A cellulosic structure including a cellulosic substrate comprising a first major side and a second major side opposed from the first major side, an oil barrier layer on the second major side of the cellulosic substrate, and a water barrier layer on the second major side of the cellulosic substrate, wherein the oil barrier layer is positioned between the cellulosic substrate and the water barrier layer.

Disclosed is a method for manufacturing a base paper for eco-friendly paper cups and, more specifically, to a method for manufacturing a base paper for eco-friendly paper cups, the method enabling the manufacturing of a base paper for eco-friendly cups, which has excellent heat sealability, water resistance, and block resistance, facilitates recycling, and is biodegradable in nature.

Disclosed is a base paper for eco-friendly paper cups and, more specifically, to a base paper for eco-friendly paper cups, which is eco-friendly by having recyclability and biodegradability while retaining water resistance, oil resistance, heat sealability, and block resistance required as a base paper for paper cups.

The present disclosure provides an ink fluid set containing an aqueous pretreatment composition and an aqueous inkjet ink. This ink fluid set is particularly suitable for printing on offset coated media.

A cellulosic substrate includes a first major side and a second major side opposed from the first major side, a single polyolefin aqueous polymer dispersion barrier layer on the first major side of the cellulosic substrate, and at least one non-polyolefin aqueous polymer dispersion barrier layer between the single polyolefin aqueous polymer dispersion barrier layer and the first major side of the cellulosic substrate.

A coating structure for a sheet-like substrate is disclosed including cellulosic fibres and a sheet-like product. The structure includes at least one pre-coat layer and a top coat layer, where the pre-coat layer(s) and the top coat layer include 10-90 weight-% of a styrene (meth)acrylate copolymer which is polymerised in the presence of a stabiliser, and which has a glass transition temperature Tg20 C., preferably 15 C., more preferably 13 C. Furthermore, the pre-coat layer(s) includes a polysaccharide, such as starch, and the top coat layer includes 5-60 weight-% of at least one water-soluble coating binder, which is selected from polysaccharides and polyvinyl alcohols, as well as at most 5.0 weight-% of a cross-linker, which reacts with OH or COOH groups.

A coating for paperboard includes polyethylene outer layers and a polyethylene inner layer with calcium carbonate filler. In addition to the lower cost, benefits include a surprising better heat sealing behavior compared with a coating of polyethylene alone.

According to an example aspect of the present invention, there is provided a cost-effective method of producing cellulose based films by introducing an intense water removal system to the process, and cellulose based films thereof having improved properties.

Coatings for packaging materials and, more specifically, aqueous coatings for paperboard substrates and methods of applying the coatings. The aqueous coatings may include light blocking particles.

A method for fabricating shaped-paper products is introduced herein, which comprises at least one dredging-pulp step for forming a wet pulp made of paper-slurry materials, at least one pre-compression step for lightly compressing the wet pulp to form a first semi-finished product, at least one thermo-compression forming step for deeply compressing the first semi-finished product to form a second semi-finished product, and a surface-coating step of employing a product surface coating apparatus to coat a liquid coating materials onto at least one outer surface of the second semi-finished product, and thereby forming each of the shaped-paper products having a binding layer. With utilization of the present invention, an automatic coating can be applied high efficiently in a series of continuous production machines. This could not only shorten processing time and benefit a mass production thereof but also ensure a higher production yield and quality.
