fruits, as well as sauces, dairy products and liquid eggs. They are also used in the pharmaceutical industry to ensure that medicines are not contaminated with harmful bacteria. They are suitable for aseptically processed products that must be filled, stored and distributed at room temperature. They are a convenient and efficient way to transport large quantities of goods over long distances. Aseptic pouches are also suitable for efficient filling and dispensing of new, extended shelf life(ESL)of processed food and non-food products for better preservation.Advantages of sterile bags:extended shelf lifemaintain content qualityReduce packaging wasteReduce product wasteenergy efficiencyresource efficiencyAn economical solution for the packaging and shipping of high-volume liquid foodreduce shipping costsenvironmentally friendlyAbout aseptic bags(bag in box): KaryapolymerAseptic packaging (bag in box)Ideal for extending the shelf life of liquid or semi-liquid food or industrial products to store and transport liquid and processed products at room temperature without preservatives.KaryaPolymer aseptic packaging is made from multiple layers of metallized film of different materials; the number of layers and thickness varies by product. The strength of the pouch layer prevents air from entering the product and protects it from direct sunlight.Aseptic packagingProtect the product from the ingress of foreign matter. Therefore, the nutritional value, taste, flavor and color of the package contents will not change.feature:Extend the shelf life of food to 6monthReduce distribution and transportation costsMaintain product quality without preservativesAbility to sterilize products while packagingHigh temperature resistance.application:Tomato, vegetable and fruit concentrates.Juices, Distillates, Mineral Waters, Fountains, Syrups and MilkMilk powder, dough, pulp and puddingPharmaceutical raw materials
