Water Soluble Capsules

In modern agricultural production, the efficient use of pesticides and environmental protection have always been a pair of conflicting goals that need balance. Traditional pesticide packaging, such as plastic bottles, glass bottles, or aluminum foil bags, is convenient for storage and transportation but difficult to recycle or degrade, creating a major challenge for rural environmental management. With China’s continuous efforts in “plastic pollution control” and “green agricultural development,” a new eco-friendly material is emerging — PVA pesticide water-soluble film.






I. A Small Film with a Big Green Mission
PVA (polyvinyl alcohol) is a degradable material with excellent performance. Pesticide capsules made with PVA water-soluble film not only provide moisture resistance, compression strength, and precise dosing, but also dissolve quickly in water, releasing accurate amounts of pesticide solution.

Compared with traditional packaging, PVA water-soluble film allows farmers to achieve “instant dissolution upon water contact, accurate and targeted application.” This minimizes direct contact with pesticides, reducing health risks, while also cutting waste and environmental pollution. More importantly, this material gradually decomposes into water and carbon dioxide under natural conditions, leaving no long-term contamination of the soil — making it a truly green and eco-friendly material.

II. Policy Support Driving Industry Upgrades
In recent years, the Chinese government has introduced a series of policies to promote the reduction and substitution of disposable plastics.

For example, the “Opinions on Further Strengthening Plastic Pollution Control” issued by the National Development and Reform Commission and the Ministry of Ecology and Environment explicitly call for the promotion of degradable materials. Similarly, the Ministry of Agriculture and Rural Affairs, in its “Guidance on the Recycling and Disposal of Fertilizer Packaging Waste,” stresses the gradual elimination of aluminum foil packaging and the exploration of water-soluble polymer materials.

These policies have created favorable conditions for the promotion of PVA pesticide water-soluble film, while also accelerating the replacement of traditional packaging materials across the industry.

III. Technological Leadership and Wide Applications
Enterprises such as Foshan Polyva Environmental Protection Materials Co., Ltd. are actively driving the industrialization and commercialization of PVA pesticide water-soluble films.
