The present invention provides a packaged cementitious product including a bag formed of a polymeric material. The bag has first and second sealed ends. The first end has a first tab extending therefrom defining at least one aperture therethrough so that the first tab defines a first handle. The second end has a second tab extending therefrom defining at least one aperture therethrough so that the second tab defines a second handle. A cementitious product is sealed within the bag, and wherein the first and second handles facilitate the handling of the packaged cementitious product.

That which is claimed: 1. A method for packaging cementitious material using an automated machine, the method comprising: providing a roll of tubular polymeric film material; dispensing the tubular polymeric film material using the automated machine; sealing the tubular polymeric film to form a first seal; cutting the tubular polymeric film material at a predetermined distance from the first seal to form a bag, the bag comprising first and second ends, the first end comprising the first seal and defining a first tab extending therefrom; sealing the distal edge of the first tab; forming at least one aperture through the first tab so that the first tab defines a first handle; filling the bag with a predetermined amount of cementitious material; cleaning the inside edges of the second end of the bag; sealing the second end of the bag so as to form a second tab extending therefrom; sealing the distal edge of the second tab; forming at least one aperture through the second tab so that the second tab defines a second handle; and wherein, the at least one aperture in the first tab and the at least one aperture in the second tab are at least partially sealed so that the first and second handles together are capable of supporting at least approximately twenty-nine (29) pounds of weight without any further reinforcement. 2. A method for packaging cementitious material according to claim 1 wherein said first forming step comprises heating a die and forming the at least one aperture through the first tab using the heated die. 3. A method for packaging cementitious material according to claim 2 wherein said heating step comprises heating the die to between approximately 420° F. to approximately 460° F. 4. A method for packaging cementitious material according to claim 1 wherein the bag has first and second sides, at least a portion of at least one of the first and second sides defines a textured surface. 5. A method for packaging cementitious material according to claim 1 wherein said polymeric material comprises a blend of high density polyethylene and linear low density polyethylene. 6. A method for packaging cementitious material according to claim 1 wherein said polymeric material has a thickness of about 4 to 6 mil. 7. A method for packaging cementitious material according to claim 1 wherein said first tab defines a plurality of apertures therethrough. 8. A method for packaging cementitious material according to claim 1 wherein said second forming step comprises forming a plurality of apertures through the second tab. 9. A method for packaging cementitious material according to claim 1 wherein said second forming step comprises heating a die and forming the at least one aperture through the second tab using the heated die. 10. A method for packaging cementitious material according to claim 9 wherein said heating step comprises heating the die to between approximately 420° F. to approximately 460° F. 11.
