EVA Packaging Film for Rubber Additives

Product Detail

Zonpak^TM EVA packaging film is specially designed for making little bags of rubber additives (e.g. 100g-5000g) with a form-fill-seal (FFS) bagging machine. Various rubber additives or chemicals (e.g. peptizer, anti-aging agent, curing agent, cure accelerator, rubber process oil) are commonly used in the rubber mixing process, and only little amounts of these materials are needed for each batch. So these little packages can help the material users increase work efficiency and avoid material waste. The film is made of EVA resin (copolymer of ethylene and vinyl acetate) which has a specific lower melting point and good compatibility with rubber or resin materials. So the bags together with the materials contained can be direct put into a mixer. The bags will melt and disperse into the rubber compound as a minor effective ingredient. Films with different melting points (65-110 degree Celsius) and thickness are available for different using conditions.
