Introduction to PET Heat Transfer Film

PET heat transfer film is a heat transfer medium based on polyester film, widely used in garment printing, pattern transfer, packaging surface decoration, and industrial labeling. Compared with traditional transfer materials, PET heat transfer film offers significant advantages in dimensional stability, high-temperature resistance, and surface flatness, making it suitable for applications requiring high precision and consistent finished products.

PET polyester heat transfer film, also known as PET transfer film or PET release film, involves applying several coating release layers on a PET film substrate. Commonly available in thicknesses ranging from 75u to 120u, this film features both hot and cold peeling options and a matte surface. It undergoes anti-static and anti-scratch treatments to enhance adsorption and adhesion properties.

The operational heat transfer temperature ranges from 130-160 °C, achieving a complete transfer effect. The film's surface may feel slightly sticky when heated but becomes smooth upon cooling. Its back-coated anti-adhesive layer prevents damage from adhesion during long-distance transport, thus saving on transportation costs and is suitable for fine pattern to block color printing achieving ideal results with 175-210# screen printing screens.

This film has passed the BV test and meets Oeko-Tex Standard 100 certification, demonstrating its resistance to high temperatures, washing, and weather conditions. Made from polyurethane, it remains non-sticky at 60 degrees and does not harden or become brittle at temperatures as low as -30 degrees.

Analysis of Key Parameters of PET Heat Transfer Film

Choosing the correct specifications is crucial for ensuring stable transfer printing results. The following parameters directly affect your production efficiency and product quality:

Thickness:

• Common range: 50μm – 125μm

• Thinner (50–75μm): Good flexibility, suitable for curved or soft substrates

• Medium thickness (75–100μm): General purpose, suitable for most garment and label transfers

• Thicker (100μm+): Higher strength and stability, suitable for high-precision or industrial applications

Heat Resistance:

• Standard operating temperature: 130–180°C

• High-temperature resistant model: Supports higher heat pressing temperatures, suitable for special inks or applications requiring high adhesion.

Coating:

• General-purpose coating: Suitable for water-based, solvent-based, and UV inks

• High-adhesion coating: Used for difficult-to-adhere substrates such as leather and synthetic materials

• Peelable / Cold peel / Hot peel: Affects the processing method and the appearance of the finished product

Flexible Peel Options: Available in True Hot Peel (peel instantly for high efficiency) and Cold Peel (for ultra-matte, delicate textures).

Benefits of Using PET Heat Transfer Film Paper for Screen Printing

PET heat transfer film paper, also known as hot peel plastisol transfer paper film, offers several benefits:

• Excellent heat resistance: Can withstand high temperatures without warping, ideal for transferring plastisol inks.
• Enhanced print quality: Provides a smooth surface for detailed printing, ensuring uniform ink adhesion for sharp, vibrant prints.
• Easy release of transferred design: The hot peel feature allows for quick paper removal post-transfer, leaving a clean design.
• Versatile compatibility: Works with a variety of fabric types and colors, suitable for diverse screen printing projects.

Standard Operating Procedure

This operating procedure is based on various application scenarios including garment printing, label transfer, and industrial surface decoration, and conforms to the process standards of mainstream heat press equipment. Correctly following these steps will significantly improve transfer durability, image clarity, and production stability.

Step1: Surface Preparation

Before transfer printing, it is essential to ensure that the substrate surface is clean, dry, and smooth, as this is the primary factor affecting adhesion.

Key operating points:

• Remove dust, oil, moisture, silicone oil residue, or release agents from the substrate surface.

• For fabric materials (such as cotton, polyester, and blends): It is recommended to perform a 2–3 second pre-press to remove moisture and wrinkles.

• For leather, synthetic materials, or coated materials: Gently wipe the surface with a lint-free cloth and alcohol to ensure there is no oil film.

Quality control standards:

• No visible particles on the surface

• No obvious moisture or oil stains

• Smoothness meets the requirements for uniform heat press contact.

Step2: Printing & Drying

The pattern is printed onto the coated surface of the PET heat transfer film using a suitable ink system.

Ink Compatibility:

• Solvent-based inks

• UV inks

• Water-based inks (requires complete drying)

Operating Points:

• Ensure the printed pattern has uniform color and sharp edges.

• The ink must be completely dry before heat pressing; otherwise, it may cause: Bubbles, Pattern spreading, Poor adhesion after transfer.

Recommended Standards:

• Air drying at room temperature for ≥ 10–30 minutes (depending on ink type)

• Or use low-temperature drying equipment to accelerate drying.

Step3: Positioning

Place the printed PET heat transfer film onto the target position of the substrate, ensuring precise positioning.

Key operating points:

• The printed side should be in direct contact with the substrate, with the film facing outwards.

• Secure with high-temperature resistant tape or a positioning frame to prevent displacement during heat pressing.

• For multi-color or multi-layer patterns, pre-alignment is required to confirm the overall layout.

Quality control standards:

• The pattern edges should be aligned with the positioning lines on the substrate.

• No obvious wrinkles or curling of the edges.

Step4: Heat Press Transfer

This is a critical step in determining the final adhesion effect, requiring simultaneous control of three core parameters: temperature, pressure, and time.

1) Temperature Setting

• Typical range: 140–170°C

• For high-adhesion or industrial coating models, the temperature can be increased to 180°C (testing required for confirmation).

2) Pressure Setting

• Medium to high pressure is recommended.

• Ensure even pressure distribution across the entire pattern area to avoid incomplete transfer in certain areas.

3) Time Control

• Standard time: 8–15 seconds

• For thick patterns or multi-layer inks, the time can be extended to 15–20 seconds.

Operating Procedures:

• The heat press plate should completely cover the pattern area.

• Avoid repeatedly moving the heat press head to prevent ghosting or stretching deformation.

• Parameters should be fine-tuned based on the actual pressure distribution for different equipment (flatbed press, roller press, automated equipment).

Step5: Peeling

Based on the coating type of the PET heat transfer film, select the correct peeling method:

Peeling Type:

• Hot Peel: Peel immediately after heat pressing

• Cold Peel: Peel after the substrate has cooled to room temperature

Operating Points:

• Maintain a 180° peeling angle

• Peel evenly and steadily, avoiding rapid pulling that may cause the edges of the pattern to lift

Quality Standards:

• No adhesive residue after film peeling

• The pattern edges are clear and undamaged

Step6: Post-Press(Optional)

To improve washability, abrasion resistance, or industrial adhesion strength, a second heat pressing is recommended.

Instructions:

• Cover the design surface with a silicone release paper or non-stick film.

• Heat press again for 3–5 seconds.

• Maintain the same temperature as the first heat pressing.

Improved results:

• Enhanced adhesion

• Smoother surface

• Increased resistance to friction and washing cycles

Attention Points For PET Heat Transfer Film

During the printing production, avoid scratching or touching the film with sharp objects. Store the PET transfer film in a room that maintains constant temperature and humidity. The shelf life of the film is 1 year from production if the package remains unopened. Post-printing, it is advised to wait 24 hours before washing the fabric.
