The packaging industries are taking many changes in their techniques and working materials. These changes are for the betterment of the society and the human life. However, any of the steps which are introduced is finalized after the immense research and hard work of many people. If we have to move along with the time, or get advanced with the time, then adapting such changes is very necessary. We must respect any of such step and make it in our daily routine.

The vacuum bags are in the great demand in the market. The reason behind this in simple words is the safety of material packed in it. The material packed in any of the bag has to be saved from the outside environment. The environment contains many pollutants and other harmful gases which may affect the material. Also, if the food material is packed in it, and it comes in contact with the oxygen, it gets oxidized and this results in the loss of its nutritional value along with the taste. However, the moisture in the atmosphere may also get into the material which also results in loss of the material. In this case, the vacuum bags acts as a best protecting agent. The Sacchetti per sottovuoto (vacuum bags) basically inhibit the contact of material with the outside environment. This actually solves most of the problem. The contact with the air, humidity and other pollutants if not in contact with the material then the packed substance remains safe and as it is for a very longer time. This quality has impressed the packaging industry and so it is the most widely used technique. Either it be medicines, or capsules, or any chemical powder or liquid, any edible item or any household thing, everything is packed in the vacuum bags. The tea and coffee bags are also using the same technique in their packaging.

The other most widely used are the Buste trasparenti (transparent envelope). These envelopes are basically seen on the airport, railways and also in the offices. These envelopes are also widely found in the customs. Anything that is packed inside it can be seen through and identified easily. This makes the work fast and easy. The same thing is nowadays employed in the laboratories. The colored chemicals or any medicines or any sample, is packed in such envelopes can be identified easily using such envelopes. Also, if any especial notifications are needed, then it can be written over the envelope and used further.
