Selvforseglet

Selvforseglet is a Danish term meaning self-sealed. It describes objects or packaging that can close and seal themselves without a separate sealing action by the user. The seal is achieved through an integrated mechanism, such as an adhesive strip, a heat-activated seal, or a lid that creates a tight closure when engaged. The concept is common in packaging where ease of use and tamper evidence are important.

Common forms include self-sealing envelopes and mailers that use an adhesive flap that sticks when pressed; self-sealing plastic bags with a pressure-sensitive seal; and containers with caps or lids that form a seal through an internal gasket or mechanism. These designs aim to protect contents and indicate if the package has been opened.

Uses of selvforseglet packaging span mail and shipping, food packaging, medicines and medical supplies, and consumer goods. Tamper-evident features are often integrated to help verify whether a package has been opened since sealing.

Advantages of selvforseglet packaging include convenience, reduced need for separate sealing steps, and potential tamper evidence. Limitations can include reduced resealability, reliance on specific materials or equipment for manufacturing, and environmental considerations due to multilayer or non-recyclable components. Costs can also be a factor depending on the design.

In Danish, the term emphasizes self-contained sealing capabilities rather than requiring additional tools or actions after purchase. See also tamper-evident seals and adhesive-seal packaging.
