FIELD: packaging industry.SUBSTANCE: present invention relates to a device for packaging, particularly of food products or industrial materials. Object of the invention is to create a device with the ability to provide a simple and rapid manual packaging of products. The device for packaging is stated, in particular, for manual or automatic packaging of food products or industrial materials which can be placed through the loading surface that can move transversely between the longitudinal folded parts of the film with one fold from its open side. The device comprises a thermally bonded or heat-sealable means for sealing and at least one nozzle for creation of vacuum and/or introducing gas or a mixture. The nozzle is made with the ability of extending/shortening, when the change of the width of the film by one bending, and is used for tension and/or direction of the said film with one bend at its transverse movement. The gas or the mixture is additionally injected proximate to the first folded longitudinal side of the said film with one bend.EFFECT: creation of a structurally simple device that is reliable and safe to use.11 cl, 10 dwg |
