Composite packaging bags are prone to breakage? How to find a high-quality supplier?

The rupture of composite packaging bags is a crucial factor affecting the suitability of the packaging and determines whether the bag can be used for product packaging. There are many factors that affect the rupture of composite packaging bags. Shunxingyuan Packaging, a professional flexible packaging manufacturer, analyzes these from four aspects below.

1. Peel Strength of Composite Film

If the peel strength of the composite film is too low, it is difficult to meet the requirements of multiple composite materials being subjected to force simultaneously, resulting in poor force dispersion. This can cause bag rupture during drops. In addition, in high-temperature sterilization bags, due to the poor heat resistance of some adhesives, especially in some complex structures (such as BOPAl5/Al7/CPP70), high-temperature sterilization can also cause cracking at the sealing edges and delamination of the composite film.

2、 In terms of bag-making process

Excessive bag-making temperature causes a decrease in the performance of the heat-sealing material at the heat seal, thus affecting bag rupture; excessive bag-making pressure causes the heat-sealing material at the heat seal to be squeezed out, reducing the heat-sealing material of the seal, thus causing the packaging bag to rupture when dropped. A too sharp heat-sealing bar during bag making, or mechanical flying spurs, can also damage the heat-cut edges of the bag, causing rupture.

3、 In terms of materials

The material must have sufficient thickness. Insufficient thickness will result in insufficient strength of the composite film, causing bag rupture. Pay attention to the addition of recycled materials; recycled materials will reduce various aspects. Adding too much will result in insufficient composite film strength, causing bag rupture. In the manufacturing process of PE film, LLDPE and mPE are added to improve the strength and flexibility of PE, thus reducing bag rupture. If used in low-temperature freezing environments, packaging must use low-temperature-resistant packaging materials (such as BOPA) to produce composite films; otherwise, the composite film will crack in low-temperature freezing environments.

4、 Other aspects

When packaging heavy or powdery items such as salt and washing powder, after filling these items, the air inside the bag should be expelled before heat sealing to reduce the stress on the packaging bag wall, allowing the solid matter to bear the force directly to reduce bag damage.
