A hanging device and methods of making the hanging device are shown and described herein. The hanging device may be a hook or a hanging device. The hanging device comprises: a) a first outer liner; b) at least one inner layer; and c) a second outer liner. For the hanging device, the first outer liner is at least partially disposed on the at least one inner layer and the second outer liner is at least partially disposed on the at least one inner layer, and the first outer liner, the at least one inner layer, and the second outer liner are laminated together. The hanging device may be comprised of a biobased material and/or a recycled material. The hanging device may be biodegradable.

A waterproof corrugated paper includes at least one stone paper medium and at least one stone liner paper, wherein the at least one stone paper medium includes a first fluting surface. A stone glue is utilized to adhere the at least one stone liner paper and several wave crests of the first fluting surface. The stone glue includes a linear polyolefin plastic material and an inorganic material. The linear polyolefin plastic material is 30 wt %-70 wt % based on the stone glue, and the inorganic material is 30 wt %-70 wt % based on the stone glue. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food. A manufacturing method, a manufacturing apparatus, and a usage of the waterproof corrugated paper are also provided in the present invention.

Articles and methods for archival raised image printing is disclosed. The process includes modifying an electronic image, printing the image on a paper substrate to form a printed substrate, applying the printed substrate onto a barrier substrate via an applicator such that the applicator creates a wall around the outer edge of the image, coating the printed substrate with a varnish composition, and drying the printed substrate in a humidity controlled environment. This configuration provides an efficient system of archival printing to print raised images on an article.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

The invention relates to the use of a surface size composition comprising at least one cellulose derivative selected from cellulose ethers, excluding carboxyalkyl celluloses, for providing compression strength for a fibrous web, such as paper, board or the like, preferably comprising recycled cellulosic fibres. The invention relates also to a method for surface sizing of paper, board or the like.

The disclosure is directed to methods of manufacturing protective packaging materials, as well as the protective packaging materials produced using the disclosed methods. These packaging materials can be biodegradable, compostable, and/or recyclable.

Provided is a wheat straw paper composite for a packaging material, comprising a first layer and second layer of wheat straw paper; and a layer of wheat flour film therebetween. Also provided is a laminate comprising at least three of the wheat straw paper composites, the first and second wheat straw paper composites in the form of a flat sheet, and the third wheat straw paper composite corrugated to include a plurality of flutes and positioned between the first and second wheat straw paper composite. Also provided is a system for packaging and physically protecting electronic devices in transit. The packaging system includes the laminate provided herein as an external protection container in combination with a corn foam insert that comprises a biodegradable cornstarch foam product comprising at least 60 wt % cornstarch, or a biodegradable expanded foam comprising a polylactic acid.

A compostable laminate for food wrap and method for making same. The wrap can include a first layer of paper material, a second layer of paper material, and a series of coatings between the paper materials. The coatings include a first flood coating having water and/or barrier properties, a second flood coating having water and/or oil barrier properties, and a third coating that only partially covers the second flood coating. None of the first, second and third coatings comprise a thermoplastic or polyolefin, and are made substantially from one or more biodegradable and/or compostable materials.

A protective product, such as, e.g., an envelope or pouch, is provided that includes at least one expanded slit paper sheet in an expanded state, and an embossed paper sheet facing the expanded slit paper sheet and fixed to the expanded slit paper sheet along at least a portion of a length in an expansion direction of the expanded slit sheet paper. In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.
