The present invention relates to a process for manufacturing a barrier film, wherein the method comprises: providing an aqueous suspension comprising at least 70 weight-% highly refined cellulose pulp having an SR value of 70-95 and having a content of fibers having a length>0.2 mm of at least 10 million fibers per gram based on dry weight: forming a wet web; dewatering and/or drying to form a substrate; calendering said substrate in at least a first calender nip and a second calender nip; providing said substrate with at least one first layer of a barrier chemical to form a coated substrate, wherein each first layer has a coat weight of 0.5-5 gsm, and wherein a total coat weight on of the first layers is ?8 gsm, anddrying to form said barrier film having a thickness of <50 ?m. The invention relates also to a barrier film, a barrier film laminate with a polymer layer and a packaging material comprising the barrier film.

A photocurable composite hydrogel matrix precursor, a preparation method thereof and a scaffold with same. The photocurable composite hydrogel matrix precursor includes gelatin methacrylate, sodium alginate, sodium carboxymethyl cellulose and chondroitin sulfate, where the mass ratio of a photoinitiator to the gelatin methacrylate to the sodium alginate to the sodium carboxymethyl cellulose to the chondroitin sulfate is (0.2-0.3):(8-10):(1-3):(0.6-0.8):(0.05-0.07). By adoption of the precursor, a cell-loaded printing hydrogel scaffold can be obtained through an extrusion-based 3D bio-printing technology, and the scaffold is controllable in form, good in moldability, high in precision, and has good stability; the biocompatibility and bioactivity are high, so that a good growing environment can be provided for fibroblasts; and the preparation process is simple and can be completed within a short time, moreover, the porosity and mechanical performance of the 3D printing hydrogel scaffold can be adjusted by adjusting the raw material ratio.

The invention relates to a formaldehyde-free binder composition for mineral fibres comprising at least one phenol and/or quinone containing compound, and at least one protein.

The invention relates to a method of bonding together surfaces of two or more elements, whereby at least one of the two or more elements is a mineral wool element, said mineral wool element(s) being bound by a mineral wool binder, the method comprising the steps of providing two or more elements; applying an adhesive to one or more of the surfaces to be bonded together before, during or after contacting the surfaces to be bonded together with each other; curing the adhesive, wherein the adhesive comprises at least one protein; at least one phenol and/or quinone containing compound, and/or at least one enzyme.

Compositions are disclosed herein, for example, comprising oxidized insoluble alpha-glucan and a rubber component, wherein crystalline insoluble alpha-glucan is used to produce the oxidized insoluble alpha-glucan component(s). Additional compositions disclosed herein include those comprising oxidized insoluble alpha-glucan and a rubber component. Methods are further disclosed for preparing these compositions, as well as various applications of using them. Other compositions comprising oxidized crystalline insoluble alpha-glucan are also disclosed.

One or more embodiments of the invention are directed toward biodegradable films from distiller's dried grains with solubles (DDGS), especially sorghum DDGS, and methods of making the same. The films, which are suitable for use as packaging films, can be produced by directly conditioning the DDGS via a milling process, such as wet milling (e.g., colloid mill and ball milling) in water or a sodium hydroxide solution. The milled slurry is co-dissolved with plasticizers and stabilizers (preferably all less than 1% by weight) in a mixture of water and an organic solvent. The mixture is then used for film processing via pour-casting. The biodegradable films have significant antioxidant and antimicrobial activities related to their phenolic content.

A cellulosic particle contains cellulose as its base constituent, and the percentage water absorption of the cellulosic particle measured by method B in ISO 15512:1999 is 11% or more and 20% or less.

Our invention is a laminate film comprising a water-soluble resin layer and a polylactic acid-based resin layer laminated on at least one side of a substrate film, the water-soluble resin layer has a thickness of 0.1 to 15 m, the polylactic acid-based resin layer has a thickness of 10 to 500 nm. Such a configuration provides a laminate film of which the water-soluble resin layer and the polylactic acid-based resin layer are easily separated from the substrate film and which is excellent in coating ability, adherence and followability to a soft and curved adherend, as well as compatibility to skin and organs such as viscera, so as to be suitable for wound dressing, adhesion prevention material and a skin external agent such as skin-care product.

The present invention provides spherical monodispersed polyester resin particles and an aqueous dispersion thereof in an easy and inexpensive way, and a cosmetic product having fine extensibility, which has fine water resistance and smooth touch, and does not provide uncomfortable feeling to the skin.
