Hot melt adhesive material selection background
Technical Material Selection Guide

Hot Melt Adhesive Material Selection Guide

Compare hot melt adhesive film, hot melt adhesive web and functional dot-film structures by substrate, polymer family, processing requirements and end-use performance. Use this guide to narrow suitable bonding options for textiles, foam, leather, plastics, wood, metal and rubber.

The right adhesive should be selected from the complete material combination—not only the adhesive name or melting point.

Quick Guide to Hot Melt Adhesive Film & Web

Start by deciding whether your application needs continuous adhesive coverage, an open web structure, or controlled dot coverage.

Three Product Forms

Four-Step Core Selection Method

1

Identify Both Substrates

Record the first and second materials. Fabric-to-foam, fabric-to-metal and plastic-to-metal constructions can require different adhesive behavior.

2

Check End-Use Requirements

Consider flexibility, washing, temperature resistance, breathability, waterproofing, appearance and aging requirements.

3

Check Processing Limits

Confirm the substrate's temperature limit, machine type, pressure, dwell time and line speed.

4

Test the Actual Materials

Use specifications to narrow the starting grade, then confirm bonding with the real substrates before mass production.

Need to Compare Polymer Families?

Polymer chemistry and adhesive form are separate decisions. TPU, PA, PES, TPE, PO/EAA and EVA can behave differently depending on the substrates and end-use requirements.

Material Selection Notes

1

Surface Treatment

Low-surface-energy plastics and other difficult surfaces may require corona, plasma, primer or another preparation method. Surface treatment should be evaluated with the actual substrate.

2

Processing Conditions

Melting range and lamination temperature are not the same. Actual processing also depends on thickness, line speed, pressure, dwell time and equipment.

3

Adhesive Weight & Thickness

More adhesive is not automatically better. Film thickness or web gsm should match the surface structure and required bond.

4

Small-Batch Validation

Trial bonding should be completed before mass production to confirm adhesion and end-use performance.

5

Finished-Product Testing

Washing, aging, temperature, breathability and other performance requirements should be checked on the finished laminate when relevant.

6

Custom Evaluation

If a standard product does not fit the construction, send both substrates and the process conditions so we can evaluate a more suitable starting option.

TPU web Grade dependent Flexible textile applications
EVA web Grade dependent Selected general-purpose applications

Functional Dot Film

Dot-pattern adhesive structures can be adjusted by application requirements such as adhesive coverage, flexibility, waterproofing and finished-laminate breathability.

Final pattern, adhesive weight and processing conditions should be validated using the actual textile construction.

Material Selection Decision Flow

Step 1: Identify both substrates

Start with the first and second materials rather than choosing only from the adhesive polymer name.

Step 2: Check whether flexibility or stretch is required

Flexible and elastic structures usually need an adhesive that does not unnecessarily restrict the movement of the finished laminate.

Step 3: Decide between film, web or patterned adhesive

Use film when continuous coverage is required. Evaluate web when the laminate benefits from a more open adhesive structure. Use patterned systems where controlled coverage is part of the functional requirement.

Step 4: Check temperature and washing requirements

Compare the adhesive grade with the substrate's heat tolerance and the finished-product washing, dry-cleaning or service-temperature requirements.

Step 5: Validate the production process

Confirm temperature, pressure, dwell time or line speed using the customer's actual substrates and production equipment.

Real Bonding Tests & Application Evidence

Material guides are useful for narrowing the starting point, but real substrates provide better evidence for final selection.

Hot Melt Adhesive Material Selection FAQ

How do I quickly determine which hot melt adhesive is suitable for my material?
Start with the first substrate and second substrate. Then identify the required flexibility, washing or temperature resistance, adhesive form and available lamination conditions. Use these factors to narrow the product family before testing the actual materials.
What is the difference between hot melt adhesive film and hot melt adhesive web?
Hot melt adhesive film creates a continuous adhesive layer, while adhesive web has an open fibrous structure with spaces between adhesive strands. The suitable form depends on the substrates and finished-product requirements.
Which hot melt adhesive can bond PP or PE?
PP and PE are low-surface-energy plastics, so PO/EAA or another adhesive designed for low-energy surfaces is often worth evaluating. Surface treatment can also change the result. The second substrate still needs to be considered.
Is melting point the same as lamination temperature?
No. Melting range describes a material property. Actual lamination temperature also depends on the substrates, material thickness, equipment, pressure, dwell time and line speed.
Should I choose the thinnest film or lowest web gsm?
Not automatically. The adhesive amount must be sufficient for the surface structure and required bond. For example, a porous or pile fabric may need more adhesive at the interface than a flatter nonwoven structure.
What information should I provide for an adhesive recommendation?
Send the first substrate, second substrate, final application, current adhesive if any, available temperature, machine type, pressure, dwell time or line speed, required end-use performance and estimated production volume.
