The present invention discloses multilayer blown films for shrink label and related applications. These multilayer blown films can comprise a core layer containing an ethylene polymer, and inner and outer layers containing conjugated diene monovinylarene block copolymers.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

A method for beautifying a balsa wood model aircraft with a thermal shrink covering film, so that the balsa wood model aircraft with a thermal shrink covering film is obtained. This method makes a model aircraft colorful, reduces labor costs, improves the beautifying and painting effect of the model aircraft, and also improves the pneumatic performance of the model aircraft.

A polyethylene-based polymer composition suitable for use in a shrink film, the polyethylene-based polymer composition comprising a low density polyethylene having a density of from 0.917 g/cc to 0.935 g/cc and melt index, I.sub.2, of from 0.1 g/10 min to 5 g/10 min, a linear low density polyethylene having a density of from 0.900 g/cc to 0.965 g/cc and melt index, I.sub.2, of from 0.05 g/10 min to 15 g/10 min, or combinations thereof, a material that absorbs radiation in the near-infrared, visible, and ultraviolet spectral wavelength ranges, and optionally, a medium density polyethylene, a high density polyethylene, or combinations thereof.

An expander tool (1) includes a tool head (2) which includes expanding means (3) insertable inside the end of the pipe (P), and which includes a plurality of spreading elements (4) that are radially movable in relation to a center longitudinal axis (x) of the tool head (2) between a starting position (I) and an outwardly extended expansion position (II), and that have an outer spreading surface (5) configured to press against an interior surface of the end of the pipe (P). Expander tool (1) includes a piston (6) to spread spreading elements (4) by moving along the axis (x) from a retracted piston position (III) to a fully extended piston position (IV) against interior surfaces of the spreading elements (4), and an actuator (7) for moving piston (6). Outer spreading surfaces (5) include a circumferential groove (8) that leaves an undamaged smooth and intact surface to the inner surface.

Disclosed is a method for making a flexible container. The method implements an injection mold having a collapsible core that expands/moves to define the apertures and, in some embodiments, holds a flexible film in place during the injection mold process and collapses/moves back post-injection molding to allow for the flexible container to be readily removed from the die. In addition, the method described includes a post-injection molding anneal process that is implemented to allow the flexible film to shrink so as to provide for form-fitting of the film to the molded portion of the container.

To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

The present disclosure relates to crystallizable shrinkable films and thermoformable sheets comprising amorphous polyester compositions which comprise residues of terephthalic acid, neopentyl glycol (NRG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and diethylene glycol (DEG), in certain compositional ranges having certain advantages and improved properties including recyclability.

The present disclosure relates to crystallizable shrinkable films and thermoformable film(s) or sheet(s) comprising blends of polyester compositions which comprise residues of terephthalic acid, neopentyl glycol (NRG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and diethylene glycol (DEG), in certain compositional ranges having certain advantages and improved properties.

There is provided a method of making a curved barrier film, including: depositing a barrier layer between a first organic layer and a second organic layer to form a barrier film; and thermoforming or vacuum-forming the barrier film from a flat barrier film to a curved barrier film; wherein the barrier film includes the barrier layer having two opposing major surfaces, wherein the barrier layer includes buckling deformations and non-buckling regions; the first organic layer in direct contact with one of the opposing major surfaces of the barrier layer; and the second organic layer in direct contact with the other of the opposing major surfaces of the barrier layer.
