In the demanding world of plastic fabrication, surface integrity is non-negotiable. Donlee offers a specialized thermoforming film designed to follow your plastic shapes flawlessly during the thermoforming and vacuum-forming processes.
Whether your molding process operates between 90°C and 230°C for durations ranging from seconds to 15 minutes, our protective solution adheres optimally to plastic surfaces. As the shape changes, the film follows—maintaining a snug fit without lifting or tearing.
This specialty protective film is a premier product from Donlee, a globally recognized thermoforming film manufacturer. Engineered specifically for hot-working conditions, it acts as a robust shield for delicate surfaces such as PC, PMMA, ABS, and PS plastics. Our films protect these substrates from unexpected defects, ensuring that the high-value finish remains intact from the in-plant process until it reaches the end consumer.
Key technical characteristics of this series include:
Co-extruded construction: A multi-layer design for superior durability.
Low-tack gel technology: Ensures a transparent, clear view for quality inspection.
Adjustable thickness: Tailored to fit various forming scenarios, from deep draws to sharp bends.
Residue-free removal: Despite withstanding heavy thermoforming, the film remains easy to remove without damaging the underlying plastic.
As one of the most trusted thermoforming film suppliers, Donlee provides distinct advantages to streamline your production:
Extreme Temperature Resistance: Stable performance at temperatures up to 230°C for 15 minutes.
Scalable Specifications: Available in widths up to 2600mm to accommodate large-scale industrial sheets.

Donlee stands out among thermoforming film suppliers by offering not just a product, but a partnership in quality control. We welcome you to enquire for more details about our thermoforming film technology; our team is ready to provide the technical support your project requires.
Thermoforming is a process that demands precision. Production engineers know the risks of using a generic film—fused sheets, ghosting marks, and bubbling during the deep-draw molding process can wreak havoc on the quality of finished products. Once the plastic reaches temperatures exceeding 150°C (302°F) during forming, ordinary polyethylene (PE) films fail due to low thermal tolerance and poor malleability.
Heat-stabilized adhesion is critical. Traditional films often shrink, thin out, or even adhere to thermoplastic sheets during heating, leading to defects that affect part performance and aesthetic quality.
At Donlee, our thermoforming films are engineered to overcome these challenges. By maintaining their elongation properties, the films stretch uniformly with substrates during the molding process, ensuring a perfect fit without compromising on quality.
Different industries demand different substrates, and Donlee's thermoforming films are compatible with an extensive range of materials. Whether you're molding automotive components, medical-grade packaging, or aerospace interior panels, our films provide optimal surface protection.
| Substrate | Use Case | Film Features |
|---|---|---|
| ABS (Acrylonitrile Butadiene Styrene) | Automotive interiors, electronics housings | High-temperature resistance, no ghosting |
| PETG & Polycarbonate (PC) | Medical packaging, optical clarity applications | Anti-static, ideal for clean-room environments |
| High-Impact Polystyrene (HIPS) | Consumer products, food packaging | Uniform adhesion, no residue post-forming |
| PMMA (Acrylic) | Display panels, signage | UV-stabilized, scratch-resistant surfaces |
Our films are designed with a precision-engineered heat-stabilized PE base, complemented by a specialized heat-resistant adhesive. The balance of surface tension (dyne levels) ensures the adhesive bonds effectively to plastics during molding but can be peeled cleanly without leaving residues or ghosting. This unique formulation prevents contamination and maintains the integrity of high-value molded components.
When sourcing a thermoforming film supplier, you need a partner who can deliver consistent quality, technical expertise, and process reliability. That's the Donlee promise.
