Founded in 1997, Cinch Packaging Materials Co., Ltd/ Hongkong Cinch Packaging Materials Co., Ltd is an enterprise integrates research, development with production on PVOH/PVA/POVAL bags and various laminated packaging bags. Our company has advanced production equipment, perfect testing apparatus and quality assurance system. It has formed a variety of PVOH bag specifications, with modern workshop and a number of high-class automatically bag production line. We own advanced Japanese Fuji seven-color and eight-colour computerized high-speed gravure printing machine and automatic reloading high-speed laminating machine and various multi-functional packaging equipments. Cooperating with some experts in polymer research from key universities,after several years of running and integrating the most advanced production technology of PVOH film at home and abroad, we are producing PVOH film with international standard by blown extrusion.


Water-soluble PVOH film is made from water soluble polymers, having the appearance of a common plastic film. It has unique characteristic of completely dissolving in water at room temperature. The dissolved film disappears in water like sugar or coffee and the ingredients of the film change their appearance but remains present as dissolved solids in water . The rate of dissolution depends on agitation, water temperature, amount of water and thickness of the film. The PVOH has proved to be a revolutionary film with its multiple uses which has been acknowledged and hailed by not only satisfied users but also ENVIROMENTAL PROTECTION AGENCY (E.P.A.) strongly recommends in packing agriculture chemicals and pesticides in this water soluble film as it is completely biodegradable and safe for environment and with time to come the use of this film not only going to increase but also indispensable because of its biodegradability, eco-friendly with multiple uses. The major application of our products are water soluble laundry bag for infection control in hospitals,agrochemicals packaging, anti-static electronics packaging, daily chemicals packaging, mould releasing agent for prosthesis and artificial marble, etc.

Enterprise mission: Forge ahead on packaging industry. Establish top brand and contribute to the environment-friendly world.
