This piece is informative on the reasoning for vacuum packing. But not just that; the benefits someone derives from having done it as well. Up front, let's explain the term vacuum packaging! We shouldn't take it as given that because a certain term gets banded about everyone knows what it means - maybe they don't! It goes like this: we wrap the item to be vacuum packed in cling film which is heated, then as it cools the trapped air is completely evacuated. So we've answered the question: 'what is it?' Now, what's it good for? Pleae don't just consider food when you hear the term vacuum packaging. Though it's usually in that connection that most people hear of it. Items so packed are less liable to bruising. Products live beyond what would have been their 'sell by date' in other ways... For instance with bacon where taking oxygen and nitrogen, all that from the air helps keep your bacon fresh. Another of our favorite foods, cheese, would likewise deteriorate from mould growth and it would get too tough and dry to use without being vacuum packed. Vacuum packaging is reckoned generally to prolong shelf-life by 3 to 5 times. As might readily be expected, in service industries like the hotel and catering industries which deal to a considerable extent with food preparation, vacuum packing very much comes into its own. For these purposes a vacuum packing machine may be used. Thee are rough and ready techniques akin to vacuum packing used domestically but its best simply to break out the vacuum packer and use it. Or buy one if we can the budget allows. But it's not just a matter of air-exclusion, there's also an improvement in hygiene at the same time. The thing is that all that we've been speaking of results in less food spoilage, The endless heeaps of food thrown away continually result in massive amounts of methane, carbon dioxide, all of that... Thus if our experts are to be believed this is a significant contribution to global warming. It means the vacuumm packer does play its part in reducing this phenomenon Thus the answer to why vacuum pack? may seem to be to make food last longer... True enough we use vacuum packaging for food purposes but it has many industrial uses too it must be said. A vital technology today.
