A semiautomatic shrink packaging machine which uses roll-fed thermoplastic film folded in half along its length. A product or group of products are placed between the two halves of film. The film is then sealed and cut off around the product with an L shaped sealing bar. The pack is then passed through a heated tunnel to shrink the film around the product to produce a tightly enclosed pack. Widely used for wrapping books, video tapes, floppy disks, foodstuffs such as dried fish, boxed products, etc.
A shrink packaging machine in which thermoplastic film is wrapped around a package or group of packages as it moves between two rolls of web that have had the ends welded together. After the package has completely passed between the web rolls, a set of I shaped sealing bars push the trailing webs together, apply heat to seal the webs together and cut it free. The pack is then passed through a heated tunnel to shrink the film around the product to produce tighly bundled pack. Widely used for packaging a group of boxes containing foodstuffs or sundry goods, or a group of PET bottles, cans or paper containers for beverage.
