Title: The production of films of predetermined shape
IPC: B65D65/46
Filed: 1953-02-16
Abstract: Self-supporting films of predetermined complex shape are produced from a solution of a cellulose ether in water or aqueous caustic alkali, the ether having a viscosity in 2 per cent by weight solution at 20 DEG  C. of at least 100 cp. and the solution having a concentration not exceeding 10 per cent and a flocculation temperature below its boiling-point, by raising the temperature of the surface of a former of the required shape to above the flocculation temperature, contacting the surface with the solution as by spraying or immersion, thereby to produce a gelatinous layer of the ether on the surface of the former, drying the gelatinous layer on the former while maintaining its temperature above the flocculation temperature at least until the film has been rendered self-sustaining, and removing the film so produced from the former. The cellulose ether may contain methyl or ethyl groups either alone or together with other alkyl groups, as in methyl or ethyl hydroxyethyl cellulose or methyl or ethyl carboxymethyl cellulose. The surface temperature of the former should generally be about 80-100 DEG  C. and that of the cellulose ether solution should be room temperature or below.  The former may be precoated with mineral oil or a silicone grease or metallized to facilitate removal of the film, or the former may be hollow and made of deformable material such as rubber, in which case the former may be expanded by the introduction of air or water under pressure prior to the formation of the film and subsequently contracted by reducing the pressure, whereby the film is loosened.  The thickness of the film is preferably 5-50 microns, and the concentration of the cellulose ether solution may be 1-5 per cent.  A plasticizer such as glycerol or a polyglycol may be added to the solution.  In the example a test tube is filled with boiling water and immersed for 5 seconds in a 2 per cent solution in water of ethyl hydroxyethyl cellulose having a degree of substitution by ethoxyl and hydroxyethyl of 1.3 and 0.7 respectively.  The tube with an adherent layer of gel is then removed from the solution and the gel is immediately dried by slowly rotating the tube while it is exposed to the rays of an infra-red lamp until substantially all the water has evaporated from the gel, leaving a transparent film which is then removed from the tube.  Specification 643,853 is referred to.
