This disclosure relates to multilayer packaging films and methods of producing the same. The multilayer packaging films are paper-based and have a total composition comprising greater than or equal to 80 %, by weight, of a paper component. The multilayer packaging films are easily recyclable by repulping yet retain high-performance packaging characteristics including maintaining permeability performance and controlling the rate of ripening of a living food product, such as a cheese product. For example, the cheese product may include, but is not limited to, a soft cheese and / or a respirable cheese.

The present disclosure provides a home compostable extrusion coated substrate comprising a paperboard substrate having at least a first side and a layer of extrusion coating applied over at least a portion of the first side. The extrusion coating is comprised of from about 30 to about 99.5 weight percent of at least one poly(hydroxyalkanoate) and from about 5 weight percent to about 69.5 weight percent of at least one compostable polymer selected from the group consisting of poly(lactic acid), poly(caprolactone), poly(ethylene sebicate), poly(butylene succinate), poly(butylene succinate-co-adipate), poly(butylene adipate terephthalate), and mixtures thereof. Preferably, according to the present disclosure, the extrusion coated substrate is also home compostable as determined by ASTM D6868.

The present disclosure relates to tissue products comprising crosslinked fibers. The tissue products generally have good formation, such as a Formation Index greater than about 20, strength, such as geometric mean tensile strengths greater than about 700 g / 3" and high bulk, such as sheet bulks greater than about 10 cc / g. Unlike many prior art crosslinked fibers, the crosslinked softwood pulps of the present invention, which are preferably prepared using a glyoxal based crosslinking reagent, are readily dispersible in water and have relatively low degrees of kink and curl. As such, the fibers are well suited for forming wet-laid tissue products and more particularly wet-laid tissue products having improved physical properties, such as improved bulk.

To provide: an oil-resistant agent composition which can provide paper with excellent oil resistance and, when necessary, excellent water resistance; an oil-resistant paper; and a production method of paper.SOLUTION: Provided is an oil-resistant agent composition comprising a hydrocarbon group-containing polymer, the polymer having a repeating unit formed from a monomer containing a C1-40 hydrocarbon group and an NH group-containing group in an amount of 80 or more wt.% relative to the polymer. The hydrocarbon group-containing polymer preferably has (a) a repeating unit formed from an acrylic monomer having a C1-40 hydrocarbon group and an NH group-containing group and (b) a repeating unit formed from an acrylic monomer having a hydrophilic group.SELECTED DRAWING: None

A paper oil-resistant agent composition containing a hydrocarbon group-containing polymer having a repeating unit formed from a monomer having a hydrocarbon group having 7 to 40 carbon atoms and an NH group-containing group in an amount of 80% by weight or more based on the polymer. Also disclosed is an oil-resistant paper to which the hydrocarbon group-containing polymer in the paper oil-resistant agent composition adheres, a method for producing paper which includes treating paper with the paper oil-resistant composition, and a method for producing molded pulp which includes filling a mold with the paper oil-resistant agent composition and a pulp slurry, and molding the pulp.
