What is the production process of environmentally friendly non-woven bags

The production process of Zhoukou Hongyuan packaging can be divided into five steps, each of which is extremely important and has a unique effect on the quality of non-woven bags.

1. Cutting material. The so-called opening is to calculate the amount of raw materials based on the estimated weight of the finished non-woven bag. The calculation formula is: single non-woven bag weight X quantity + possible consumption. Due to the inevitable loss in the production process of non-woven bags, the opening weight is greater than the actual weight. Therefore, there are usually some errors between the actual production quantity and the predetermined quantity of non-woven bags.

2. Blow molding. This step is a key step in making non-woven bags. The raw materials are loaded into the blown film machine, and the machine automatically melts the raw materials and blows the film at the same time. The opening of the bag and the thickness of the non-woven bag are determined in this step. Generally speaking, if the speed of the blower is fast, the finished bag will be thin, and if the speed of the blower is slow, the finished bag will be thick.

3. Non-woven bag printing. In recent years, the demand for color printed non-woven bags has become higher and higher. According to customer needs, non-woven bag manufacturers need to use color printers to print patterns on plastic film bags according to established patterns. The key point of this step is plate making and pigment blending.

5. Cutting the film. This step is to reposition the length of the film and cut the film into semi-finished products according to the length of the non-woven bag required by the customer.

5. Making finished non-woven bags. This step is completed on the bag making machine, using a heat-sealing knife to seal the plastic film into a finished non-woven bag with only one opening, and the stitching width is also determined according to customized requirements.

Through the above five steps, an overall process for the production of Zhoukou Hongyuan Packaging non-woven bags is completed. However, because there are many types of non-woven bags on the market, the production of non-woven bags of different types and materials is different, simple and complex. In the above steps, the processing temperature, blow molding strength, etc. are involved. The factors are different, and the production process is also different. If you have any questions, please contact customer service.
