<P>PROBLEM TO BE SOLVED: To provide a packaging bag with draining function which does not easily allow food enter a hook-and-loop fastener installed on an opening section when putting in/taking out food, is provided with sufficient draining function, and can sufficiently discharge steam from the hook-and-loop fastener when heated by a microwave oven. <P>SOLUTION: The packaging bag made of synthetic resin sheets is provided with two mushroom hook-and-loop fasteners installed along the opening of the packaging bag in a way that they are engaged with each other. Both two hook-and-loop fasteners are provided with two or more mushroom engaging element lines that extend from one end of the opening to the other end. The mushroom engaging elements are each formed of a stem section (S) and a cap section (M) expanding over the stem section. The cap section (M) expands beyond the stem section (S) in a direction perpendicular to the engaging element line direction (Q direction) but the cap section (M) does not stretch out in the engaging element line direction (P direction) and is provided with approximately the same width from the stem section (S) up to the end of the cap section. <P>COPYRIGHT: (C)2011,JPO&INPIT |
