Background
The composite flexible packaging material can be used only after being made into various packaging bags. The bag making has two modes, one mode is that a packaging manufacturer adopts a roll film to fill on an automatic packaging machine and forms and packages the roll film into various packaging bags; another is because the bag making machine makes various kinds of packaging bags and then fills the contents. Because professional bag making control is accurate, the bag shape is attractive, bag making change is large, and the bags are multiple, the bags are made in advance under quite many conditions. The main varieties of bags are: three-sided bags (palm-folded bags), back-folded bags, stand-up bags, and the like. The back sealing bag, also called the middle sealing bag, is a special vocabulary in the packaging industry, and is a packaging bag which is simply subjected to edge sealing and edge folding in the middle of the back surface of a bag body. Compared with other packaging forms, the back sealing bag has the advantages that the two sides of the bag body are not sealed, so that the front pattern of the packaging bag is complete and attractive, meanwhile, the bag body pattern can be designed into a whole in typesetting design, and the picture continuity can be kept. The back sealing bag is manufactured and packaged with difficulty in heat sealing the T-shaped opening, the T-shaped opening can not be well heat sealed generally, in the process of filling or transporting materials, the materials are contacted with the T-shaped sealing opening to generate impact force, or the back sealing bag is extruded by external force to expand the T-shaped opening, the bad conditions such as air leakage and even bag breakage are easily caused, the sealing property is influenced, and when patterns are required to be printed on the back of the back sealing bag, particularly the patterns in a string of characters/letters, the edge sealing of the folded edge can cause the patterns to be disconnected, and the appearance is influenced.
The utility model relates to a portable back of body envelope of high leakproofness is in order to solve the problem that exists among the prior art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a portable back of body envelope of high leakproofness to solve the problem that proposes among the above-mentioned background art.

Through the technical scheme, the secondary sealing of the back sealing bag after heat sealing is realized, the situation that the heat sealing edge is propped open to cause the material to leak and flow out due to the fact that the material directly impacts the heat sealing edge in the filling and transportation process of the back sealing bag is avoided, the sealing structure of the back sealing bag is reinforced, the sealing property and the practicability of the back sealing bag are further improved, the heat sealing edge is firmly attached to the back of the back sealing bag through the adhesive, and the smooth bag surface is more favorable for continuously printing characters and patterns.
Preferably, the adhesive can be arranged on either left side or right side of the back sealing bag body.
Through the technical scheme, the adaptability adjustment is carried out on one side where the viscose is located according to the pattern layout needing to be printed on the back envelope in the production process.
Preferably, the inner wall of the back sealing bag main body is provided with a polyethylene coating.
Through the technical scheme, gaps possibly existing after hot melting edge sealing are filled, and the sealing performance of the back sealing bag is further improved.
Preferably, the top of the back envelope main body is provided with a handle hole.
Through the technical scheme, people can conveniently and better move and carry the back envelope, and convenience is improved.
Preferably, the top edge of the back cover bag main body is provided with a notch.
Through the technical scheme, people can tear and detach the back sealing bag better conveniently, and the fragments of the torn back sealing bag are complete and convenient to collect.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the portable back sealing bag with high sealing performance is provided with the adhesive, the T-shaped heat sealing edge of the back sealing bag is attached to the front cover on any side of the back surface of the back sealing bag through the adhesive, the sealing performance of the T-shaped heat sealing edge is improved, materials inside the back sealing bag are prevented from impacting the inner surface of the back sealing bag and the T-shaped heat sealing strip during filling or transportation, the T-shaped heat sealing strip of the back sealing bag is spread, and accordingly the situation that broken materials of the back sealing bag leak out is caused;
2. this portable back of body envelope of high leakproofness is provided with the polyethylene coating film, can fill the clearance that back of body envelope heat-seal edge exists, prevents that the back of body envelope from taking place to leak gas and expand the package, has also avoided the outer air of bag and bacterium to get into in the bag, leads to the interior material of bag to take place rotten condition, has improved the leakproofness of back of body envelope.
