Abstract
The present invention relates to a method for producing a single-sided adhesive film (1) for securing a load, comprising providing a backing layer (2) and coating a first side of the backing layer (2) with an adhesive layer (3), wherein a plastic (4) is applied to a second side of the backing layer (2) in order to form a non-slip surface on the adhesive film (1). Moreover, the present invention relates to a single-sided adhesive film (1) produced by the above method.
Claims3
A method for producing a single-sided adhesive film for securing a load, comprising:
- providing a backing layer;
- and
- coating a first side of the backing layer with an adhesive layer,
- wherein a plastic is applied to a second side of the backing layer in order to form a non-slip surface on the adhesive film, and
- wherein the backing layer is provided in the form of a polyester film,
- characterized in that prior to bonding to the adhesive layer and the plastic, the polyester film is treated with trichloroacetic acid, sodium persulfate, iron chloride or copper chloride in order to increase the surface energy of the polyester film,
- wherein the plastic comprises polyurethane and is directly sprayed onto the second side of the backing layer so that the non-slip surface is planar.
