PROBLEM TO BE SOLVED: To provide a biodegradable heat sealing lacquer composition exhibiting blocking resistance without detriment to transparency, adhesive properties and adhesion. SOLUTION: The heat sealing lacquer composition comprises a biodegradable polyester (A), which contains 70-100 mass% of a lactic acid residue having a molar ratio (L/D) of the L-lactic acid residue to the D-lactic acid residue of 0.5-30 and has a reduced viscosity of 0.3-1.5 dl/g, and a terpene compound (B), where the amount of the terpene compound (B) is within 0.1-50 pts. mass based on 100 pts. mass of the biodegradable polyester (A).
