Low-Melting Batch Inclusion bags for Chemical Addition in Rubbers


 eva bags

 Product Description



Rubber compatible bags are specially grade polymer bags used for the addition of solid or liquid chemicals into the rubber during its processing in banbury or kneaders.

Unlike the usual Polyethylene bags,these special grade polymer used for the manufacture of these bags is highly compatible with rubber and mixes with rubber at normal processing temperatures.Hence this allow for the direct additionj of the chemicals included in the bag into the rubber processing sysytems along with te bag which mixes with rubber.

Start of Melting 70°
End of Melting 86°
Composition 100% Ethyl Vinyl Acetate Polymer
Thickness 25 to 200 microns
Color As Required
Size 2*2 to 50*50


  • IMIX Eva Bags form a highly compatible blend with rubber during the addition of chemicals.
  • Allows for exact dosing of the solid and liquid chemicals into the rubber.
  • The bags can be preweighed by quality department instead of production staff to have exact ratio of the different chemicals.
  • Results in a consistent batch of material time after time due to exact dosing of the chemicals.
  • Reduces the flyloss of the chemicals into the atmosphere.
  • Provides better work environment for the employees
  • Saves money by preventive fly loss.

Applications & Uses:

  • Can be used to wrap raw rubber. EVA bags when wrapped on raw rubber prevent dust settlement on rubber. This need not be taken off before usage of rubber.
  • EVA film can be provided on rolls for automatic weighmetric form fill seal machines to make preweighed chemical sachets and pouches.
  • EVA bags can be used as liners in chemical HDPE bags where the chemical need not be emptied out and can be thrown with the EVA liner into banbury or other processing equipment.

I-MIX EVA Compared to Normal EVA:

  • I-MIX EVA contains 100% EVA and 0% LDPE. This is owing to the patented process of manufacturing I-MIX EVA which has the capability of extruding 100% EVA without the need of LDPE/LLDPE to strengthen the film.
  • This provides a much faster and superior compatibilisation of I-MIX EVA compared to the ordinary EVA films/bags available in the market.
