The invention relates to a sheetlike composite comprising, as mutually superposed layers in a direction from an outer face of the sheetlike composite to an inner face of the sheetlike composite, a) a carrier layer, b) a first adhesion promoter layer having a first acrylate content, c) a barrier layer, d) a further adhesion promoter layer having a further acrylate content, and e) an inner polymer layer; wherein the first acrylate content and the further acrylate content are each in a range from 7% to 40% by weight, based on the weight of the respective adhesion promoter layer. The invention further relates to methods of producing a sheetlike composite, a container precursor and a closed container and to the aforementioned method products; to a container precursor and a closed container each including at least one sheetlike region of the sheetlike composite; to uses of the sheetlike composite for production of a food or drink product container and in a microwave oven; and to a use of an adhesion promoter composition A and of an adhesion promoter composition B for production of a sheetlike composite for a food or drink product container.

A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.

There is provided a co-injection molded multilayer structure comprising a barrier layer and outer layers laminated to contact with the barrier layer on its both sides, wherein the barrier layer is made of a resin composition (X) comprising an ethylene-vinyl alcohol copolymer (A) and an alkali metal salt (B) of a higher fatty acid, having a melting point of 250 C. or lower; the ethylene-vinyl alcohol copolymer (A) has an ethylene unit content of 20 to 60 mol % and a saponification degree of 90% or more, and a content of the alkali metal salt (B) in the barrier layer is 50 to 1500 ppm in terms of metal atoms; and the outer layers are made of a resin composition (Y) comprising an unmodified high-density polyethylene (F) and a maleic anhydride-modified polyethylene (G), and a maleic anhydride modification rate relative to the whole resin composition (Y) is 0.005 to 0.1 wt %. This co-injection molded multilayer structure has excellent adhesiveness, so that its oxygen barrier performance can be maintained even after being subjected to an impact due to falling or the like.

A flexible package made with a multilayer polyethylene film and an integral fitment; and a process to prepare the flexible package are disclosed. The amount of polyethylene used to prepare the package is at least 90 weight % of the total weight of polymer used to prepare the package, which allows the package to be recycled. The fitment is made from a linear low density polyethylene which facilitates the manufacture of the package.

An oxygen absorptive film 10a of the present invention is an oxygen absorptive film provided with an oxygen absorption layer 2 and a skin layer 4 laminated on at least one surface of the oxygen absorption layer, wherein the oxygen absorption layer contains polyolefin and cerium oxide having oxygen deficiency, and wherein the skin layer contains an acyclic olefin-based polymer and a cyclic olefin-based polymer.

An article is described including an article surface and a coating set comprising an optional tie coating or layer, a barrier coating or layer, and a pH protective layer. The respective coatings or layers can be applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. Examples of such an article are a thermoplastic syringe, vial, or blood collection tube with a coated interior portion containing a pharmaceutical preparation or other fluid with a pH of 4 to 8, alternatively 5 to 9. The barrier coating or layer prevents oxygen from penetrating into the thermoplastic syringe, vial, or blood collection tube. The tie coating or layer, if present, and the pH protective coating or layer protect the barrier layer from the contents of the syringe, vial, or blood collection tube.

A battery packaging material including a laminate that is provided with a barrier layer, a heat-fusible resin layer positioned on one surface side of the barrier layer, and a polyester film positioned on the other surface side of the barrier layer. When the infrared absorption spectrum on the surface of the polyester film in 18 directions at intervals of 10 from 0 to 180 is obtained using the total reflection method of Fourier transform infrared spectroscopy, the ratio (surface orientation degree, Y.sub.max/Y.sub.min) of the maximum value Y.sub.max and the minimum value Y.sub.min of the ratio (Y.sub.1340/Y.sub.1410) of the absorption peak intensity Y.sub.1340 in 1340 cm.sup.1 and the absorption peak intensity Y.sub.1410 in 1410 cm.sup.1 in the infrared absorption spectrum is in the range of 1.4-2.7.

A bag having a front panel and a back panel coupled together through a plurality of seals, defining a cavity structurally configured to retain a flowable material. The panels are formed from a film that has a first film portion and a second film portion laminated together at an interface. The first film portion has an inner surface and an outer surface and includes an oriented polyethylene. The second film portion is a coextrusion having an inner surface and an outer surface. The extrusion has a core, with a first overlying layer on one side of the core and a second overlying layer on a second side of the core opposite the one side. The core includes EVOH. The first overlying layer and the second overlying layer include polyethylene.
