China equally has the same needs for environmental-friendly packing as other foreign countries, therefore the domestic water-soluble film market is now emerging. According to the research, packing films account for 20% of the output of plastic products every year, amounting to about 309,000 tons.

The current blown film equipment will transform the P-PVA by thermoplastic processing directly into the film, commonly known as the dry method. This method produces water-soluble films with advantages like low energy consumption, high efficiency, wide application range, low cost and significant economic benefits, in other words, the water-soluble film is a very promising new material. According to the market demand for water-soluble films used for polyvinyl alcohol packing, there are three types as follows:
