Labeling Equipment for Shrink Sleeve and Adhesive Label Application

Wienson specializes in shrink sleeve label applicators, shrink tunnels, and labeling machines for bottles, cans, cups and other containers used across different industries. Our product portfolio includes horizontal, vertical and twin-head shrink sleeve labelers, with models available for different product sizes, orientations and production speeds. After the sleeve is applied, electric or steam shrink tunnels use controlled heat to shrink the film evenly around the container and complete the sleeve shrink labeling process. We also offer self-adhesive labeling machines for single-side, double-side, flat-surface and horizontal labeling, along with print-and-apply systems for products that need variable information printed and applied during production.

Tamper-Evident Shrink Sleeves: Process, Benefits and Selection

Shrink sleeve labeling combines precise sleeve placement with controlled heat shrinking. The sleeve applicator, film, container and shrink tunnel should be evaluated as one process rather than as separate pieces of equipment.

What Are Tamper-Evident Shrink Sleeves?

Tamper-evident shrink sleeves are heat-shrinkable film labels used around a cap, neck or larger container area. Once shrunk, the film conforms to the package. A broken band, changed pattern, exposed message or other visible feature can indicate that the package has been opened or disturbed.

How Does Shrink Sleeve Labeling Work?

Sleeve Feeding and Cutting: Printed tubular film is unwound, guided over a forming mandrel and cut to the required length.
Sleeve Placement: The applicator positions the cut sleeve over the full body, a partial section or the cap area of the moving container.
Controlled Shrinking: The sleeved product passes through an electric or steam tunnel. Controlled heat contracts the film so it follows the container surface.

What Advantages Do Shrink Sleeves Provide?

Visible Package Security: Tamper bands and cap seals make interference easier to identify.
Contour Coverage: Shrinkable film can follow curved, tapered and irregular surfaces.
Flexible Label Coverage: One system can be configured for full-body sleeves, partial sleeves or neck bands.
Brand Presentation: Printed sleeves provide a large decoration area and consistent visual coverage.
Bundling Options: Shrink sleeves can also secure grouped products or promotional multipacks.

Common Shrink Sleeve Materials

PVC is widely used where cost and general shrink performance are priorities. PET and PETG offer clarity, durability and strong shrink characteristics. POF and OPS are used for selected package and process requirements, while PLA may be considered where a bio-based film is required. Material suitability should be confirmed against the container, printing process, shrink curve and tunnel conditions.

How to Select the Applicator, Film and Shrink Tunnel

Equipment selection should begin with the complete application. Review the container shape and material, sleeve location, film type and thickness, required security feature, production speed, available utilities and expected changeover frequency. The applicator must place the sleeve accurately, while the tunnel must deliver enough controlled heat to achieve an even finish without damaging the container or printed film.
