Hot Melt Adhesive Film for Electronic Accessory Bonding & Lamination

Hot melt adhesive film is used as a dry bonding layer in electronic accessory structures such as phone and tablet covers, keyboard cases, audio wrapping, lining parts and local reinforcement components.

The film is positioned between the materials and activated by heat during lamination or assembly. For accessory products that combine PU leather, microfiber, textile, foam or decorative surface layers with ABS, PC or other support materials, the film provides controlled adhesive placement without applying liquid glue directly to the bonding area.

TPU is the primary VELNORA film direction for flexible electronic covers because it supports bending, folding and soft decorative structures. A lower-temperature TPU direction is especially useful when the outer surface is heat-sensitive or easy to mark during bonding.

This page focuses on consumer electronic accessories and soft-goods structures. Conductive films, thermal-management materials, PCB/FPC bonding and other internal electronic assembly adhesives belong to different product categories and should be evaluated separately.

Key Requirements for Electronic Accessory Bonding

  • 【Material Pair Compatibility】Match the adhesive film to both materials, such as PU leather, microfiber, textile or foam bonded to ABS, PC, backing board or another support layer.

  • 【Clean Appearance & Edge Stability】Protective covers and decorative electronic accessories need controlled adhesive placement around visible surfaces, folded areas, edges and corners where glue marks or edge lift can affect the finished product.

  • 【Heat-Sensitive Surface Compatibility】PU leather, microfiber, coated decorative layers and thin support materials can react differently to heat, so the film direction should match the surface appearance and temperature tolerance of the actual material stack.

  • 【Cutting, Liner & Positioning】Film width, thickness direction, release liner and supply format should match slitting, die cutting, positioning and heat-press assembly for small electronic accessory parts.

Electronic Accessory Bonding Applications

TPU hot melt adhesive film is used in electronic accessory structures where flexible surface materials, backing layers or local parts require controlled heat-activated bonding.
  • [Tablet & Keyboard Covers]For tablet keyboard covers, keyboard cases, lining layers, foam parts and support structures where flexible surface materials require clean lamination and accurate positioning.
  • [Phone & Folding Protective Covers]For PU leather or microfiber phone cases, folding protective covers and decorative outer layers bonded to backing or support materials.
  • [Audio Wrapping & Speaker Soft Goods]For speaker fabric, audio shell wrapping and decorative soft surfaces where a controlled adhesive layer is required between the textile or cover material and the supporting structure.

  • [Linings, Foam & Die-Cut Reinforcement Parts]For lining materials, foam layers, narrow adhesive strips, cover edges, corners and local reinforcement pieces that require cutting, positioning and converted-film handling.

TPU Adhesive Film Options for Electronic Accessory Production

  • Flexible TPU Adhesive Film——A practical starting direction for phone and tablet covers, keyboard cases, PU leather, microfiber and audio wrapping structures that require flexible dry-film bonding.

  • Low-Temperature TPU Film——For heat-sensitive electronic covers, decorative surfaces and thin materials where a lower-temperature bonding direction can help reduce surface marking or deformation.

  • TPU Film with Release Liner——For small parts, cover edges and converted components where release paper or release film supports cleaner cutting, positioning and heat-press handling.

  • Slit Roll, Sheet & Die-Cut TPU Formats——For narrow strips, custom cover shapes, corners, reinforcement pieces and production parts that require converted adhesive film rather than full-width roll material.

Film thickness direction, width, activation range, liner and supply format should be matched to the material stack, heat sensitivity, part geometry and available production process.
