Co-processable multi-layer laminates having a high T layer and at least one low T layer with layers having properties of high strength, lo- or no-haze, and transparency after processing into various multi-layer forms are useful for packaging and container applications. The multi-layer laminate has at least one low T layer of a first thermoplastic polyester having at least one crystallization rate inhibitor. The total amount of crystallization rate inhibitor is effective to prevent substantial haze in the low T layer upon heating. In most applications, the total amount of crystallization rate inhibitor also does not substantially inhibit strain-induced crystallization of the at least one low T layer when the laminate is stretched during processing. The multi-layer laminates of the invention have improved properties such as reduced shrinkage and/or high barrier properties, with a very small amount of high T material used to impart these improved properties to the laminate.

Doorway or passageway arches and a mold and method for making doorway arches, wherein the arches comprise pre-fabricated plaster, two sides that are substantially perpendicular to each other, a concave arcuate side extending between the sides and flanges extending outward from each side for securing the arch to adjoining walls defining a comer, and the mold comprises a base, at least two perpendicularly disposed slots, at least one slidably insertable and removable board for each slot, a mold projecting upward from said base and having a convex side extending between opposing ends of said boards, flanges disposable along the boards and a volume for receiving a hardening agent, such as plaster.

A process for treating a liquid crystal polymer film which includes the steps of: heating a film obtained by extrusion molding of a liquid crystal polymer, while contacting at least one surface of the film with a supporting body, to melt the polymer; cooling the melted polymer to form a solidified polymer layer; and separating the solidified polymer layer from the supporting body. The process readily provides liquid crystal polymer films having excellent resistance to intra-layer delamination and high tensile strength and elongation, as well as excellent resistance to abrasion, dimensional stability when heated, and resistance to folding.
