packning

Packning is a Swedish noun that broadly refers to the act of packing or to materials used for sealing and protection. In everyday language, it covers both the preparation of goods for transport or storage and the materials employed to protect or seal items.

In logistics and shipping, packning describes the process of packing items for shipment: selecting containers, adding padding and cushioning, sealing with tape, and labeling. Choices depend on item fragility, weight, humidity, and destination. Proper packing aims to prevent damage, meet carrier requirements, and optimize space.

In product packaging, the term is related to forpackning, but packning can refer to the interior packing or the sealing materials used inside packages to protect contents. Packaging design focuses on protection, usability, and sustainability, including recyclability and material efficiency.

In engineering and machinery, packning refers to sealing materials such as gaskets or packing around a shaft. Typical materials include rubber, PTFE, or graphite, and configurations include sheet gaskets, ring gaskets, or braided packing. They are used in pumps, valves, flanges, and pressure vessels to prevent leaks.

In mathematics and computer science, packing concepts appear as packing problems, where objects are arranged within a space to optimize density, and data packing refers to compact representation of information.

The term is common in Swedish industry and trade, with förpackning often used for consumer packaging, while packning more often denotes the sealing material or process.
