HappyFlex SubliBlock Heat Transfer Vinyl

HappyFlex SubliBlock Heat Transfer Vinyl was especially developed for resublimating polyester textiles. Of course it can be used just as well on cotton, regular polyester or poly/cotton blends.

About sublimation:

Special sublimation dyes are used to colour polyester fibres. Many shirts used in the sporting industry can resublimate: the colour bleeds through and discolours the transfer vinyls. This does not happen with 100% cotton. It is also important to note that not all polyester fabrics are sublimation dyed. Thus resublimation does not happen with every polyester textile.


  • suited for sublimated polyester, cotton, regular polyester and poly/cotton blends
  • available in eleven brilliant colours
  • perfect opacity
  • matt surface

HappyFlex vinyls can be cut with cutters, stencils or by hand.

Remember to:

  • mirror design before cutting,
  • always make a test cut when using a cutter.
