Pre-Perforated Low-Melt EVA Roll Bags on Core | Rubber Batch Inclusion Film

Pre-Perforated Low-Melt EVA Roll Bags for Rubber Compounding

Direct-Feed Batch Inclusion Packaging for Tire & Rubber Engineers

• Complete Melting Range: 70°C – 90°C (158°F – 194°F).
• Instant Tear Perforation: No blades required, ensuring zero cross-contamination and safer shop floors.
• Dual Sequential Tracking: High-contrast QR codes and human-readable serial numbers for error-proof MES/ERP tracking.
• Zero Packaging Waste: The low-melt EVA bag dissolves completely into the rubber matrix during Banbury mixing.

The Shop Floor Reality: Overcoming Rubber Batching Challenges

In modern tire manufacturing and custom rubber compounding, the chemical weighing and batching area remains one of the most error-prone and labor-intensive bottlenecks. Our low-melt EVA bags solve three critical industry challenges:

• Blade & Cutter Hazards: Using utility knives to open traditional packaging creates serious workplace safety risks and leads to stray knife blades contaminating compound batches.
• Traceability Gaps: Manual dosing of accelerators, antioxidants, and carbon black often lacks bag-level verification, leading to expensive scrap batches when incorrect chemicals are added.
• Dust & Material Waste: Handling loose powders or non-meltable bags generates packaging waste, heavy dust pollution, and secondary handling costs.

Core Product Features & Engineering

1. High-Precision Continuous Pre-Perforation (Ultra-Easy Tear)

Our proprietary inline micro-perforation technology creates uniform, tear-resistant dotted lines across the EVA roll film.

• Operator Friendly: Separate individual bags with a gentle tug — no scissors, utility knives, or mechanical cutters required.
• Enhanced Equipment Safety: Completely removes sharp objects from the mixing room, protecting workers and preventing metal debris from damaging internal mixers.

2. Industry 4.0 Dual-Track Traceability

Every single bag segment is printed with high-density, solvent-resistant inks designed to survive harsh industrial environments.

• Optical QR Scanning: Fully compatible with hand-held scanners and industrial camera vision systems. Seamlessly links ingredient weight and chemical type to your plant’s MES/ERP system prior to mixing.
• Human-Readable Serial Numbers: Clear, bold sequential numbering printed parallel to the QR code allows operators to perform instant visual double-checks.

3. Precision Low-Melt Formulation

Manufactured using premium EVA (Ethylene Vinyl Acetate) resins with precise Vinyl Acetate (VA) content tuning.

• Total Dispersion: Fully softens and homogenizes into the rubber compound during early mixing stages inside Banbury, Intermix, or Kneader equipment.
• Zero Impact on Physical Properties: Does not alter Mooney viscosity, cure rate, tensile strength, or cross-linking density of tire tread and sidewall compounds.

4. Heavy-Duty Powder Containment & Anti-Tack Surface

• Puncture Resistance: Exceptional impact strength prevents bag ruptures when loaded with dense powders like carbon black, silica, sulfur, or sticky resins.
• Anti-Tack Finish: Specially treated outer surface prevents rolls from blocking or sticking together in humid, high-temperature storage conditions.

Technical Specifications & Parameters

Ideal Application Scenarios

Where this low-melt packaging solution delivers maximum ROI:

• Tire Manufacturing: Small chemical masterbatching (curing accelerators, sulfur, anti-degradants, coupling agents).
• Recovered Carbon Black (rCB) & Silica: Clean, dust-free dosing for recycled carbon black and white carbon black additives.
• Custom Rubber Compounding (CRM): Batch inclusion packaging for technical rubber goods, automotive seals, industrial hoses, and anti-vibration parts.

Sustainability & European Compliance (PPWR)

Under the European Union's Packaging and Packaging Waste Regulation (PPWR) and global corporate ESG goals, industrial waste reduction is mandatory. Our bags help you achieve zero-waste mandates:

• 100% In-Process Consumption: Because the bag becomes an integral part of the final rubber recipe, zero packaging enters municipal waste streams or landfills.
• Reduced Carbon Footprint: Eliminates the energy and logistics costs associated with recycling or disposing of contaminated plastic film bags.
• ISCC PLUS Ready: Available with certified bio-based or circular EVA raw materials upon request for full lifecycle sustainability compliance.

FAQ

Q1: Will the EVA low-melt bag alter the physical properties or Mooney viscosity of my rubber compound?
A: No. Our bags are formulated with precise VA (Vinyl Acetate) content that completely homogenizes into the polymer matrix during the early mixing phase. Extensive testing with major tire manufacturers proves zero negative impact on cure rate, tensile strength, or cross-linking density.

Q2: What equipment is compatible with these pre-perforated roll bags?
A: They are fully compatible with automatic and semi-automatic weighing and batching lines, as well as manual shop floor dosing stations feeding Banbury mixers, Intermix kneaders, and open mills.

Q3: Can we customize the bag dimensions, thickness, and printing format?
A: Yes! We offer full OEM/ODM customization. You can specify bag width, length, thickness (ranging from 40 to 120 microns), and your exact ERP-compatible QR code format or sequential numbering.

Q4: How do I request evaluation samples for trial runs?
A: Simply contact our engineering team with your batch weight and melting temperature requirements. We provide free customized sample rolls for factory testing.
