| 摘要 |
<p>The present invention relates to a composite material comprising a composite film for the production of a tubular bag (7) according to a form-fill-seal method, or made of a cardboard composite. The present invention provides a composite material that may be reshaped by means of thermal radiation or ultrasonic application, and which after respective application assumes a sufficiently dimensionally stable, three-dimensional state such that packages or other articles can be produced in the desired shape. In this regard the present invention provides a composite material consisting of a composite film (1), or of a cardboard composite, comprising a first layer (2), a material (3) sensitive to radiation, and a second layer (4) connected to the first layer (2) by means of a heat sensitive laminating adhesive which is provided in a region of the material (3) sensitive to radiation, and/or in a region that is recessed by the material (3) sensitive to radiation, and forms an increased adhesive effect upon the supply of heat by means of thermal radiation or ultrasonic application.</p> |
