Hot Melt Adhesive Film for Plastic-to-Metal Bonding
Hot Melt Adhesive Film for Plastic-to-Metal Bonding
Hot melt adhesive film for plastic-to-metal bonding is a heat-activated thermoplastic dry-film bonding layer for joining ABS, PC, PET fiberglass board and selected plastic structures with aluminum or metal parts.
- Representative grade directions include ZF-4200 for listed plastic-metal structures and ZF-1682 for special metal or lower-temperature directions.
- Supports clean dry bonding without liquid adhesive coating in flat lamination, insert bonding, labels, trims and industrial component assembly.
- Helps define plastic-side and metal-side material stacks clearly for sample matching and RFQ review.

Product Fit
This product is for manufacturers and converters that need a clean adhesive layer between plastic and metal components. As a plastic-to-metal adhesive film and metal bonding adhesive film, it works as a dry, heat-activated thermoplastic bonding layer for flat lamination, insert bonding, panel parts, trims and compact industrial assemblies.
The page is built around verified VELNORA grade directions instead of a generic all-plastic claim. ZF-4200 covers listed ABS, PC, PET fiberglass board and metal-related structures, while ZF-1682 supports special metal and lower-temperature directions.
Typical Applications / Component Uses
| Application / Component | Typical Use Position | Buyer Value |
|---|---|---|
| Electronic accessory parts | Plastic housing, insert, nameplate or support layer bonded to metal | A controlled dry adhesive layer supports compact assemblies and neat edge handling. |
| Decorative and functional panels | Plastic sheet or PET fiberglass board laminated to aluminum or selected metal backing | Sheet or roll film gives even adhesive placement across flat bonding areas. |
| Labels, badges and trim parts | Die-cut adhesive positioned between a plastic face layer and metal part | Converted pieces support repeatable placement for shaped local bonding. |
| Industrial composite components | Plastic board or molded part bonded to a metal insert, sheet or support | Grade direction and supply form can be matched to the component structure. |
Typical Bonding Structures
The bonding structure should be defined as a material stack, with the adhesive film placed between the plastic side and the metal side.
| Bonding Structure | Application Position | Buyer Value |
|---|---|---|
| ABS plastic -> ZF-4200 TPU + resin hot melt adhesive film -> aluminum or selected metal part | Plastic housing, panel, insert and nameplate structures | Gives buyers a direct plastic-to-metal stack for listed ABS and metal-related structures. |
| PC part or sheet -> ZF-4200 TPU + resin hot melt adhesive film -> aluminum or selected metal support | Electronic accessory parts and flat industrial laminates | Supports heat-activated dry-film placement between PC surfaces and metal supports. |
| PET fiberglass board -> ZF-4200 TPU + resin hot melt adhesive film -> metal insert or metal sheet | Composite boards, support plates and functional panel parts | Keeps the adhesive layer defined inside rigid or semi-rigid composite structures. |
| Special low-energy surface -> ZF-1682 modified TPU hot melt adhesive film -> special metal surface | Special-surface or lower-temperature bonding direction | Routes special surfaces toward a modified TPU grade direction instead of a generic all-plastic claim. |
Technical & Processing Reference
Product Evidence Status: A. The following representative grades and process references come from approved VELNORA model evidence. Bonding strength and undefined service-temperature values are intentionally not published here.
| Representative Grade | Material | Melting Point | Width | Shore Hardness | Listed Processing Reference |
|---|---|---|---|---|---|
| ZF-4200 | TPU + resin | 100 C | 24 in | 70A | 120-150 C, 0.1-0.4 MPa, 5-15 s |
| ZF-1682 | Modified TPU | 65 C | 54 in | 60A | 90-110 C, 0.1-0.4 MPa, 5-12 s |
Film / Grade Matching
Grade and thickness direction should be matched to the actual substrate pair, metal finish, bonding area and converting method. This keeps ABS, PC and PET fiberglass board structures separate from PP, PE, TPO and other low-surface-energy plastic projects.
| Please Provide | How It Guides Film / Grade Matching |
|---|---|
| Plastic name and form | Separates ABS, PC and PET fiberglass board structures from PP, PE, TPO or other low-surface-energy projects. |
| Metal type and surface finish | Helps match the film direction to aluminum, selected metal, coated, anodized or painted surfaces. |
| Bonding area and part size | Guides roll, sheet, slit-roll or die-cut supply and adhesive placement. |
| Lamination or heat-press setup | Connects the selected grade with thermal activation, pressure and dwell-time handling. |
| Liner and converting preference | Supports release-paper handling, sheet preparation, slit width or die-cut piece supply. |
Processing & Sample Evaluation
Use a stable lamination or heat-press process with clean plastic and metal surfaces, controlled film placement and consistent cooling after thermal activation. VELNORA can prepare a representative film direction according to the plastic identity, metal finish, bonding area and equipment setup.
Custom Supply & Quality Support
Supply options include full rolls, slit rolls, sheets and die-cut pieces. Quality support focuses on film thickness, roll width, roll appearance, liner release, sheet flatness, die-cut edge quality, adhesive-layer consistency and packed roll condition.
FAQ
Which plastic-to-metal structures does this page cover?
The main listed structures are ABS, PC and PET fiberglass board bonded with aluminum or selected metal parts, inserts, sheets and supports.
Why are ZF-4200 and ZF-1682 shown here?
ZF-4200 is the representative TPU + resin direction for listed plastic-metal bonding structures. ZF-1682 is the modified TPU direction for special metal surfaces and lower-temperature requirements.
Are PP, PE and TPO handled the same way as ABS or PC?
No. PP, PE and TPO are low-surface-energy plastics and should be routed toward PO or modified-grade selection instead of being treated as the same ABS or PC structure.
What information helps VELNORA prepare a sample direction?
Send the plastic type, metal finish, bonding area, part dimensions, supply form, liner preference, equipment condition and estimated quantity for quotation preparation.
