Description
Technical field
The present invention relates to the production technology of packaging bag, be specifically related to the production technology of a kind of easy-peeling packaging bag.
Background technology
Packaging bag, eats article or small articles etc. for device, uses the benefit of plastic packaging bag for using
Life-span is long, cost-effective, and lightweight.
In prior art, in plastic packaging bag product, bag stock material is directly buying, packaging bag interior
Layer is covered with PE film, and it is the safest that this film directly contains food, needs tearing packaging bag when
Duroplasts tie rod to be used, is pulled open the outer layer of sack by force by tie rod, can throw away after pulling open, the hardest
The extremely difficult degraded of plastic bracing, seldom or does not recycles, and therefore can cause increase and the production technology of cost
Increase, easily cause the pollution of environment and the waste of material simultaneously；The inner space of general existing packaging bag
Less, therefore capacity is less, can not seal in time when food is not eaten up, or the sealing effectiveness of sealing is not
Good, existing plastic fastener be difficult to docking in pressing, when junction around packaging bag is hermetically sealed, hold
Being easily formed bubble and wrinkling, therefore sealing also is difficult to ensure.
During this packaging bag of existing production, it is generally required to the internal layer that advanced person is about to buy is covered with the packaging of PE film
Paper, at outer layer printed patterns, then carries out covering the EVP film (sub-light film) of protection pattern on pattern, re-uses
UV technique carries out gold stamping or silver-colored, then carries out recessed for the tie rod sealing part being pressed in packaging bag, and existing recessed pressure is to need
Version to be seted the tone, the cost of this version of setting the tone is higher, and 2 sets just need to spend about 10,000 yuan, therefore increases
Cost, then carries out sealing part and is scalded up by slide fastener, then carries out folding edge sealing；And existing technical process
Relatively time-consuming, relatively costly, easily cause defect rate high.
