After printing properly, the custom shrink sleeve labels can be applied by hand or with the automatic equipment to heat shrink them on to your container. Then, the container with shrink sleeve is sent through a heat tunnel, where heat activated adhesive causes the label to shrink and conform to the contours of the container. From this point, all that remains is to fill your container with product and let the aesthetically pleasing look of custom printed shrink sleeve labels sell your product!
