1. A method for creating and filling a paper bag with a covered window cutout configured to withstand moisture from product contained therein, the method comprising:
receiving a roll of calendared paper at a standard printing machine;
printing, with the standard printing machine, an adhesive onto a surface of the roll of calendared paper in a predetermined pattern, wherein the adhesive is applied in register, wherein the predetermined pattern includes application of the adhesive onto the calendared paper to form a border around a perimeter of a window to be cut out of the paper for each of a plurality of windows to be cut out of the roll of calendared paper, creating a roll of printed calendared paper, wherein the adhesive is a water-based, heat-activated polyvinyl acetate with low viscosity;
cutting and removing a window portion of the paper from prescribed positions along the roll of paper such that once removed the window is created within the adhesive applied border of the paper for each of the plurality of windows to be cut out of the roll of calendared paper, creating a plurality of windows in the roll of calendared paper;
positioning a window covering to cover each of the plurality of windows and extend to the adhesive applied border for each window, wherein the window covering is a wood-based compostable scrim or a wood-based compostable glassine, further wherein the adhesive has also been pre-applied to all edges of the window covering to match with the adhesive applied to the border of the window of the paper for each of the plurality of windows;
heat sealing each window covering along the roll of printed calendared paper to the printed calendared paper, wherein the adhesive printed on the calendared paper is sealed to the adhesive pre-applied to each window covering;
receiving the roll of printed calendared paper at an automated filling machine to form and fill the roll of printed calendared paper to create individual bags filled with a product;
forming a body of the bag by shaping the printed calendared paper and heat sealing a plurality of adhesive applied seams of the printed calendared paper to secure the body of the bag, wherein the adhesive is printed onto both corresponding sides of the plurality of seams such that the heat sealing adheres the adhesive of an adhesive applied seam to another adhesive applied seam;
filling the bag by automatedly adding product to the bag; and
repeating the steps performed by the automated filling machine until the roll of printed calendared paper is transformed into a plurality of formed, sealed, and filled bags.
