Abstract

the case of certain applications in which heavy goods are to be packaged, however, the known packaging material can disadvantageously tear at certain points on account of the different high tensile stress between the film and the woven fabric. The invention relates to a packaging material comprising a pre-stretched and heat-stabilised elastic film (1) and an elastic plastic net arranged flat on the film, which is connected to the film (1) by means of an adhesive layer applied to the film (1), in such a way that a relative movement of the film (1) and the plastic net in relation to one another is permitted in the event of high tensile stresses. The adhesive layer is a water-soluble adhesive having a low adhesive strength.

Claims (9)

1. A packaging material, comprising an elastic film (1) and an elastic plastic net arranged flat on the elastic film, characterised in that the elastic film is pre-stretched and heat-stabilised and the elastic plastic net is connected to the elastic film (1) by means of an adhesive layer applied on the elastic film (1), wherein the adhesive is a water-soluble adhesive having a low adhesive strength, in such a way that a relative movement of the elastic film (1) and the elastic plastic net in relation to one another is permitted in the event of high tensile stresses.
2. The packaging material according to claim 1, characterised in that the elastic film (1) can be pre-stretched up to a thickness of 5 µm and has a residual elasticity of at least 20%.
3. The packaging material according to claim 1, characterised in that the packaging material has a width of 40 cm to 380 cm.
4. The packaging material according to claim 1, 2 or 3, characterised in that the elastic film (1) is produced from LLDPE, LDPE, HDPE, VC, EVA.
5. The packaging material according to claim 1, 2, 3 or 4, characterised in that the elastic plastic net is produced from LLDPE, LDPE, HDPE, PVC, EVA.
6. The packaging material according to claim 1, 2, 3, 4 or 5, characterised in that the elastic plastic net consists of fringes (3) extending in the flow direction of the net and weft threads (4), which connect the fringes (3) thereby forming a zigzag pattern to form a net, wherein the fringes (3) are each formed from a thread or wherein all or part of the fringes (3) are each formed from two or more threads to increase the strength of the fringes.
7. The packaging material according to claim 6, characterised in that the fringes (3) each comprise two or more partial fringes (3a, 3b) to increase the strength of the fringes, which are connected to one another by means of at least one weft thread (4) running in a zigzag manner, in such a way that the partial fringes (3a, 3b) run directly adjacent parallel to one another.
8. A method for producing packaging material executed according to any one of the preceding claims, characterised in that an elastic film (1) is pre-stretched to a defined, predetermined degree and then heat-stabilised, wherein an adhesive layer (2) is then applied on the elastic film (1), wherein the adhesive is a water-soluble adhesive having a low adhesive strength, wherein in a subsequent step the elastic film (1) and the elastic plastic net are pressed together by means of rollers, so that a packaging material arises, one side of which is constituted as an elastic film (1) which is self-adhesive and covered by an elastic plastic net without necking points, wherein a relative movement of the elastic film (1) and the elastic plastic net in relation to one another is permitted in the event of high tensile stresses.
9. The method according to claim 8, characterised in that the adhesive is applied by means of high-pressure jets or cylindrical axes.
