Lithium Ion Battery Specialized Packaging and Bundling Tape with Customizable Width

Product Overview

This specialized lithium-ion battery packaging tape delivers exceptional mechanical reinforcement and electrical insulation for advanced energy storage manufacturing. Engineered with a premium-grade polyethylene terephthalate (PET) film backing and coated with a cross-linked acrylic pressure-sensitive adhesive, the tape provides robust adhesion without leaving residual contamination upon removal. It is formulated to withstand the rigorous thermal and chemical environments encountered during cell manufacturing, pack assembly, and module integration.

Designed specifically for cylindrical, prismatic, and pouch cell architectures, this bundling tape serves as a critical process and structural material. It secures electrode winding ends, bundles battery core groups, wraps busbars, and insulates internal metallic contacts against potential electrical shorting. With full compliance to strict environmental standards, including RoHS certification and halogen-free composition, the material ensures safe implementation across automotive EV battery lines, consumer electronics manufacturing, and stationary grid-scale storage systems.

Engineered for high-yield automated production lines and precision manual workstations, this tape delivers smooth unwinding characteristics and dimensional stability. Its exceptional dielectric breakdown resistance and high tensile strength prevent tearing under automated tensioning, offering cell designers and manufacturing engineers an uncompromising solution for structural integrity, process reliability, and long-term electrochemical safety.

Key Features

• Engineered PET Backing Structure: Built upon an advanced specialized polyester film substrate that exhibits superior tensile strength, dimensional stability, and puncture resistance during aggressive high-speed automated taping processes.
• High-Purity Acrylic Adhesive: Formulated with an ultra-stable, cross-linked acrylic pressure-sensitive adhesive system that guarantees aggressive initial tack, sustained peel adhesion, and zero adhesive transfer or chemical leaching.
• Superior Dielectric Breakdown Voltage: Provides electrical insulation ratings up to 5.0 kV, effectively preventing dielectric breakdown, internal arc propagation, and short circuits within tightly packed battery modules.
• Elevated Thermal and Environmental Resistance: Maintains structural integrity, peel strength, and mechanical elasticity under elevated temperature profiles and harsh chemical atmospheres common in modern cell formation and aging cycles.
• Halogen-Free and RoHS Compliant: Formulated to meet stringent global environmental directives, preventing toxic off-gassing and electrochemical contamination inside cleanroom manufacturing environments.
• Optimized Unwinding Dynamics: Calibrated release characteristics provide controlled, light-to-medium unwinding tension to eliminate tape elongation, wrinkles, or jamming on high-throughput robotic dispensing machinery.
• Residue-Free Clean Peel Performance: Engineered to strip cleanly during rework procedures or process transfers without marring delicate aluminum pouch foils or leaving adhesive residue on prismatic steel cans.
• Fully Customizable Width Configurations: Available in precision slit widths and standard master roll lengths to match exact automated feeder tooling specifications and manual assembly fixtures.

Applications

Technical Specifications

Note: The performance values listed above represent standard qualification test results and are provided for engineering reference purposes. Actual operational characteristics may vary slightly based on customer-specific application substrates, bonding temperatures, and processing environments.

Application & Processing Guidelines

1. Surface Preparation: Prior to application, ensure all target bonding substrates (such as bare aluminum, nickel-plated steel, copper foil, or pouch laminate) are clean, dry, and free from surface oils, dust, or solvent residues.
2. Application Pressure: Apply firm, uniform pressure across the tape surface using silicone application rollers or automated robotic tamp pads. Consistent mechanical pressure activates the acrylic adhesive matrix and maximizes surface contact area.
3. Dispensing & Tension Control: When integrating rolls into high-speed automatic wrapping machinery, maintain balanced web tension to prevent over-stretching the PET backing, ensuring optimal dimensional placement.
4. Storage Conditions: Store rolls in their original packaging in a climate-controlled warehouse at 20°C to 25°C (68°F to 77°F) and 50% relative humidity, away from direct sunlight and ultraviolet exposure, to guarantee maximum shelf life.
