Biodegradable and compostable food packaging unit from a moulded pulp material, and method for manufacturing such food packaging unit
The present invention relates to a biodegradable food packaging unit from a moulded pulp material and a method for manufacturing such biodegradable packaging unit. The packaging according to the invention comprises a food receiving or carrying compartment, wherein the moulded pulp material comprises an amount of a biodegradable aliphatic polyester, wherein the food packaging unit is a compostable food packaging unit. In a preferred embodiment the amount of biodegradable aliphatic polyester is in the range of 0.5-20 wt. %, more preferably in the range of 1-15 wt. %.
1. A food packaging unit from a moulded pulp material, the packaging unit comprising a food receiving or carrying compartment, wherein the moulded pulp material comprises a mixture of a moulded pulp and a biodegradable aliphatic polyester, wherein the food packaging unit is a compostable food packaging unit and wherein the amount of biodegradable aliphatic polyester is in the range of 0.5 to 20 wt. %.
2. The food packaging unit according to claim 1 , wherein the amount of biodegradable aliphatic polyester is in the range of 2-10 wt. %.
3. The food packaging unit according to claim 1 , further comprising one or more further agents from a biodegradable aliphatic polyester.
4. The food packaging unit according to claim 1 wherein the biodegradable aliphatic polyester comprises an amount of one or more of PBS, PHB, PHA, PCL, PLA, PGA, PHBH and PHBV.
5. The food packaging unit according to claim 1 , wherein the unit biodegrades at a temperature in the range of 5 to 60° C.
6. The food packaging unit according to claim 1 , wherein the biodegradable aliphatic polyester is bio based.
7. The food packaging unit according to claim 1 , further comprising an amount of natural and/or alternative fibers.
8. A food packaging unit from a moulded pulp material, the packaging unit comprising a food receiving or carrying compartment, wherein the moulded pulp material comprises a mixture of a biodegradable aliphatic polyester and a moulded pulp, wherein the food packaging unit is a compostable food packaging unit, wherein the amount of biodegradable aliphatic polyester is in the range of 0.5-20 wt. %, wherein the biodegradable aliphatic polyester comprises an amount of one or more of PBS, PHB, PHA, PCL, PLA, PGA, PHBH and PHBV.
