Packaging panels of expanded polystyrene
Product packaging panels of expanded polystyrene used to be a problem: right after wrapping the film around the item the heat within the shrink tunnel would result in the surface of the panels to wrinkle. Macintosh Due realized that product packaging with two-reel devices required much more heat for shrink wrapping as compared to product packaging with devices having a tie-shaped wrapping system. Mac Due took around the challenge and was the first company to create a machine with tie up-shaped wrapping system big enough to package panels.
An additional fascinating solution is the use of ?°Leister?± models instead of shrink tunnel. In circumstances in which ?°extreme?± shrinking was not needed, diminishing the film around the edges of the package with the use of these powerful commercial blow dryers was regarded as adequate. Throughout the diminishing process the heated atmosphere contained in the package would create air wallets, stopping the film from getting into contact with the polystyrene until the film was cooled.
Competing producers constructed tie up-shaped wrapping techniques for sections, nevertheless the ?°ties?± had been so big they encountered problems with the slipping of the film. These companies used rollers to aid the placement of the sections into the ?°tie?± but this led to the disbanding from the piles of products with a few lightweight sections. MacDue met the problem by substituting the rollers with a mechanical pusher installed below. The solution guaranteed insertion in to the tie up-shaped wrapping system without disbanding the bundle, and permitted the machine to deal with shorter products.
In 2005, Macintosh Expected patented a brand new Centre-foldable device, to set up in devices with tie up-formed wrapping techniques. It was in response to issues in operating a very weighty center-folded away film reel in such big machines. Mac Expected developed an innovative remedy that empowered the use of two reels of simple film, leading to facilitated reel dealing with, increasing from the machine?ˉs autonomy, and easier printing on film.
