Abstract
The utility model provides an aluminum plastic composite vacuum package bag which is flat in bag shape. The structural design of the aluminum plastic composite vacuum package can eliminate stress concentration. The aluminum plastic composite vacuum package bag is good in sealing performance and high in hot seal strength. A bag body of the package bag is provided with a bottom seal and a back seal, a back sealing strip with the length identical with the length of the bag body is arranged at the position of the back seal, and two butt joint side portions of the bag body are integrally connected through the back sealing strip. The back sealing strip is of a three-layer structure. Three layers are respectively a polyethylene (PE) layer, an aluminum layer and a PE layer.
Description
Technical field
The utility model relates to a kind of packing, relates to specifically a kind of plastic-aluminum combined vacuum packaging bag.
Background technology
Plastic-aluminum combined vacuum packaging bag, this series products are applicable to protection against the tide, lucifuge, the vacuum packaging of large-scale precision mechanical equipment, chemical raw material, medicine intermediate.
The base material of existing plastic-aluminum combined vacuum packaging bag, structure is generally three layers (or four layers), structure is followed successively by from inside to outside: PE layer (internal layer is heat sealable), Al layer (middle level barrier layer), PET(skin are not heat sealable), this back of the body seal structure is that the PE layer hot pressing by the aluminum-plastic composite membrane on both sides forms.This packaging bag is feeded rear structure as shown in Figure 1, and the shortcoming of the packaging bag of this kind back of the body seal structure is:
1, formation stress in back of the body envelope place is concentrated, so impact resistance is poor.
2, back of the body envelope place projection is unfavorable for stacking.
Summary of the invention
The utility model provides a kind of plastic-aluminum combined vacuum packaging bag, and this packaging bag bag shape is smooth, and its structure design can eliminate stress concentrated, good airproof performance, and heat seal strength is high.
The utility model is achieved through the following technical solutions:
A kind of plastic-aluminum combined vacuum packaging bag, the bag of this packaging bag are provided with underseal and back of the body envelope, and it is characterized in that: described back of the body envelope place is provided with a back of the body strip of paper used for sealing suitable with bag length, and this back of the body strip of paper used for sealing connects as one the both sides section of bag docking.
The bag inner face is located in described back of the body strip of paper used for sealing position, and this back of the body strip of paper used for sealing is connected by the both sides section of heat-sealing with the bag docking.
This back of the body strip of paper used for sealing inner and outer surface layers is PE layer structure, and this back of the body strip of paper used for sealing adopts three-decker, and three layers are followed successively by PE layer, aluminium lamination, PE layer.
Back of the body envelope is positioned at middle part, the bag back side or the position that takes over, takes back.
Four corners of bag are for being equipped with the oblique angle; The place, base angle of bag also can be provided with an one-way exhaust valve.
The utility model has following advantage compared to existing technology:
The plastic-aluminum combined vacuum packaging bag of the utility model design, its back of the body envelope adopts back of the body seal structure, and connects by heat-sealing, the packaging bag of this back of the body seal structure, it is concentrated to eliminate stress, thereby impact resistance is strong, good airproof performance; Back of the body envelope is smooth simultaneously, and the bag type is attractive in appearance, is beneficial to stacking.

The specific embodiment
The utility model will be further described for following structure accompanying drawing:
As shown in Figure 3, Figure 4, the 25kg of the utility model design fills plastic-aluminum combined vacuum packaging bag, and the bag of this packaging bag is provided with underseal and back of the body envelope, and back of the body strip of paper used for sealing suitable with bag length of this back of the body envelope employing 1 connects as one bag.This back of the body strip of paper used for sealing 1 is positioned at the bag inner face, and the both sides section heat-sealing that back of the body strip of paper used for sealing 1 docks with bag is shaped to one.Back of the body strip of paper used for sealing 1 adopts aluminum-plastic composite membrane, and it is followed successively by PE layer, aluminium lamination and PE layer from inside to outside.The packaging bag charging back of the utility model design seals shape as shown in Figure 2, and as seen from the figure, its back of the body envelope is smooth after the charging.
Four edges of plastic-aluminum combined its bag of vacuum packaging bag of the present utility model can also be equipped with oblique angle 3.The place, base angle of bag also can be provided with an one-way exhaust valve 2, in order to discharge the interior residual gas of bag in the pack process.
