Abstract: A closure system including a cap and a spout, where the cap and/or spout contain at least one discrete layer of barrier material. In one example, the spout includes a conduit and a seal member, the conduit being arranged about an imaginary axis and the seal member having one or more surfaces configured to be secured to a container. The cap includes an inner circumferential surface, the inner circumferential surface arranged to encompass the conduit. The cap also includes a first discrete layer of thermoplastic resin and a first discrete layer of barrier material and the seal member includes a second discrete layer of thermoplastic resin and a second discrete layer of barrier material.

Abstract: A container including a tray and a lidding film is provided. The lidding film is removably coupled to the tray and includes a breakable layer, a lidding layer coupled to the breakable layer, and a PSA layer. A reseal portion of the breakable layer is sealed to a flange of the tray. The PSA layer is arranged between the lidding layer and the breakable layer. The PSA layer includes a reseal portion to adhere to the reseal portion of the breakable layer. The reseal portion of the breakable layer separates from an inner portion when the container is initially opened such that the reseal portion of the breakable layer remains sealed to the flange and the inner portion of the breakable layer remains coupled to the lidding layer. The container is resealed by adhering the reseal portion of the PSA layer to the reseal portion of the breakable layer.

Abstract: An oriented film having a combination of polyolefin and polyamide layers. The film is low shrink and can be monoaxially or biaxially oriented. The polyolefin layer is positioned between two polyamide layers. A tie resin layer may be included between the polyolefin layer and either or both of the polyamide layers. A barrier layer, such as one formed from ethylene vinyl alcohol, may be positioned inside of the polyamide layers. The polyolefin layer may additionally incorporate a polyamide. The overall composition of the oriented film is selected so that the polyamide content is minimized enough that the film may be recycled in current polyethylene recycling streams.

Abstract: The present disclosure provides semirigid pouch designs and methods of manufacturing pouches. Such pouches can be made of plastic or non-plastic materials and may be easily sorted and recycled within existing rigid packaging recycling streams. The pouches are semirigid, while flexible, and will substantially retain their shape during and following product dispensing. This is accomplished by sealing a lower edge of a wall of semirigid plastic or non-plastic materials to a rigid or semirigid base, enabling the pouch to stand up on the base. Portions of an upper edge of the wall are affixed together to form a space to hold the foodstuffs. Further, the present pouch design does not require an additional label to be applied by the manufacturer, as the present design provides a large, uninterrupted, surface area for printing of advertisements and/or labels directly to the outer surface of the pouch.

Abstract: A spill-resistant spout and method of injection molding a spill-resistant spout. The spill-resistant spout includes a conduit portion having an exit aperture in fluid communication with a central channel; and a seal portion having a bottom surface, the seal portion secured to the conduit portion and in fluid communication with the central channel, the bottom surface comprising at least two intake apertures configured to receive foodstuffs from a container. The use of multiple intake apertures increases the surface tension on the foodstuffs attempting to pass through the intake apertures while maintaining or increasing the total flow volume of foodstuffs through the spill-resistant spout. Additionally, the barrier qualities of the spill-resistant spout can be enhanced by providing one or more discrete layers of thermoplastic material and one or more layers of barrier material within at least one portion of the spill-resistant spout.

Abstract: Described herein are high stiffness, snappable food contact material compositions containing at least one polypropylene, a hydrocarbon resin, and optionally one or more other additives. The disclosed compositions exhibit a combination of mechanical, chemical, and/or optical properties that enable wider use of such polypropylene-based compositions in food packaging applications, including in Form-Fill-Seal food packaging where high stiffness, snappability, thin walls, and good clarity are important factors. Also described herein are articles comprising the disclosed compositions and methods of manufacturing such articles.

Abstract: Described herein are high stiffness, high impact strength and clarified polypropylene-containing compositions. The disclosed compositions comprise a polypropylene, a nucleating agent, and optionally one or more additives. In certain aspects, the polypropylene includes a first polypropylene and a second polypropylene that is different from the first. The disclosed compositions exhibit high stiffness, high impact strength, improved clarity, and improved thermoformability. Also described herein are articles comprising the disclosed compositions and methods of manufacturing such articles.

Abstract: A container and method of manufacture of a container made of a single material is provided. The container includes a base having a base perimeter with a surface, and a wall having an upper edge and a lower edge, the upper edge comprising two upper edge portions, wherein the lower edge is affixed about the entire perimeter surface, and the first upper edge portion is affixed to the second upper edge portion, thereby forming a space to hold foodstuffs. The base stock material is cut and formed into a base with the base perimeter. A seal is applied between the lower edge of the wall and the surface of the base perimeter. Another seal is applied to two vertical end portions of the wall, forming a cup-like container with an internal space. A final seal is applied between two portions of the upper edge of the wall completing the container.
