the packaging of coffee beans has very important role to play when it comes to the production process by virtue of its function in the control and preservation of the aroma as well as the gas created by the process of roasting. due to this, generally bags with degassing valves are used in the packaging of coffee beans. these valves allow carbon dioxide to release at the same time preventing the ingress of moisture and oxygen in the package that would affect the flavour. the pioneering aspect of cia&rsquos coffee beans packaging answer is to incorporate special patented flat degassing valves that which offers the use of common packaging machines with constant paper rolls, eliminating the entire procedure of plastic valve application to the packaging as their films born with the flat valve already integrated. in the production process, the packaging of coffee beans is extremely important stage since the roasted coffee deteriorates speedily when in contact with the air. the oxygen in the environment active the process of oxidation of the coffee and makes its aroma wane quickly. due to this, after roasting, the coffee must be packaged as soon as possible. however, this is made complicated because of the gas pressure within the toasted bean that, while in the ground coffee is melt in a span of few hours, in the beans it get lost over many weeks. this demands the application of the valve usually a plastic one to the package, with additional processing stages to be introduced in the process, with the following costs in terms of equipment and time. however, the use of cia&rsquos packaging film for coffee with flat valve and the packaging machines, allows reducing considerably the processing costs and time. &bull no need to alter the packaging machine for the use with usual plastic degassing valves &bull no need to by optional accessories for instance the system of feeding for the application of degassing valves, costly and which slows down the process of manufacturing &bull size switch is instant and needs no alteration to the packaging machine furthermore, the use of the film, which has flat degassing valve, has a lower overall production cost as compared to the traditional film with plastic valve. thus, it allows a continuous saving throughout the entire process of packaging. source of information httpwww.ciasrl.itengnewscoffeebeanspackagingflatvalve.html
