Description
Custom Color Highland Barley Paper with Adhesive – High-Temp Resistant for 18650/21700/26650/32650 Batteries

When assembling cylindrical lithium battery packs (18650, 21700, 26650, 32650), reliable insulation, heat resistance, and easy assembly are non-negotiable—yet ordinary insulating papers often fall short on one or more fronts. Our Custom Color Highland Barley Paper solves this by blending three key strengths: extreme high-temperature resistance, strong pre-applied adhesive, and customizable colors for visual differentiation. Made from natural highland barley fiber, it’s not just an insulator—it’s a production-friendly solution that streamlines assembly, enhances safety, and lets you match your brand or module identification needs.

1. Core Advantages: Why This Highland Barley Paper Stands Out
Advantage Key Benefit for Battery Pack Manufacturers
Customizable Colors Available in red, blue, green, black, white, or your brand color—enables quick visual sorting (e.g., 区分 different battery modules or production batches) and reduces assembly errors.
180℃ High-Temp Resistance Withstands continuous use at 180℃ (short-term up to 220℃), outperforming standard PET or kraft paper (≤120℃) and avoiding insulation breakdown during battery charging/discharging.
Strong Adhesive Backing High-tack acrylic adhesive bonds firmly to battery casings; resists peeling even under vibration (ideal for e-scooters/EVs) or temperature cycles (-40℃ to 180℃).
Natural & Eco-Friendly Made from renewable highland barley fiber—halogen-free, non-toxic, and RoHS/REACH compliant, fitting green energy and consumer electronics standards.
Thin & Space-Saving 0.08mm–0.2mm thickness saves critical space in compact battery packs (e.g., power banks, laptop batteries) without compromising insulation performance.

3. Application Scenarios

This customizable highland barley paper is tailored for cylindrical battery packs across industries, where insulation safety and production efficiency matter:

  • Consumer Electronics: 18650 battery packs for power banks, laptops, and flashlights—thin design fits compact enclosures; custom colors help distinguish product lines.
  • Power Tools: 21700/26650 packs for cordless drills, grinders, and leaf blowers—high-temp resistance handles heavy-duty discharge heat; adhesive resists tool vibration.
  • Electric Mobility: 26650/32650 packs for e-scooters, electric bikes, and portable EV chargers—color-coding simplifies module maintenance; moisture resistance adapts to outdoor use.
  • Energy Storage: 32650 packs for home solar storage and industrial backup power—eco-friendly material aligns with green energy goals; reliable insulation ensures long-term safety.
4. Customization & Order Details
