When formulating a water-based acrylic pressure-sensitive adhesive for labels, Tg is usually one of the first parameters we set. It indicates whether the dry adhesive film will behave relatively soft or firm at a given temperature and influences initial tack, peel adhesion, holding power, low-temperature performance and adhesive ooze. However, Tg alone does not determine whether an adhesive is sui...

When UV ink comes off during a tape test, the primer is often blamed first. However, poor adhesion can also result from the film surface, contamination, incomplete primer drying or incorrect UV curing. Here, “adhesion promoter” refers to a primer applied before printing. No single grade is suitable for every plastic film. Choose the Primer by Substrate PET and BOPET films often benefit from a prim...
