The present invention relates to a container for liquid containing food products, manufactured by press forming of a polymer coated fiber based substrate, said container comprising a bottom portion, a sidewall portion and a top flange portion, wherein said press forming has resulted in the formation a plurality of creases extending in a direction from the bottom portion to the top flange portion and further across the top flange portion. The container comprises an indentation pattern (130, 140, 150, 160, 170, 180, 190a, 190b, 200) formed at a creased inner surface of said sidewall portion and/or at a creased top surface of said top flange portion, said indentation pattern preventing migration of liquid from a liquid containing food product in the container along said creases. The invention relates also to a method for manufacturing such container.

A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

A clamshell packaging for airtight packaging of foodstuff includes a tray folded out of a single sheet. The tray has at least two adjacent pool parts, each pool part having a bottom wall and upstanding walls arranged around the circumferential edge of the bottom wall. The adjacent pool parts are hingedly connected to each other along an upper edge of a respective upstanding wall, so the adjacent pool parts can be hinged on top of each other to form a closed box. A circumferential, horizontal flange is arranged to the tray to at least some upper edges of the upstanding walls. A plastic barrier foil is arranged in the pool parts and extends onto and substantially covers the flange. The flange includes a seal zone extending along the length of the flange. The seal zone is line symmetrical along the hinge line at the upper edge of the connected walls.

Described are a machine and a method for forming containers from blanks, including a plurality of shaping hoppers, an endless conveyor which defines a feed path and on which the hoppers are mounted in succession and a plurality of pushing elements which are movable in such a way as to follow the respective shaping hoppers along at least a stretch of the feed path and which have a to-and-fro operating movement towards and away from the respective hopper along a direction transverse, preferably perpendicular, to the feed path. The machine also includes folding means disposed along the feed path downstream of the pushing elements and configured to produce, respectively, a top closure and/or a bottom closure of the tubular blank.

The invention relates to a heating module and a primary reflector for a heating module of a heating duct of a molding machine for producing containers from preforms, in which preforms made of thermoplastic are heated, which is provided between tubular heating units arranged in parallel and one over another on a side wall of the heating module and the side wall and consists of ceramic material, and is characterized in that the primary reflector is connected via a dovetail connection to the side wall, wherein a connecting region in the form of a dovetail is formed in each case on the reflector, which is fixable in each case with a clip made of steel, in particular spring steel, fastened on the side wall, having dimensions adapted to the dovetail.

The present invention relates to a web of fibrous cellulosic material derived from wood pulp, said web being suitable for three-dimensional moulding to form a packaging product, wherein the web comprises >40 wt % of soft wood chemical pulp and at least one strength enhancement agent, wherein the web has a grammage less than 400 g/m.sup.2, and wherein the cellulose fibers of said soft wood chemical pulp comprise a fiber curl of >9%.

A coating process of a segmented paper pulp bottle blank includes: S1, placing a film raw material into a bottle blank to be coated; S2, folding an upper edge of the film raw material to fix the upper edge onto a mouth of the bottom blank; S3, placing the bottle blank fixed with the film raw material into a coating mold; S4, placing a hot-air blowing pipe into the bottle blank; and S5, sucking air by the coating mold to absorb the bottle blank onto inner cavity walls of the coating mold, blowing in hot air by the hot-air blowing pipe to make the film raw materia1, after being heated and softened, to be expanded and adhered to the inner wall of the bottle blank, and finally opening the coating mold to take out a finished product. Moreover, a production process of a segmented paper pulp bottle is provided.
