Woven bags produced by plastic packaging plants are widely used by the public. Some products produced by an enterprise are shipped to various places in woven bags. How do enterprises distinguish the quality when wholesale woven bags? Good quality woven bags are durable and strong and have a high recovery rate, which can be reused, and also leave considerable investment for enterprises.
The quality of woven bags can be viewed from two aspects:
One is the surface gloss of the woven bag, and the method of improving the gloss of the plastic woven bag includes two meanings.
On the one hand, it is to improve the surface gloss of plastic woven bag products, called brightening
On the other hand, it reduces the surface gloss of plastic woven bag products and becomes matt modified.
In addition to the reasonable selection of raw materials, the specific methods of brightening plastic woven bags include the methods of adding brightening, blending brightening, morphological control brightening, molding equipment smoothness control, secondary processing brightening and surface coating. Layer brightening method, etc. The selection of plastic woven bag materials can be divided into two categories: resin and additives. It is generally believed that the products corresponding to the following resins have better gloss: melamine resin, ABS, PP, HIPS, PA, POM, PMMA, PPO, etc., of which melamine resin and ABS are the most prominent two gloss.
In order to deal with the problem of uneven printing and low level of monofilament tensile strength after laminating plastic woven bags. Hengyan woven bag factory summarized the practical production experience and conducted a technical analysis of the product. After more than a year of skill improvement and equipment transformation depiction, It has broken through the process requirements in the previous textbooks and skill materials. Through the improvement of process skills, the transformation of the processing equipment and the formulation of quality specifications, the flatness of the woven bag has been improved to ensure the quality of new products.
The appearance of the general plastic woven bag is not very good due to the interweaving of warp and weft. The flatness and lubricity of the plastic woven bag are not very good. The unevenness of the surface of the plastic woven bag makes the printed picture uneven. To obtain a better printing effect, the flatness of the plastic woven bag needs to be improved And then print. This not only improves the flatness, but also provides a very adaptable printing surface for printing.
