A heat-sensitive plastic film, typically made from PVC, PET, or similar materials, which is applied to a product and then shrunk tightly around it using heat. The shrink sleeve conforms to the shape of the item, creating a full-coverage, 360-degree design that can be used for branding, labeling, and protection. Commonly used for products like bottles, cans, and containers, providing a tamper-evident seal and enhancing product appearance with vibrant graphics and branding. They are popular for their ability to cover complex shapes and provide a high-quality, professional look.
