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.

Container insulation including a batt comprised of large paper particles, at least 90% of which by weight are greater than 10 mm in diameter. Less than 5% by weight binder fibers are used, which have a length of at least 20 mm. Most preferably, no binder fibers are used. Where the batts are faced with paper, the paper is coated with a biodegradable coating. The resulting product is repulpable and recyclable in accordance with Fiber Box Association (FBA) testing protocols.

To provide a cellulose fiber molded product having improved tensile elastic modulus, preferably a cellulose fiber molded product also having improved tensile strength, and a method for manufacturing the same. A cellulose fiber molded product contains cellulose fibers as the main component, in which the cellulose fibers contain pulp and defibrated fibers, and the defibrated fibers contain microfibrillated cellulose. For manufacturing the molded product, a cellulose fiber slurry is prepared using the pulp and the defibrated fibers, wet paper is formed from the cellulose fiber slurry, and the wet paper is dehydrated, pressurized, and heated. At this time, as the defibrated fibers, microfibrillated cellulose, or microfibrillated cellulose and cellulose nanofibers are used.
