The invention further provides novel polyimide film having improved adhesive property.A method for improving adhesive property of polyimide film according to the present invention comprises a combination of steps of;execution of a liquid applying process for treating polyimide film surface by exerting physical mechanical force on said film surface under the condition of that said film surface remains wet with water or organic solvent, or solution of organic solvent or aqueous solution; and execution of a surface treatment process for treating polyimide film surface by performing selected treatment among flame treatment, alkaline treatment, coupling agent treatment or surface treatment by way of projecting grinding material of fine grading onto film surface at high velocity, and said steps are performed in an arbitrary order. For example, using a surface treating device 10 shown in FIG. 1, consecutive execution of a surface treatment process for treating film surface, a liquid applying process and a drying process is realized by that polyimide film 22 is run from a feeding device 18 to a winding device 20.

    Abstract: Methods for providing a low permeability coating on the interior of a refillable plastic container, such as a PET beverage bottle, include coating of a liquid crystal polymer (LCP) by depositing LCP monomers on the interior surface of the container and bi-axially orienting the monomers continuously while reacting the monomers to produce the polymer. The interior surface of the container may be pre-treated to produce free radicals which enhance the attachment of the monomers to the surface. Also, the surface may be post-treated to eliminate unsaturated radicals or free monomers. The application of the monomers to the interior surface of the container can be effected by condensing a gas blend of monomers, by spraying liquid monomers or by filling with liquid monomers and then emptying to leave a residual coating. The monomers are reacted by preheating them or by subjecting them to a heated inert gas. To achieve the bi-axial orientation of the monomers, the interiorly coated container may be alternately subjected to longitudinal and circumferential magnetic fields while supported for incremental end-to-end rotation and rotation about its axis. Another technique for achieving the bi-axial orientation comprises subjecting the container to alternately applied longitudinal and circumferential electrostatic fields.

    Abstract: A method for coating a cylindrical container with a thin, resinous coating by spraying powdered resin is disclosed. The technique involves spraying of finely divided resin particles into a beverage container from spray nozzles external to the container. The container may be sprayed by directing a pulse of a predetermined quantum of resin into the container to deposit a substantially uniform coating. Alternatively, a continuous flow of resin at a predetermined rate may be sprayed into a container. The resin particles are caused to adhere to the container by preheating the container. The coating is rendered continuous by preheating the container to temperatures above the softening point of the resin. Postheating of the coated container at temperatures in excess of about 300.degree. F. matures the coating.

    Abstract: The interior of cylindrical metal containers are coated with a thin, substantially uniform comestible coating by spraying finely divided resinous particles into the container after it has been preheated by a plasma arc-generated flame to a temperature above the softening point of the resin. The process is capable of coating containers at rates up to about 600 containers per minute with a substantially pore-free film having a thickness less than about one mil to as low as 0.1 mil and lower. Typical of containers coated by the process are conventional two-piece aluminum containers. Typical preheat temperatures are from about 150.degree. F. to about 525.degree. F. for aluminum containers and from about 150.degree. F. to about 1000.degree. F. for steel containers. A typical preheat time is from about 30 to about 300 milliseconds. Typical resins are finely divided thermosetting epoxy powders. The plasma arc device may also be used to post-heat coated containers to mature the coating.
