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.

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.
