The ascendancy of food manufacturers in using vacuum sealers to prevent spoilage of their products that has to undergo long distance transits, and a way to prolong its shelf life, has modernized the way packing is done by most homeowners. This technique of removing air from the package prior to sealing preserves a foodstuff from spoiling because it not only hinders the growth of bacteria and mold, It also keeps a foodstuff fresh on account that oxygen is the reason why food gets spoiled or go stale. Another prevalent advantage of a vacuum sealed packed foodstuff is that it prevents raw meat, poultry and even vegetables from dehydration and oxidation when place in the freezer (freezer burn).
Before these sealers were huge and massive and only food manufacturers are able to have it, just like the computers of old which were huge and massive and not very many people can afford to buy it.

These portable vacuum sealers and were useful at home if you want to repack items in large quantities or if you have cooked plenty of food, you can also put them into bags for single meals.

But least you will think that once sealed there is no more need to maintain it, remember that sealer bags are airtight, but small leaks can develop when food is stored in them of a long time- several months and even more. Oxygen is the food spoiler and if just a small hole is present in the bag, it will surely harm your stored food. The best way to prevent this is to use bags that are puncture resistant like Mylar bags which are made of polyester resin laminated with aluminum foil which serves as an extra barrier. This is ideal if you plan to store your food for a long time.
