Current society develops very fashion, everything is innovating. The food packing bag also not behind the times. The continuous innovation of eight sides seal food packaging bags through its own advantages, in the packaging market received a warm welcome.
In actual use, a certain number of bags will break. The broken bags will affect the quality of packing. In fact, there are many factors that affect the rupture of eight-side sealed food packaging bags. Let me show you the cause of the rupture
1、Bag making process
The bag-making temperature is too high, causing the performance of the heat-sealing material at the heat-sealing part to decrease, thereby affecting the bag-breaking rate of bagging; The pressure of making the bag is too large, causing the heat-sealing material at the heat-sealing part to be squeezed out, and the heat-sealing effect of the door is reduced, causing the bag Bag broken bag.
2、Material aspect
The material must have enough sufficient thickness. The insufficient thickness will result in insufficient strength thickness. Then make the bag broken. the addition of recycled materials in the material, too much addition, insufficient strength of the packaging bag, will also cause broken bags.
3、The impact of packaging
When packing some heavy or powder items, such as salt, washing powder, etc., after filling such items, Before heat sealing, the air in the bag should be discharged to reduce the force on the wall of the packaging bag, so that the solid objects are directly stressed, And reduce the breakage of the bag.
4、Peel strength of the composite film
Eight-side seal packaging bags should also pay attention to the strength of the composite film. If the peel strength of the composite film is too low, it will be difficult to meet the requirements of multi-layer composite materials under stress at the same time, the force can not be better dispersed, so in the process of falling it will cause the bag to break. In addition, in high-temperature cooking bags, some adhesives have poor heat resistance.
Especially In some complex structures, during high-temperature cooking, it will also cause rupture at the edge of the seal, and delamination of the composite film can be used.
Since the development of SUNKEY Packaging, honesty is our first criterion, whether it is broken bags or small defects such as wrinkles. We will not sell it, so you can buy with confidence.
