Product introduction

The company's vacuum preloading film produced by blow molding is a new generation of products developed on the bais of the original technology ,and the new generation  vacuum preloading film is made of GFZ-7626 polymer materia, produced by unique formula and advanced technology, which not only enhances the tensile strength and toughness, but also reduces the shrinkage rate after the vacuum pre-pressing film is stretched (ie, the resilience rate).The new product has a tighter molecular stucture and a smaller premeability coefficient. The shrinkage of the convention vacuum preloading film is generally 2-3%, and the shrinkage of the improved new-generation vacuum preloading film is only 0.2-0.5%. special anti-aging agent is added to  the vacuum preloading film to shield 80-90% of the ultraviolet light in the sunlight, which greatly improves the anti-aging performance of the vacuum film and prolongs the service life. It is a ideal sealing material for vacuum preloading project.

0.2-0.5% > 2-3%
the shrinkage of the improved new-generation vacuum preloading film is only 0.2-0.5%
80-90%
the vacuum preloading film can shield 80-90% of the ultraviolet light in the sunlight
Performance features

As the company's leading products, annual production quantity of PVC vacuum preloading film reaches more than 10000. PVC vacuum preloading film adopts unique process formula, absorbs domestic and abroad advanced technology and is the only professional product that adopts digital control technology for production and processing in the same industry in China. The indicators have been tested by the National Plastic Products Quality Supervision Center and both exceeded the ministry's excellent standards.
