What are PET shrink sleeves?

Introduction

PET shrink sleeves are a type of plastic labeling material made from Polyethylene Terephthalate (PET) — a durable, recyclable, and high-clarity polymer. These sleeves are commonly used in product packaging to create 360° full-body labels that tightly conform to the shape of containers such as bottles, cans, and jars once heat is applied.

PET shrink sleeves provide excellent design flexibility, vibrant print quality, and strong resistance to moisture and abrasion, making them one of the most popular choices for modern product labeling across food, beverage, and cosmetic industries.

How PET Shrink Sleeves Work

PET shrink sleeves are printed on flat film rolls, then formed into tubular labels. During the packaging process, these sleeves are slipped over the container and passed through a heat tunnel or steam tunnel. The PET material reacts to heat by shrinking up to 75%, tightly wrapping around the product surface — even if it has complex curves or contours.

This process allows brands to achieve seamless full-body decoration and protection without adhesive labels.

PET Shrink Sleeves vs. PVC Shrink Sleeves

While PVC shrink sleeves are cost-effective and widely used, PET shrink sleeves are more environmentally friendly and offer superior clarity and strength. PET also performs better at higher shrink ratios and is preferred in markets emphasizing recyclability and sustainability.
