A high-transparence fiberglass paper includes vegetable parchment which is successively coated with a base layer, a second layer and a protective layer on both sides. The base layer and protective layer are prepared using water-based paints, while the second layer is prepared using UV ink through curing. The transparency and surface smoothness of the fiber is thereby greatly improved. Through treatment on the both surfaces, the paper can be processed into a light and smooth paper, with a surface smoothness of both sides more than 200 s, just like hyaline paper.

A method of forming glass-like sheets using date palm seeds is provided. The method includes milling date palm seeds to form a powder. The powder is compressed to form discs, after which the discs are immersed in a delignification solution followed by removal from the delignification solution and washing. The discs formed from the date palm seed powder are immersed in a bleaching solution until a change in color is observed from opaque to transparent. The transparent discs thus formed are then hardened through application of an epoxy resin. The initial grinding procedure may be substituted by an initial slicing step of the date palm seeds in a similar method of forming the glass-like sheets.

A method for fabricating emulated wood with pores and fibers, comprising: immersing a plurality of synthetic fibers configured parallel in a plane into a resin so that the resin is coated on the surfaces of the plurality of synthetic fibers and in the gaps between the plurality of synthetic fibers; placing the plurality of synthetic fibers between two sheets, wherein the two sheets are planar sheets made from a uniform composition comprising a thermoplastic elastomer, a foaming agent, and a crosslinking agent; carrying out a heat-press process on the two sheets so that the foaming agent undergoes microcellular foaming and forms dense closed pores in the two sheets, and so that the composition on inner surfaces of the two sheets expands towards the plurality of synthetic fibers and penetrates through the gaps between the plurality of synthetic fibers; and cooling the two sheets to yield an emulated wood board.

Highly transparent (up to 92% light transmittance) wood composites have been developed. The process of fabricating the transparent wood composites includes lignin removal followed by index-matching polymer infiltration resulted in fabrication of the transparent wood composites with preserved naturally aligned nanoscale fibers. The thickness of the transparent wood composite can be tailored by controlling the thickness of the initial wood substrate. The optical transmittance can be tailored by selecting infiltrating polymers with different refractive indices. The transparent wood composites have a range of applications in biodegradable electronics, optoelectronics, as well as structural and energy efficient building materials. By coating the transparent wood composite layer on the surface of GaAs thin film solar cell, an 18% enhancement in the overall energy conversion efficiency has been attained.

The invention relates to a coated paper, more particularly a translucent coated paper, comprising a base paper and a coating color layer applied thereto, wherein the coating color layer comprising a least one polymer and the coated paper having an opacity in the visible of less than 60%; a method for producing a coated paper of this kind, the use of said coated paper as a packaging material and to packaging comprising the coated paper.

The invention relates to a supercalendered Kraft paper production for a release liner, which contains both non-recycled bleached chemical pulps and recycled pulp produced from release liner supercalendered Kraft paper. When highly specific raw material is used for recycling, the characteristics of the recycled pulp may be adjusted already upon recycling. The recycled pulp obtained from supercalendered Kraft paper that has been used as a substrate of a release liner may be used without further refining for manufacturing supercalendered Kraft paper. Excessive refining can thus be avoided and the compatibility of the recycled pulp may be optimized for supercalendered Kraft paper production. The non-recycled pulps may be refined less, as well. This leads to positive effects in supercalendered Kraft paper manufacturing process, such as improved dewatering and energy efficient drying. The produced paper demonstrates reduced shrinkage and improved dimensional stability, while maintaining sufficient quality for use as a substrate for a release liner. A supercalendered Kraft paper with improved sustainability is produced.
