　　Vacuum packaging is a packaging method that removes air from the package before sealing. This method involves (manually or automatically) placing items in plastic film packaging, removing air from the inside and sealing the packaging. Shrink film is sometimes used to cling to objects. The purpose of vacuum packaging is usually to remove oxygen from the container to extend the shelf life of food, and flexible packaging is used to reduce the volume of contents and packaging.

　　Vacuum packaging reduces the oxygen in the atmosphere, thereby limiting the growth of aerobic bacteria or fungi and preventing evaporation of volatile components. It is also commonly used to store dry food for a long time, such as grains, nuts, salted meat, cheese, smoked fish, coffee and potato chips. On a more short-term basis, vacuum packaging can also be used to store fresh food, such as vegetables, meat and liquids, because it can inhibit the growth of bacteria.

　　Vacuum packaging xxx reduces the volume of non food items. For example, clothing and bedding can be stored in bags evacuated with a household vacuum cleaner or a special vacuum sealing machine. Sometimes, this technique can be used to compact household waste, for example, collecting a full bag will be charged.

　　Vacuum packed products can be used in families by using plastic bags, cans, bottles or mason jars.
