The present invention refers to a container precursor, comprising a composite sheet which comprises a) an outer polymer layer, b) a colour application, c) a carrier layer, and d) a barrier layer;
wherein a wall of the container precursor comprises a first wall region and a second wall region. The invention further refers to a closed container, obtainable from the container precursor; and to a closed container having the above composite sheet, the first and the second wall region.

A system and method of at least partially forming reinforced packages. The method comprises moving a construct in a machine direction on a construct conveyor. The construct conveyor can comprise a primary lug belt with a primary lug, the construct can be disposed on the primary lug belt, and the moving the construct can comprise moving the primary lug belt in the machine direction to push the construct in the machine direction. The method further can comprise positioning a liner on the construct conveyor so that the liner at least partially extends over the construct and moving the liner in the machine direction on a secondary lug belt of the construct conveyor. The secondary lug belt can comprise a secondary lug and the moving the liner can comprise moving the secondary lug belt in the machine direction to push the liner in the machine direction.

An apparatus successively makes plastic bags each of which includes an end surface provided with a protrusion, without specially supplying a web of bottom gusset material. A first web of panel material is folded along a first folded line at a position adjacent to a side edge of the first web, while a second web of panel material is folded along a second folded line at a position adjacent to a corresponding side edge of the second web. A first folded portion is formed in the first web. There exists a distance between the side edge and the first folded line, which is larger than twice a distance between the corresponding side edge and the second folded line by a predetermined distance, after being folded. The end surface is formed by the first folded portion, the protrusion being formed by the predetermined distance.

The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

A method and apparatus are disclosed for forming containers. The containers may be cans, including composite cans. The apparatus may include a cylindrical mandrel and a blank may be formed into a cylindrical tube around the mandrel. Rotational apparatuses may engage portions of a blank that may be in a flat configuration and may rotate the portions around the outward cylindrical surface of the mandrel. Free edges of the tubular blank may be sealed by a sealing strip that may be T-shaped in cross section. A cup may be installed in an end opening, such as a bottom end, of the cylindrical tube. The cup may be sealed in the end opening by a seaming process using a seaming apparatus.
