Self-adhesive strip for re-closing a package after first opening has front and back layers that are joined by a weak adhesive for automatic separation when the package is folded or rolled

摘要

The self-adhesive strip (5), designed to re-close a package once its top has been folded or rolled following first opening, has a back layer (6) that adheres more or less permanently to the pack, and a front layer (9) that is attached to the back layer and can be partially detached from it to adhere to the package and hold down the folded or rolled top. The joint between the front and back layers of the strip is slightly adhesive and the partial separation is produced automatically when the package top is folded or rolled. In addition, the front layer of the strip has a tab (10) that can be gripped to facilitate manipulation.
