The principle of operation is as follows: from the inside, air can be pumped out with both special equipment and at home without it. Once the process is completed, the edge of the film is sealed and the seam becomes airtight.
The main objective of packaging is to prevent oxygen from accessing the product. This will prevent the process of fermentation, decay and drying, bacteria will not be able to develop in such an environment.
The product is protected from moisture, which allows you to maintain a presentable appearance, aroma and freshness.

Vacuum film can be top, bottom and type Flow-pack. The first option is suitable for sealing the packaging, and the second for molding. Available in rolls of different widths, lengths and film thicknesses. These indicators characterize the density and tear resistance.
Polyamide and Polyethylene Used for the production of vacuum bags. It shrinks while pumping air, taking the form of the product inside. This option is perfect for home use, as it is versatile and practical.
Corrugated Vacuum Packaging It is used in enterprises where there are special machines. This is a multilayer material, which consists of polyethylene and polyamide, alternating with each other. Thanks to this surface, the machine can completely pump air out of the package. Such bags are also called embossed or corrugated.

Most garment packages have a cap with a flap. Air can be pumped out with a conventional vacuum cleaner at low power. When the parcel becomes smooth and solid, the valve can be closed, and the package can be sent to a shelf in a cabinet or put in a suitcase for a trip.
there is compression bags in which there is no valve and therefore air is released by twisting the packaging. Then it is enough to close the lock tightly, and things will be hermetically stored. It is extremely important before this to check the accessories, if possible, hide it inside the clothes so that it does not damage the packaging.
If it is necessary to pack food products, while there is no vacuum, can extract air from packaging at home. Vegetables need to be washed and dried or peeled, the meat should be separated from the bones, that is, remove all unnecessary. The food is packed in a bag with a ziplock, which must not be completely closed, leaving a small hole. Then place the package in a container of water, it squeezes out the air completely, after which you can close the fastener.
