Features:

The latest version of our successful range of bottomers for hot-air sealed PP woven fabric sacks provides increased output, improved sack quality, extended flexibility and greater ease of operation. 

Sacks made out of woven PP are known for their unequalled robustness which combines with minimum material usage. The CONVERTEX produces woven PP sacks, which, in addition to these advantages, allow for automatic placement and filling and, as a result of their brick-type shape, provide obvious advantages in terms of logistic handling and an attractive presentation of the packaged goods.
