With the development of society, whether in the food (snack) industry or laundry detergent industry, the stand-up pouch is becoming more and more popular among them. However, sometimes we can inevitably find that stand-up pouches have produced the phenomenon of broken bags. Therefore, as a professional stand up pouch supplier, we will explain the reasons for the breakage of stand-up pouches.

1. Raw material.

(1) stand-up pouches in the choice of raw materials or, more careful, the choice of material thickness will cause insufficient strength of the composite film, which will cause the problem of broken bags.

(2) raw materials to join the recycled material, resulting in various aspects of performance reduction, resulting in broken bags.

2. Bag-making process.

(1) The high bag-making temperature will lead to a decline in heat-sealing material.

(2) excessive bag-making pressure will lead to the extrusion of heat-sealing materials.

(3) heat sealing strength will make stand-up pouches easy to break.

(4) heat sealing strip is too sharp or mechanical splintering, damaging the heat seal's edge.

3. In terms of the peel strength of the composite film.

(1) the peel strength of the composite film is too low. It is difficult to achieve the requirements of the simultaneous force of multi-layer composite materials.

(2) high-temperature cooking bag adhesive heat resistance is not good and will also cause the rupture of the sealing edge and the phenomenon of composite film delamination.

This is the reason why stand-up pouches break. Stand-up pouches will affect the product will affect not only the quality of the products sold but also more sales. To avoid the loss of this party's high cotton, looking for a good stand up pouch supplier is necessary.
