Vacuum Bag

A vacuum is not only used for cleaning the house.  In fact, there are other uses for a vacuum that you may even find astounding.  A vacuum can be used to clean almost anything off the floor, wall corner or ceiling.  But most interestingly, with the use of vacuum bags, a vacuum can turn out to be one of the best accessories used in storing items ranging from food to clothing.

Put in the Bag

A vacuum bag is essentially an item made of rubber-coated fabric and is open at one end but can be sealed after all the air has been sucked out of it.  This is especially useful when you want to store things in them.  And it’s so easy, anybody can do it; just pop in whatever you want stored into a vacuum bag, plug in your vacuum and suck the air out of the bag until it is air tight.  You can then seal the open end and you have just created the perfect storage for items like clothes, blankets, etc.  It also helps as a space saver because by sucking out all of the air in a vacuum bag, you can greatly reduce the space inside the bag itself.  Ever seen those pillows that are totally flat in a bag and they get fluffy again once you open those bags?  That is a vacuum bag stored pillow.

Other Functions

One can also use a vacuum bag to store food, such as cereal, nuts, and dried meats.  This is a great way to save space in your fridge (although you will not want to flatten your food items too much) and also to preserve some of the food that you have so that it won’t spoil too quickly.  Food will eventually spoil but if you deprive the space around the food of bacteria by using a vacuum bag to create an air tight environment, you can slow down the spoiling greatly.  Another thing that a vacuum bag is good for is lamination.  Laminating materials is one of the hardest things to do especially if you want to laminate materials that are of irregular shapes and sizes.  The vacuum bag is used to enclose whole objects.  Then a vacuum is used to draw out all the air because a vacuum is essentially a pump.  Once the air is out, it holds the plastic parts of the vacuum pack together and a pre-applied adhesive can start to cure and hold it into place. 

Lamination?

You might ask why people would laminate things in the first place.  Well, this is especially important for manufacturers who create different molds to make their products, such as flat panels in construction.  Those flat panels are not made flat instantly.  When they are made, they are not entirely solid yet and need time to dry and harden.  To help make this process simple and, a vacuum bag can be used to laminate it and hold the mold in place.  This is important because if there are any objects that are made with irregular shapes, a vacuum bag is the best way to laminate those objects without disturbing the shapes.  A flexible membrane (vacuum bag) is used to coat the mold.
