In various aspects, the present disclosure pertains to thermoformable, multi-layer polymer films comprising a core layer that is comprised of a blend of high density polyethylene and low density polyethylene and, at least one outermost layer that is comprised of a blend of a cyclic olefin copolymer, polyethylene, a functionalized polymer, a dispersing agent and a mineral filler. The present disclosure includes thermoformed webs made from such films, the webs having one or more thermoformed cavities contained therein. Other aspects of the disclosure pertain to methods of forming such thermoformed webs, packaged products comprising such thermoformed webs, and methods of recycling such thermoformed webs.

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.

A protective film 10 of the present invention includes a base material layer and a pressure sensitive adhesive layer, and is used by being attached to a resin substrate 21 at the time of performing heat bending on the resin substrate 21. The pressure sensitive adhesive layer contains a polyolefin having a melting point of lower than 125° C. The base material layer has a first layer which contains a polyolefin having a melting point of 150° C. or higher, and a second layer which contains an adhesive resin. In a case of heating the protective film 100 having such a configuration, in a state of being interposed between two attaching substrates which are formed of polycarbonate, at 145° C. for 30 minutes, peeling off one attaching substrate on the side of the pressure sensitive adhesive layer at 25° C., and then viewing a surface of the one attaching substrate in a plan view, a residual ratio of an area where the pressure sensitive adhesive layer remains is 5% or less.

The invention relates to a seat for a vehicle, preferably for a land craft, a watercraft, and/or an aircraft, comprising at least one multilayer structural component (1) with at least one first (6) and at least one second ply (5) of a composite material, in each case containing fibers which are integrated into a thermoplastic, and with a layer (7) which is arranged between said plies and is made of at least one foamed thermoplastic; to a method for producing same, said method having at least the following steps (A): providing at least one first and at least one second ply of a composite material, in each case containing fibers which are integrated into a thermoplastic, (B) thermoforming the first ply of composite material into a lower seat shell, (C) thermoforming the second ply of composite material into an upper seat shell, (D) arranging the lower seat shell and the upper seat shell in a tool, such that a gap is formed between the two seat shells, (E) introducing foamed particles made of a thermoplastic into the gap, and (F) pressing the two seats shells and the foamed particles in order to obtain the seat; and to the use of the seat in a vehicle, preferably in a land craft, a watercraft, and/or an aircraft.

A method of fabricating a decorated molding article includes forming an all-in-one coating on a substrate and performing a curing step, thereby forming a composite layer structure with a protective effect, a color effect, and a bonding effect. The composite layer structure may form a molded film with better physical properties (e.g., higher hardness, better protection effect, and the like) after the blister molding process. Therefore, the molded film of the embodiments may be applied to a laser engraving process to form a variety of light-transmitting decorated molding articles.
