Why Do Some People Use the Same Heat Transfer Film for Half a Year While Others Use It for Three Years?
The 3D flock heat transfer films that have become popular in the last two years use a foaming process to enhance their three-dimensional effect.
The difference in the lifespan of heat transfer films mainly stems from three underlying factors:
Transfer Efficiency: Heat transfer films with a PET substrate typically achieve a transfer efficiency of over 90%, while low-quality films leave noticeable adhesive residue.
Weather Resistance: Reflective lettering films used for outdoor apparel require UV resistance of at least five years, whereas ordinary decorative films may fade within just one year.
Peel Method: Cold-peel films are temperature-sensitive, while hot-peel films require precise temperature control; choosing the wrong method can cause the design to delaminate.
The 3D flock heat transfer films that have become popular in the last two years use a foaming process to enhance their three-dimensional effect, but the increased thickness reduces their stretchability, making them more suitable for flat substrates such as luggage and bags.
