Metallpakendeid

Metallpakendeid is a category of packaging materials and containers made primarily from metal, including aluminum, tinplate steel, and stainless steel. Metal packaging is used to protect contents from moisture, light, oxygen, and contamination, while providing mechanical protection and durability during storage and transport. Common forms include beverage cans, food cans, aerosols, jars with metal lids, and closures for bottles and tubes.

Metals offer high barrier performance, rigidity, and space efficiency; aluminum is lightweight and corrosion resistant; tinplate steel combines steel's strength with a tin coating to improve formability and corrosion resistance; stainless steel is used for specialized products. Metal packaging can be printed with graphics and labels, and is compatible with heat sterilization and certain filling processes.

In manufacture, metal packaging is produced by forming processes such as deep drawing, ironing, and drawing-and-iron operations for cans, as well as extrusion and stamping for closures and ends. Coatings and lacquers are applied inside to protect contents and ensure safety, and printing is applied on outer surfaces for branding.

Applications: Food and beverage dominate the market, including ready-to-drink beverages, canned vegetables, and pet foods; aerosols for personal care and household products; pharmaceutical and cosmetic containers; industrial packaging for chemicals and hardware.

Recyclability and environmental aspects: Metal packaging is highly recyclable; recovered material can be re-melted and remanufactured with relatively low energy use compared with virgin metal. Recycling infrastructure and consumer sorting influence recovery rates, while lightweighting and design for recycling are current industry trends. End-of-life management and regulatory compliance are important considerations.
