PURPOSE:To obtain a film having high transparency and capable of excellently carrying out processing such as printing, coating, laminating, etc., consisting of a thermoplastic resin containing a low molecular liquid crystal forming compound, expressing excellent gas barrier and highly suitable for packing of foods and medicals preserved for a long period of time. CONSTITUTION:A film consisting of a thermoplastic resin containing a low molecular liquid crystal forming compound. The thermoplastic resin can be a polyester. A content of the low molecular liquid crystal forming compound is 0.1-50wt.% of the resin. Polyethylene terephthalate is specifically preferable as the polyester resin. N-(4-cyanobenzylidene)-4-actiroxyaniline, etc., are used as the liquid crystal forming compound. The film is 0.2-1000mum thick and light permeability is preferably >=80%. The liquid forming compound is preferably molten and needed with the resin, pelletized and, then, fed to an extruder. |
