Abstract
The utility model 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 sewing sewer, 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 by the way that bonding agent is be bonded on the position of packing bag mouth with inner plastic.The braiding layer is Nian Jie by bonding agent in the other positions of packaging bag with inner plastic.It 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 utility model has structurally reasonable, high-quality, yield height, the beneficial effect of simple production process.
Description
Technical field
The utility model relates to a kind of packaging bags.
Background technique
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 choose 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, the outer layer 2 of sack will be moulded to in-flanges together with outer layer 2 is made sewing thread 11 with inner plastic 3
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, 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.
Utility model content
The utility model can obviously simplify processing technology according to the above deficiency, provide a kind of packaging bag, simplify processing and set
It is standby, while ensuring that packaging bag is air tight.
The technical solution of the utility model is:
A kind of packaging bag, is made of outer layer and inner plastic, and outer layer forms the outer bottom of packaging bag by sewing sewer,
It is provided with boiling hot trace line on the position of sewing thread, this scalds trace line and fuses together outer layer and inner plastic, forms packaging bag
Interior 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 by the way that bonding agent is be bonded on the position of packing bag mouth with inner plastic
Mouthful.The technical solution can eliminate the trouble of existing packaging bag flange sewing.
Preferably, the braiding layer is Nian Jie by bonding agent in the other positions of packaging bag with inner plastic.The skill
Art scheme can be further improved the intensity of packaging bag.
It 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 utility model has structurally reasonable, high-quality, yield height, the beneficial effect of simple production process.
Detailed description of the invention
Fig. 1,2 be existing packaging bag structural schematic diagram.
Fig. 3 is the structural schematic diagram of the utility model packaging bag.
Fig. 4 is the top view of Fig. 3.
Specific embodiment
The utility model is further described now in conjunction with attached drawing:
As shown, a kind of packaging bag, is made of outer layer 2 and inner plastic 3, outer layer 2 is formed by the sewing of sewing thread 11
The outer bottom of packaging bag is provided with boiling hot trace line 5 on the position close to sewing thread 11, this scalds trace line 5 for outer layer 2 and inner plastic 3
It fuses together, forms the interior bottom of packaging bag.
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 by the way that bonding agent 6 is Nian Jie on the position of packing bag mouth with inner plastic 3.
Braiding layer is be bonded by bonding agent 6 in the other positions of packaging bag with inner plastic 3.
It 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.
