Sheet for producing plastic films and a process for producing this sheet |
摘要 |
This invention concerns a sheet for producing plastic films with a tear-resistant layer and a plastic layer that is applied to the former and has a surface that faces away from the tear-resistant layer and is suitable for applying liquid or pasty plastics for the plastic film to be produced. The surface of the layer of plastic which is preferably a negative of a relief pattern consists of polypropylene. The sheet permits a high fidelity in reproduction of the relief pattern plus a long lifetime as well. The sheet may be relatively thin, so a great length can be wound up on a roll. Therefore, great lengths of a plastic film can be produced in one piece by casting or spreading liquid plastic on the sheet. Therefore, the conversion time required for the manufacturing installation is short, which has a positive effect on the price of the product.
