ABSTRACT:
A paper bag of the type found in grocery stores which is reinforced by a plurality of narrow pleats extending lengthwise of the bag, the bag having corner defining pleats and additional pleats intermediate the corners of the bag, the pleats being folded down and secured to the bag material, preferably with the intermediate pleats adhered in a manner which permits them to expand under load, the pleats adding strength to the bag and permitting the use of lighter weight paper stock, thereby achieving savings in paper requirements as well as increased bag strength.
