Inks That Shrink

With the use of shrink-sleeve labeling for product decoration growing at a double-digit rate, suppliers of shrink film inks are developing a steady stream of products to carve out a piece of the action. But in addition to the normal adhesion issues that are common with non-porous film applications, shrink inks have several other factors to contend with that make their development more challenging. Some of these issues include distortion (cracking, delamination, etc.), blocking, coefficient of friction (COF), and in food and beverage applications, low odor.
