Methods and apparatus for manufacturing fiber-based meat containers
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.
1. A fiber-based slurry for use in vacuum forming a food tray, the slurry comprising:
a fiber base comprising 50% to 95% old corrugated containers (OCC);
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 1 , wherein the moisture barrier is about 4% by weight.
4. The slurry of claim 1 , wherein the oil barrier is about 1.5% by weight.
5. The slurry of claim 1 , wherein the moisture barrier comprises alkyl ketene dimer (AKD).
6. The slurry of claim 1 , wherein the oil barrier comprises a water-based emulsion.
7. A fiber-based slurry for use in vacuum forming a food tray, the slurry comprising:
0.5% to 30%: newsprint (NP);
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.
8. The slurry of claim 7 , further comprising a strength additive in a range of 1.5%-4% by weight.
9. The slurry of claim 7 , wherein the moisture barrier is about 4% by weight and the oil barrier is about 1.5% by weight.
