Abstract:
A plurality of cartons, preferably fabricated from paper, paperboard and/or corrugated paperboard, and particularly of tray or wrapper-style construction, are provided, having integral lid constructions, and outer overlap panels, operably associated with the at least one top panel, to enable articulation of the carton into a substantially completed structure, without interfering with the subsequent articulation of the at least one top panel to enable loading of the carton subsequent to articulation and affixation of the outer overlap panels.
Abstract:
This invention relates to engraved boards that are suitable for use in displays and exhibits including all types of signage, frames and artistic representations. The board is composed of at least two layers. One layer is made essentially entirely of, or includes, high impact polystyrene foam. The other layer can be made of, or include, any thermoplastic polymer.
Abstract:
An improved method of manufacturing blown polyolefin films with increased bubble stability and higher blown film production rates is disclosed. A method in which the amounts and ratios of known antioxidant polymer film additives (phosphites and phenolics) are controlled to provide limited long chain branching (LCB) and greater rheological breadth in a polyethylene melt to improve both processing characteristics and mechanical properties in the resulting film.
Abstract:
A method of modifying a polyethylene material is accomplished by providing a polyethylene resin. The initial rheological breadth of the polyethylene resin is determined. The resin is then modified to adjust the rheological breadth of the polyethylene from the initial rheological breadth to a different rheological breadth that corresponds to a desired resin property, such as haze. A method for predicting clarity and rheological breadth properties is also provided, which utilizes a template of measured properties for polyethylene resins.
