Coffee bag

Two Brazilian coffee bags

A Coffee bag is a bag used for shipping and storing coffee

Bulk coffeeEdit

Large bulk bags or sacks are usually used for used for storage and transport of coffee beans. Traditionally it is made of jute and has a content of 60 kilograms (130 pounds), this type of bag originated in Brazil and became a worldwide standard.[1] It also became a measurement unit to this day, for example FAO's statistics on coffee production are expressed in 60-kg bags.[2]

Jute fibers are treated with mineral oil (used to be whale oil) to improve Spinnability, which raised questions about coffee contamination from these hydrocarbons, but further studies showed it to be infinitesimal.[3] Bags with synthetic fibers (woven or non-woven) are commonly used now.

Once used, these decorative bags can be recycled or upcycled for many uses including in clothing.[4]

The 60 kg sack is starting to be replaced by huge polypropylene or polyethylene bags, such as the flexible intermediate bulk container. These are increasingly used for coffee exports - especially from Brazil.[5] Intermodal shipping containers are common for international shipping.

Consumer packagingEdit

Pre-packaged bags of coffee beans and ground coffee at supermarket

Smaller bags are used by consumers for coffee beans or for ground coffee. Multi-layer, high graphics, bags have largely replaced steel cans (tins) for consumer ground coffee. There is a tendency for pressure from carbon dioxide to build up in these barrier bags. Special pressure relief valve have been developed to relieve the pressure without letting atmosphere into the bags.[6][7][8] Valves are either heat sealed or attached by adhesive. The bags are not readily recyclable but compare favorably in life-cycle studies with metal cans on broader issues.[9]

Several other types of consumer bags are also in use. For example, small single-cup bags have been developed: similar to the more common tea bags. Larger porous bags (paper or nonwoven fabric) have also been used for brewing a full pot of coffee. Some allow for multiple layers of different coffees for special tastes.[10]
