Abstract
The utility model discloses a kind of packaging bags, are made of outer layer and inner plastic, characterized in that outer layer forms sack by the way that bonding agent is be bonded on the position of packing bag mouth with inner plastic.Sliding is generated between outer layer and inner plastic in order to prevent, the outer layer is Nian Jie by bonding agent in the other positions of packaging bag with inner plastic.The outer layer is combined by packaging paper layer and braiding layer, wherein packaging paper layer is located at outermost layer.In order to improve the reliability of sack, meanwhile, taking into account reduces cost, preferably, the adhesive spots at the sack are uniformly gathered.Adhesive spots spacing at the sack is 1-3cm.The size of adhesive spots is controlled in 0.5-1 cm.Adhesive spots spacing in the other positions of the packaging bag is 5-20cm.The size of the adhesive spots is 0.5-1cm.The utility model has structurally reasonable, and sack is air tight, and yield is high, 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 is wrapped up to be sewed with sack line 12, which has sewing hole can gas leakage due to inner plastic 3；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
It is relatively good to pack bag sealed bottom performance, but sack needs sewing also can gas leakage.
Utility model content
The utility model can ensure that the sack of packaging bag is air tight according to the above deficiency, provide a kind of packaging bag.
The technical solution of the utility model is:
A kind of packaging bag, is made of outer layer and inner plastic, characterized in that outer layer and inner plastic are in packing bag mouth
It is bonded to form sack by bonding agent on position.
When needing in the air tight encapsulation of sack, outer layer and inner plastic are fused together by high temperature hot melt.
Sliding is generated between outer layer and inner plastic in order to prevent, the outer layer and inner plastic are in other positions of packaging bag
It sets and is bonded by bonding agent.
Preferably, the outer layer is combined by packaging paper layer and braiding layer, wherein packaging paper layer is located at outermost layer.
In order to improve the reliability of sack, meanwhile, taking into account reduces cost, preferably, the adhesive spots at the sack are equal
It is even to gather.
Preferably, the adhesive spots spacing at the sack is 1-3cm.
The size of adhesive spots is controlled in 0.5-1 cm.
Preferably, the adhesive spots spacing in the other positions of the packaging bag is 5-20cm.
The utility model has structurally reasonable, and sack is air tight, and yield is high, 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 and inner plastic 3 are in packaging bag bag
Sack is formed by the bonding of bonding agent 6 on the position of mouth.
Outer layer 2 is be bonded by bonding agent 6 in the other positions of packaging bag with inner plastic 3.
Outer layer 2 is combined by packaging paper layer and braiding layer, wherein packaging paper layer is located at outermost layer.
Adhesive spots at sack are uniformly gathered.
Adhesive spots spacing at sack is 1-3cm.
Adhesive spots spacing in the other positions of packaging bag is 5-20cm.
In order to which the bag bottom for reaching packaging bag is also air tight, outer layer 2 sews the outer bottom for forming packaging bag by sewing thread 11,
It is provided with boiling hot trace line 5 on the position of sewing thread 11, this scalds trace line 5 and fuses together outer layer 2 and inner plastic 3, is formed
The interior bottom of packaging bag.
Outer layer 2 and inner plastic 3 are sewed together by sewing thread 11.
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.
The size of adhesive spots is 0.5-1cm.
