Heat transfer film and IML (In-Mold Labeling) are widely used in various industries for labeling and decorating products. These films are sensitive to environmental factors such as temperature, humidity, and UV rays. Proper storage of heat transfer film and IML is essential to maintain their quality and ensure their durability. Here are some tips on how to store heat transfer film and IML:

1. Store in a dry place: Moisture is the biggest enemy of heat transfer film and IML. It can cause them to wrinkle, fade, or lose their adhesive properties. Therefore, it is essential to store them in a dry environment. Use a humidity meter to monitor the humidity levels and ensure it is between 30-50%.

2. Keep away from sunlight: Direct exposure to sunlight can cause heat transfer film and IML to discolor or fade. Therefore, it is important to store them in a dark place, away from windows or other sources of sunlight.

3. Avoid extreme temperatures: Heat transfer film and IML can suffer from thermal contraction and expansion if exposed to extreme temperatures. They can curl, peel off, or crack. Therefore, it is recommended to store them at room temperature, between 20-25°C.

4. Protect from dust and dirt: Heat transfer film and IML can attract dust and dirt, which can affect their adhesion and appearance. To avoid this, store them in sealed bags or containers to protect them from dust and dirt.

5. Keep them flat: Heat transfer film and IML can get wrinkled or folded if stored incorrectly. To keep them flat, avoid stacking them on top of each other and store them in a horizontal position.

In conclusion, proper storage of heat transfer film and IML is crucial to ensure their quality and longevity. Follow these simple tips to keep them in good condition and maximize their use.
