Abstract
A coated plastic film possessing good printability slip properties, oxygen and moisture barrier properties and transparency which comprises applying to a plastic film a coating solution of a thermoplastic resin as base resin in which a synthetic resin of a network structure having a softening temperature above 100.degree. C. and being in the form of a fine powder are added, and drying thereafter.
Claims17
A coated plastic film possessing good printability, slip properties, oxygen and moisture barrier properties and transparency, comprising a plastic film and a coating thereon, said coating including a thermoplastic base resin and a crosslinked, electrostatically neutral synthetic resin in an amount of from 0.01-2 parts by weight per 100 parts by weight of said thermoplastic resin, said synthetic resin having a softening temperature of above 100.degree. C. and an average particle diameter of 1-20 microns.
A method of producing a coated plastic film having good printability, slip properties, oxygen and moisture barrier properties and transparency which comprises:
- dissolving a thermoplastic resin in a solvent liquid;
- dispersing in said solution 0.01-2 parts by weight per 100 parts of said thermoplastic resin of a crosslinked, electrostatically neutral synthetic resin having a softening temperature of about 100.degree. C. and an average particle size of 1-20 microns and being substantially insoluble in said solvent liquid;
- coating the surface of a plastic film with said dispersion;
- and
- thereafter drying said coated plastic film.
