How a Sleeve Labeler Applies and Shrinks a Bottle Label
A sleeve labeler feeds tubular film, cuts it to length and places the sleeve around a container. A downstream shrink system then applies controlled heat so the film conforms to the bottle. Sleeve placement and shrinking are separate operations and can produce different defects.

Locate the defect before adjusting heat
Inspect the sleeve before it enters the tunnel. Incorrect height, twist or a poor cut points to film feed, cutting or bottle presentation. A correctly placed sleeve that wrinkles during heating directs attention to the film, bottle geometry and tunnel conditions.
Approve the package combination
Trial the actual film artwork and bottle, including the shoulder and base. Check print distortion, seam position and label stability after cooling. Changing film material or thickness may require a new shrink recipe.
