Abstract: FIELD: food industry. 
     SUBSTANCE: invention relates to food industry, in particular, to devices for packing extracted products, their brewing and consumption. Disposable label-envelope for packaging, storage, brewing and consumption of tea, coffee, cocoa and other beverages, containing a moisture-permeable sachet with a measured portion of the extractable substance, an elastic plate with a formed fold and bent in halves in the transverse direction, with arrangement on the plate of information on the extractable substance, wherein in place of formed plate bend through cutout is made, shape and size of which are comparable to diameter of handle or baking dish cover, and in the center of the fold or on the side of the plate there is a cut ending in the through cutout, in addition, the ends of the plate are interconnected to form a closed chamber cavity by the plate itself, used to accommodate a moisture-permeable sachet with a proportioned portion of the extractable substance, note here that at attachment point of plate ends on one of edges there is fastening thread attaching plate with moisture permeable sachet with proportioned portion of extracted substance. Resilient plate can be made of polymer material, from dense cellulose material from laminated cellulose-paper material or from hydrophobic material. Ends of the bent plate can be cross-linked by a thread which simultaneously connects the plate to the moisture-permeable sachet with the proportioned portion of the extractable substance; can be glued, wherein the suture connecting the moisture-permeable sachet with the proportioned portion of the extractable substance with the plate is glued to the junction point; can be connected by means of thermal welding, wherein the suture connecting the moisture-permeable sachet with the portion of the extracted substance is welded in to the joint; can be connected by means of ultrasound, wherein the thread connecting the moisture-permeable sachet with the portion of the extractable substance is mounted into the connection point; can be connected with bent plate by means of bracket; can be connected to plate by means of gluing by means of paper gluing. At that, the thread connecting the ends of the bent plate with the moisture-permeable sachet with the proportioned portion of the extracted substance, with its one end can suture the plate, and with its other end sutures the moisture-permeable sachet, note here that said thread can be made of several threads and can be made of hydrophobic material. Envelope label with a moisture-permeable sachet with a measured portion of the extractable substance placed in it is placed in a packing bag. 
     EFFECT: technical result consists in creating a label in the form of an envelope, which by its design enables simultaneous storage of a package with an extractable product, transportation thereof, release without direct contact of consumer with consumed product and fastening of label-envelope to baking dish with providing on one side convenience of consumption, and on other side – absence of drop formation on plate.
