Möllers automatic transverse stretch hooders use the security potential of the stretch film in the most effective way: The tubular film hood is radially stretched to the drawn width, with the resultant retractive force the film is tightened around the pallet load during positioning. Through the development of the patented High-Expander and Ultrastretch technologies Möllers was able to significantly improve the transverse stretch hood process. With the highly extensible films used here considerably higher tensile strengths have been achieved, which significantly improve the load integrity and the bond between load and pallet compared to the stretch films originally used. Further advantages of the modern stretch process are the suitability of a single tubular film width for all usual pallet formats and the reduced film consumption of up to 30 %.
Shrink wrapping packaging plants
Möllers has developed film-shrinking technology with many advances since its beginnings and has gained the reputation of a technology leader in this field. Pallet security with shrink-wrap film has proven its area of application for very heavy shipping units and multiple pallet handling. Tubular film drawing machines FSA serve pallet-securing with shrink-film hoods which are used for very heavy shipping units and extremely harsh transport environments, produce the hoods from tubular shrink-film and draw them over the stack of packaged goods reaching to under the pallet. For tight shrinking the film is heated by a downstream shrink frame.
Film shrink-frames round off the tubular film drawing machines with which they are linked via a transport line to accept the covered pallets and to shrink tight the film with its vertically moveable, gas-heated (SR-G) or electrically-heated (SR-E) heating-frame. Möllers shrink frames satisfy highest safety requirements and can be equipped with monitoring units, e.g. temperature checking systems.
As one of the pioneering developments in this field Möllers brought out the space-saving tubular film drawing machine with integrated shrink frame, which shrinks the film hood tight immediately after the film is drawn over. Tubular film drawing machines Combi-FSA are built with electric and gas heaters. Non-contact drawing, guided undershrinking and contra-laminar-system are also options for these machines, which are available either in a 2 or 3 bobbin version with automatic film change.
