A pulp mold includes a mold main body extending along a longitudinal axis and having an inner surface that defines a chamber, an outer surface opposite to the inner surface, and a plurality of channel grooves extending inwardly from the outer surface toward the inner surface and extending along a length of the outer surface. The chamber is divided into a plurality of chamber sections decreasing in diameters gradually and upwardly from the opening along the longitudinal axis. Each channel groove does not communicate with the chamber. A plurality of air holes extend from the outer surface to the inner surface, pass through the channel grooves, and communicate the chamber with the outside.

A tool for a thermoforming process to form a moulded product from wet pulp fibre material includes two or more moulds each having a moulding surface, an actuator assembly, and a fluid extraction system. At least one of the moulds is displaceable by the actuator assembly between first and second positions and has fluid extraction paths extending through the mould to transport fluid away from the moulding surface. One of the moulds has a first layer that is substantially rigid to form a support member and is in communication with a heating subsystem of the fluid extraction system, and a second layer that is, in use of the tool, between the first layer and the wet pulp fibre material. The second layer is formed of a material that has interconnected internal voids forming part of the fluid extraction paths and has a lower heat transfer coefficient than the first layer.

A container or lid may have a body of molded cellulose, the body of molded cellulose defining one or more walls. The wall has an outer surface and an inner surface. A depression is in the outer surface of the wall or walls. One or more labels, is or are embedded in the depression in the outer surface of the wall. A method for labelling a container or lid having a cellulose body may also be provided.

The present document discloses a tool or tool part for use in a process of molding a product from a pulp slurry. The tool or tool part comprises a self-supporting tool wall portion having a product face, for contacting the product, and a back face on the other side of the wall relative to the product face. The tool wall portion presenting pores, which are provided by a plurality of channels extending through the tool wall portion, from the product face to the back face. The channels are straight or curved with no more than one point of inflection.
