A sleeve shrink tunnel is a type of packaging machine commonly used in the food and beverage, pharmaceutical, and cosmetic industries. It is designed to apply heat to shrinkable sleeves or labels that are placed on a product or packaging. The shrink tunnel uses hot air or steam to create a uniform and tight fit around the product, giving it a professional and polished appearance. This process not only enhances the aesthetic appeal of the product, but also provides added protection and tamper evidence. Sleeve shrink tunnels come in various sizes and configurations to accommodate different packaging needs, making them a versatile and cost-effective solution for businesses looking to improve their packaging process.
