Understanding Thickness (25 um to 150 um), Cold Peel vs Hot Peel, and Glossy vs Matte Finishes for Flawless Transfers
Product Overview
In the highly competitive world of custom apparel and heat transfer printing, the final quality is not just about the ink; it is defined by the release liner. The Heat Transfer PET Release Film is the critical carrier that holds the design through the printing process and dictates how it transfers onto the fabric. With varying thicknesses, peel types, and surface finishes, selecting the right technical parameters is essential for achieving vibrant, durable, and comfortable prints.
Key Technical Parameters to Consider
To ensure flawless transfers, buyers must specify three critical factors:
- Thickness Range (25 um to 150 um):
- Thinner films (25 um to 50 um) are highly flexible, providing a softer hand feel and are ideal for fine, intricate details.
- Thicker films (100 um to 150 um) offer superior mechanical strength, resisting curling and wrinkling during high-speed printing and cutting processes.
- Cold Peel vs Hot Peel:
- Cold Peel Release Film: The design must be allowed to cool completely before peeling. This prevents the ink from stretching, ensuring crisp edges and high-definition details.
- Hot Peel PET Film: Designed for high-efficiency production lines where the film is peeled immediately after pressing. It offers a smooth, matte finish and high production speeds.
- Glossy vs Matte Finishes:
- Glossy (High Gloss): Leaves a vibrant, reflective finish that makes colors pop.
- Matte: Provides a soft, non-reflective surface, reducing glare and offering a premium, fabric-like texture.
Applications Across Industries
These parameter variations allow our films to serve a wide range of applications:
- DTF and DTG Printing: Thinner films for soft garments, thicker films for bold graphics.
- Apparel Manufacturing: Used in the transfer of complex multi-color designs onto t-shirts, sportswear, and bags.
- Industrial Heat Transfer: Used for transferring labels and decals onto plastics and metals.
