How to Store and Handle PET Film for DTF Printing
Direct-to-film (DTF) printing involves transferring digital designs onto special PET film, which is then placed onto garments using heat and pressure. Proper storage and handling of PET film are crucial to ensure successful DTF printing outcomes. This article will provide comprehensive guidelines on how to store and handle PET film for optimal results.
Storage Environment
Temperature: Store PET film in a controlled environment between 68째F and 77째F (20째C and 25째C). Extreme temperatures can cause the film to shrink or warp.
Humidity: Maintain a relative humidity between 30% and 50%. Excessive moisture can damage the film’s coating, while overly dry conditions can make it brittle.
Light Exposure: Protect PET film from prolonged exposure to direct sunlight or fluorescent lighting. UV radiation can degrade the film’s surface finish.
Handling Techniques
Wear Gloves: Always wear gloves when handling PET film to prevent moisture and oils from transferring to its surface.
Avoid Sharp Objects: Handle the film carefully to avoid scratching or tearing it with sharp objects. Use clean tweezers or forceps to adjust it as needed.
Inspect the Film: Before printing, inspect the PET film thoroughly for any defects, scratches, or wrinkles. If any imperfections are present, replace the film promptly.
Storage Duration and Precautions
Shelf Life: Store PET film in its original packaging to maintain its integrity. The shelf life of PET film is typically around 6 months, but it can vary depending on the manufacturer and storage conditions.
Packaging: Keep PET film rolls in their protective packaging to prevent moisture, dust, or other contaminants from accumulating on its surface.
Roll Storage: Store PET film rolls vertically to prevent bending or distortion of the film.
Additional Considerations
Moisture Prevention: Use moisture-absorbing materials, such as silica gel packets, inside the storage area to keep the environment dry.
Regular Inspections: Periodically inspect stored PET film for signs of damage, discoloration, or other issues.
Training: Ensure that all individuals handling PET film are properly trained on storage and handling procedures to minimize risks of damage.
Conclusion
By following these guidelines for storing and handling PET film, DTF printing users can ensure the longevity and quality of their prints. Proper storage and handling will prevent premature degradation, ensure accurate color reproduction, and facilitate consistent print results, contributing to the success of their DTF printing operations.
