It is a kind of polyvinyl alcohol-based material, belongs to a biodegradable polymer material, referred to as PVA. Adding additives such as modifiers, after special processing, can be completely degraded by microorganisms in the soil, is a green environmental protection functional material. It can be degraded into carbon dioxide and water in a short time, and has the effect of improving the land.
Polyvinyl alcohol (PVA) is the only vinyl polymer that can be used as a carbon source and energy source by bacteria, with a density of 1.26-1,29g/cm3, a refractive index of 1.52, and a blue-white light after ultraviolet irradiation. The film has strong water absorption, can be dissolved in water, the moisture content of the fiber can reach 30%-50%, and the moisture content can also reach 4.5% under 65%RH and 25℃ environment. It can pass through water vapor, but it is difficult to pass through alcohol vapor, and it cannot pass through organic solvent vapor.
Polyvinyl alcohol (PVA) is a water-soluble polymer, which is characterized by good density, high crystallinity, strong adhesion, flexible and smooth film, oil resistance, solvent resistance, abrasion resistance, good gas permeability resistance, and a wide range of applications.
Polyvinyl alcohol is non-toxic, tasteless, harmless to the human body, has a good affinity with the natural environment, does not accumulate, no pollution.
The biggest advantage of PVA film is water solubility and environmental protection.
Application field
Water Transfer Printing hydro dipping
Water Transfer Printing technology, also known as Cubic transfer technology (Cubic Transfer), it is used Water-soluble film (PVA film) to carry graphics, and water is used as a dissolving medium to transfer color patterns to other objects.
Because water transfer film tension is excellent, it is easy to wrap around the surface of the product to form a graphic layer, and the surface of the product is like spray paint to get a completely different appearance. Can be transferred to any shape of the item, for manufacturers to solve the problem of three-dimensional (3D) product printing.
Most of the materials we see in our daily life are suitable for Water Transfer Printing, such as glass, metal, ceramics, plastics, wood products, silicone and so on. Many factories through theWater Transfer Printing technology to make their products look unique, have resolution, products are competitive in the market, expand their market, and massively increase the sales volume.

Acrylic Solid surface release film
The features of pure acrylic artificial stone: seamless splicing, antibacterial and anti-fouling, direct contact with food, excellent weather resistance and mechanical properties; Very good toughness, can be bent arbitrarily after heating, thermoplastic processing is its most significant features.
Application areas are: decoration, medical, catering, art
Decoration industry: Pure acrylic solid surface has good cold and heat resistance and impact resistance. As a decorative material with superior texture and rich colors, it can not only beautify indoor and outdoor decoration, meet the diversified needs of design, but also provide a broad space for architects and designers to play and express a supernatural feeling.
Medical field:
Pure acrylic solid surface, with antibacterial, stain resistance and flame retardant properties, is a must for hospital decoration materials.
Often used in operating room curtain wall, operating table, pharmacy, laboratory, etc.
Detergent pods packing bag
Laundry detergent pods film does not dissolve, does not leak, does not break in a dry environment, and can dissolve in 1 minute after encountering water. As an innovative laundry product, it brings convenience to people’s lives.
At the same time, the Laundry detergent pods film will also be dissolved by water and discharged into the sewer through sewage, which is decomposed into carbon dioxide and water, which is non-toxic and harmless to the human body.
For those who do not like to measure the dosage, the use of detergent pods can easily solve this problem, it can help you better control the amount of laundry detergent used, and there are many different sizes of coagulants on the market now.
Agricultural packing bag
Pesticide water-soluble bag is characterized by fast water dissolution and no residue, and is mainly used for disposable packaging bags and internal packaging materials that are not suitable for human contact with products. No pollution, no toxicity, degradation into water and carbon dioxide; Anti-static, tensile strength, tension uniformity, no dust; Using heat sealing, the temperature is 180℃-240℃ heat sealing performance is good.
Application: pesticide powder granules, fuel, cleaning supplies, medical washing bags.
With the promotion of polymer water-soluble film, the application field will soon be popularized to food, medicine, medical, clothing, embroidery, cosmetics, cleaning agents, dyes, pigments, fertilizers, feed, water treatment agents, mineral additives, detergents, concrete additives, photographic chemicals and horticultural care chemicals and other items packaging.
Isolation laundry bag
Infection-proof water-soluble medical disposal bags minimize the risk of cross-infection between health care workers, patients and contaminants. After the contamination is encapsulated, the contents are completely isolated during the entire process from being transported to cleaning, disinfection, and drying, avoiding direct contact with contaminants by medical personnel and effectively preventing the spread of germs. The disposal bag is completely dissolved in the process of cleaning and disinfection, and no polluting residue packaging is produced.
Suitable for hospitals, hotels, laundry, nursing homes
Polarizing film
The components of polyvinyl alcohol (PVA) film are mainly light atoms such as hydrogen and oxygen, with high transparency and high ductility, as well as good iodine adsorption and film formation characteristics, which is the core raw material of polarizer.
PVA film can play a polarizing role because it can adsorb bidirectional molecules. Taking iodine PVA film, which is widely used in the market, as an example, PVA molecular chains are disordered before treatment, and the iodine molecules adsorbed on PVA film are also disorganized. When PVA film is extended and oriented, the iodine molecules on PVA film are also orderly distributed, and the bidirectional absorption molecules adsorbed iodine extend and coordinate. The PVA film has the function of polarizing light, so as to determine the polarizing performance, transmittance, tone and other key optical indicators of the polarizer.
