The soft tin was originated from 90 Times U.S.A., is the second innovation in the history of food packing, known as the second generation of tinned food. Its principle of processing and craft methods are put with the rigidity tin (glass, the iron cans) ,But because its packaging of windows are soft, so call it the soft tin. Because it is convenient that it is opened, quality guarantee period is long, non- apt to cause the bodily injury (glass . The iron sheet is apt to hurt one's feeling) Wait for the advantage, is welcomed in the developed country by consumers very much.

       The soft tin can be divided into on the whole ,Bag form( Commonly called as the high-temperature sterilization bag) . Cup form ( Commonly called as the high-temperature sterilization cup ). Bottle form ( Commonly called as the high-temperature sterilization pot ) Three kinds. The cup form is the technology that Japan develops ,Process and separate the compound panel multi-layer and high first ,And then press shaping through heating. Suitable for 500g-600g The following inner wrapping tin and garden stuff processing. Its characteristic is that volume is unrestricted in size that American-European technology takes bottle form as the core, type forms are diversified, it is the blank now that it is domestic to relatively popularize in America and Europe

Characteristic
         First. Can adopt at high temperature sterilizing, and time short, content thing nutrient destroy, pack soft compound membrane and tolerance of tin seldom 120 ¡æ The above-mentioned high temperature, and conduct heat fast, the cooling time after sterilizing is short, the time of whole sterilization is shortened by 1/2 than the rigidity tin, reduce the influence on looking for perfume in content greatly, especially nutrition loses the intensity and reduces greatly too, so has kept the already existing characteristic of the content thing.

         Two. Can preserve or circulate for a long time in normal atmospheric temperature, and person who keep steady soft tin temperature adjustment sterilization products packed to seal, so not need special save condition of refrigerating etc. under the normal atmospheric temperature condition, the ordinary warehouse, the shelve can be kept safely. The packing materials chemical property of soft tin is steady, will not the chemical reaction take place with the content thing, the metallic tank is apt to produce dense tin rotten candle and getting rusty, under the equal preservation condition, the tin is long than rigidity in the shelf life of soft tinned food.

         Three. It is convenient to carry, the soft tinned food is small and soft and easy to carry that open and save time simply safely, only tear from notch while employing, does not need special opening the pot tool, not as sharp as the tinplate or bits of broken glass Easy the danger that hurt one's feeling happen.

         Four. Save the energy, reduce and transport the cost, the soft tinned food is heated and eaten to only put and boil in the boiled water 15 Minute.
