Shrink sleeve labels are full-color, 360-degree printed labels that utilize heat in the application process to conform the label to the shape of the container. The labels are typically printed on either plastic or polyester film material and are commonly used on aluminum cans and glass or plastic bottles..
One of the greatest advantages of using shrink sleeves is that it allows you a 150 percent increase in label real estate compared to pressure sensitive labels. This additional space can be used to help tell your brand story, add more imagery, or make room for all of the regulatory information that needs to go on your label.
Beyond branding, shrink sleeves can function as more than just a label. Like in the Tylenol example, shrink sleeves can double as tamper-evident sealing to give your products the extra security they need with a perforated shrink cap. Shrink sleeves can also be used to package multiple items together for the purpose of offering it as one product. Because shrink sleeves are form-fitting, you can package different sized and shaped containers, like free samples or two-for-one deals, together easily.
Once your sleeves are ready, it’s time to apply them to your containers. In addition to printers – and sometimes converters – you may also require an applicator if you don’t have the right equipment in house. Either way, the sleeves are slipped over your containers and sent through a heat or steam tunnel, where the intense heat will shrink the film around the container.
