The present invention provides a container used in a stereolithography apparatus and having excellent transparency, shape accuracy, and durability. The present invention relates to a container for holding a photocurable composition (3), the container being used in a stereolithography apparatus comprising a container (2), an active energy beam irradiation apparatus (5), and an actuator (8), wherein the container (2) comprises a bottom (2′) and a wall, the bottom (2′) comprises a first layer (X) comprising a hard resin, a second layer (Y) comprising a soft resin, and a third layer (Z) comprising a fluorine resin, the second layer (Y) is laminated on the first layer (X) and the third layer (Z) is laminated on the second layer (Y), the pencil hardness measured according to JIS K 5600-5-4:1999 for the first layer (X) is 3 B or harder, the hardness measured for the second layer (Y) using a type A durometer compliant with JIS K 6253-3:2012 is 10 to 90, and the third layer (Z) has a thickness of 0.1 to 5.0 mm.

A delaminated container has a main body portion and an opening portion. An accommodation space of the delaminated container is formed by a body inner surface of the main body portion and an opening inner surface of the opening portion. The delaminated container includes a first layer and a second layer. The first layer includes a first tightly-attached section. At the main body portion, the first layer is located closer to the body inner surface than the second layer located thereto and is exposed on the body inner surface. The second layer includes a second tightly-attached section. The first tightly-attached section and the second tightly-attached section are tightly attached to each other. The first tightly-attached section and the second tightly-attached section are both located at the opening portion of the delaminated container.

Provided is a multilayer container including a polyester layer containing a polyester resin (X), and a polyamide layer containing a polyamide resin (Y), a yellowing inhibitor (A), and an oxidation accelerator (B). The content of the polyamide resin (Y) is from 0.05 to 7.0 mass% relative to the total amount of all polyamide layers and all polyester layers. The yellowing inhibitor (A) is a dye, and the content of the yellowing inhibitor (A) is from 1 to 30 ppm relative to the total amount of all polyamide layers and all polyester layers.

The present invention relates to a sustainable article for packaging which could be made substantially free of virgin petroleum-based compounds; in particular it relates to new packaging made from coloured post-consumer resin (PCR) having a high NIR absorption. A need remains to create a circular economy for coloured and/or black plastic by bringing the waste coloured and black plastic into new packaging while using Near infrared (NIR) detectable pigment in the colourant masterbatch. It is therefore an object of the present invention to bring the coloured or black plastic waste into new packaging. It has be found that a sustainable packaging in consumer acceptable black using NIR detectable pigment can be obtained by using a multilayer post-consumer resin, comprising a thinner outer layer of post-consumer resin of natural plastic waste (N-PCR); and a thicker inner layer comprising at least 50% coloured plastic waste (J-PCR).

Polyolefin resin modifiers are provided that contain a nonionic surfactant, an organic sulfonate salt, and an inorganic salt. The organic sulfonate salt can be at least one selected from the group consisting of alkylsulfonic acid alkali metal salts whose alkyl group has 6 to 22 carbon atoms, alkylarylsulfonic acid alkali metal salts whose alkyl group has 6 to 22 carbon atoms, and sulfonic aliphatic ester alkali metal salts whose alkyl group has 6 to 22 carbon atoms. The inorganic salt can be at least one selected from the group consisting of sodium sulfate, potassium sulfate, calcium sulfate, lithium sulfate, sodium chloride, potassium chloride, lithium chloride, magnesium chloride, and calcium chloride.

[Problem to be Solved] To prevent delamination of a film layer in a sheet material container in which an enclosing portion is formed in an interlayer between a first film layer and a second film layer.

[Solution] A sheet material container includes a container body 6, and an inner container 7 that is covered by the container body 6 and defines an accommodation space, wherein the container body 6 is formed of a sheet material 3 including a first film layer 1 and a second film layer 2 disposed inside the first film layer 1, the sheet material 3 has a joint portion 32 at which an interlayer between the first film layer 1 and the second film layer 2 is joined and an enclosing portion 51 in which a filler can be enclosed in the interlayer between the first film layer 1 and the second film layer 2, and the first film layer 1 has an extruded multilayer structural part having a polyolefin resin layer 11/an ethylene-vinyl alcohol copolymer resin layer 12 on a side facing the enclosing portion 51.

A multi-layer product as a seal includes a cover layer having an adhesive layer and a backing layer with a release layer. The cover layer has a first part including one or more releasable portions, each having an associated patch. The backing layer has a pre-formed line of separation that extends across the seal from the first edge to the second edge and separates the backing layer into a first part and a second part. The second part of the backing layer includes at least one removable portion at an edge thereof. Each removable portion is defined by one or more pre-formed lines of separation. The cover layer has a second part including at least one flap portion each of which is substantially coincident with a respective one of the removable portions and defined by one or more pre-formed lines of separation in the second part of the cover layer.

A resin composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an olefin polymer; and (C) a sorbic acid ester; wherein the sorbic acid ester (C) is present in an amount of 0.00001 to 10 ppm based on the weight of the resin composition. The resin composition exhibits reduced susceptibility to coloration.

The presently disclosed subject matter is generally directed to packaging film and packages constructed from water-dispersible and/or biodegradable material. The water-dispersible and biodegradable package consists of a first layer of a water-dispersible material constituting an interior of the package, and a second layer of a biodegradable material constituting the exterior of the package. The package may have printed indicium printed onto the exterior of the package.

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.
