Abstract

Methods and apparatus for vacuum forming a meat tray using a slurry. The slurry comprises: a moisture barrier comprising AKD in the range of about 4% by weight; a fiber base comprising bagasse; and an oil barrier comprising a water-based emulsion in the range of about 1.5% by weight.

Claims (22)

1. A fiber-based slurry for use in vacuum forming a meat tray, the slurry comprising:

a fiber base of about 70% softwood and about 30% bagasse;

a moisture barrier; and

an oil barrier;

wherein the moisture barrier is in a range of about 1%-4% by weight and the oil barrier is in a range of about 1%-4% by weight.

2. The slurry of claim 1 , further comprising a strength additive in a range of 1.5%-4% by weight.

3. The slurry of claim 2 , wherein:

the moisture barrier comprises alkyl ketene dimer (AKD) in an amount of about 4% by weight; and

the oil barrier comprises a water based emulsion in an amount of about 1.5% by weight.

4. A meat tray made from the slurry of claim 3 .

5. A fiber-based slurry for use in vacuum forming a meat tray, the slurry comprising:

a moisture barrier; and

an oil barrier;

wherein the moisture barrier is in a range of about 1%-4% by weight and the oil barrier is in a range of about 1%-4% by weight.

6. The slurry of claim 5 , wherein the moisture barrier comprises alkyl ketene dimer (AKD).

7. The slurry of claim 5 , wherein the oil barrier comprises a water based emulsion.

8. A meat tray made from the slurry of claim 5 .

9. A slurry for use in vacuum forming a meat tray, comprising:

a moisture barrier comprising alkyl ketene dimer (AKD) in an amount of about 4% by weight;

a fiber base comprising bagasse; and

an oil barrier comprising a water-based emulsion in an amount of about 1.5% by weight.
