PVOH 728F is a partially alcoholized, low molecular weight polyvinyl alcohol (PVOH) product, usually appearing as light yellow particles. It is specifically designed for the production of specialized PVOH grades used in PVA films. It has excellent properties such as water solubility, transparency, heat resistance, antistatic, etc., and has a wide range of application prospects in packaging, agriculture, medicine, and other fields.

Packaging: PVOH 728F can be used in the manufacture of water-soluble films, which dissolve quickly in contact with water and are suitable for industries requiring fast, convenient, and environmentally friendly packaging, such as cosmetics, food, and pharmaceuticals. PVOH 728F can also be used in the manufacture of difficult-to-solve films. These insoluble films can only dissolve under certain conditions, making them ideal for packaging needs that require product integrity and stability over long periods.
Agriculture: PVOH 728F can be used as a seed coating material. The coated seed can protect the seed from environmental factors, improve the germination rate and growth quality of the seed, and not pollute the soil. PVOH 728F can also be used to manufacture pesticide carriers by controlling the pesticide release rate and mode to improve the effectiveness of pesticide use and reduce the negative impact on the environment. Pharmaceutical field: PVOH 728F can be used as a component of a drug release system. By adjusting the dissolution rate of the film and the drug release mechanism, it is possible to realize the timed and quantitative release of the drug and improve the efficacy and safety of the drug. In addition, PVOH 728F can also be used to manufacture hygiene materials, such as disposable medical packaging, surgical gowns, etc. Its excellent biocompatibility and degradability can meet the requirements of safety and environmental protection in the field of medical and health care.

Packaging: Sealed with materials with moisture-proof properties, weight 25kg/bag.
Storage：The storage place should be kept dry, cool and ventilated, avoiding direct sunlight and high temperature.

Polyvinyl alcohol (PVOH) resins and other additives are mixed, heated to a molten state and extruded through an extruder, which undergoes a cooling and curing process to achieve the desired physical and chemical properties, and finally cut and packaged.

PVOH 728F itself is a non-toxic, odorless, non-polluting, and environmentally friendly product. However, when using, appropriate protective equipment such as masks and gloves should be worn, and the operating instructions in the product manual should be followed. In addition, hazardous situations such as fire or explosion may occur under certain specific circumstances, such as exposure to high temperatures and sources of ignition, so ensure that the storage environment is away from sources of ignition and high-temperature areas.
