The heat shrink sleeve is a label printed on plastic film —PET-G or PVC, typically 45 to 50 microns— that is applied loosely around the container and shrinks with heat until it hugs its complete geometry: necks, shoulders, and curves included. Unlike a flat pressure-sensitive label, it decorates 100% of the container perimeter in 360° and can include transparent windows to see the product.
In Mexico, Etival Etiquetas (plant in the Valley of Mexico) manufactures heat shrink sleeves printed in flexography with up to 8 inks, with a free 3D render of the container before production, runs from 10,000 sleeves, and delivery in 15 business days on new projects.
How it works, step by step
- 01Flexographic printing on or film in reel form, with up to 8 inks plus opaque white and inline finishes: , , embossing, and .
- 02Sleeve formation: the film is delivered in a format ready for the applicator (or folded and sealed into a tube, depending on the line).
- 03Application onto the container: the sleeve slides on loose — manually, semi-automatically, or automatically within the packaging line.
- 04Shrinking: the container passes through a heat tunnel at 130–160 °C and the biaxially oriented film contracts in a controlled way until it fits the contour.
- 05Cooling and register verification: the sleeve ends up fixed with no adhesive, with the artwork in register.
When the heat shrink sleeve makes sense
- Containers with complex geometries — conical necks, curved shoulders, embossed bottles — where a flat label can't reach.
- Brands seeking 360° decoration with maximum communication surface: isotonic drinks, waters, dairy, beer, personal care.
- Products that live in the cold chain or on ice: the film does not peel off with the condensation that degrades paper.
- Special editions and seasonal campaigns: the sleeve “dresses” the entire container without changing the mold or the base container.
- Designs with a product window: unprinted areas or translucent ink let the content show through.
And when it doesn't: if your container is a simple flat surface, your artwork fits on a front panel, and your line has no shrink tunnel, the pressure-sensitive label is more economical and simpler to apply. The sleeve shines when the container or the brand calls for more perimeter.

Technical comparison of the two most common labeling routes in beverages and foods
PET-G, PVC, and OPS: which film to choose
- PET-G: the beverage-industry standard — high shrinkage, gloss, and register stability.
- Floatable PET-G: separates by density in PET recycling plants — designed for circular-economy streams.
- PVC: the economical option for low-cost applications where there is no recycling requirement.
- OPS: an alternative with good shrinkage for specific containers; evaluated case by case.
Technical checks before deciding
Three checks prevent 90% of sleeve problems: that your line has a shrink tunnel (or the space to install one), that the film's shrink percentage is coordinated with the container geometry from the brief onward, and that the opening microperforations sit where the consumer actually tears. All three are defined in the technical analysis stage — before printing.
