blikken

Blikken are metal containers used for packaging and storing food and beverages. In Dutch, the term refers to cans made from tinplate or aluminum, designed to protect contents from air, light, and moisture and to extend shelf life. Blikken are widely used in the food industry for products such as vegetables, fruit, meat, fish, soups, and ready meals, as well as for beverages in some cases.

Construction and materials vary by type. The body is typically formed from a metal sheet and joined at a seam, with ends crimped or sealed onto the body. Inside, an protective coating or enamel prevents corrosion and interaction between the metal and the contents. Modern cans often use aluminum or steel with polymer or epoxy interior coatings. Easy-opening devices, such as pull-tabs or stay-on tabs, were introduced to improve convenience, while specialized designs exist for aerosols and other products.

History and use. The concept of preserving food in metal containers began in the early 19th century, with tin-coated iron cans emerging in Europe after the development of commercial canning. The technology enabled longer transport and storage of perishable goods and played a significant role in food supply for military and civilian markets. Over time, manufacturing improved to reduce metal use, enhance sealing, and improve recyclability.

Environmental and cultural aspects. Blikken are highly recyclable in many regions, with steel and aluminum recovering well through recycling streams. In everyday language, the term also appears in historical and commercial contexts, reflecting its enduring role in packaging and logistics.
