Description

Technical Field

[0001] The utility model belongs to the technical field of paper bags, and in particular relates to a high-efficiency filling composite paper bag. Background Art

[0002] A composite paper bag is a packaging bag made by laminating multiple material layers together. Common composite materials include paper, plastic film, aluminum foil, etc. Composite paper bags usually use paper as the main material to provide basic strength and protection. At the same time, by laminating other material layers on the paper, the function and performance of the bag can be additionally increased.

[0003] Compared with rigid packaging containers (such as plastic barrels, metal cans, etc.), the filling opening of composite paper bags is weaker in terms of self-support and stability. When filling is required, the insufficient rigidity of the paper bag may cause the filling opening to tilt or deform during the filling process. This causes trouble for manual fillers in some small businesses that do not have expensive filling equipment, and increases the difficulty and time consumption of filling. Therefore, we hope to design a composite paper bag with a new structure to solve this problem. Utility Model Content
