ANTIFOGGING RESIN SHEET

摘要

PROBLEM TO BE SOLVED: To obtain a resin sheet representative to a biaxially stretched polystyrene resin showing an antifogging effect superior to the conventional one wherein waterdrops adhering to the inside of a lid are extremely less, food contents can be clearly seen without cloudiness, the state can be maintained with transparency and no adherence when keeping as the lid of a food package container at a low or high temperature. SOLUTION: A antifogging resin sheet comprises coating the surface by a mixture of a polyglycerin fatty acid ester (A) and a diglycerin fatty acid (B). Preferably the antifogging resin sheet comprises coating the surface by a mixture wherein a mixing ratio (weight ratio) A:B of the polyglycerin fatty acid ester (A) and the diglycerin fatty acid (B) is 90-20:10-80.
