摘要:
A method for forming a naked collation package comprising a) providing an arrangement of packages individually wrapped in a filmic material; b) providing a naked collation film for nakedly wrapping said individually wrapped packages, the naked collation film comprising a polyolefinic core layer C, an inner sealing layer A on the inner surface of the naked collation film and a polyolefinic outer sealing layer B on the outer surface of the naked collation film, the material of the inner sealing Layer A being selected for sealing incompatibility with the filmic material of the individually wrapped packages under a specified sealing condition and heat shrinking condition, and the polyolefinic material of the outer sealing layer B being selected for sealing compatibility with B end for sealing compatibility with A under the specified sealing condition, wherein layers A and B are formed of the same or different materials and layer B comprises et least one polyolefinic polymer and a slip promotion component comprising less than 0.2% by weight of the layer of silicone and a non-silicone component in an amount exceeding 0.1% by weight of the layer; c) arranging the individually wrapped packages in an ordered configuration; d) arranging the naked collation film such that it at least partially surrounds the ordered configuration of individually wrapped packages; and e) heat shrinking the naked collation film by exposing it to the heat shrinking condition, causing, the naked collation film to shrink and closely surround the arrangement of packages, without being sealed to the packages. Naked collation film wrapped packages are also disclosed.

The present invention provides a duct molding method by which it is possible to improve the adhesion of a sheet. In the duct molding method of the present invention, a molten thermoplastic resin sheet is positioned between molds. Subsequently, the thermoplastic resin sheet (P) is absorbed onto cavity surfaces of the molds and the molds are closed. Thereby, a duct is molded.
摘要:
A multi-layer direct blow bottle in which a metallic layer containing a metal pigment having an average thickness of not more than 1 µm dispersed in a resin is formed at a position where it is visible from the outer surface side. This bottle is decorated metallic by extremely inexpensive means and gives an excellent metallic appearance stably.

A turbo duct is disclosed that includes a primary body having an inlet end, an outlet end, and an internal air passageway that communicates therebetween. An anti-crush ring is operably associated with at least one of the inlet and outlet ends. The inlet and outlet ends of the primary body are dimensioned to receive a cuff for connection of the turbo duct within an engine assembly. The anti-crush ring is situated on an outside surface of the turbo duct so as to form an intermediate anti-crush structure between the contact surfaces of the turbo duct and the cuff attached thereto. Also provided is a process for manufacturing the turbo duct.

Provided is a resin-laminated board that can improve the stiffness further while securing the weight and thickness reduction. A resin-laminated board includes a front-side sheet 120A and a backside sheet 120B layered on each other with a hollow part interposed therebetween. The backside sheet 120B is recessed toward the hollow part to provide a plurality of first recesses 200S and a plurality of second recesses 200L. The front-side sheet 120A and the backside sheet 120B are connected to each other with plural ribs by welding bottoms of the first recesses 200S and the second recesses 200L to the front-side sheet 120A. The resin-laminated board has a thin-plate part 100a having the first recesses 200S with small depth and a thick-plate part 100b having the second recesses 200L with large depth, and the first recesses 200S and the second recesses 200L are arranged at substantially the same pitch.

A molding method for a resin molded article includes: a step of sandwiching a sheet-shaped resin in a molten state extruded downward by a pair of rollers, and sending out downward the sheet-shaped resin in the molten state by a rotational driving of the rollers so as to allow a first stretching; a step of drawing downward the sheet-shaped resin in the molten state sent out downward so as to allow a second stretching; a step of disposing the sheet-shaped resin in the molten state that is drawn in a side portion of a mold disposed below the pair of rollers; and a step of molding the sheet-shaped resin into a shape conforming to a mold shape by depressurizing a sealed space formed between the sheet-shaped resin in the molten state and the mold and/or pressurizing the sheet-shaped resin toward the mold.

Provided is a resin panel without warpage, in which weight reduction and high rigidity of the resin panel have been promoted. The resin panel (1) according to an aspect of the present invention is a resin panel (1) having a back wall (3), a front wall (2) facing the back wall (3) with a gap therebetween, and ribs (3a) formed by having portions of the back wall (3) depressed toward the front wall (2) and welded to the inner surface of the front wall (2), characterized in that the back wall (3), the front wall (2) and the ribs (3a) are configured by mold-clamping, in a split mold, a first molten resin in a molten state and incorporating a plate-shaped filler, which constitutes the back wall (3), and a second molten resin in a molten state and incorporating a plate-shaped filler, which constitutes the front wall (2), the first molten resin and the second molten resin having been extruded and flowed out from an extrusion apparatus, and the longitudinal direction (3a1) of the ribs (3a) is non-parallel to the direction of flow of the first molten resin and the second molten resin.
