Abstract: This present invention discloses a polymer/potassium permanganate composite film obtainable by a process comprising the steps of using silane coupling agent for surface treatment of potassium permanganate, mixing 0.15-0.75 g of modified potassium permanganate with 10-20 g of polymers together to obtain a mixture, and coating the mixture to obtain a composite film. The composite film can absorb ethylene generated by fruit, thus extending fruit ripening time, keeping fruit fresh. It can be widely used as food packaging materials. The composite film also has a good oxygen barrier property and has a good efficiency to remove bacteria. Therefore it can be widely used in the pharmaceutical industry. The preparation method is scientifically sound, simple, and has high level of operability, thus making it possible for batch preparation.

Abstract: In manufacture of a polyimide film, self-supporting film is heated with both ends in a width direction held and carried by the tenter apparatus. The tenter apparatus has a guide member placed on each side of a carry path for the self-supporting film and a pair of tenter chains each moved along the guide member and each including a film holding mechanism for holding an edge portion of the self-supporting film. The tenter chain has a rotating body supported rotatably around a shaft member extending in a direction in parallel with a carry face of the self-supporting film and perpendicular to a longitudinal direction of the guide member for movably supporting the tenter chain. The shaft member is directly or indirectly fixed to a member identical to a member to which the film holding mechanism is fixed.
