Description :

　　PVA water-soluble film polyvinyl alcohol mold:

　　Water soluble film is made of water-soluble polymer materials that can quickly dissolve in water, and is produced through a specific film-forming process. It is a novel green packaging material that is water-soluble, biodegradable, and widely used in various products such as clothing exports, pesticides, fertilizers, pigments, dyes, cleaning agents, water treatment agents, mineral additives, detergents, concrete additives, etc. in Europe, America, Japan, and other countries. It has the characteristics of easy solubility, oil and corrosion resistance, static electricity prevention, elasticity and tensile strength, accurate measurement, strong heat sealing, breathability and oxygen resistance, clear printing, and high anti-counterfeiting.

　　Product Application

　　(1) Inner packaging lining bags for pesticides and chemical products. Can avoid touching pesticides and chemical products with hands, and there are no residual pesticides in plastic bags;

　　(2) Packaging bags for cement additives (such as silica powder). Avoid environments with flying dust;

　　(3) Embroidery, wigs and other fabric carriers. Set off the carrier for easy cleaning;

　　(4) Artificial large stone demolding film. Place a water-soluble film inside the mold for quick demolding;

　　(5) Surface printing (water transfer printing). After printing on the film, it can be transferred onto a curved surface;

　　(6) Seed belt. Packaging seeds at fixed intervals and burying them underground can save valuable seeds and eliminate the busy process of intercropping;

　　(7) Hospital washing packaging bags. Clothes that do not require contact with pollution can also be cleaned;

　　(9) Hot water-soluble film suitable for clothing packaging;

　　(10) After being compounded with other plastics, it can be used for food preservation packaging and air cushion bags.

　　The PVA water-soluble film polyvinyl alcohol mold coating system designed by JWELL is used for continuous coating, which has the advantages of uniform coating and no stripes. Compared with traditional scraping coating process, it can improve the line speed and coating accuracy, while reducing the impact on the environment. In addition, compared with the traditional scraping coating process, the newly designed coating system can be used as an independent coating system or as a component of a complete coating workstation.

　　The line speed of traditional scraping coating process generally does not exceed 12m/min, while JWELL's designed slit coating can reach 60m/min

　　The coating process is a closed pre metering system, so compared with roll coating and other traditional open coating systems, it has high coating efficiency and good controllability. In traditional open coating systems, only a portion of the adhesive delivered to the substrate surface is actually coated onto the substrate surface, while the rest is recycled and reused. The seam die head avoids the contact between glue and the environment, thus preventing the discharge of coating materials in the workplace and also avoiding contamination of the coating materials themselves.
