/ paper-plastic bag advantage is introduced:
1, the intensity is high, the inner layer is PP or PE woven cloth, the outer layer is refined composite paper, intermediate for composite plastic, this product has a strong characteristic of the puncture resistance, resistance to tear.
2, form beauty: select yellow or white kraft paper bagproduction, three color printing, Korea.
3, the sliding resistance good: choose against sliding in 25 degrees above paper, simple together.
zhisu composite bag suitable for:
chemical raw materials, food additives, medicine additive, building materials and so on all is suitable for composite paper-plastic bag packing work.
how to detect the quality of composite paper-plastic bag
1, the permeability
vacuum method take five bags, bags/practice contents or similar content, thermal sealing,
Based on the thermal conditions of the production process to choose)
In the rack, after experiment in pressure container into the appropriate colored solution (
Such as water) with ink added
, with sample rack is completely in nonferrous, fixed rack covered container, beginning to 27 vacuum kpa, guaranteed for 1 min, survey experiment bags have bubbles, after the experiment open experiment sample survey for the water seepage.
2, compression utility
take 5 bag, bag filling about half bag of capacity of the water, and a thermal sealing (
Based on the thermal conditions of the production process to choose)
。
Put on the sample one by one, between the lower.
Experiment level of upper and lower plate should stick to, not deformation, touch the surface with bags of lubrication is necessary, the area should be greater than the bag, were.
According to the regulations of table 3 add weight adhere to 1 minute,
The load of platen and Jordan farmar combined weight)
, visual, and may not be divided or leak.
3, drop function
take 5 bag, bag filling about half bag of capacity of the water, and a thermal sealing (
Based on the thermal conditions of the production process to choose)
Height of the sample, according to table 4 one by free fall on the level of the lubrication, hard (
Such as concrete)
。
Visual and may not be split.
