The strength of the sack is its most important characteristic. It is what makes the sack stand out compared to other industrial sacks. The reason is the fabric, woven of polypropylene stretched tapes, which makes the sack resistant to dropping, pressing and bending. Even when handled with a hook or damaged on a nail the sack does not rip open and spill holds its contents. The special sack protects your goods from factory to end consumer The most important characteristic of packing units is the guarantee that the filling material will be kept as safe as possible from the factory to the end consumer. Strong cloth keeps the number of sacks broken or damaged during use to a minimum. Varying sack properties according to the specific filling goods - from airtight to highly air-permeable for filling or breathing of the goods - ensures perfect protection of your valuable packed material. No Spillage As a result, the sack survives even rough local handling conditions. Minimum sacks damage or breakage during filling, conveying, loading and transport. Water resistant Withstanding water and humidity, the sack keeps its full strength in all conditions - even when lying on damp ground, exposed to rain or to high air humidity. Made from water- resistant polypropylene, the sack is not affected by any form of moisture, unlike paper. This does not mean that sack is always completely watertight. In some applications the sack has to be produced with micro-perforations to give it the necessary air permeability. UV degradable The sack is made from polypropylene, which is broken down by UV when exposed to sun for a long time.
