Provided are a multilayered article and a multilayered container comprehensively excelling in oxygen barrier properties, delamination resistance, and transparency. The multilayered article includes a layer containing a polyester resin as a main component and a layer containing a polyamide resin as a main component; wherein the polyamide resin included in the layer containing a polyamide resin as a main component includes from 90 to 60 parts by mass of a polyamide resin (B) per 10 to 40 parts by mass of a polyamide resin (A). The polyamide resin (A) is an aliphatic polyamide resin. The polyamide resin (B) includes a structural unit derived from a diamine and a structural unit derived from a dicarboxylic acid, 70 mol % or more of the structural unit derived from a diamine being derived from xylylenediamine, and of the structural unit derived from a dicarboxylic acid, from 30 to 65 mol % being derived from an am-linear aliphatic dicarboxylic acid having from 4 to 20 carbons, and from 70 to 35 mol % being derived from isophthalic acid, a total of which does not exceed 100 mol %.

Provided is a PET bottle preform in which delamination is suppressed and a method for the production of the preform. An anchor layer containing a polyester-based urethane resin is formed on an outer surface of the preform.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

A double container includes: an outer layer body including an outer mouth portion and a barrel portion; an inner layer body including an inner mouth portion and a containing portion; an outside air introduction port for introducing outside air; and a plurality of vertical ribs arranged with spacing in a circumferential direction on an inner surface of the outer layer body or an outer surface of the inner layer body, and each extending over the outer mouth portion to the shoulder portion or extending over the inner mouth portion to the containing portion, wherein at least one of the plurality of vertical ribs faces the outside air introduction port.

A blow molded multilayer article with a hollow body defined by a wall with an inner surface and an outer surface. The outer surface has an axial color gradient and/or a gloss gradient. The wall has multiple layers and at least one layer contains an effect pigment and/or an opacifying pigment.

Process for cutting a water-soluble web in a cross-machine direction. Each cutting cycle contains at least two speeds. A first speed matches that of the speed of the water-soluble web and is also the speed at the point of cutting, and a second speed is faster than the speed of the water-soluble web in the machine direction and is the speed at a point in-between two cutting actions.

A blow molded multilayer article with a hollow body defined by a wall with an inner surface and an outer surface. The outer surface has an axial color gradient and/or a gloss gradient. The wall has multiple layers and at least one layer contains an effect pigment and/or an opacifying pigment.

The present invention relates to an integrally blow-moulded bag-in-container and preform for blow-moulding the bag-in-container. An inner layer and an outer layer are used, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.

The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.
