A sealing apparatus for sealing a travelling packaging film. The sealing apparatus includes a first actuator, a second actuator, a first seal member, a second seal member, a slide rail arrangement, and a linkage coupled to the slide rail arrangement and connecting each of the first and second actuators to the first and second seal member. The first and second sealing members are actuated toward and away from each other between a disengaged position and an engaged position for sealing the travelling packaging film.

Sealing apparatus

The invention relates to a method for producing a packaging bag from a flexible film material () comprising the following steps: feeding of the flexible film material (); adding an additional material () to the flexible film material () and producing at least one stiffened partial region () from the additional material (), wherein the additional material () is hardened and forms the stiffened partial region (). The invention further relates to a device for producing a packaging bag, comprising: a film feeding device () for feeding flexible film material () and an additional material adding device () for adding an additional material (). The invention further relates to a packaging bag () comprising: a first transverse seal seam (), a second transverse seal seam (), a flexible partial region () and at least one stiffened partial region (), wherein the flexible partial region () is produced from the film material () and the stiffened partial region () is produced from an additional material () which was added and hardened to stiffen the packaging bag.

Method and device for producing a packaging bag from flexible film material and stiffened partial region and packaging bag

A method of verifying seal quality of a packaging material includes providing packaging material, and applying a thermochromic ink to at least one portion of the packaging material. The method also includes applying heat to the at least one portion of packaging material to form a seal, and inspecting the packaging material to determine the quality of the seal.
