High Quality Manufacturing Of Water Soluble Bags

English

Formulation development

Since early 2005, our R&D team has focused on the R&D and market application of polyvinyl alcohol (PVA) water-soluble packaging film. We benchmarked and followed cutting-edge technology from North American counterparts, completed repeated pilot testing, and continuously upgraded our formula system.

Up to now, we have developed 6 mature formula systems covering over 20 film models:
15 types of low-temperature water-soluble PVA film
2 types of high-temperature water-soluble PVA film
5 types of medium-temperature water-soluble PVA film
In 2013, our team independently researched and developed high-speed automatic laundry pod packaging equipment and achieved mass production successfully.

Process development

We implement full-process verification from lab small trials → pilot scale-up → mass production line. All production procedures undergo full commissioning to guarantee stable, repeatable manufacturing performance for bulk orders.

Raw material control

We cooperate with top-tier certified raw material suppliers with stable supply chains. Every batch of raw materials undergoes incoming inspection to ensure consistent quality and eliminate raw material fluctuations.

Full-Link Process Control

Whole-process real-time monitoring covers mixing, film casting, forming, slitting, and finished product inspection. Standardized operating procedures reduce human error and stabilize film solubility, tensile strength and dimensional accuracy.

Standardized Storage Specification

Special constant temperature & humidity warehouses are equipped for PVA film storage. Complete storage guidelines prevent moisture absorption, deformation and film performance attenuation during stock.
