A wet blank flipping method for manufacturing pulp molded products, which follows these steps: after the wet blank is formed in the suction filtration forming mold, it is transferred to the hot-pressing shaping device for hot-press drying and shaping to create pulp molded products, characterized in that: said transfer is done using a first wet blank transfer device and a second wet blank transfer device to move the wet blank from the suction filtration forming mold to the hot-pressing shaping device; wherein, the first wet blank transfer device extracts the wet blank from the suction filtration forming mold and transfers it to the second wet blank transfer device, which then moves the wet blank to the hot-pressing shaping device.

Pressware products made from paperboard and methods for making same. The product can include a paperboard substrate and a compostable barrier coating, as determined by ASTM D6868-19, that is at least partially disposed on the paperboard substrate. The product can also include a paperboard substrate and a first compostable coating at least partially disposed on the paperboard substrate. The first compostable coating can include clay particles and less than 50 wt % binder, based on the total weight of the first compostable coating, wherein the binder is compostable, as determined by ASTM D6868-19. A second compostable barrier coating, as determined by ASTM D6868-19, can be at least partially disposed on the first compostable coating. The resulting pressware product is compostable, as determined by ASTM D6868-19.

Method for producing of a sound-absorbing panel, including a step of preparing a predetermined amount of cellulose fibres and a step of immersing the cellulose fibres in a first water basin to form a cellulose pulp. The method then includes a step of preparing a predetermined amount of textile fibres and a step of mixing, in water, the cellulose pulp with the textile fibres to obtain a final pulp and a step of depositing the final pulp on a forming mould. The method then includes a step of pressing at least the final pulp in order to cause an at least partial removal of the water contained in the final pulp making a fibre mat and a step of drying the fibre mat so as to cause evaporation of the water remained in the fibre mat making a sound-absorbing panel.

The invention relates to uncoated, fiber/starch composite materials manufactured without the use of fluorochemicals or additional binders that offer superior oil and grease resistance properties. Addition of an internal sizing agent in the preparation of the fiber/starch composite materials results in superior hot water and cold water resistance properties. The fiber/starch composite materials may be used for the manufacture of food service containers. The invention also relates to methods of preparation of the fiber/starch composite materials.

An egg carton and method and apparatus for forming an egg carton. A main body of the egg carton may be made of a single sheet of material and folded or otherwise bent to form the majority of the carton's interior space. Partition walls may be engaged with slots formed in the main body to define separate storage areas of the interior space as well as help hold the main body in the desired configuration. Hooks on the sides of the partition walls may engage with openings in the main body to secure the main body to the partition walls.
