The production process of Biodegradable wicketed bags is indeed more complicated than that of traditional plastic bags, which is mainly reflected in the following aspects:
1. Material selection:
The selection of biodegradable materials (such as PLA, PBAT, etc.) is more complicated than that of conventional plastic materials, because it is necessary to ensure that the materials have sufficient strength, transparency and processability during use. At the same time, these materials need to be naturally degraded in the environment to reduce pollution to the environment.
2. Film layer composite technology:
Biodegradable bags often use a multi-layer film structure to enhance the strength, durability and moisture resistance of the bag. During production, the composite process of the film layer is more complicated because it is necessary to ensure that each layer of the film can remain stable during the degradation process and achieve the desired packaging effect.
3. Wicket binding:
In the production process of biodegradable wicketed bags, the wicket (hook) needs to be firmly bound to the bag for fast and efficient bagging operations on the automated packaging line. This process involves special treatment and strengthening of biodegradable materials to ensure that the connection between the hook and the bag is not easy to fall off and does not affect the biodegradability of the bag.
4. Printing and customization:
The printing of biodegradable bags requires the use of environmentally friendly inks, and the drying and adhesion of these inks may be different from those of conventional plastic bags. When customizing the printing design, it is necessary to ensure that the ink does not affect the degradation performance of the bag and does not release harmful substances during the degradation process.
5. Product testing:
Due to the characteristics of biodegradable materials, more tests are required during the production process, including degradation performance, strength testing, and wear resistance testing. These tests ensure that the product meets environmental standards while maintaining sufficient strength in actual use.
The production process of biodegradable wicketed bags is relatively complex, involving material selection, film layer lamination, printing technology and other aspects. At the same time, it is also necessary to ensure that the bag has sufficient functionality and practicality while meeting environmental requirements. Therefore, compared with traditional plastic bags, its manufacturing process requires more fine control and technical investment.
