ZonpakTM EVA valve bags are a new type of packaging bags for rubber chemicals of powder or granule form e.g. carbon black, zinc oxide, silica, and calcium carbonate. The EVA valve bags are an ideal substitute for traditional kraft and PE heavy duty bags. The bags together with the materials contained can be direct put into a mixer because they can easily melt and fully disperse in the rubber compounds as a minor effective ingredient. Bags of different melting points are available for different using conditions.
With standard packages and no need for unpacking before using the materials, low melt valve bags can help make rubber and plastics mixing process easy, accurate and clean. Bag size, film thickness, color, embossing, venting and printing can all be customized as required.
Melting point available: 70 to 110 deg. C
Material: virgin EVA
Film thickness: 100-200 micron
Bag size: 5kg, 10kg, 20kg, 25kg
