Rules for Overlaying Heat Transfer Films

The array of colors in the SEF flex and flock film product line opens the door to endless design possibilities. While many different films can be heat pressed on top of one another, you should follow the few simple rules listed below for trouble-free applications.

·      You can overlay any polyurethane flex film with any other flex film in the SEF heat transfer film product line.


In the design pictured, FlexCut Sweet Black was heat pressed first for five seconds; then FlexCut Sweet Yellow  was applied over the black for five seconds. Finally, Flexcut Sweet Red was pressed for 15 seconds.  The total time for heat pressing amounted to 25 seconds. 


·         While you can heat press a flock film over any polyurethane flex film, never apply any other heat transfer film over any flock film, nor should you apply any flex or flock film over a puff film.


In the applique above, VelCut Neon Pink is heat pressed over the initial layer of FlexCut Sticky White.

·         When overlaying multiple layers of film, heat press each layer for five seconds except the last layer which you should press for 15 seconds. Avoid exposing heat transfer films to protracted periods of heat, which can compromise the adhesion of the applique to the garment.  

·           Limit the total number of layers of heat transfer films to four films.


Four different films were used to create the graphic pictured. FlexCut Sticky Black was heat pressed for five seconds. Next, FlexCut Sticky Green and FlexCut Sticky Yellow were each pressed for five seconds each. The fourth layer of FlexCut Puff White was pressed for 15 seconds.  The total time for heat pressing was 30 seconds.

  1. Whether you have home movies on VHS, 8mm, Super8, or 16mm film, transferring them to DVD offers a number of benefits. Compared to these dated formats, DVDs are much more reliable and durable, as they don’t deteriorate and decompose over time like film. Preserving your family’s memories is definitely the greatest benefit. 8mm Film transfer to DVD
