PVA Water-Soluble Film Packaging Machine: Stable Production of Water-Soluble Pods for Daily Chemical and Agrochemical Industries

PVA water-soluble film packaging machines are specialized equipment designed to process polyvinyl alcohol films into sealed, water-soluble pods, playing a pivotal role in promoting green packaging in the daily chemical and agrochemical industries. With precise control systems and customized molding technology, these machines ensure stable, high-efficiency production of water-soluble pods, addressing the core needs of leak prevention, uniform dosing and environmental protection, while adapting to the unique characteristics of different products in the two sectors.

In the daily chemical industry, PVA water-soluble film packaging machines are mainly used to produce single-dose pods such as laundry pods, detergent pods and bath salt pods, relying on mature negative pressure adsorption and heat-sealing technology to achieve stable production. The machine first uses negative pressure to adsorb flat PVA films into pre-designed pod molds, ensuring the film fits closely without wrinkles or breakage. Then, it precisely injects liquid or paste daily chemical products into the film cavities with an error of less than 1%, avoiding overflow and ensuring consistent dosage per pod. Finally, the upper and lower films are heat-sealed at a controlled temperature (120–150℃), with the sealing strength exceeding 200g/cm² to prevent leakage during storage and transportation. Its adjustable speed (30–120 pods per minute) and compatibility with cold-water soluble PVA films meet the large-scale production needs of daily chemical enterprises, while the pods’ residue-free solubility enhances user convenience.

For the agrochemical industry, the machines are customized to produce pesticide and fertilizer water-soluble pods, solving the problems of chemical leakage, inaccurate dosing and operator safety hazards. Considering that agrochemical products are corrosive and require precise solubility control, the machines adopt corrosion-resistant injection nozzles and mold materials to avoid equipment damage. They can also customize pod solubility by matching different hydrolysis degrees of PVA films, enabling the pods to dissolve at specific soil temperatures and release chemicals slowly, realizing precise dosing and reducing environmental pollution. The closed production process of the machine prevents operators from direct contact with harmful agrochemicals, improving production safety, while the biodegradable PVA pods decompose into carbon dioxide and water in soil, avoiding plastic pollution in agricultural production.
