they give unmatched clarity, gloss and presence on the product. The surface printing can be done with existing technology and without pretreatment of any kind. Copolyester resins for shrink film also offer high shrink force for added versatility.
EMBRACING SUSTAINABILITY The advantages for the copolyester resins for shrink film go beyond their aesthetics. They have sustainability advantages that have undeniable benefits to the bottom line. Amongst the benefits are: exceptionally high film strength and good tolerance to down-gauging – key attributes that allow users to reduce material consumption by as much as 10 percent compared to other copolyesters. These unique properties enable fabricators to make more labels from the same amount of material. And given the inherent strength properties found in the resins, their popularity will only grow in tandem with the trend to get more with less. The resins for shrink film allows for full container body labelling (the container’s widest point) and also a tamper indicating device at the neck of the container (the narrowest point). Other materials require the use of an additional neck band as well as a second pass through a shrink tunnel, increasing attendant production line time and creating potential quality issues.
Like all shrink film labels, copolyester resins can be fully removed
from containers with no glue residue, allowing for cleaner input to reclamation streams and easing the burden on recyclers. Plus, they deliver material savings because there is no machine
direction shrinkage. In fact, it actually grows, which allows brand owners and converters to use smaller labels that still cover the entire bottle.
“As plastic and glass bottle shapes become more romantically contoured to connect emotionally with consumers, so too must the labels that fit them”
AN OBVIOUS CHOICE? Shelf appeal is a key consideration for brand owners in the field of differentiation. Not only do the copolyester resins for shrink film save on secondary packaging costs, they can be used on a variety of sized and contoured package designs, clearly differentiating products from their neighbours. These advantages, coupled with new sustainability benefits, make the line of resins for shrink film the clear choice for shrink labels – a market leader today and an innovator for tomorrow.
