At present, the composite paper package is a packaging product for liquid food, and the six-layer composite paper package consisting of paper, aluminum and plastic can effectively block air and light, so that milk and beverage can be more conveniently and safely consumed, the quality guarantee period is longer, and higher packaging efficiency is realized.

The composite paper bag finds a good balance point between the protection function and the satisfaction of emotional requirements. Compared with plastic bottles and glass bottles, brick-shaped and pillow-shaped composite paper bags have relatively large volume ratio, and the packaging shape is easier to pack, transport and store. If from the technical point of view, the composite paper bag is a six-layer composite paper package consisting of paper, aluminum and plastic, air and light can be effectively blocked, and the composite paper bag is just a killer which is easy to deteriorate milk and beverages. Therefore, the small composite paper bag enables consumption of milk and beverages to be more convenient and safer, has longer shelf life and realizes higher packaging efficiency. Cn201720753102.x a composite paper packaging and processing device cannot realize automatic production line type production.

Although the conventional liquid food packaging container, packaging material and filling method of CN201710866981.1 provide a filling method, in the actual production, after a bottle cap is installed, the problem of secondary pollution exists, secondary disinfection is required, so that pollution is easily caused, and the quality of liquid is affected.

In addition, due to the roof structure, the liquid in the container cannot be poured completely, and the space is wasted because the liquid cannot be arranged neatly when the liquid is conveyed or stacked. How to solve thereby the convenient pile up neatly of cancellation roof or transport and reduce extravagant, realize increasing the technical problem that bottleneck bore becomes the urgent need to solve equally.

Compared with the traditional structure, the invention reduces the upper folded lug, reduces the material consumption of composite paper, reduces the leakage caused by excessive contact surface, and reduces the exhaust emission, thereby greatly simplifying the process, being convenient to operate, eliminating the side clearance of the container during stacking, avoiding the defect of the traditional folded lug, breaking through the monopoly of foreign and international companies on the technology, having short time and high efficiency compared with the injection molding process, realizing the sealed bonding installation after filling, saving the cleaning process of injection molding residues, avoiding secondary pollution, avoiding the existence of the draft of a die, and avoiding the residue of injection molding taste. The injection molding process needs to prefabricate an opening at the bottom or the side of the container, so that a mold can conveniently enter the inner cavity of the container from the prefabricated opening, and a series of complex processes such as cooling, demolding, taking out the mold, and then carrying out disinfection and washing can be carried out. The cover of the invention has no pollution of chemical glue.
