Dow Shrink Label Adhesives

Shrink Sleeve Labels

Packaging and labels have become increasingly important for shelf appeal, brand recognition, and consumer loyalty.  This is likely why the shrink sleeve label market is expanding at such a rapid pace.  Shrink sleeve labels allow for 360° coverage of a package and provide a significant increase in the amout of space for branding, imagery, and information.  

Shrink Sleeve Label Processing

Typically, shrink sleeve labels are made of polyester, polyethylene, or PVC plastic films. These films have been pre-printed with designs and information that are sized to wrap and display appropriately around a specific container. When applying the printed label to the container, heat is used to shrink and seal the plastic label around the bottle, can, or other types of package. Due to the heat-sensitive nature of some of the plastic films used in shrink labels, excessively high heat must be avoided during shrink label manufacturing.

Shrink Sleeve Label Adhesion

An adhesive is often applied beforehand to the shrink sleeve film, allowing it to stay firmly in place and not rotate around the container during handling. This adhesive is a heat-sealable coating, or heat seal coating, which is a thermoplastic coating that may be used to seal a flexible substrate to a rigid substrate. In the case of shrink sleeves, the heat seal coating adheres the shrink sleeve film to the container.

When applied to shrink sleeve films, heat seal coatings are not tacky until they are heat activated above a specific temperature, known as the "activation temperature.” Once activated, the heat seal coating can form bonds and adhere substrates together. This property is leveraged effectively with shrink sleeve labels since heat is required to shrink the film to fit the intended container.

Due to the heat sensitivity of the films mentioned in the previous section, the heat seal coating cannot have an activation temperature higher than what the shrink sleeve film can tolerate. Therefore, a heat seal coating that is specifically designed for shrink sleeves must be used.

Brand owners in many industries, such as food and beverage, personal care, and household cleaning supplies, benefit from the use of shrink sleeve labels to market their goods. Bottles, cans, spray canisters, and other containers are packaging examples that allow for full wrap-around coverage to present information and unique branding. Shrink sleeve labels often require adhesives to adhere the label better onto the container, and the right adhesive must be used to avoid damage to the label material. Dow's heat seal coatings are engineered to activate and bond at the right temperature and to a wide variety of plastic films used in shrink sleeves.
