  • Handling very heavy products
  • Avoiding the top of the sack from being damaged

The difficulties posed by this specific product were:

  • the considerable weight
  • the lack of compactness of each individual pack
  • there was a considerable difference in texture as the format changed
  • the top of the sack had to be folded accurately before being wrapped by the cardboard

Raffaello Multifila proved to be the winning solution; it was equipped with a dedicated system for folding the upper flap of the sacks and the adjustable pushing system solved the problem posed by the varying textures.
