ABSTRACT:
A method of making and filling a plastic bag includes the steps of providing a bag having a plurality of microperforations; filling the bag with a powdered product; securing the bag; removing at least a portion of entrapped air in the bag through the microperforations; and sealing the microperforations. A product includes a bag configured for being formed from a plastic film into which a plurality of microperforations have been created. The bag contents include less air than that present in the bag when the top and the bottom were secured, at least a portion of the air sealed inside the bag having been expelled through the microperforations. A sealant is used for sealing the microperforations.
