Abstract
The utility model discloses a double-layer vacuum compression bag, which comprises a bag body, wherein the bag body consists of a front sheet and a back sheet, the front sheet and the back sheet are bonded through hot pressing, and an inflating joint is arranged on the front sheet. The double-layer vacuum compression bag is characterized in that the front sheet and the back sheet are respectively formed by bonding an outer layer film and an inner layer film through hot pressing, and two opening sealing strips are bonded in positions of a bag body opening of the inner layer film. Compared with the prior art, the double-layer vacuum compression bag has the advantages that the double-layer vacuum compression bag has higher intensity, better puncture-resistant performance and higher flexibility than those of the traditional vacuum compression bag, and the double-layer vacuum compression bag cannot be easily damaged.
Description
Technical field
The utility model relates to a kind of double-layer vacuum compressed bag, belongs to household articles technical field.
Background technology
Traditional large-scale vacuum compressed bag, the manufacturing way of air bag are single blowing or two blowing, and generally, the bag of compressed bag is made up of laminated material (nylon adds polyethylene) individual layer, and intensity is little, and not puncture-resistant is easily damaged.
Utility model content
The utility model is in order to solve above-mentioned deficiency, and a kind of double-layer vacuum compressed bag is provided.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of double-layer vacuum compressed bag, comprise bag, described bag is made up of positive and tergite, positive and tergite are by being hot bonding, positive is provided with gas-charging connection, it is characterized in that: described positive and tergite are hot bonding formation by outer membrane and internal layer membrane, the bag opening part of described internal layer membrane has been hot bonding sealing strip, and described sealing strip is set to two.
Further, described outer membrane is made up of nylon laminating polyethylene or PET laminating polyethylene.
Further, described internal layer membrane is made up of polyethylene, is preferably polyethylene multilayer coextruded film.
The utility model advantage is compared with prior art: the more traditional vacuum compression bag intensity of the utility model is larger, and more puncture-resistant, has good elasticity, not cracky.
Brief description of the drawings
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of double-layer vacuum compressed bag, comprise bag 1, described bag 1 is made up of positive 2 and tergite 3, positive 2 and tergite 3 are by being hot bonding, and positive 2 is provided with gas-charging connection 4, it is characterized in that: described positive 2 and tergite 3 are hot bonding formation by outer membrane 5 and internal layer membrane 6, the bag opening part of described internal layer membrane 6 has been hot bonding sealing strip 7, and described sealing strip 7 is set to two.
Further, described outer membrane 5 is made up of nylon laminating polyethylene or PET laminating polyethylene; Described internal layer membrane 6 is made up of polyethylene, is preferably polyethylene multilayer coextruded film.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification sheets and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
