Instead of collating products with an overwrapping machine, an alternative is to use a stretch wrapper. This system wraps using low cost polyethylene film and utilises two reels of film to produce a web through which the product is pushed. Unlike an overwrap, the ends of the wrap are left open.
Once the product has been collated it is positively transferred through the film web. The film is stretched tight around the product and is then heat sealed. The band produced is strong enough to hold the multipack together and enables a dramatic decrease in the use of packaging.
Marden Edwards stretch banders are available in film width versions of 300, 600 and 1000mm. The feeding orientation can either be in line or from either side. The construction is extremely rigid which makes the machine suitable for the harshest of environments.
