Abstract

The invention relates to a milk machine aseptic packaging bag. The packaging bag is composed of an outer layer composite film and an inner layer PE film, wherein the outer layer composite film and theinner layer PE film are superposed, then the periphery of the outer layer composite film and the inner layer PE film are heat-sealed, and an air interlayer is formed between the outer layer compositefilm and the inner layer PE film. The formula of a first PE film, a second PE film and the inner layer PE film is optimally designed, the glue with good toughness is selected and used, after the produced outer composite film and the inner layer PE film are used for bagging, the heat sealing strength can reach 50N/15mm, after the bag is used for packaging 10 liters of liquid milk, the bag can resist positive pressure of 65kg and cannot break after dropping from a 1meter high place, and the defective rate is reduced from 0.1% to 0.05%.

Description

technical field [0001] The invention belongs to the field of packaging film materials, and in particular relates to a milk machine aseptic packaging bag and a production process thereof. Background technique [0002] Milk machines are widely used in hotels and guesthouses, and their storage and use are very convenient. In the future, they will be used in homes and vending machines. The milk machine is mainly composed of two parts: a functional case and a four-side-sealed double-layer film packaging bag filled with milk. This kind of packaging bag is also equipped with a filling port. The filling port is equipped with a cover with a sealed hose at the end. Cut off the sealing part of the hose before use. milk. At present, there are main problems in this type of milk filling packaging bag: the liquid flows in the packaging bag during transportation, which makes the packaging bag repeatedly deformed and wears and leaks; Contents of the invention [0003] In order to solve ...
