It is common that dust of raw materials flies everywhere in the workshop of rubber and tyre plants, which causes harm to the workers' health and pollution to the production environment as well. To solve this problem, EVA batch inclusion bags are developed after lots of material analysing and experiments. The bags have particular low melting points and are specially designed for the compounding and mixing of rubber and plastic materials in industrial process. Workers can use these bags to pre-weigh and temporarily store the ingredients and additives. In the mixing process, the bags together with the materials contained can be direct put into a mixing machine as the quality of the final product will not be compromised. The using of the low melting batch inclusion bags largely improves the production environment, minimizes the worker exposure to hazardous materials, makes the weighing of the materials easier and increases the production efficiency.


  • 1. The bags have low melting points: 70-110 degree celsius. Different melting points are available according to customers’ requirement. The bags can be direct put into a mill or mixer due to its good meltability and dispersity in rubber and plastic.

  • 2. The bags have good tensile strength, impact strength, puncture resistance, flexibility, and rubber-like elasticity.


  • 3. The bags have excellent chemical stability, no toxicity, good environmental stress cracking resistance, weather resistance and compatibility with the rubber materials. Decomposition products of the bag can be compatibly blended with natural rubber, styrene butadiene rubber (SBR), butadiene rubber (BR), solution polymerized butadiene styrene rubber (SSBR), polyisoprene rubber and high styrene resin, without affecting the physical and chemical properties of the rubber, and it can be used as an active ingredient of the rubber formula, reducing the production cost and avoiding packing waste.

  • Applications:

  • These bags are mainly used for packaging various chemical materials and reagents (e.g. white black carbon, black carbon, anti-aging agent, accelerator, sulphur and aromatic hydrocarbon oil) in the rubber industry (tire, hose, tape, shoes), plastic processing industry (PVC, plastic pipe and extrude ) and rubber and plastic additives industry.
