Double-sided adhesive tape, method for sealing cartons or carton-like packaging and use of the adhesive tape in the method

摘要

The adhesive tape that is adhered on both sides comprises a carrier, which is equipped on both sides with an adhesive mass, where the adhesive mass is covered on one side with a covering material (31). A polyolefin foil is used as covering material with a breaking elongation of 200% and a tensile strength of 12 N/mm 2, where the covering material has breaking elongation of 5-times the breaking elongation of the carrier and/or the tensile strength of 1.5-times of the carrier. The carrier has a breaking elongation of highly 4% and a tensile strength of 15 N/mm 2.

A polyolefin foil is used as covering material with a breaking elongation of 200% and a tensile strength of 12 N/mm 2, where the covering material has breaking elongation of 5-times the breaking elongation of the carrier and/or the tensile strength of 1.5-times of the carrier. The carrier has a breaking elongation of highly 4% and a tensile strength of 15 N/mm 2, where the carrier has breaking elongation of highly 0.05-times of the covering material and/or the tensile strength of 0.6-times of the covering material. The carrier is a tea bag paper. The thickness of the liner (covering material) is 75-125 mu m. An independent claim is included for a method for sealing cardboard or cardboard-like packings.
