Understanding Adhesive Film
Adhesive film is a thin, flexible material with an adhesive coating on one or both sides. Its primary function is to bond two surfaces together. The film itself can be made from various polymers, impacting its properties and applications. The adhesive can be pressure-sensitive, requiring only pressure for bonding, or heat-activated, like hot melt adhesive film, requiring heat for activation. The choice of base material and adhesive dictates the film’s overall performance.
Technical Features of Adhesive Films
The performance of adhesive films is determined by various factors. Key features include:
| Feature | Description |
|---|---|
| Base Material | The type of plastic film used (e.g., PET, PVC, PP, TPU, PA, PES, EVA). This affects flexibility, strength, and temperature resistance. |
| Adhesive Type | Pressure-sensitive, hot melt, or other specialized adhesives. This impacts bonding strength, tack, and application method. |
| Thickness | Measured in microns (µm) or millimeters (mm). Influences strength and flexibility. |
| Width | Varies depending on application needs. |
| Melting Point | For hot melt adhesives, the temperature at which the adhesive becomes liquid. |
| Adhesion Strength | The force required to separate the bonded surfaces. |
| Temperature Resistance | The film’s ability to withstand high or low temperatures without losing adhesion. |
| Water Resistance | The film’s ability to resist moisture and maintain adhesion in damp conditions. |
| Release Liner | A backing paper that protects the adhesive until application. |
Types of Adhesive Films
Various types of adhesive films exist, each tailored to specific applications. The selection depends on the materials being bonded, environmental conditions, and required bonding strength.
| Type | Base Material | Adhesive Type | Key Properties | Applications |
|---|---|---|---|---|
| TPU Hot Melt Adhesive Film | Thermoplastic Polyurethane | Hot Melt | High elasticity, washable, good adhesion | Clothing, footwear |
| PA Hot Melt Adhesive Film | Polyamide | Hot Melt | Good low-temperature resistance, washing resistance, strong bond | Fabric, leather, PVC bonding |
| PES Hot Melt Adhesive Film | Polyester | Hot Melt | Wide bonding range, good washing resistance | Clothing, electronics, shoe-making, construction |
| EVA Hot Melt Adhesive Film | Ethylene-vinyl acetate | Hot Melt | Fast curing, strong adhesion, environmentally friendly | Shoe industry, automotive industry, wallcovering |
| PO Hot Melt Adhesive Film | Polyolefin | Hot Melt | Good low and high-temperature resistance, strong adhesion | Metal, plastic, wood bonding |
| Self-adhesive Film (General) | PET, Vinyl, PP, etc. | Pressure-sensitive | Varies widely based on the base material and adhesive type | Diverse applications, including labeling and packaging |

FAQs
1. What is the difference between hot melt adhesive film and pressure-sensitive adhesive film?
Hot melt adhesive film requires heat to activate the adhesive, while pressure-sensitive adhesive film bonds upon application of pressure.
2. Which type of adhesive film is best for bonding fabrics?
TPU, PA, or PES hot melt adhesive films are often preferred for fabric bonding due to their flexibility and wash resistance.
3. How is the thickness of adhesive film measured?
Thickness is typically measured in microns (µm) or millimeters (mm).
4. What factors should be considered when selecting an adhesive film?
Consider the materials being bonded, environmental conditions, required bonding strength, temperature resistance, and water resistance.
5. What is the role of a release liner in adhesive film?
A release liner protects the adhesive from premature bonding until application.
