How to Print on Shrink Sleeve Film: Complete Guide for Flexographic Printing
Introduction
Shrink sleeve labels are widely used in beverage, food, cosmetic, and pharmaceutical packaging due to their 360-degree branding capability and excellent visual impact. However, printing on shrink sleeve film is more complex than standard label printing because the material is highly sensitive to heat, tension, and ink adhesion.
In this guide, we will explain how to print on shrink sleeve film using flexographic printing technology, including material selection, printing process, common problems, and practical tips for better print quality.
What Is Shrink Sleeve Film?
Shrink sleeve film is a heat-sensitive plastic film that shrinks tightly around a container when heat is applied. It is commonly made from:
- PET-G (Polyethylene Terephthalate Glycol)
- PVC (Polyvinyl Chloride)
- OPS (Oriented Polystyrene)
Among these materials, PET-G is the most widely used due to its environmental friendliness and recyclability.
Shrink sleeve labels are printed flat and then formed into sleeves, which are later applied to bottles or containers using heat tunnels.
