Abstract: A packaging article includes an outer, intermediate, and inner paper plies. A first adhesive layer is disposed between the inner and intermediate paper plies for gluing the inner paper ply to the intermediate paper ply. A second adhesive layer is disposed between the intermediate and outer paper plies for gluing the intermediate paper ply to the outer paper ply. The first and second adhesive layers overlap and are coaligned. The outer, intermediate, and inner paper plies are adjoined to form a multiwall structure, wherein the first adhesive layer and the second adhesive layer are coaligned with each other on the multiwall structure. The first adhesive layer comprises a first plurality of adhesive spots and the second adhesive layer comprises a second plurality of adhesive spots, wherein the adhesive spots of the first plurality of adhesive spots do not overlap with the adhesive spots of the second plurality of adhesive spots.

Abstract: A method for sealing a thermoplastic bag includes forming a first fold in a top end of the bag; forming a second fold in the top end that includes the first fold; folding the first fold to form a first portion of the first fold and a second portion of the first fold, the second portion of the first fold is folded onto the first portion of the first fold; and heat sealing the first fold and the second fold to each other and to a portion of the bag that faces the first fold, the heat sealing including applying hot air to the bag. Preferably the second fold has a height that is less than a height of the first fold such that the forming of the second fold folds the first fold to form the first and second portions of the first fold.

Abstract: A reclosable pour-spout packaging, such as a bag, has a top handle and can be manufactured on a form-fill-seal machine. A reclosable structure can reversibly close and open the interior of the packaging. The handle can comprise a cut extending through the packaging. An additional seal area in the packaging can provide support so that a punch and die assembly can punch or cut the handle in the additional seal area. Additionally or alternatively, a laser device, a blade, a knife, or another cutting tool can form the handle in the additional seal area. The additional sealed area can provide stiffness for carrying the packaging and also prevent access into the packaging where the handle is made. The additional seal area can be positioned below the top seal of the packaging so that less material is used for the handle.

Abstract: An automated processing system, particularly for use in biotechnology, which is modular in construction and allows for a wide variety of instruments to be inserted and/or removed without having to reprogram the system and methods of using such a system. This may be called “plug and play” functionality. The system may be portable without disassembly and have a generally vertical arrangement so as to utilize less useful lab space than a horizontally arranged system.
