Abstract
Disclosed are packaged fibrous material bales and methods for packaging fibrous materials such as cellulose acetate tow bales. The packaged fibrous material bale may comprise a compressed fibrous material enclosed in packaging. The packaging may comprise an upper sheet and a lower sheet comprising a tab. After the residual forces in the packaged bale have equilibrated following pressing, greater than 99% of the surface area of the bale is enclosed by the packaging.
Claims18
A packaged fibrous material bale, comprising:
- a) a fibrous material bale having an upper surface, a lower surface, and side surfaces, wherein the fibrous material is cellulose acetate tow;
- and
- b) a packaging enclosing at least 99% of surface area of the fibrous material bale, the packaging comprising:
- i) an upper sheet enclosing the upper surface;
- and
- ii) a lower sheet enclosing the lower surface of the fibrous material bale and a portion of the side surfaces,
- a) wherein the lower sheet comprises a corner fold enclosing at least a portion of one of the side surfaces;
- b) wherein the lower sheet comprises at least one tab located at or proximate to the corner fold;
- and
- c) wherein the at least one tab covers at least a portion of a corner of the bale;
- c) wherein the packaged fibrous material bale is substantially flat on the upper surface and the lower surface.
A method for packaging a cellulose acetate tow bale, the method comprising:
- a) placing fibrous material between an upper sheet and a lower sheet, wherein the lower sheet comprises at least one tab along a longitudinal length of the lower sheet and wherein the fibrous material is cellulose acetate tow;
- b) compressing the fibrous material in a press to form a fibrous material bale;
- c) enclosing the surface area of the fibrous material bale with packaging comprising the upper sheet and the lower sheet;
- i) wherein at least a portion of the lower sheet comprising the at least one tab is folded around at least one side of the fibrous material bale to form a corner fold;
- and
- ii) wherein the at least one tab covers at least a portion of a corner of the bale;
- d) securing the packaging around the fibrous material bale to form a packaged fibrous material bale;
- wherein the packaged fibrous material bale is substantially flat on an upper surface and a lower surface;
- and
- wherein at least 99% of the surface area of the fibrous material bale is enclosed by the packaging after the packaged fibrous material bale is stored for at least 48 hours.
