1. A plastic blow-molded barrel comprising:a barrel body having a top surface, a bottom surface, and four substantially identically shaped, convex side surfaces, each side surface connected to two adjacent side surfaces at rounded corners, the bottom surface and four side surfaces having a unitary construction; anda horizontal stiffening element that is formed as an indentation, located between said top surface and bottom surface, and runs along a circumference of the barrel body,wherein the convex side surfaces and the rounded corners impart an approximately square-shaped cross-section to the barrel body.2. The plastic blow-molded barrel according to claim 1, wherein the top surface, bottom surface, and four side surfaces have a unitary construction.3. The plastic blow-molded barrel according to claim 1, wherein the horizontal stiffening element is formed as one of a V-shaped indentation and a U-shaped indentation.4. A plastic blow-molded barrel comprising:a barrel body having a top surface, a bottom surface, and four substantially identically shaped, convex side surfaces, each side surface connected to two adjacent side surfaces at rounded corners, the bottom surface and four side surfaces having a unitary construction;a horizontal stiffening element that is formed as an indentation, located between said top surface and bottom surface, and runs along a circumference of the barrel body, anda thickened mold hoop emerging from a radially inner portion of the indentation and extending in a radially outward direction;wherein the convex side surfaces and the rounded corners impart an approximately square-shaped cross-section to the barrel body.5. The plastic blow-molded barrel according to claim 4, wherein a radially outermost portion of the mold hoop extends to an outer circumference of the barrel body.6. The plastic blow-molded barrel according to claim 4, wherein a radially outermost portion of the mold hoop extends beyond an outer circumference of the barrel body so that the mold hoop sticks out from the barrel body.7. The plastic blow-molded barrel according to claim 4, wherein the thickened mold hoop is provided at a level that is about 43% of a height of the barrel.8. The plastic blow-molded barrel according to claim 1, further comprising first and second side bungs, each side bung formed on the top surface adjacent to oppositely facing first and second of said four side surfaces.9. The plastic blow-molded barrel according to claim 1, further comprising a foot hoop extending around a circumference of the barrel body, the foot hoop configured to allow rolling of the barrel on a floor.10. A plastic barrel comprising:a barrel body having a top surface, a bottom surface, and four substantially identically shaped side surfaces, each side surface connected to two adjacent side surfaces at corners;an indentation located between said top surface and bottom surface, and running along a circumference of the barrel body, anda mold hoop emerging from a radially inner portion of the indentation and extending in a radially outward direction.11. The plastic barrel according to claim 10, wherein the top surface, bottom surface, and four side surfaces have a unitary construction.12. The plastic barrel according to claim 10, wherein the indentation is formed as one of a V-shape and a U-shape.13. The plastic barrel according to claim 10, wherein a radially outermost portion of the mold hoop extends to an outer circumference of the barrel body.14. The plastic barrel according to claim 10, wherein a radially outermost portion of the mold hoop extends beyond an outer circumference of the barrel body so that the mold hoop sticks out from the barrel body.15. The plastic barrel according to claim 10, wherein the mold hoop is provided at a level that is about 43% of a height of the barrel.16. The plastic barrel according to claim 10, further comprising first and second side bungs, each side bung formed on the top surface adjacent to oppositely facing first and second of said four side surfaces.17. The plastic barrel according to claim 10, further comprising a foot hoop extending around a circumference of the barrel body, the foot hoop configured to allow rolling of the barrel on a floor.18. The plastic barrel according to claim 10, wherein the side surfaces are convex.
