What Are Shrink Sleeve Labels?

Shrink sleeve labels are full-coverage labels made from heat-sensitive plastic or vinyl film, custom-designed to fit a product’s unique shape. Once printed, the film is formed into a tube and slipped over the product. Heat is then applied, shrinking the sleeve to perfectly conform to the contours of the container.

How Shrink Sleeve Labels Differ from Traditional Labels

Unlike pressure-sensitive labels that rely on adhesive to stick to the container, shrink sleeve labels use heat to adhere. Traditional labels, often made of paper, can degrade when exposed to moisture or friction. Shrink sleeves, however, are printed on the inside of durable plastic film, protecting them from wear and tear.

The absence of adhesives makes shrink sleeves easier to remove and better suited for products exposed to harsh conditions, such as cleaning agents, moisture, or fluctuating temperatures.

How Shrink Sleeves Are Manufactured

The process begins with custom printing on the film, either digitally or using flexographic presses. The material is then converted into tubular sleeves, leaving openings at the top and bottom. These tubes are designed to fit snugly over the product container, with expert adjustments made to ensure the graphics and text remain clear and undistorted after shrinking.

Once the sleeves are applied to the product, they are subjected to heat or steam, which causes them to shrink and conform to the container’s shape. Proper storage and handling during this stage are critical, as exposure to extreme temperatures can impact the quality of the labels.

Applications for Shrink Sleeve Labels

Shrink sleeve labels are versatile and can be used across a wide range of industries, including:

• Pharmaceuticals and Nutraceuticals: Tamper-evident seals and added durability protect product integrity and consumer trust.
• Household and Personal Care: Labels for detergents, cleaners, and hair care products withstand moisture, chemicals, and abrasion, ensuring longevity and readability.
• Food and Beverage: Full-body designs enhance branding while providing critical information in compliance with industry regulations.

Shrink sleeves can also be used for multipack bundling or as standalone tamper-evident bands, offering convenience and added security.
