Abstract
A film for food packaging includes a resin composition comprising a vinyl chloride-based resin (A); a plasticizer (B); and an anti-fogging agent (C), wherein the composition comprises 1.5 parts by mass to 4.0 parts by mass of a diglycerin ester, 0.1 part by mass to 1.5 parts by mass of a glycerin monoester, and 0.1 part by mass to 3.0 parts by mass of an ethylene oxide adduct as the anti-fogging agent (C) relative to 100 parts by mass of the vinyl chloride-based resin (A).
Claims9
A film for food packaging, the film comprising a resin composition comprising:
- a vinyl chloride-based resin (A);
- a plasticizer (B);
- and an anti-fogging agent (C), comprising relative to 100 parts by mass of the vinyl chloride-based resin (A):
- 2.4 parts by mass to 4.0 parts by mass of a diglycerin ester,
- 0.1 part by mass to 1.5 parts by mass of a glycerin monoester, and
- 0.1 part by mass to 3.0 parts by mass of an ethylene oxide adduct.
A method for packaging food using a film for food packaging comprising:
- a vinyl chloride-based resin (A);
- a plasticizer (B);
- and an anti-fogging agent (C), comprising relative to 100 parts by mass of the vinyl chloride-based resin (A):
- 2.4 parts by mass to 4.0 parts by mass of a diglycerin ester,
- 0.1 part by mass to 1.5 parts by mass of a glycerin monoester, and
- 0.1 part by mass to 3.0 parts by mass of an ethylene oxide adduct,
- the method comprising:
- forming the film for food packaging in a form of a roll having a width of 200 mm to 800 mm;
- loading the roll into an automatic packaging machine and unwinding the film in the form of the roll at a speed of 300 mm/second to 2,000 mm/second from the automatic packaging machine;
- and
- packaging food or a container containing food by wrapping the unwound film for food packaging around the food or the container containing food.
