Abstract
The invention relates to a high-temperature-resistant cylinder material double-bottom-sealing bag which comprises a bag sealing body. The bag bottom of the bag sealing body is provided with a first sealing edge and a second sealing edge, and the first sealing edge and the second sealing edge are arranged at intervals. The bag sealing body comprises a first polyamide membrane layer, a first polyethylene membrane layer is bonded to the first polyamide membrane layer, a second polyamide membrane layer is bonded to the first polyethylene membrane layer, and a second polyethylene membrane layer is bonded to the second polyamide membrane layer. The bag sealing body is formed through co-extrusion membrane blowing via the first polyamide membrane layer, the first polyethylene membrane layer, the second polyamide membrane layer and the second polyethylene membrane layer, so high-temperature resistance of the bag sealing body can be improved; the first sealing edge and the second sealing edge are arranged on the bottom of the bag sealing body, so high-temperature leakage caused by virtual sealing can be effectively avoided; the high-temperature-resistant cylinder material double-bottom-sealing bag is suitable for the field of food packaging, simple and compact in structure, wide in application range, safe and reliable.
Description
Technical field
The present invention relates to a kind of packaging bag, especially a kind of high temperature resistant cylinder is expected Double bottom envelope, belongs to the technical field of bottom-sealed bag.
Background technology
Cylinder material bottom-sealed bag purposes is more extensive at present, 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 the empty envelope of underseal phenomenon often, easily occurs Seepage after packing liquid (particularly high-temp liquid) into.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of high temperature resistant cylinder material Double bottom envelope is provided, it is simple and compact for structure, and resistance to elevated temperatures is good, can avoid high temperature seepage, and wide accommodation is safe and reliable.
According to technical scheme provided by the invention, described high temperature resistant cylinder material Double bottom envelope, comprises envelope body, a bag end for described envelope body arrange the first edge sealing and with spaced the second edge sealing of described the first edge sealing; Envelope body comprises the first polyamide rete, on described the first polyamide rete, is bonded with the first polyethylene film layer, is bonded with the second polyamide rete in described the first polyethylene film layer, on described the second polyamide rete, is bonded with the second polyethylene film layer.
The width of described the first edge sealing is 5 ~ 8mm, and the width of the second edge sealing is 5 ~ 8mm, between the first edge sealing and the second edge sealing, is spaced apart 4 ~ 6mm.
Described the first polyethylene film layer is arranged on the first polyamide rete by the first articulamentum bonding, the second polyamide rete 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 rete by the 3rd articulamentum bonding.
The thickness of described the first polyamide rete is 15 ~ 20 μ m, and the thickness of the first polyethylene film layer is 18 ~ 20 μ m, and the thickness of the second polyamide rete is 15 ~ 20 μ m, and the thickness of the second polyethylene film layer is 35 ~ 40 μ m.
The thickness of described the first articulamentum is 2 ~ 3 μ m, and the thickness of the second articulamentum is 2 ~ 3 μ m, and the thickness of the 3rd articulamentum is 2 ~ 3 μ m.
Advantage of the present invention: envelope body forms by coextrusion film blowing by the first polyamide rete, the first polyethylene film layer, the second polyamide rete and the second polyethylene film layer, can improve the resistance to elevated temperatures of envelope body, the bottom of envelope body arranges the first edge sealing and the second edge sealing, the high temperature seepage that can effectively avoid empty envelope to cause, be applicable to packaging for foodstuff field, simple and compact for structure, wide accommodation, safe and reliable.
