Metal packaging for food.
Metal packages are made of thin sheets, most often aluminum, steel white, black and galvanized as well as tin and aluminum foils. Barrels are made of steel sheet, konwie, buckets, kanistry, boxes, containers, tubes and cans.
Barrels are used for packing liquid or crushed solids, propellants, lubricating oils and chemicals (detergents, chlorinated lime, fenol itp.). Most of the barrels are reusable packaging.
Metal cans are used as packaging for sterilized or pasteurized canned food. They are made of tinplate, galvanized or aluminum covered with a colorless and usually acid-resistant resin varnish..
Cans and combination boxes, cardboard and sheet metal closed with a pressed or put on lid, are made of galvanized or thin pressed steel sheet, as well as aluminum foil and recycled cardboard. They are used to pack seasonings for soups, candy, cocoa etc.. Sometimes these packages have an aluminum foil sealing membrane, which additionally secures the content.
Tubes are made of tin and aluminum, serving as a packaging for mayonnaise and food concentrates. Aluminum foil is used to make molds, serving as a unit packaging of frozen delicatessen products and frozen sets of ready meals.

Aluminum foil is also used to pack processed cheese, confectionery, food concentrates, etc.. Due to the low mechanical resistance of these packages, aluminum foil is often combined with other materials, np. with plastic films, obtaining a multi-layer packaging.
