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, a new kind of bag with low melting point is specially designed for the compounding and mixing of rubber and plastic materials in industrial process. After analyzing of the raw materials used in the tyre and rubber factories and lots of experiments, the bags were developed and called batch inclusion bags. Workers can use the bags to pre-weigh and temporarily store the ingredients and additives. In the mixing process, the bags together with the materials can be direct put into a mixing machine as the quality of the final product will not be compromised. The use of the low melting batch inclusion bag largely improves the production environment, minimizes the worker exposure to hazardous materials, makes the weighing of the materials easier and increases the production efficiency.
The main applications and properties of the product are as follows:
The bags have low melting points: 70-115. Different melting points are available according to customers requirement. The bags can be direct put into a mill or mixer due to its good solubility and dispersity in rubber and plastic.
The bags have good tensile strength, impact strength, puncture resistance, flexibility, and rubber-like elasticity.
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.
The 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.
Low Melt EVA 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 machine, rubber chemical manufacturers can make big packages of 5kg-25kg. Using the bag can avoid the fly loss of the material when packing and there is no need to seal, so it largely improves the packaging efficiency. The bags are made from EVA (copolymer of ethylene and vinyl acetate) which has a lower melting point and is highly compatible with rubber, so the bags together with the contained materials can be direct put into a mixer, and the bags can fully disperse in the rubber or plastic as an effective ingredient. Bags with different melting points are available for different application conditions. With standard packages and no need to unpack before using the materials, the low melt valve bags also facilitate the work of the material users. Side gusset and block bottom forms are available types. Size, thickness, color, embossing and printing can be custom made according to customers specific requirement.
EVA Rubber Bags use a variety of plastic resins and a variety of additives blended together to change the plastic properties, to obtain new functional polymer materials.This new material through the extruder blown film having a low melting point, can be blended with the rubber-modified characteristics, and can be used as an active ingredient of rubber products.The product has good tensile strength, impact strength, puncture resistance, weather resistance, flexibility, and rubber-like elasticity.Mainly used in the batch processes of rubber industry, packaging of various chemicals needed for mixing ingredients (such as or oil, silica, carbon black, antioxidants, accelerators and a variety of small materials, etc.), putting into the mixing tank with the packaged ingredients directly , (no need to remove the bags) has no effect on rubber products (melt in rubber directly ).The use of such bags can play a role as follows: Packaging convenient, accurate measurement, reduce environmental pollution, reduce injury to staff. EVA Rubber Bags' applicability: This product is mainly used in the tire industry, hose tape industry, shoes of all kinds of chemical raw materials, loading chemicals, such as: this product can put into mixing equipment with raw material together,such as mixer or mill the machine, mixed with rubber, together raw material melting with Natural rubber, styrene butadiene rubber, butadiene rubber, SSBR and other products,does not affect the quality of rubber products.
Low Melt EVA Batch Inclusion Bags are specially designed industrial packaging bags for rubber ingredients and additives used in the rubber compounding process. As the material of the bags has good compatibility with natural and synthetic rubber, these bags of ingredients can be direct put into a mixer, and the bags will melt and fully disperse in the rubber as an effective ingredient. Main benefits of ZonpakTM Batch Inclusion Bags: Facilitate pre-weighing and handling of the materials. Assure accurate dosage of ingredients, improve batch to batch uniformity. Reduce spill losses, prevent material waste. Reduce dust fly, provide cleaner work environment. Improve the process efficiency, lower the comprehensive cost. Bags with different melting point (from 70 to 115 degree Celsius) are available for different rubber mixing conditions. Size and color can be custom made according to the customers specific application requirement.
