A container formed of a common one-piece multilayer thermoplastic substrate. The container wall has an outer layer and an adjacent underlying layer. And the underlying layer has a colorant visible through the outer layer. The colorant in the underlying layer can be one or more pigments and or one or more dyes.

A multi-layer article for storing a product, such as a pharmaceutical product, includes a first layer that includes a polychlorotrifluoroethylene and/or copolymer of polychlorotrifluoroethylene and vinylidene fluoride. The article also includes a tie layer disposed on the first layer. The tie layer includes an ethylene acrylate resin. The article further includes a second layer that is disposed on the tie layer. The second layer includes a polyester, polycarbonate, polypropylene, polyethylene, or combinations thereof. The article further optionally includes two optional layers each independently including a polychlorotrifluoroethylene and/or copolymer of polychlorotrifluoroethylene and vinylidene fluoride, or an ethylene acrylate resin, or a polyester, polycarbonate, polypropylene, polyethylene, or combinations thereof. The article has a clarity of at least about 90% as determined using ASTM D1003-13.

A delamination container includes an engaging protrusion that is provided in an area extending over at least a ground contact portion and a recess and protrudes from either one of an outer layer body and an inner layer body and engages with the other in an undercutting manner. Further, a preform includes an engaging protrusion that is provided in an area extending from at least a boundary between a bottom and a trunk to just before an axial center of the bottom and protrudes from either one of an outer body and an inner body and engages with the other in an undercutting manner.

An article with a hollow body defined by a wall with an inner surface and an outer surface. The wall is comprised of 2 or more layers including a first skin layer with effect pigments and an opaque core. In some examples, the effect pigment can be a special effect pigment adapted to produce at least one interference color.

An object of the present invention is to provide a polyolefin composition prepared by kneading a hygroscopic inorganic filler into a polyolefin, without substantially using an additive such as a dispersant or an antioxidant, the polyolefin composition having good dispersibility of the hygroscopic inorganic filler as well as excellent moldability. By kneading anhydrous magnesium sulfate as a hygroscopic inorganic filler into a polyolefin, without substantially adding an additive such as a dispersant or an antioxidant, and by setting the moisture content in the kneaded product to 0.1 wt % or less, a polyolefin composition having good dispersibility of anhydrous magnesium sulfate as well as excellent moldability can be obtained.

The invention describes the use of magnetic platelet particles as a multifunctional additive to various formulations of polyolefin plastic films usable to fabricate packaging and to provide said packaging with similar barrier properties as aluminium metallizations or other gas barriers, with the added benefit of allowing separation and recovery of the packaging by magnetic means. Such novel additives, films and packaging are environmentally friendly and food-safe, so that after use they can be either recovered for reuse, composted, or dumped in the environment to biodegrade. The invention comprises various types of films comprising the additive and methods to improve the properties of said films.

Disclosed herein are polymeric products, along with masterbatches and methods of making polymeric films, sheets, and extruded articles from the masterbatches, in which the films and polymeric products exhibit layer-like morphology and retain good barrier properties to a permeant of interest. The masterbatches include one or more structural and barrier polymers and a compatibilizer.

A multilayered structure having a liquid layer (5) on a surface of a plastic underlying layer (3), wherein a liquid diffusion prevention layer (1) is provided on the lower side of the underlying layer (3) to suppress or block a diffusion of a liquid that forms the liquid layer (5), and a covering ratio F of the liquid layer (5) is maintained to be not less than 0.5. With this structure, the surface properties of the liquid layer (5) can be stably maintained over long periods of time.

Molded multilayer polymer compositions and structures are provided, including a body portion having a body wall. The body wall has a first layer comprising a copolymer HDPE, a second layer comprising a homopolymer HDPE, and a third layer comprising a mix of the copolymer HDPE of the first layer and the homopolymer HDPE of the second layer, wherein the third layer is disposed between the first layer and the second layer, and a total weight content of the homopolymer HDPE is at least about 30 wt-% of the body wall. The body wall has an overall wall thickness T, the first thickness is about 10% of the overall wall thickness T, the second thickness is about 20% of the overall wall thickness T, and the third layer has a third thickness of about 70% of the overall wall thickness T.

A container includes an outer layer defining an exterior surface and including poly (ethylene terephthalate) and an inner barrier layer including semi-crystalline poly(ethylene furanoate) including semi-crystalline poly(ethylene furanoate) where the poly(ethylene furanoate) has a crystallinity X.sub.c of 3 to 40%.
