Blue Cloth Tape 180um 50m Roll for Battery Pack Bundling Reinforcement Battery pack PVC heat shrink seal tape

This heavy load blue cloth tape is the structural grade member of our battery pack tape range: instead of only closing a seam, it takes the load. At 180um with a thickened double thread woven backing, the tape is used to bundle modules, strap wrapped packs, secure heavy insulation stacks and reinforce corners where the pack is lifted, strapped or transported.

This tape is mainly used for sealing PVC heat shrink film.

• High load bearing: the 180um thickened cloth carries tension across the full tape width, holding module stacks and wrapped packs together without necking down.
• Thickened and widened: available in wide formats so one wrap can secure a full pack section, replacing multiple narrower strips and reducing labour time.
• High tack, firm grip: 15-22 N/25mm peel adhesion holds on PVC film, aluminium, painted steel and plastic shells, resisting vibration loosening in mobile packs.
• Temperature cycling stability: stable adhesion from -10 C to 90 C, so the strap does not creep in a hot container or slip in a cold store.
• Waterproof and moisture proof: the PVC laminated surface keeps water out and does not soften in humid conditions.
• Durable and tear resistant: double thread woven structure resists tearing and fraying at cut ends, keeping the bundle intact through handling.

• Bundling of cylindrical cell groups and prismatic modules before insertion into the pack frame.
• Strapping of wrapped packs during transport and warehousing to prevent film opening and module shift.
• Reinforcement of pack corners and lifting points on heavy ESS modules and larger power stations.
• Fixing of thick insulation stacks, thermal barriers and heavy foam blocks that must not slide.
• Colour coded strap marking for QC traceability of bundle and sealing stations.

• Load matched selection: we size cloth density and adhesive coat weight against the actual strap load and pack weight you handle, avoiding both under spec tape and overpriced heavy grades.
• Wide format capability: in house slitting up to 1040mm means one pass can supply the wide strap roll your bundling station needs.
• Consistent unwind: controlled coating keeps unwind force stable through the 50 metre roll, so manual bundling stays fast without tape snap.
• Sample before order: trial rolls in your working width, so you can validate load and adhesion on your own pack before scaling up.
