Factory Supply - Batch Inclusion Valve Bags – Zonpak

Zonpak^TM batch inclusion valve bags are specially designed for packaging rubber additives and other plastic materials in form of powder and granule. With the low melt valve bag and automatic filling machines, rubber additives manufacturers can make product packages of 5kg-25kg. Using the bags can eliminate the fly loss of the material when filling, and there is no need for sealing, so it can largely improve the packaging efficiency.

The bags are made from EVA resin and featured with specific low melting point and excellent compatibility with rubber, so the bags together with the contained materials can be direct put into a mixer, and the bags can fully disperse into the rubber or plastic as a minor ingredient. Different melting points (65-110 deg. C) are available for different application conditions. With uniform packages (5kg, 10kg, 25kg) and no need to unpack before using the materials, the low melt valve bags facilitate the work of the material users as well.

Side gusset and block bottom forms are available. Bag size, thickness, color, embossing, venting and printing can be customized according to customers’ specific requirement.
