REQUIREMENTS
- 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
| Product | Size | Format | —— | Closure |
|---|---|---|---|---|
| 1-kg sacks | 115x85xH130 | 5×2 | 2 | internal flap |
| 2-kg sacks | 115x85xH200 | 5×2 | 2 | internal flap |

| 5-kg sacks | 190x95xH250 | 5×1 | 3,5 | internal flap |
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.
