Stretch Bander / Sleeve Sealing Machines

The BVM stretch Banders use an upper and lower film roll. In conjunction with a film stretching device a tight film sleeve is produced around the product.

The film is stretched by means of rubber wind-back rollers, the degree of stretching being infinitely adjustable. With this system it is possible to stretch wrap product stacks or multi-packs of e.g. bottles or cans without shrinking. Alternatively a following shrink tunnel can be used as well.

Function The products are fed via transport conveyor in line or at right angles. The multi-pack is either formed in the machine or it arrives already pre-grouped by the customer. The sleeve sealing machine or the stretch bander is using an upper and lower film roll which are welded as a so-called „film curtain". During the transport resp. infeed movement a film sleeve is sealed around the product. In the following shrink tunnel the products are shrunk to a stable multi-pack which can be safely transported. The shrinking result can be regulated within the heating zones by means of an electronic temperature regulation and adjustable air flaps.
