kartong

Kartong is a term used in several Scandinavian languages, notably Swedish and Norwegian, to denote cardboard or a carton made from paperboard. It refers to rigid, paper-based materials used for packaging, displays, and related products.

Two main forms are used in packaging: solid cartonboard (paperboard) and corrugated cardboard. Solid cartonboard is a dense, smooth sheet used for consumer packaging and printing; corrugated cardboard consists of a fluted middle layer between two linerboards, giving higher strength and cushioning for shipping.

Production and properties: It is produced from wood pulp or recycled fibers; sheets are formed, pressed, and dried. Coatings or laminates may be applied for moisture resistance or print quality. Quantities are described by grammage (g/m²) for paperboard and by caliper (thickness) for cardboard. Kartong is lightweight, rigid, recyclable, and widely used, though moisture sensitivity and printing limitations vary by type.

Uses: Packaging for food, electronics, cosmetics, and other goods; shipping containers; point-of-sale displays; craft and art projects. Food-contact suitability depends on coatings and compliance with hygiene standards.

Environmental and safety aspects: Kartong is commonly recycled; post-consumer material can be re-pulped and reused in new packaging or products. Recycling efficiency improves when it is kept dry and free from non-paper contaminants like plastics or waxes. Some kartong products use barrier coatings or laminates that affect recyclability and require proper disposal.
