More on Shrink Wrappers & Heat Tunnels - Single Item

Used in a variety of industries, including food and beverage, pharmaceuticals and even textiles shrink wrapping machines and related heat tunnel equipment offer efficient and durable packaging solutions. Shrink wrapping, or shrink bundling as it's sometimes called, is the process of using a film to cover or encase a single or group of items. The film is then moved on a conveyor through a heat tunnel, which shrinks it around the object, holding it in place. This provides a transparent and adhesive layer that enhances the product's aesthetics while providing added protection against dust, moisture, and other external elements. There are different types of films used with this equipment, including PVC and polyolefin, both of which have varying degrees of thickness and shrink rates, providing a large range of use cases for various product types of all shapes and sizes. The critical component of this system is the heat tunnel, which is often attached to the machine and completes the process by shrinking the film tightly over the objects. Heat tunnels contain both top and bottom airflow, which increases the level of control and ensures that the product is evenly heated. Depending on the size and capacity of the given machine, it can process upwards of 40 to 60 products a minute, significantly boosting production rates. As previously mentioned, its uses span across industries. In food packaging, shrink wrapping is commonly used to wrap individual and grouped food products, including fresh produce, meats and baked goods, providing a secure barrier and increasing shelf life. Its tamper-evident qualities also mean that any attempts to open or tamper with the product will be evident by a broken or damaged seal. This is crucial for pharmaceutical and cosmetic products, where the integrity of the packaging is essential in ensuring both product performance and consumer safety. They have also proven to be excellent packaging solutions for textiles like clothing and fabrics. Shrink wrapping clothes can help to maintain their quality and appearance, while also protecting them from dust, pests, and other environmental factors. Though often used together for the purposes of packaging, heat tunnels themselves are also used in textile production to shrink and bond materials together, creating seamless, wrinkle-free fabrics. This has revolutionized the textile industry, making it easier to create high-quality and durable products. This dynamic duo of machines has an abundance of value to add to any packaging process where an extra layer of security, or the bundling of multiple products together is needed.
