What Is Heat Transfer Release Film?

Heat transfer release film is a functional PET-based carrier film used in heat transfer printing processes. It allows printed ink layers to transfer smoothly onto plastic products such as buckets, containers, cups, and industrial packaging.

The release coating ensures:

Stable peeling performance

Excellent ink transfer

High-temperature resistance

Smooth printing operation

Strong compatibility with gravure printing

Production Process of PET Release Film

The production process of our PET release film follows standard professional procedures with imported Dow Corning silicone oil, and the detailed of our manufacturing steps are as follows:

productcate-1-1

Raw Film Inspection

Firstly, inspect the purchased original PET base film strictly. We conduct comprehensive quality checks on the film’s thickness, flatness, surface cleanliness and tension stability to ensure the raw material meets production standards and eliminate defective base films.

productcate-50-50

productcate-1-1

Surface Coating with Imported Silicone Oil

After passing the inspection, the qualified PET base film is sent to the coating machine. We adopt high-quality imported Dow Corning silicone oil as the release coating material, and uniformly coat the silicone oil on the single side of the PET base film through precise coating equipment to form an even release layer.

productcate-50-50

productcate-1-1

High-temperature Drying and Curing

The coated film is conveyed to the constant-temperature drying oven. Through scientific high-temperature baking, the silicone oil layer is fully dried and cross-linked and cured. This process removes residual solvent, ensures tight bonding of the silicone coating, and achieves stable and clean release performance.

productcate-1-1

Finishing and Winding

After complete drying and cooling, the finished release film is automatically wound into standard roll materials. Finally, we conduct random quality inspection on the finished products to guarantee stable overall film quality.

Product Categories

We have multiple advanced coating, slitting, and rewinding production lines, capable of precisely producing various roll and sheet materials with widths ranging from a minimum of 50mm to a maximum of 1650mm and grammage ranging from 30-230.

Heat Transfer Film for Paint Bucket Decoration

Customer Problem

A Southeast Asian packaging factory struggled with ink peeling, poor edge definition, and low transfer efficiency on PE/PP plastic buckets. Traditional films caused blurry logos and high rejection rates (12–18%), slowing mass production.

Solution

Weshare supplied 30μm PET release film with medium-release silicone coating, optimized for high-speed roll-to-roll transfer on curved plastic surfaces. The film delivers uniform ink laydown and clean cold peel after 150–160°C pressing.

Results

Rejection rate dropped from 15% to 2.8%

Transfer speed increased by 35%

Logo clarity & wash resistance passed 50+ wash cycles

Client expanded capacity to 50,000+ buckets/month

High-Speed Transfer Film for Chemical Pails

Customer Problem

A Chinese chemical pail manufacturer ran 60 m/min high-speed transfer lines but faced film tearing, inconsistent release, and web breakages. Downtime reached 8–10 hours/week, hurting profitability.

Solution

Weshare customized 75μm high-tensile PET release film (MD/TD ≥180 MPa) with high-temperature silicone coating (180°C stable). Precision thickness tolerance ±1μm and anti-static treatment ensured stable high-speed running.
