Understanding Different PET Film Grades and Their Uses in DTF Printing

Direct-to-film (DTF) printing is a versatile technology that allows for the transfer of intricate designs onto a wide variety of fabrics. PET film grades are crucial components in DTF printing, as they determine the quality and durability of the printed transfers. In this article, we will delve into the different types of PET film grades available and explore their specific uses in DTF printing.

Types of PET Film Grades

Cold Peel PET Film

Cold peel PET film is the most commonly used grade in DTF printing. It offers a cost-effective solution and produces excellent transfer results. After printing, the film can be peeled away from the transfer paper when cold, allowing for efficient and straightforward processing.

Hot Peel PET Film

Hot peel PET film requires the use of a heat press to remove the film from the transfer paper. This film offers increased durability compared to cold peel film, making it suitable for applications where durability is critical. However, it requires more precise temperature control during the transfer process.

Universal PET Film

Universal PET film is a versatile grade that can be used for both cold and hot peel transfers. It offers a balance between cost-effectiveness and durability, making it a popular choice for a wide range of applications.

Factors to Consider When Choosing a PET Film Grade

Thickness

PET film thickness influences the rigidity and durability of the transfer. Thicker films provide more protection and are less prone to tearing, while thinner films are more flexible and easier to fold around complex designs.

Surface Treatment

The surface treatment of PET film affects its adhesion properties. Films with a high surface tension will adhere well to transfer paper, while those with a low surface tension will require additional treatments. Proper surface treatment ensures optimal transfer quality.

Optical Clarity

Optical clarity refers to how well the film allows light to pass through it. Clear PET films are essential for vibrant and accurate color reproduction, while opaque films can be used for specific applications where opacity is desired.

Applications of Different PET Film Grades in DTF Printing

Cold Peel PET Film:

Applications include T-shirt printing, tote bags, and other casual wear.

Hot Peel PET Film:

Applications include workwear, sports uniforms, and garments subjected to frequent washing and wear.

Universal PET Film:

Applications include a wide range of fabrics, including cotton, polyester, and blends.

By understanding the different PET film grades available and their specific properties, DTF printers can optimize their printing processes and achieve the desired results. Careful consideration of the factors discussed in this article will lead to improved transfer quality, durability, and cost-effectiveness in DTF printing.
