Core Benefits of Our EVA low Melting Bags
1. Residue-Free
No need for unpacking; directly add sealed bags to internal mixers, kneaders and open mills. The bag melts rapidly under working temperature and blends evenly with rubber materials without separation, never affecting vulcanization, hardness and other mechanical properties of finished products.
2. Customizable Melting Point
Available melting points: 65℃, 72℃, 85℃, 90℃, 95℃ to fit diverse production processes. All items are strictly tested to avoid accidental melting during storage and transportation.
3. Dust-Free & Eco-Friendly
Fully sealed design eliminates dust leakage for cleaner Rubber Mixing & Compounding workshops. The bag melts completely with materials, producing zero waste packaging to save disposal costs.
4. Cost & Quality Optimization
Simplify feeding procedures to cut labor costs; sealed packaging reduces material loss and ensures accurate batching, effectively stabilizing product quality and lowering defective rates.
5. Strong Versatility
Tear-resistant and leakproof with uniform thickness. We provide customized sizes and thicknesses to match small-batch additives and large-batch raw materials for all rubber production lines.

Application Scenarios
Our EVA low melting point batch bags cover mainstream sectors across the rubber mixing industry, including tire manufacturing, rubber hoses & belts, rubber footwear, and other rubber compounding fields. The bags are suitable for packaging all kinds of rubber compounding ingredients, such as powder additives, oil agents, carbon black, silica, anti-aging agents, accelerators and various small auxiliary materials.
How to Use
Put the pre-packaged chemical ingredients directly into the internal mixer or other mixing equipment as a whole. There is no need to unpack or take out raw materials. The melted EVA material has zero negative impact on the formula and overall quality of rubber finished products.
Additional Product Advantages
-
Eco-Friendly Performance: Adopt sealed feeding design to effectively suppress dust flying during material feeding, reduce workshop air pollution, and create a cleaner and healthier production environment that meets international environmental protection standards.
-
Accurate Batching Measurement: Support customized fixed-quantity packaging. It avoids material loss caused by dust leakage, ensures precise ingredient measurement, meanwhile lowers occupational health risks to on-site operators.
-
Excellent Material Compatibility: The EVA bag can be perfectly fused with multiple mainstream rubber materials, including natural rubber, styrene-butadiene rubber, polybutadiene rubber and solution-polymerized styrene-butadiene rubber. It will not damage rubber vulcanization performance or change product physical attributes.

Precautions
-
Storage Environment: Store the EVA batch bags in a dry, cool and ventilated warehouse, keep away from direct sunlight, high-temperature heat sources and corrosive chemicals. The storage ambient temperature should be kept below 45℃ to prevent premature softening or melting.
-
Operating Temperature: Please select matching melting-point bags according to the actual working temperature of your mixing equipment. Do not use low-melting bags in ultra-high-temperature mixing environments to avoid early melting and material leakage before feeding.
-
Packaging Restriction: Do not overfill the bag during ingredient packaging. Reserve proper internal space to prevent the bag from rupturing caused by thermal expansion after putting into the mixer.
-
Feeding Specification: Avoid sharp hard objects piercing the bag during transportation and feeding. It is prohibited to use damaged bags to load powdery and liquid additives.
-
Applicable Scope: This product is only used for rubber internal mixing and compounding procedures. It is exclusively suitable for specified rubber materials and banned for other industrial scenarios without prior testing.
