A fibrous product for use in a variety of applications. The fibrous product particularly well suited for use in thermoforming 3-D articles such as food packaging, automotive parts, and electronic packaging. The fibrous product can be biodegradable, recyclable, and compostable. The fibrous product can contain a first plant fiber that is a non-wood fiber.

There is provided a use of a pulp mixture for forming a container in a mould, which pulp mixture comprises: 65-90%, such as 70-84%, by dry weight of a first pulp having a Schopper-Riegler (SR) number of below 48, preferably below 40, more preferably below 30; and 10-35%, such as 16-30%, by dry weight of a second pulp having a Schopper-Riegler (SR) number of 60-90, preferably 70-90, more preferably 77-90. A pulp mixture and a method of producing a pulp mixture are also provided.

A fiber-based, plastic-free drinking cup is formed by providing a fiber-based slurry comprising a hydrophobic additive and a strength additive, then forming a drinking cup component by compressing and drying the fiber-based slurry in a form press assembly having an internal shape characterized by a conic frustum. The fiber-based slurry may include a dry pulp mixture of virgin fiber and recycled fiber, the hydrophobic additive is 1.0-10.0% of the dry pulp weight, and the strength additive is 1.0-10.0% of the dry pulp weight. In particular, the fiber-based slurry may include about 50% bleached hardwood, about 50% bleached softwood, about 2.5% strength additive, and about 3.5% hydrophobic additive by dry pulp weight.

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.

Disclosed herein are perforated structures and methods for their manufacture. The perforated structures comprise zones of perforations, which are optimized for controlling the flow of gas or liquid through the perforated structure. The perforated structures may be configured for use as molds and for manufacture by additive manufacturing processes.

In one example, a process for manufacture of a pulp-based dispensing capsule is disclosed. The process includes providing one or more mesh tool sets that are each contoured to one or more preform shapes of the dispensing capsule. Note that each preform shape is a partially shaped version of a final form shape of the pulp-based dispensing capsule. The process also includes providing a holding tank containing a suspension that includes water and pulp fibres; and arranging the mesh tool sets to allow immersion into and withdrawal of the mesh tool sets from the suspension. The process also includes applying a vacuum to the mesh tool sets so as to draw pulp fibres from the suspension onto the mesh tool sets while immersed in the suspension to form a preform pulp fibre mat; and in a second toolset, deforming each preform shape in the preform pulp fibre mat towards the final form shape by the application of pressure.
