Abstract: The present disclosure relates to a paperboard sealing disc for use in a packaging container, comprising a peripheral edge portion surrounding a tear-open part having a push-tab and a pull-away part. The tear-open part is delimited from the peripheral edge portion by a first cutting line in the first side and by a second cutting line in the second side. Said first cutting line being provided at a distance d1 from said sealing disc outer edge, and said second cutting line being provided at a distance d2 from said sealing disc outer edge. The push-tab is at least partly delimited from the pull-away part by a folding line. At the push-tab d1>d2 and at the pull-away part d4>d3. Furthermore, d1 at said push-tab is substantially the same as d4 at said pull-away part and d2 at said push-tab is substantially the same as d3 at said pull-away part.

Abstract: The present disclosure relates to a transport closure (1) for use in a packaging container (10) for bulk solids. The transport closure includes a laminate of a first layer (2) and a second layer (3). The first layer (2) is delimited by a first layer peripheral edge (4) and the second layer (3) is delimited by a second layer peripheral edge (5). The second layer (3) comprises or consists of a weldable material and the first layer (2) has higher tear strength than the second layer (2). The first layer (3) is provided with a weakening line (6) defining a pull-tab (7) in the first layer (3) and having a first and a second base point (6a,6b). The base points (6a,6b) are arranged at a base end (7b) of the pull-tab (7), opposite to a gripping end (7a) of the pull-tab (7).
