The quality review on PVA film is completed based on regular QC evaluation, or depending upon customer requirements. Samples are chosen and inspected for flaws randomly, according to those criteria and processes. For all those, Pre-Shipment Inspection is a significant measure in the quality management procedure and is the procedure for assessing the quality of PVA film until they're sent.

Today, Foshan Polyva Materials Co.,Ltd. has become one of the best manufacturers majoring in the development, design, and production of water soluble film suppliers. As one of Polyva's multiple product series, water soluble film series enjoy a relatively high recognition in the market. The product has the advantage of broad physical compatibility. It combines high tensile and tear strength with outstanding resistance to fatigue. Fast delivery can be guaranteed. Unlike single-use batteries, the product contains heavy metal elements that allow it to be recharged over and over. So people are free of dealing with useless batteries. Water- soluble packaging bags can be also applied as a pesticide packaging that greatly reduces the incidence of pesticide poisoning.

POLYVA has made a successful attempt to achieve the objective of becoming a global water soluble film provider.
