Abstract
The invention discloses a kind of packaging bags, are made of outer layer and inner plastic, and outer layer forms the outer bottom of packaging bag by sewer of sewing, it is characterized in that, it is provided with boiling hot trace line on the position close to sewing thread, this scalds trace line and fuses together outer layer and inner plastic, forms the interior bottom of packaging bag.Outer layer and inner plastic are sewed together by the sewing thread.The outer layer is combined by packaging paper layer and braiding layer, wherein packaging paper layer is located at outermost layer.The braiding layer forms sack on the position of packing bag mouth with inner plastic by the way that bonding agent is be bonded.The braiding layer is be bonded by bonding agent in the other positions of packaging bag with inner plastic.Further include outer lining, which is wrapped in the outer bottom of packaging bag, and outer lining, outer layer and inner plastic are sewed together by the sewing thread.The outer lining is made of paper or plastic foil.The present invention has reasonable for structure, high-quality, yield height, the advantageous effect of simple production process.
Description
Technical field
The present invention relates to a kind of packaging bags.
Background technology
Packaging bag has monolayer package bag and multi-layer packaging bag, can be ventilating packaging bag and Air Proof Packing pack, according to object
Product difference can select different types, have a kind of common packaging bag as depicted in figs. 1 and 2 on the market at present, by 2 He of outer layer
Inner plastic 3 is made, and outer layer 2 is combined by packaging paper layer and braiding layer, and outer layer 2 forms packaging bag by the sewing of sewing thread 11
Outer bottom, as shown in Figure 1, together with outer layer 2 is made sewing thread 11 with inner plastic 3, the outer layer 2 of sack will be moulded to in-flanges
Material internal layer 3 wrap up with sack line 12 sew, the packaging bag due to inner plastic 3 have sewing hole can gas leakage, as shown in Fig. 2,
Inner plastic 3 scalds into bag baseline 31 in advance, then bag bottom is packed into, and finally, outer layer 2 is sewn into together by sewing thread 11, the packet
When it is relatively good to pack sealing performance, but inner plastic 3 being inserted into outer layer 2, processing technology is more complicated, and the bottom of inner plastic 3
With the bottom location dislocation of outer layer 2, when filling article, the bottom of inner plastic 3 can be elongated, it is possible to can be pulled open.
Invention content
The present invention can obviously simplify processing technology according to the above deficiency, provide a kind of packaging bag, simplification process equipment,
Ensure that packaging bag is air tight simultaneously.
The technical scheme is that：
A kind of packaging bag, is made of outer layer and inner plastic, and outer layer forms the outer bottom of packaging bag by sewer of sewing, close
Boiling hot trace line is provided on the position of sewing thread, this scalds trace line and fuses together outer layer and inner plastic, forms the interior of packaging bag
Bottom.
It scalds trace line to extrude by high temperature, it is clear that fuse together not only air tight by outer layer and inner plastic but also can increase strong
Degree, is significantly improved than existing packaging bag.
Preferably, outer layer and inner plastic are sewed together by the sewing thread.The technical solution forms Double bottom, than
Existing packaging bag is more together to be insured.
Preferably, the outer layer is combined by packaging paper layer and braiding layer, wherein packaging paper layer is located at outermost layer.
Packaging paper layer can print different patterns, and color is relatively abundanter, and the intensity of braiding layer is got well than paper.
Preferably, the braiding layer forms bag on the position of packing bag mouth with inner plastic by the way that bonding agent is be bonded
Mouthful.The technical solution can eliminate the trouble of existing packaging bag flange sewing.
Preferably, the braiding layer is be bonded by bonding agent in the other positions of packaging bag with inner plastic.The skill
Art scheme can further increase the intensity of packaging bag.
Further include outer lining to reinforce the intensity of sewing place, which is wrapped in the outer bottom of packaging bag, the seam
Outer lining, outer layer and inner plastic are sewed together by line of threading.
Preferably, the outer lining is made of paper or plastic foil.
The present invention has reasonable for structure, high-quality, yield height, the advantageous effect of simple production process.
Description of the drawings
Fig. 1,2 be existing packaging bag structural schematic diagram.
Fig. 3 is the structural schematic diagram of packaging bag of the present invention.
Fig. 4 is the vertical view of Fig. 3.
Specific implementation mode
In conjunction with attached drawing, the present invention is further illustrated：
As shown, a kind of packaging bag, is made of outer layer 2 and inner plastic 3, outer layer 2 is sewed by sewing thread 11 and forms packaging
The outer bottom of bag is being provided with boiling hot trace line 5 on the position of sewing thread 11, this scalds trace line 5 and fuses outer layer 2 and inner plastic 3
Together, the interior bottom of packaging bag is formed.
Outer layer 2 and inner plastic 3 are sewed together by sewing thread 11.
Outer layer 2 is combined by packaging paper layer and braiding layer, wherein packaging paper layer is located at outermost layer.
Braiding layer forms sack on the position of packing bag mouth with inner plastic 3 by the way that bonding agent 6 is Nian Jie.
Braiding layer is be bonded by bonding agent 6 in the other positions of packaging bag with inner plastic 3.
Further include outer lining 4, which is wrapped in the outer bottom of packaging bag, and sewing thread 11 is by outer lining 4, outer layer 2 and moulds
Material internal layer 3 is sewed together.
Outer lining 4 is made of paper or plastic foil.
