The woven bag produced by the plastic packaging factory is a product widely used by the general public. Some products produced by a company are loaded in woven bags and shipped to various places. How do companies distinguish the quality of woven bags when they are wholesale? Good-quality woven bags are durable and strong and have a high recycling rate, which can be reused, leaving a lot of capital investment for the enterprise. Woven bags The quality of woven bags can be viewed from two aspects:
One is the surface gloss of woven bags. The method of improving the gloss of plastic woven bags has two meanings.
On the one hand, it is to improve the surface glossiness of plastic woven bag products, which is called brightening modification. On the other hand, it is to reduce the surface glossiness of plastic woven bag products, which becomes a matting modification. In addition to the reasonable selection of raw materials, the specific methods of brightening plastic woven bags include adding brightening methods, blending brightening methods, morphological control brightening methods, and molding equipment smoothness control.
Secondary processing brightening methods and surface coating brightening methods, etc. The selection of raw materials for plastic woven bags, plastic raw materials can be divided into two categories: resin and additives. It is generally believed that the gloss of the products corresponding to the following resins is better: melamine resin , ABS, PP, HIPS, PA, POM, PMMA, PPO, etc. Among them, melamine resin and ABS have the most outstanding gloss. In order to deal with the problem of uneven printing and low monofilament tensile strength after plastic woven bag laminating, Hengyan woven bag factory summed up practical production experience and carried out technical analysis of the product. After more than a year of skill improvement and equipment transformation description, Breaking through the technical requirements in the previous textbooks and technical materials, through the improvement of technical skills, the transformation of processing equipment and the drafting of quality specifications, etc., the flatness of the woven bag has been improved to ensure the quality of new products.
Generally, the surface of plastic woven bags is not very flat and lubricated due to the interweaving of warp and weft. The uneven appearance of plastic woven bags makes the printed pictures uneven. In order to achieve better printing effects, it is necessary to improve the flatness of plastic woven bags. , And then print. This can not only improve the flatness, but also provide a very adaptable printing surface for printing.
