Abstract

The plastic packing material consists of a sheet of plastic (1) in which cup-shaped depressions (2) have been formed, and a plain sheet of plastic (3) stuck across the cups. The result is a two ply sheet containing numerous pockets filled with air, and so able to act as heat insulators. A third sheet is added across the other side of the cups, thus trapping further air. The third sheet may be of aluminium or asbestos. The composite structure has flexible properties as a result of the thin sections of the intermediate members.

Description

Translated fromGerman

Mehrschichtige Isoliermatte oder dergleichen mit außenseitigerMulti-layer insulating mat or the like with an outside

Alu- oder Asbostschicht Es sind bekannt, Igoliermatten aus Glasfaser,Glasfaser mit Bitumen, Glasfaser mit Flles-, Bitumen-oder Alp-Schichten, es sindbekannt Isolierungen mit bedampftem Papier oder Folie oder Polyäthylen mit Gitterverstärkung.Aluminum or asbestos layer It is known that Igoliermatten made of glass fiber,Fiberglass with bitumen, fiberglass with flles, bitumen or alp layers, there areknown insulation with steamed paper or foil or polyethylene with grid reinforcement.

Seit einiger Zeit ist ein Verpackungsmaterial auf dem Markt, welchesmehrschichtig aus Kunststoffolie gefertigt ist und zlfar aus einer Unterfolie i)und einer Deckfolie 2). Aus dieser Deckfolie 2) sind in dichter Folge nebeneinanderNoppen herausgezogen oder gedrückt. Nun sind Unterfolie 1) und Deckfolie 2) luftdichtmiteinander verbunden. Die Hohlräume sind dadurch mit Luft gefüllt, so daß sie einefedernde oder polsternde Wirkung haben.A packaging material has been on the market for some time, whichis made of multiple layers of plastic film and consists of a lower film i)and a cover sheet 2). From this cover sheet 2) are side by side in close successionKnobs pulled out or pressed. The bottom film 1) and cover film 2) are now airtightconnected with each other. The cavities are thereby filled with air, so that they ahave a springy or cushioning effect.

Neuerungsgemäß ist die als Polster wirkende Folie Unterfolie 1) undDeckfolie 2) als Wärmeisolierung zu nehmen. Dazu kommt eine Alu- bzw. ähnliche Folie3) die durch Aufkleben oder Aufkaschieren 2) einen zusätzlichen Lufteinschluß, derdurch die Noppenbildung entstandenen Leerräume entsteht, bildet. Dies ergibt einezusätzliche Isolierung durch 3)1 außerdem wird durch Alufolie oder ähnliches 3)eine zusätzliche Wärmeabstrahlung gegeben.According to the innovation, the film acting as a cushion is the lower film 1) andTake cover sheet 2) as thermal insulation. There is also an aluminum or similar foil3) by gluing or laminating 2) an additional air pocket, theempty spaces created by the pimple formation are formed. This gives aadditional insulation through 3) 1 is also provided by aluminum foil or similar 3)given an additional heat radiation.
