4 Loop Big Bags

As a specialized Big Bag (Big Pack, FIBC) manufacturer with experience and expertise, QUP offers Big Bags (internationally also called Flexible Intermediate Bulk Container or FIBC for short) that meet the highest demands. What all Big Bag (Big Pack, FIBC) variants have in common is that they offer a cost-effective and simple packaging option for transporting and storing a wide variety of bulk goods. Thanks to the PP fabric mostly used in production, Big Bags are robust, flexible and can be made dustproof or breathable if required.

4 Loop Big Bags – i.e. FIBCs with 4 loops – are among the most common flexible bulk containers and are used in many different industries. To be able to meet your needs, QUP offers common 4 loop Big Bags in different versions:

  • Standard Big Bags with 4 loops

QUP standard Big Bags are a simple but particularly practical solution for storing and transporting bulk goods. By default, the flexible containers are open at the top and have a flat bottom. They are used particularly often as construction and waste big bags. Production is also possible under so-called clean room conditions – this enables the use of the standardized, 4-loop Big Bags as so-called food grade (food quality) Big Bags in the food or pharmaceutical industry.

  • Dimensionally stable Big Bags with 4 loops

In addition to particularly flexible standard Big Bags, QUP also offers special, dimensionally stable Big Bags. These are equipped with partitions on the inside so that they remain dimensionally stable when filled. In addition, the special construction guarantees that dimensionally stable Big Bags can be easily filled right up to their corners. Easier filling can help to drastically reduce transport costs.

Just like standard Big Bags from QUP, rigid bulk containers can also be designed as conductive Big Bags, UN (ADR) Big Bags or asbestos Big Bags.

During the filling and emptying process of certain products, friction of the filled material can lead to electrostatic charges on the surface of big bags. This can cause an explosion when filling or unloading if the big bags are not grounded. To prevent this, type C conductive big bags must be used for the safety of people and equipment in the vicinity of the filling or unloading area.
