The invention discloses a mildewproof and antibacterial coating film which comprises a substrate, a coating layer on the surface of the substrate and a primer layer between the coating layer and the substrate. The coating layer is a coating formed by coating the surface of the substrate with a modified acrylic coating and drying, and the primer layer is composed of a hydrophobic resin binder. The mildewproof and antibacterial coating has excellent low-temperature heat sealability, high heat sealing strength, quite high transparency and satisfactory glossiness and can effectively realize mildewproof and antibacterial effects. 本发明公开的种防霉抗菌涂布膜，包括基材、基材表面的涂料层、涂料层和基材之间的底胶层，所述涂料层是由改性丙烯酸涂料涂覆在基材表面并烘干后形成的涂层，所述的底胶层由斥水性树脂粘结剂构成。该防霉抗菌涂布膜具有优异的低温热封性能和较好的热封强度，并具有非常好的透明度和令人满意的光泽性能，且该防霉抗菌涂布膜能有效的达到防霉抗菌的效果。
