Description
Technical field
The present invention relates to a kind of packaging bag, especially a kind of High-temperature-rescylinder cylinder material double-bottom-sealinbag bag, belongs to the technical field of bottom-sealed bag.
Background technology
Current cylinder material bottom-sealed bag purposes is relatively more extensive, and market top cylinder material bottom-sealed bag kind is also more various, such as polyethylene cylinder material bottom-sealed bag, nylon polyethylene co-extrusion film cylinder material bottom-sealed bag etc.Bottom-sealed bag bag there will be underseal void envelope phenomenon often, loads liquid (particularly high-temp liquid) and easily occurs Seepage afterwards.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of High-temperature-rescylinder cylinder material double-bottom-sealinbag bag, it is simple and compact for structure, and resistance to elevated temperatures is good, can avoid high temperature seepage, wide accommodation, safe and reliable.
According to technical scheme provided by the invention, described High-temperature-rescylinder cylinder material double-bottom-sealinbag bag, comprises envelope body, arranges the first edge sealing and second edge sealing spaced with described first edge sealing at the bottom of the bag of described envelope body; Envelope body comprises the first polyamide film layer, and described first polyamide film layer is bonded with the first polyethylene film layer, and described first polyethylene film layer is bonded with the second polyamide film layer, and described second polyamide film layer is bonded with the second polyethylene film layer.
The width of described first edge sealing is 5 ~ 8mm, and the width of the second edge sealing is 5 ~ 8mm, is spaced apart 4 ~ 6mm between the first edge sealing and the second edge sealing.
Described first polyethylene film layer is arranged on the first polyamide film layer by the first articulamentum bonding, second polyamide film layer is arranged in the first polyethylene film layer by the second articulamentum bonding, and the second polyethylene film layer is arranged on the second polyamide film layer by the 3rd articulamentum bonding.
The thickness of described first polyamide film layer is 15 ~ 20 μm, and the thickness of the first polyethylene film layer is 18 ~ 20 μm, and the thickness of the second polyamide film layer is 15 ~ 20 μm, and the thickness of the second polyethylene film layer is 35 ~ 40 μm.

Description of reference numerals: 1-first polyamide film layer, 2-first articulamentum, 3-first polyethylene film layer, 4-second articulamentum, 5-second polyamide film layer, 6-the 3rd articulamentum, 7-second polyethylene film layer, 8-first edge sealing, 9-second edge sealing and 10-envelope body.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2: in order to bottom-sealed bag can be made, there is good high-temperature resistant result, avoid occurring seepage during high temperature, the present invention includes envelope body 10, the first edge sealing 8 and second edge sealing 9 spaced with described first edge sealing 8 are set at the bottom of the bag of described envelope body 10; Envelope body 10 comprises the first polyamide film layer 1, and described first polyamide film layer 1 is bonded with the first polyethylene film layer 3, and described first polyethylene film layer 3 is bonded with the second polyamide film layer 5, and described second polyamide film layer 5 is bonded with the second polyethylene film layer 7.
Particularly, the width of described first edge sealing 8 is 5 ~ 8mm, and the width of the second edge sealing 9 is 5 ~ 8mm, is spaced apart 4 ~ 6mm between the first edge sealing 8 and the second edge sealing 9.By arranging the first edge sealing 8 and the second edge sealing 9 in the bottom of envelope body 10, edge sealing void can be avoided to seal the leakage scenarios caused.
Described first polyethylene film layer 3 is arranged on the first polyamide film layer 1 by the first articulamentum 2 bonding, second polyamide film layer 5 is arranged in the first polyethylene film layer 3 by the second articulamentum 4 bonding, and the second polyethylene film layer 7 is arranged on the second polyamide film layer 5 by the 3rd articulamentum 6 bonding.In the embodiment of the present invention, first articulamentum 2 is between the first polyamide film layer 1 and the first polyethylene film layer 3, second articulamentum 4 is between the first polyethylene film layer 3 and the second polyamide film layer 5, and the 3rd articulamentum 6 is between the second polyamide film layer 5 and the second polyethylene film layer 7.
The thickness of described first polyamide film layer 1 is 15 ~ 20 μm, and the thickness of the first polyethylene film layer 3 is 18 ~ 20 μm, and the thickness of the second polyamide film layer 5 is 15 ~ 20 μm, and the thickness of the second polyethylene film layer 7 is 35 ~ 40 μm.The thickness of described first articulamentum 2 is 2 ~ 3 μm, and the thickness of the second articulamentum 4 is 2 ~ 3 μm, and the thickness of the 3rd articulamentum 6 is 2 ~ 3 μm.
