Jumbo bags are made of smooth or polypropylene (PP) fabrics. The type of fabric used to produce the jumbo bag is selected based on the weight of the goods and the safe working load (SWL) and safety factor (SF). Jumbo bags are usually produced based on customer’s needs and for various uses and different types of lifting, filling, and unloading states. According to safe working load (SWL), safety factor (SF) and the type of goods, jumbo bags can be produced in a simple type with an entrance or open head and a closed bottom, which are suitable for most industries and goods. Or they are produced to transport and move food products and medicines that are made in isolated and completely hygienic workshops. A type of jumbo bag that are used to transport dangerous materials can also be produced based on specific properties developed by the United Nations.

Sanitary or food jumbo bag

These types of jumbo bags are producedjust for the pharmaceutical and food industries. The raw materials, fabrics, nylon layers, and … which are used in the production of these bags, and also the production workshop, are under special health and control supervision to prevent contamination of these types of jumbo bags.
