Shrink sleeve labels are made from a polymer film that shrinks when heat is applied, conforming tightly to the shape of the container. This type of label offers 360-degree coverage, allowing for vibrant, full-color designs that can wrap around the entire product, making it ideal for complex shapes and sizes. Similarly, stretch sleeve labels are made from a flexible plastic material that stretches to fit over the container without the need for adhesives or heat. These labels are cost-effective and can be easily applied to a variety of container shapes. They are often used for products that require frequent label changes or for containers that are reused.
