Abstract
The invention is directed to a process to prepare a three-dimensional shaped biodegradable pulp product by (b) pressing a 3D product made of biodegradable pulp which product is coated with a water-resistant compound having a melting temperature of above 40° C. in a mould at a temperature above the melting temperature of the water-resistant compound, and (c) releasing the product from the mould and reducing the temperature to below the melting temperature of the water-resistant compound.

Process to prepare a three-dimensional shaped biodegradable pulp product by
- (b) pressing a 3D product made of biodegradable pulp which product is coated with a water-resistant compound having a melting temperature of above 40° C. in a mould at a temperature above the melting temperature of the water-resistant compound, and
- (c) releasing the product from the mould and reducing the temperature to below the melting temperature of the water-resistant compound.
A planting aid product comprising
- a container comprising an annular compartment for water composed of a biodegradable pulp with a downwardly tapering outer wall and an upwardly tapering inner wall defining a central open channel, where in use a plant is positioned, wherein the annular compartment is closed at its lower end and open at its upper end,
- wherein a circular lid closes the upper open end of the annular compartment and wherein the lid has a central opening which opening aligns with the central open channel of the container, and
- wherein the downwardly tapering outer wall and an upwardly tapering inner wall are coated by a water-resistant compound.
A planting aid product comprising:
- a container comprising an annular compartment for water composed of a biodegradable pulp with a downwardly tapering outer wall and an upwardly tapering inner wall defining a central open channel, where in use a plant is positioned, wherein the annular compartment is closed at its lower end and open at its upper end;
- and
- wherein a circular lid closes the upper open end of the annular compartment and wherein the lid has a central opening which opening aligns with the central open channel of the container;
- obtained by a process comprising:
- (a) spraying a water-resistant compound having a melting temperature of above 40° C. to coat a surface of a starting three-dimensional shaped biodegradable pulp product;
- (b) pressing the starting three-dimensional shaped biodegradable pulp product in a mould at a temperature above the melting temperature of the water-resistant compound;
- and
- (c) releasing the product from the mould and reducing the temperature to below the melting temperature of the water-resistant compound.
