SWL / SF(Safe Working Load / Safety Factor)
These units indicate the maximum weight-bearing capacity of the FIBC related to a nominal weight and the linked safety factor. Especially for potentially hazardous goods these indications are vital as cracks have to be avoided under all circumstances. According to the EFIBCA standards the following categories are used: single trip, standard duty as well as heavy duty.
The characteristics of the good to be transported are the guideline for the choice of the so-called « dustproofing », which of course has to be a different one for coarse-grained material compared to fine, almost liquid powder. In case of doubt a liner (please also see liner types and standards), if possible, should be used here in order to avoid leakage of the contents
One way of enhancing the surface of the FIBC, providing it with more stability and protection, is the coating of the fabric. Coating is achieved by applying a thin film onto the PP strips, the thickness is indicated in gram per square metre (g/m2 or gsm). By means of coating the contents of the FIBC is protected from air and humidity. Moreover leakage of the product is prevented.
Due to the characteristics of the basic material (polypropylene) it is not advisable to store the FIBC in the sun without protection over a longer period of time. However, for limited periods in which sun radiation is unavoidable it might be useful to enhance the material with a UV stabilization so that the contents stays safely packed.
FIBC used in these parts of the industry are subject to extremely high requirements as the contents has to be protected according to the applicable laws and regulations. As a consequence the production and quality control of these FIBC are also very demanding in order to guarantee a maximum of safety.FIBC used in these parts of the industry are subject to extremely high requirements as the contents has to be protected according to the applicable laws and regulations.

(English) FIBC used in the food and pharma industries are subject to extremely high requirements since the goods have to be protected according to the applicable laws and regulations. There are several standards like HACCP, ISO 22000, BRC, AIB etc.
We audit each single producer and make sure that the company chosen for a project does not only boast the necessary certificate but lives up to the requirements in reality.
(English) The United Nations are author of the so-called « orange book » which are the guidelines for UN-certified FIBCs. According to orange book big bags are classified into various categories which then boast a code (e.g. 13H2: FIBC, woven from PP, coated) plus further codes concerning composition, production and other characteristics.
(English) The measurements of an FIBC are usually indicated as internal or external.
These indications differ from each other due to the sewing and assembly of the bags.
(English) Despite many industry standards FIBC are basically a tailor-made product which is designed according to the specific needs of the customer. The options which turn the FIBC into an individual product are manifold: e.g. filling/discharging spouts, swan-neck binding of the spouts, skirts, quick discharge devices, clips, ribbons, prints, markings etc.
(English) PE is a thermoplastic polymer often used for plastic bags and other common plastic products. For FIBC PE is mostly used in the liners (inner bags), cf. liner standards.
(English) PP is a thermoplastic polymer used to produce fabric and threads from which FIBCs are made. The fabric weight is usually indicated in grams per square metre (gsm).
(English) The Safety Factor is a test reference concerning the Safe Working Load, usually indicated as 5:1, 6:1, 8:1. For example SF 5:1 means that the bag can bear five times the indicated SWL before it cracks or bursts.
(English) This indication describes the recommended maximum weight for an FIBC or one of its components. Especially for potentially hazardous goods these indications are vital because leaks and cracks have to be avoided under all circumstances.
