PROBLEM TO BE SOLVED: To prepare a double-sided adhesive tape which is useful for sealing and can not only smoothly remove air from a bag when the packaging bag, an envelope or the like, is sealed, but also is advantageous in producing the double-sided adhesive tape and the packaging bag themselves. SOLUTION: This double-sided adhesive tape A for sealing is obtained by forming adhesive layers on both the surfaces of a flexible taped substrate 1. Therein, an adhesivity-reducing or eliminating cover layer 3 for generating air paths in a state crossing the width direction of the tape is formed on a part of the surface layer of at least one of the adhesive layers 2, 4.
