Title:
FILM CUTTER
Document Type and Number:
WIPO Patent Application WO/2011/010576
Kind Code:
A1
Abstract:
Provided is a film cutter using a lactic acid-based resin as a material, wherein the film cutter has excellent cutting properties, can be easily attached to a paper storage container, and can provide a sufficient adhesion strength. The film cutter is formed of a laminate composed of a layer (I) which contains 70 parts by mass to 100 parts by mass of a lactic acid resin (A-1) having a quantity of heat of crystal fusion (∆Hm) not less than 30J/g, and 0 parts by mass to 30 parts by mass of inorganic fine particles (B), and a layer (II) which is formed on at least one surface of the layer (I) and which contains 51 parts by mass to 95 parts by mass of a lactic acid resin (A-2) having a quantity of heat of crystal fusion (∆Hm) between 0 J/g and 25 J/g, and 5 parts by mass to 49 parts by mass of an ethylene copolymer (C). The laminate is stretched in at least one direction.
