The invention is directed to a thermoplastic film having a first surface and a second surface. The second surface is spaced apart from the first surface. A plurality of perforations extend through the film from the first surface to the second surface. The perforations form capillaries that extend from the second surface. The capillaries are disposed at an angle from about 5.degree. to about 60.degree. with respect to a plane that is perpendicular to the first surface.

The invention relates to an optical retardation film comprising a layer of an anisotropic polymer material with an optical axis substantially parallel to the plane of the layer. The invention furthermore relates to a process of preparing the optical retardation film, to the use of such an optical retardation film in liquid crystal displays, and to a liquid crystal display device comprising a liquid crystal cell and such an optical retardation film.

The invention provides a sheet material which comprises a non-woven plastics film and bonded thereto without an adhesive, a barrier film; the sheet material is especially useful for the production of ostomy bags.

The present invention provides a wrap film or shrink film formed from a resin composition containing [I] a propylene polymer in an amount of 1 to 99 mass %, and [II] an olefin-based polymer in an amount of 99 to 1 mass %, wherein [I] the propylene polymer satisfies the following requirements of: (1) a meso pentad fraction (mmmm) is 0.2 to 0.6, and (2) a racemic pentad fraction (rrrr) and (1-mmmm) satisfy the following relation: [rrrr/(1-mmmm)].ltoreq.0.1. The wrap film or shrink film exhibits ex...

A film cleaner and method for cleaning motion picture film. The cleaner includes a friction-driven roll, spools of cleaning tape, take-up rolls to draw the tapes from the spools, means for contacting the tapes with the film, and a gearing mechanism connecting the friction-driven roll with the take-up rolls. The film cleaning method includes driving the friction-driven roll with film running through a film delivery and take-up system, contacting the surfaces of the film with the cleaning tapes, a...

A film cartridge designed to carry an endless roll of film having a rotatably-mounted drive member with a central hub portion and a flange portion. The spiral roll portion of the endless film is disposed about the central hub portion and is loosely contained between the flange portion and a support surface perpendicular to the rotational axis of the drive member. The inner end of the spiral roll extends as a single loop upwardly and forwardly through a film guide passageway to the front wall of ...

The invention relates to film-to-film skin packaging of articles in which plastic films are placed above and below articles to be tightly packaged therein, effecting a sealed enclosure, and wherein said films are subjected to heat and suction in a vacuum forming machine causing adherence to each other. The primary purpose of the invention is to yield a tamper proof, sealed and airtight package, capable of retaining a controlled atmosphere therein. This is achieved by providing a perforate area o...

The capacitor according to the invention is wound from at least one film (1) comprising a carrier film (3)--serving as dielectric--with at least one conductor layer (4). It has an internal series circuit. The latter is brought about by the conductor layer (4) applied on the dielectric or the conductor layers being divided into sectors (4.1, 4.2) which are mutually arranged and, if appropriate, connected to one another in such a way that a plurality of series-connected elementary capacitors are f...

A film picker for a film cartridge comprising a flat body having at its end a cartridge fixture adapted to be pressed against an outer surface at an inlet of the film cartridge, and a thin elastic guide plate, extracting plate and film pressing plate extending from the end of the body in an overlapping manner with one another. The guide plate and the extracting plate have a width which is substantially the same as that of the film rewound within the cartridge, are individually movably held relat...

A slide mount has a first portion and a second portion. The first portion includes an interior region, an edge, and a slot extending from the interior region to the edge. A cavity is formed between the first portion and the second portion, and extends to the first edge, with a film segment in the cavity extracted therefrom by a film extraction system. The film extraction system includes a piston for disengaging a latch mechanism from the film segment. An extractor arm enters the slot to engage a...
