China What is the reason for the layering of plastic packaging bags? Wholesale Factory

The layering phenomenon of plastic packaging bags during use can lead to problems such as packaging breakage and leakage, affecting the safety and aesthetics of the product. So, what is the reason for the layering of plastic packaging bags? The following analysis will help everyone understand the reasons for the layering of plastic packaging bags, in order to take corresponding preventive measures.

Quality issues with raw materials
A common reason for the layering of plastic packaging bags is poor quality of raw materials. If the plastic raw materials used by manufacturers contain impurities, excessive recycled materials, or substandard quality, it will lead to a decrease in the strength and stability of plastic packaging bags, resulting in delamination.
Production process issues
The production process has a significant impact on the quality of plastic packaging bags. If the temperature, pressure, speed and other parameters are not properly controlled during the production process, or if the equipment is worn or not cleaned properly, it may lead to delamination of plastic packaging bags. In addition, insufficient cooling and uneven stretching during the production process may also lead to delamination.
Printing issues
In the printing process of plastic packaging bags, if the ink is not selected properly or the printing process is not suitable, it will cause the ink layer to not bond firmly with the plastic substrate, resulting in layering. Especially for some special materials of plastic packaging bags, such as polyethylene (PE), polypropylene (PP), etc., suitable ink and technology should be selected when printing.
Storage and transportation issues
Plastic packaging bags may also experience layering during storage and transportation. For example, prolonged exposure to high temperature and humid environments, or exposure to severe impacts, friction, etc., can lead to delamination of plastic packaging bags.
Improper use
Consumers may also experience layering when using plastic packaging bags. Excessive stretching, sharp object scratches, and high-temperature heating can all damage the structure of plastic packaging bags, leading to delamination.

To avoid layering of plastic packaging bags, the following points should be noted during production and use:

Select high-quality raw materials to ensure the quality of the substrate for plastic packaging bags.
Strictly control production process parameters to ensure the normal operation and cleanliness of production equipment.
Choose suitable ink and printing technology to ensure printing quality.
Properly store and transport plastic packaging bags to avoid severe impacts, friction, etc.
Reasonably use plastic packaging bags to avoid excessive stretching, sharp objects scratching, etc.

The layering of plastic packaging bags is caused by various reasons. Understanding the reasons for layering and taking corresponding preventive measures can effectively reduce the risk of plastic packaging bag layering, ensuring product safety and packaging aesthetics.
