The present invention relates to the use of vacuum packaging and vacuum packaging techniques. Embodiments of the present invention include bales and packages comprising a sealed chamber having an internal volume at a pressure less than ambient atmospheric pressure. In alternate embodiments of the present invention, the internal volume of the package comprises a bulk material, a bulk fiber material, fibers or fibrous materials. Also disclosed are methods for packaging, packaging systems and apparatus for packaging.

1. A method of packaging fibers comprising the sequential steps of: a) providing a package having an open box-like configuration with a bottom wall, side walls, and an internal volume;b) placing fibers on the bottom wall of the package;c) compressing the fibers;d) sealing a top wall to the side wall
1. A method of packaging fibers comprising the sequential steps of: a) providing a package having an open box-like configuration with a bottom wall, side walls, and an internal volume;b) placing fibers on the bottom wall of the package;c) compressing the fibers;d) sealing a top wall to the side walls to seal the package, thereby defining a sealed chamber around the compressed fibers; ande) evacuating the internal volume through an evacuator, thereby defining an initial pressure in the sealed chamber; andf) releasing the compression;wherein the density of the bulk fibers in the sealed chamber is from 0.48 to 0.82 g/cm3;wherein the package has a substantially cuboidal shape; andwherein the top and bottom walls of the sealed chamber are substantially flat. 2. The method of claim 1, wherein the fibers comprise cellulose acetate fibers. 3. The method of claim 1, wherein the density of the bulk fibers in the sealed chamber is from 0.50 to 0.78 g/cm3. 4. The method of claim 1, wherein the walls provide one or more of a gaseous barrier, a moisture barrier, and an odor barrier. 5. The method claim 1, wherein the initial pressure in the sealed chamber is from 16,000 Pa to less than ambient atmospheric pressure. 6. The method of claim 1 wherein the initial pressure in the sealed chamber is from 40,000 Pa to 92,000 Pa. 7. The method of claim 1, wherein the initial pressure in the sealed chamber is from 50,000 Pa to 70,000 Pa. 8. The method of claim 1, wherein the height of the center of the top wall is less than 2.4% greater than the height of an edge of the top wall. 9. The method of claim 1, wherein the height of the center of the top wall is less than 0.8% greater than the height of an edge of the top wall. 10. The method of claim 1, wherein the difference in height between the edge of the top wall and a center point of the top wall is less than 5 cm. 11. The method of claim 1, wherein the difference in height between the edge of the top wall and a center point of the top wall is less 3 cm. 12. The method of claim 1, wherein the difference in height between the edge of the top wall and a center point of the top wall is less than 1 cm. 13. The method of claim 5, wherein the package maintains at least a partial vacuum for at least 2 days. 14. The method of claim 1, wherein the package comprises a pull tape designed to be pulled to tear open the chamber along a defined path. 15. The method of claim 1, wherein an easy open portion is provided in one or more walls.
