The aluminum foil film for sealing small pots of tea usually consists of two or three layers of materials. Small cans of tea-sealed aluminum foil paper can be produced and processed according to different data layouts (such as OPP, CPP, PE, PET, PP, PVC, electroplated aluminum foil, pure aluminum foil, coated paper, etc.). ) and different standards of aluminum foil sealing film. Aluminized active packaging film can be used for packaging food, cosmetics, medicines, etc. , which increases the air tightness of the goods, reduces the moisture-proof probability of the goods, and makes the fragrance and fresh-keeping period of the small pot of tea last longer.
Manufacture of aluminum foil film for small pot tea sealing: after hot rolling and cold rolling, the thickness of aluminum plate blank exceeds 0.3 mm, which is called aluminum plate; If the thickness is less than 0.3 mm, it is called aluminum foil and then made into aluminum foil sealing film. Aluminum foil is usually made of 1 or 2 industrial aluminum. Aluminum foil has all the characteristics of metallic aluminum. Thermal conductivity, air tightness, light shielding and electromagnetic radiation shielding are all very important qualities.
First of all, it mainly uses a special equipment for sealing small pots of tea with aluminum foil film on the market. It uses electromagnetic principle. By generating magnetic lines of force and relying on the heat energy generated in the cutting process, the sealing layer of aluminum foil gasket and the bottle mouth of small pot of tea aluminum have certain physical changes, and their molecules can penetrate each other, thus achieving the sealing effect. Its excellent sealing effect has been widely used in small pot of tea, food, medicine and other fields, and it is an ideal sealing solution at present.
Of course, it is impossible for people to complete this task, and if they stick it with glue, it will not only be unsanitary, but also increase the difficulty for consumers to open it. Using aluminum foil gasket not only achieves ideal sealing effect, but also does not increase the difficulty of opening.
