Vacuum sealing is a method of wrapping in which the air is removed from the product before it is sealed. This process entails placing products in plastic film packaging, extracting air from inside, and closing the box (either manually or automatically). Shrink film is occasionally used to ensure that the contents are tightly sealed. Vacuum seal bags are used to remove oxygen from a container to improve the shelf life of foods while also decreasing the quantity of the items and packages in flexible packaging forms.
Vacuum packing decreases atmospheric oxygen, restricting aerobic bacteria or fungal growth and reducing volatile component evaporation. It’s also used to keep dry items, including cereals, almonds, meat, cheese, smoked salmon, coffee, and snack foods fresh for a long time (crisps). Vacuum packing could also keep fresh items such as veggies, meats, and liquids for a shorter period because it limits bacterial growth.
Vacuum Seal Bags Come in a Variety of Styles
- Pouch Bags: Precut pouches with external suction vacuum sealers are laminated or vacuum pouch bags. Pouches normally have a thickness of 3 to 5 mils.
- Zipper Bags: These reusable grocery bags are ideal for storing leftovers and cutting vegetables during dinner prep.
- Vacuum Sealer Bags: It’s a pre-cut vacuum-sealed bag that can be sealed according to the volume of the contents inside.
- Sous Vide Bags: Sous Vide is a slow cooking method in which food is cooked at a consistent temperature for an extended period over a low flame. This is cooked with the plastic bag still attached. Sous Vide bags can withstand high temperatures for lengthy periods.
On both a residential and commercial level, storing food in vacuum seal bags is fairly frequent and convenient. There are vacuum storing bags that can be refrigerated or frozen, then thawed and heated. Food storage bags should be made of FDA-approved, high-quality thick plastic that can endure both warm/cold temperatures. When heated, they should not melt, and when frozen, they should not break and tear.
