摘要
The invention relates to a food contact resealing label material which comprises a thin film substrate, an acrylic-acid pressure-sensitive adhesive and a silicone oil body paper/film. The oxygen permeability of the thin film substrate is lower than 2.0x10 -5m 3/m 2·d·Pa and the moisture-penetrability of the thin film substrate is lower than 2.0x10 -4kg (s·m 2); the acrylic-acid pressure-sensitive adhesive is designed on the lower surface of the thin film substrate wherein the residual of solvent ranges from 5mg/m 2 to RL value and the overall migration volume of the acrylic acid ranges from 6mg/kg to RL value; the silicone oil body paper/film is designed on the lower surface of the acrylic-acid pressure-sensitive adhesive. In addition, the invention further discloses a preparation method of the food contact resealing label material, a food contact resealing label prepared from the food contact resealing label material and an application of the food contact material to the food packaging. The oxygen permeability, moisture-penetrability, the residual of solvent, the overall migration volume of the acrylic acid and the isocyanate residue of food contact resealing label material can meet the requirements for food contact and food contact package.
