EVA Low‑Melt Direct‑Feed Bags, For Rubber Compounding · Hot Melt Coatings · Road Marking Paint

Product Features:

1. Precise Low Melting Point: 60°C–90-100°C

• Stable and controllable melting temperature, suitable for standard rubber mixing, hot melt systems, and road marking paint production.
• Melts uniformly without agglomeration, fish eyes, or undissolved spots.
• Fully compatible with your formula; does not affect physical properties, color, or curing performance.
• Melting point can be fine‑tuned according to your process temperature requirements.

2. Direct‑Feed Design — No Unpacking Needed

• Throw the entire sealed bag directly into the internal mixer, open mill, or melting tank.
• Eliminates manual bag cutting, unpacking, and scraping, greatly reducing labor intensity.
• Avoids material spilling and waste caused by manual operation.
• Suitable for automated feeding lines to improve production continuity.

3. Thickness: 50mic–80mic, Customizable

• Standard thickness: 50–80 microns, balancing strength and melting speed.
• Good tensile strength, tear resistance, and drop resistance, not easy to break during handling, stacking, and transportation.
• Flexible film structure ensures fast melting while maintaining good packaging performance.
• Can be customized to thinner or thicker specifications based on weight and usage scenarios.

4. Capacity Range: 5kg–20kg

• Available in standard weights: 5kg, 10kg, 15kg, 20kg to meet different dosing and batch requirements.
• Pre‑weighed packaging ensures accurate dosing and improves batch‑to‑batch consistency.
• Suitable for powder, granular, paste, and small additive packaging.
• Bag size and structure can be customized for automatic filling machines.

5. Dust‑Free & Clean Production

• Completely seals chemical powders, carbon black, pigments, additives, and fillers.
• Prevents dust flying during feeding, protecting workers’ health and workshop cleanliness.
• Reduces equipment fouling and daily cleaning workload.
• Helps meet environmental, health, and safety (EHS) standards.

6. Full Compatibility & No Residue

• The EVA bag material melts completely and integrates into the final product.
• No residual plastic film, no impurities, no blockages in filters or pipelines.
• Does not affect viscosity, adhesion, flexibility, or durability of coatings and rubber compounds.
• Safe for use in high‑performance rubber products and road marking paint.

7. Flexible Customization

• Customizable melting point, thickness, size, and loading weight.
• Custom colors: transparent, white, yellow, blue, etc., for material identification.
• Support printed logo, product name, batch number, barcode, etc.
• Can be made into flat bags, gusseted bags, or valve bags according to filling needs.
