I. Concept and Fundamental Properties
EVA low-melting-point feeding bags are industrial consumables made of ethylene-vinyl acetate copolymer (EVA). Their melting point can be adjusted to a range of 65–110°C via formula modification. Unlike ordinary packaging bags, they can be fed entirely into rubber mixing and plastic compounding equipment. At high temperatures, the bags fully fuse with rubber and plastic materials without leaving residues, and will not impair the plasticization or vulcanization performance of finished products.
Boasting leak-proof sealing, puncture resistance, eco-friendliness and non-toxicity, these bags are compatible with automated production lines. They effectively resolve prevalent industrial challenges including dust pollution during conventional feeding, material loss and inconsistent proportioning.
II. Core Application Scenarios
| Application Field | Applicable Working Conditions & Raw Materials | Core Advantages |
|---|---|---|
| Tires & Rubber Products | Feeding into internal mixers and kneaders; suitable for carbon black, vulcanizing agents, anti-aging agents and other rubber raw materials | Stabilizes rubber compound proportions, reduces product defects, and improves the consistency of overall rubber product quality |
| Modified Plastic New Materials | High-temperature compounding processes for plastic masterbatches, elastomers and composite materials | Melts completely without residues, preserves material purity and mechanical properties, and meets high-end modified production standards |
| Wire & Cable Industry | Production of auxiliary materials for cable insulation and sheath compounds | High cleanliness with zero impurities, ensuring compactness and service safety of cable rubber compounds |
| Dust-Free Workshops in Fine Chemical Industry | Closed feeding of various powders and chemical additives | Eliminates dust scattering, mitigates safety and occupational health hazards, and complies with strict clean production requirements |
III. Market Supply and Customization System
The market supply system is well-established, divided into standard stock products and fully customized products to accommodate procurement demands across diverse production scenarios.
- Standard Stock ProductsThe mainstream ready-made melting points available on the market are 72°C and 85°C, compatible with conventional mixing temperatures for most rubber and plastic manufacturing. Standard thicknesses and sizes are kept in stock, with flat-mouth feeding bags as the universal bag type. Featuring cost-effectiveness and instant availability, they suit regular mass production and quick material replenishment for small and medium-sized factories.
- Fully Customized ProductsComprehensive customization is available for high-end and special working conditions:
- Performance customization: Precisely adjust melting points between 65°C and 110°C; develop anti-static, anti-aging, highly transparent, high-cleanliness food-grade or chemical-grade formulas as required.
- Appearance & specification customization: Adjust bag thickness and dimensions; produce special bag styles such as valve-port and pointed-bottom bags; support multi-color printing of logos, batch numbers and formulation information to meet enterprises’ needs for refined production, brand traceability and strict dust-free workshop operation standards.
