Film packaging for pallets was developed by a German chemical producer in the mid-1960s, based on using shrink film. The film is produced as a tube using blow head extruders with tubular dies, which are then further processed or slit open to become a flat film. Hot air heats the film during the shrinking process up to the softening point. The film is shrunk to fit perfectly around the palletized goods, which, after cooling down, creates the necessary stability to secure the load. The heat required for the shrinking process is produced by the packaging system either electrically or with gas. If required, the pallet can be packaged leaving its base open for the skids of the fork-lift. This allows high-bay storage. It is also possible to draw the film over the pallet base. The shrinking method is particularly suited for products that are sensitive to elastic packaging stacking, such as glass. The goods are reliably protected against environmental impacts such as snow, rain, UV radiation, dust and insects. However, the shrinking process causes the film to become milky, which makes it difficult to see the packaged goods or imprinted bar codes. Additional disadvantages: polyethylene (PE) bags might weld to the packaging film and the heat effect can be a fire hazard, in this regard the new solution is Stretch Hood packaging. Due to deletion of the heating stage, this method is much safer and cost effective.
