Description
Technical Field
The utility model relates to a wrapping bag, concretely relates to valve port wrapping bag.
Background
The existing paper packaging bag is mainly of an open structure, an opening is formed in the whole upper portion of a bag body, the structure is simple, the overall strength is low, the service life is short, and the paper packaging bag does not meet the actual use requirements. At present, a valve bag is one of bag types of a packaging bag in the packaging industry, can be quickly opened and is in butt joint with a material filling nozzle, and the material filling efficiency can be improved. However, in a fast packaging line, the sealing is difficult to be performed in a short time after filling, and the assembly line operation cannot be realized, which affects the production efficiency.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims at overcoming the not enough among the prior art, provide an anti tensile properties is good, and the heat-seal is fast, realizes that the filling seals the hot melt adhesive valve port bag of assembly line operation.
The technical scheme is as follows: in order to solve the technical problem, hot melt adhesive valve port bag, it includes the valve port bag body be equipped with the feeding cuff in the upper base of valve port bag body, the valve port bag body is formed by interior rete and the outer folding of paper the upper base of valve port bag body all is equipped with the enhancement layer in with going to the bottom, the feeding cuff is established on the enhancement layer in the upper base all be equipped with on the upper base and going to the bottom and connect the skin the outside is equipped with the hot melt adhesive circle that is more than or equal to 3cm wide in the outer port of feeding cuff.
The width of the hot melt rubber ring is 3 cm.
The feeding cuff is bonded and fixed in the upper bottom of the valve bag body.
The reinforcing layer is a kraft paper layer.
Has the advantages that: compared with the prior art, the utility model, it is showing the advantage and is: the utility model discloses overall structure sets up rationally, the valve pocket body is formed by interior rete and the outer folding of paper, whole stretch-proofing performance is good, all be equipped with the enhancement layer in the upper base of valve pocket body and going to the bottom, strengthen the stretch-proofing performance of folding department, it is more firm reliable to make overall structure simultaneously, adopt with valve pocket body integrated into one piece or the fashioned feeding cuff that bonds, make it be applicable to the valve port filling, all be equipped with on the upper base and going to the bottom and connect the skin, guarantee good sealed effect, the outer port inboard of feeding cuff is equipped with the wide hot melt adhesive circle of 3cm, through the hot melt adhesive melting device on the production line, can melt in 1-2s, seal fast, realize that the filling seals the assembly line operation, the wide hot melt adhesive circle of 3cm, can make to seal firm in connection reliable, accord with the in-.
