Guangzhou Pioneer Technology Co., Ltd.

The water-soluble film and water-soluble bag are made of polyvinyl alcohol (PVA) and other water-soluble additives, which have two degradation characteristics, water and biological, first dissolved in water to form a glue deep into the soil, increase the soil mass viscosity, air permeability and water retention, especially suitable for sand soil transformation. PVA in soil can be broken down by strains of bacteria isolated in the soil, called nail monocells. A symbiotic system consisting of at least two bacteria can degrade PVA: one that is the active bacterium of PVA and the other that produces the substances required by the active bacterium of PVA. PVA sec-alcohol oxidase catalyzes PVA, and then hydrolase cuts the oxidized PVA backbone for further degradation, which can eventually be degraded to CO2 and H2O.
The water-soluble film produced by our company is mainly used in the following fields: water-soluble film pesticide chemical packaging, water-soluble film laundry washing liquid packaging, concrete additives water-soluble winding film, water-soluble film for embroidery, water-soluble film for toilet cleaning block blue bubble packaging, water-soluble surface printing water transfer film, water-soluble film packaging water treatment agent, hospital water-soluble anti-infection laundry bag, water-soluble toilet flushable pet garbage collection bag, water-soluble prosthetic mold release bag, marble release film, water-soluble supermarket shopping bag and gift bag, hot water soluble non-woven bag, Water-soluble garment packaging bags, hot-melt adhesive films and metal surface protective films, etc.
Water-soluble membranes have the following characteristics:
1. Soluble in water, no residue when used, and the formula can be adjusted to make the product dissolve at different water temperatures.
2. Excellent barrier performance; In addition to moisture and ammonia, PVA film has superior barrier properties to oxygen, nitrogen, helium, argon and carbon dioxide, etc., and its oxygen permeability coefficient is the lowest among various resin films under dry conditions, which makes PVA film can maintain the composition of the packaged product and its own odor. The excellent fragrance retention and anti-sublimation performance of the packaging make the use of PVA film packaging not only maintain the fragrance of the packaging well, but also prevent the packaging from being affected by the outside world. In addition, the moisture permeability of PVA film can be used in some packaging aspects to ensure that no fog droplets are generated when packaging hot and wet items.
3. PVA film has almost no static electricity and good oil resistance
In the process of using PVA film to package products, it will not cause static electricity and particles, and it has excellent oil resistance (vegetable oil, animal oil, mineral oil, fat resistance), organic solvent and carbohydrate resistance, which makes PVA film have a wider application prospect in the packaging of many special products.
4. Good printabilityPVA film has excellent water color and ink printability, and does not need corona treatment when printing.
