Automatic Side Sealing Machine

HUALIAN BRAND BSF-5545LD High-Speed Side Sealing Machine is available with centerfold film to seal three sides, it adopts automatically or manually feed type, it suitable for fully automatic shrink wrapping.

Automatic side sealers operate using centre-folded shrink film opened up with the product sat inside, surrounded by three open sides. The machine sealing bar seals the sides which then creates a ‘tube’ of film around the product. As the products then progress through the machine, the back of the pack is ‘cross-sealed’ through the action of the sealing bar coming down to separate one product from the next. Side sealers deliver a totally enclosed pack and usually give a tighter bag than ‘L’ sealers. They also operate at faster speeds than most other shrink wrapping models. A key feature of side sealers is their ability to wrap products of unlimited lengths, unrestricted to the frame size of the sealer.

They have been designed to pack a wide variety of unlimited length products, using plastic shrink film including polyolefin and polythene, with impressive speeds and absolute reliability. These machines are designed to achieve high production output, even with frequent format changes and over a wide range of product sizes.
