Packaging
Polypropylene bags
Bags manufactured from circular woven polypropylene fabric are durable and versatile packaging for a wide range of bulk goods. The special weave structure of the fabric ensures the bag is breathable, which is crucial for storing sensitive and ‘breathable’ products.
The use of a polyethylene insert makes the sack dust-tight and protects substances from getting wet. The sack's construction from coated PP fabric ensures dust-tightness.
It is possible to make side overlaps in the bag, which improves the stackability of filled bags on pallets.

The traditional colour of the bags is white, yellow, and blue. Other colours can be agreed on a bespoke basis, with a production minimum.
Standard bag widths are 50, 55, 60, 63, 65 cm. Maximum height of the sack - 125 cm.
Other sack widths (40, 45, 70, 80 cm) can be produced to individual order with a production minimum. It is possible to produce bags with larger dimensions (above 80 × 125 cm), however, these will be bags with side seams.
It is possible to print on the bags (maximum 3 colours) according to the customer's requirements and design.
