Gel packaging bag

Abstract

This product is a packaging bag consisting of two inner bags filled with gel and an outer bag that covers the two inner bags. This product is used with the gel sealed in the inner bags. For example, when thawing a frozen food or other object in a microwave oven, the object can be sandwiched between the two inner bags and the microwave oven is turned on to ensure uniform thawing. Examples of gels include a gel-like substance made by mixing water-absorbent polymers with water, or a viscous substance made by mixing carboxymethyl cellulose (CMC) with water. As shown in the reference perspective view showing the sealed portion, the gray-colored areas are sealed, and the outer bag is sealed at the perimeter and center along the boundaries between the two inner bags. The outer bag has through-holes on the front and back of the left and right ends that serve as steam vents.
