An aqueous biopolymer dispersion composition comprising: a biopolymer selected from the group consisting of: polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), polybutylene succinate adipate (PBSA), polylactic acid (PLA), poly(3-hydroxybutyrate) (PHB), polycaprolactone (PCL), poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH); poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), polyhydroxyalkanoate (PHA), and mixtures thereof; a stabilising agent selected from the group consisting of: polyvinyl alcohol, fatty alcohol ethoxylates, ethylene oxide/propylene oxide (EO/PO) block copolymers, salts of fatty acids and mixtures thereof; a rheology modifier; a cross linking agent; optional further ingredients; and water.

A paper laminate comprising a water-dispersible nanocomposite barrier against any permeation.

A water vapour-permeable and hot water-resistant paper made substantially of cellulose and of manufacturing additives required for cellulose production, such as pH-value adjusting agents based on acids and/or bases, the paper exclusively contains cellulose with fibre lengths of at least 2.0 mm as a length-weighted mean, in particular of at least 2.5 mm as a length-weighted mean, wherein the cellulose forming the paper is a cellulose ground to a consistency of 30-35% by high-consistency grinding and possibly to a consistency of 4-6% by low-consistency grinding, a proportion of fines in the paper is set at values smaller than 6.5% and the pH value is set in the pseudo-neutral range, in particular at values under 7.5, preferably at values between 6.6 and 7.4, and an elongation of the paper in the machine direction is ≤3%.

Polymer or polymer inks are used for reducing or eliminating harmful chemicals by offering a neutralizing chemical in the path of movement of the harmful chemicals. A neutralizing chemical responsive to the harmful chemical produces a harmless chemical as an output that is in the path of the harmful chemical and is opposite phase with the neutralizing chemical, preferably by 180 degrees, or is at least opposite in chemical compatibility to some extent. The neutralizing chemical can be suspended or combined with an inert carrier and preferably attenuates the harmful chemical concentration. The polymer ink can be applied to a media such as paper, (embossed or extruded) or polymer the same as paper but also in foam (open cell preferred) in order to obtain a decrease in the concentration of harmful gases. These forms can be utilized in air or liquid applications.

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

A heat sealable paper-based substrate is provided with at least the first surface covered with at least one primer coat and at least one topcoat over the primer coat, wherein: the primer coat is formed from a substantially wax-free aqueous dispersion of at least one polymer or copolymer, has a coefficient of thermal expansion equal to or less than about 200 μm/(m.Math.° C.) for at least one operating temperature, and has a complex viscosity of at least about 80000 poises at a heat seal temperature; the topcoat has a different composition than the primer coat and is formed from an aqueous dispersion of at least one thermoplastic polymer or copolymer, and has a complex viscosity of at least about 3000 poises at a heat seal temperature. The heat sealable paper-based substrate can be used to make articles to contain goods such as cold or hot beverages or food products.
