摘要： A laminated polypropylene-based film suitable for retort packaging having an exterior film, a barrier layer, and a sealing layer. The retort packaging film has a total composition including high levels of polyolefin-based polymers and polypropylene-based polymers such that the material can be processed efficiently in a polypropylene recycling process. Advantageously, the film retains the properties required to suitably withstand the retort process and produce a high-quality shelf-stable packaged product.

摘要： A formed article includes a rigid film, a liner film, and a cavity. The rigid film includes a thickness and a line of weakness. The rigid film and the liner film are joined to each other. Further, the line of weakness is positioned in the cavity. The formed article is configured to facilitate separation (e.g., peeling) of the rigid film from the liner film.

摘要： The film structure has a first exterior layer having a high-density polyethylene and an inorganic particle, a second exterior layer having a polyethylene-based material for sealing, and an interior layer having a high-density polyethylene, a nucleating agent and a hydrocarbon resin. The film may be use as a heat-sealable lid component for packaging and offers high moisture barrier, good heat resistance, and push-through and/or child-resistance performance while maintaining an overall composition acceptable for recycling.

摘要： A process for producing an adhesive-free laminate is described herein. The process includes printing an ink on a surface of a first film, exposure of the printed film to UV radiation such that the ink is at least partially cured, contacting the first film to a second film such that the ink is between the first and second film, and exposing the combination of the first film, the ink and the second film to a second UV radiation. It has been found that this process can produce a high-quality laminate, without the presence of an adhesive.

摘要： This disclosure concerns a barrier packaging film including a polyolefin substrate layer having a thickness in the range of from 10 μm to 100 μm, an inorganic coating layer, and a polymeric buffer layer positioned between the polyolefin substrate and the inorganic coating layer, the polymeric buffer layer in direct contact with the inorganic coating layer, wherein the inorganic coating layer comprises a wave structure characterized by an average amplitude in the range of from 0.25 μm to 1.0 μm and a wavelength in the range of from 2 μm to 5 μm. Also disclosed are packages (e.g., hermetically sealed packages) formed from the barrier packaging film.

摘要： A foldable blank is disclosed. The foldable blank includes a base, a first sidewall, a first flange, and a restraining feature. The first sidewall is connected to the base. The first flange is connected to the first sidewall. The restraining feature is located in at least one of the base and the first sidewall. Each of the base, the first sidewall and the first flange are constructed from a polymeric sheet. The restraining feature is a permanent imprint in the foldable blank. The foldable blank is generally planar with the exception of the restraining feature. The foldable blank may be erected to a folded tray. The folded tray may be connected with a lid to form a package. The package may be suitable for non-hermetic applications.
