4 loop big bags

Four-loop big bags are made of laminated or non-laminated polypropylene fabric. These big bags may be provided with inner polyethylene liner (40 to 100 microns in thickness), which protects the products against external moisture. The seams of big bags may be sealed for protection of products against dust and chipping. Big bags are designed for packing, storage and carriage of grain, fertilizers, hazardous and non-hazardous chemicals, also the products for food industry. When lifting, the weight force is distributed among the four loops.

Q-BAG type big bags 


          1pav. "Q-bag" type big bag

 

Big bags with partitions inside (Fig. 1) are big bags of a special design with internal partitions in the corners, which prevent the bag from bulge during the pouring process, ensure a stable form and do not allow the bag to incurve. Such big bags require less space, and the carriage costs compared to standard big bags are reduced considerably.
