In this article, we will not only tell you why people vacuum pack but also tell you many advantages of doing so.
First of all, we'd better define what is vacuum packaging! It's too easy to assume that everyone knows what they're talking about, especially in terms that are used almost every day. So make sure we're all on the same page: in vacuum packaging, first, heat the transparent plastic film, and then cool it around food or other items, excluding some or almost all of the cooling air.
So we have answered the question, "what is this?" Now, what's the use of this? A person is widely exposed to vacuum packaging, but not limited to food retailing: in greengrocer or supermarket fruit and vegetable areas. Such packing is not easy to bruise.
The shelf life is also extended in other ways. Like bacon, removing oxygen and nitrogen from the atmosphere can keep you fresh. Similarly, in cheese, air entering the product will make the cheese dry faster and moldy. It is generally believed that vacuum packaging can extend the shelf life by three to five times.
Hotel and catering
Vacuum packaging is also widely used in hotels and restaurants, where food is prepared and packaged in a transparent film until eaten. For these purposes, a vacuum packaging machine can be used. At home, we've come across similar procedures for preserving food through temporary "vacuum packaging" rather than just cold storage. But it's not just about getting rid of the air, it's also about improving health.
It is important that all of the above measures reduce food waste. Millions of tons of food dumped each year because of decay release a lot of methane and carbon dioxide. This has exacerbated global warming, so this humble vacuum packaging machine plays an important role in reducing this modern phenomenon, which has an impact on climate change.
