Packaging Technology: Stretch, Sleeve, or In-Mold; Labels Do More
Yes, pressure sensitive labels are still used on much of the gallon jugs sold in the U.S., but particularly when it comes to single-serve products, processors have more label solutions to choose from than ever.
Roll-fed stretch sleeves work well with straight sided single-serve bottles and are often used with PolyEthylene Terephthalate (PET) bottles in pints or other sizes. Roll fed labels are relatively easy to apply, and no heat tunnel is needed. These types of labels allow 360 degree graphics, which is why they have sometimes also been applied to gallons and half-gallons.
Shrink sleeve labels are the best solution for contoured bottles and typical applications are for blowmolded high-density polyethylene (HDPE) bottles. A shrink sleeve can cover the full body of a bottle and therefore can be designed to provide tamper-evident neck and cap seals while offering maximum graphic space. Shrink sleeves are typically applied to bottles after filling and then shrunk to fit with a heat tunnel.
In-mold labeling presents lots of opportunities for dairy, particularly in the areas of yogurt and ice cream. Packaging that can be manufactured in-house can benefit from the “no-label look” and functionality of in-mold labels.
