a linear shrink wrapping machine is a type of packaging equipment designed to wrap products in shrink film and then apply heat to shrink the film tightly around the product. This type of machine is often used in high-speed production lines and is ideal for packaging a wide range of products including food, beverages, pharmaceuticals, and consumer goods.
How Linear Shrink Wrapping Machines Work
Product Feeding:
Products are fed into the machine in a linear fashion, typically via a conveyor belt. The linear design allows for continuous and efficient operation.
Film Application:
Shrink film, usually made from materials like PVC, polyolefin, or polyethylene, is unwound from a roll and applied around the product. The film can be in the form of a flat sheet or a tube.
Sealing:
The machine seals the film around the product. This is usually done using heat sealers which create a seam by melting and bonding the film together. The sealing process encloses the product in a loose-fitting wrap.
Heat Shrinking:
The sealed product passes through a heat tunnel where hot air is circulated around it. The heat causes the shrink film to contract and conform tightly to the contours of the product.
Cooling:
After shrinking, the wrapped product is cooled to set the film and ensure a tight, secure wrap.
Unloading:
The wrapped product exits the machine, ready for further packaging, storage, or shipping.
