ISO 23560:2008(en)–Woven polypropylene sacks for bulk packaging of foodstuffs
With the removal of trade barriers between nations, there is a need for an International Standard for the packaging, transportation and storage of foodstuffs such as cereals. Polypropylene (PP) sacks made from woven fabric are an ideal choice for the packaging of foodstuffs. Such sacks are produced from food-grade polypropylene and ensure the mechanical strength needed for storage and transportation.
This International Standard describes the construction of the sacks, their dimensions and test methods suitable for ensuring the long-term storage and transportation of foodstuffs in the sacks.
This International Standard specifies the general characteristics, requirements and methods of test for woven polypropylene (PP) sacks. It is applicable to woven PP sacks, having a capacity of 50 kg or 25 kg, intended for the transport and storage of foodstuffs, such as cereals, sugar and pulses.
