Abstract
A packaging member (1, 80, 100) is provided with easy-opening means (7, 85, 107, 108) for allowing the packaging member to be opened easily, wherein the easy-opening means is either positionally or structurally improved. As one example, the packaging member is a packaging bag (1, 80), in which the easy-opening means serves as a tearing start point when opened with the use of the easy-opening means. The easy-opening portion is formed at a position slightly shifted inward from a perimeter edge of the packaging bag. As another example, the packaging member is a packaging container (100), in which the easy-opening means is structurally improved.
