摘要： Cup made of paper material having a fillable interior space formed by a shell and a base. The base via a skirt at the lower end of the interior space is fastened in a substantially liquid-tight manner to the shell, and a lower periphery of the skirt forms a footprint for the cup. The cup has an external shell composed of a planar blank of paper or paper-like material. Longitudinal edges of the blank are connected to one another in an overlap region so that the external shell forms a sleeve. The external shell has a frustoconical shape having a first cone angle and, except for the overlap region, from the predefined spacing to the lower end is configured in a single ply. The shell, from the predefined spacing to the lower end, at least in portions tapers more heavily than in the region above the predefined spacing.

摘要： The invention relates to a polygonal container comprising a tubular polygonal body (10) with an even number of flat faces (11) numbering more than four, which is formed by a strip of corrugated cardboard (19) rolled up at least two full turns and adhered to itself by means of lines of glue (30) transverse to the channels of the corrugated cardboard, forming a multilayer wall (13); a base body (20) defined by a base panel of cut and folded stiff double-faced corrugated cardboard (24) attached around an end portion of the tubular polygonal body (10). The method comprises forming the tubular polygonal body by means of rolling the strip of corrugated cardboard around a polygonal rotary drum (51) and subsequently attaching to a base body (20).

摘要： A method for manufacturing a paperboard bottle and spiral-wound paperboard bottle. The bottle has a tubular body portion, a shoulder and neck portion having a circular cross-section narrowing from the body portion to a circular mouth. The paperboard bottle is a liquid packaging board having thermoplastic polymer coating on both sides. The method includes cutting a planar elongated blank from a packaging board sheet. Protecting exposed cut raw edge of the first longitudinal edge against absorption of liquid. Securing the first end of the blank to a rotatable mandrel having a rotation axis (x) and an outer shape corresponding to the shape of the bottle. Rotating the mandrel to wind the blank spirally onto the mandrel, so that the longitudinal edges overlap applying heat-sealing energy and pressure, onto the overlapping longitudinal edges to form a bottle with hermetically sealed spiral seam and removing the mandrel from inside the bottle.

摘要： A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

摘要： A wound package construct includes a first wound strip of package material that establishes an inner liner layer, a second wound strip of material that establishes an intermediate bodystock layer, and a third wound strip of material or cover strip that covers a seam formed by the wound bodystock layer but that does not cover all of the outer surface area of the wound bodystock layer. Therefore, the width of the cover strip is less than the width of the bodystock strip. As a result, the cover strip is not wide enough to cover the entire outer surface of the wound bodystock layer such that, after the cover strip is wrapped to cover the spiral bodystock seam, areas of the bodystock layer remain exposed between the two opposed length-wise edges of the cover strip.

摘要： The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.

摘要： The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate and one or more polymer coating layers extruded onto said substrate. According to the invention the packaging material includes at least one polymer coating layer containing polylactide and at least about 1 weight-% of terpene phenolic resin blended therewith. The invention further concerns a heat-sealed product package made from the packaging material, as well as uses of the resin as blends with polylactide in extrusion coating, for improving line speed and neck-in in extrusion, adhesivity of the coating to the fibrous substrate, and heat-sealability of the coating.
