Adhesive for tamper evident seals

An adhesive resin composition consisting essentially of:

• (A) 50 to 90 wt % ethylene-vinyl acetate polymer having a vinyl acetate content of greater than 7 wt % and less than 20 wt % of the total ethylene-vinyl acetate polymer, an ethylene-acrylate polymer or mixtures thereof;
• (B) 10 to 50 wt % of a styrene homopolymer, or a styrene copolymer derived from:
• 4-n-butylstyrene;
• 4-t-butylstyrene;
• 2,4-diisopropylstyrene;
• 2,5-dimethylstyrene, hydroxystyrene;
• 3,4-diethylstyrene, 2-hydroxymethylstyrene;
• 4-methylstyrene;
• or 2-methylstyrene, with the weight percent being based on components (A) and (B) and
• (C) optionally, one or more modifying polymers produced by means of a Ziegler-type catalyst or a metallocene type catalyst and having a melt flow rate of 0.1 to 50 g/10 min., a density of about 0.820 to 0.970 g/cc and a melting point of about 60.degree. to 170.degree. C., said modifying polymers being a member of the group consisting of:
• an ethylene homopolymer, an ethylene copolymer;
• propylene homopolymer and a propylene copolymer.
