Problems solved by technology

In the lamination and roll forming techniques used in this field, films with no orientation or low orientation have large elongation and shrinkage at the temperature required for embossing, which makes laminated sheets made of continuous rolling. The product is more difficult

example 1

[0035] In this example, a 1 mil polyester carrier layer 50 and first layer 100 were provided in a combination of Tedlar SP, Typ 8 and laminated with a 4 mil embossing resin and a 2 mil Typ5 Tedlar layer.

[0036] a. Polyester web carrier, 1 mil;

[0037] b. 0.5 mil polyvinyl fluoride, non-oriented film solution cast on a web support (e.g. Typ8, Tedlar SP);

[0038] c. Printing layer (optional);

[0039] d.4 mil embossing resin;

[0040] e. 2 mil polyvinyl fluoride backing film, e.g. Type5 Tedlar;

[0041] f. Adhesive (optional) applied to the substrate, eg heat activated or pressure sensitive.

[0042] The laminate was produced by pre-coating 1-2 mils of embossing resin, followed by lamination to a printed Tedlar SP film layer and another layer of embossing resin to 1-2 mils, and laminated on Up to eg 2.0 mils on the back layer of Tedlar Typ5. The laminate was embossed through the Tedlar SP layer and the web carrier was attached in the embossing resin. The laminate can b...

example 2

[0044] A lightweight, dimensionally stable laminate made from Tedlar SP using a 2 mil thick embossed resin layer as the top layer and a formable 2 mil thick back layer.

[0045] a. Web carrier, such as 1 mil polyester;

[0046] b. 0.5 mil polyvinyl fluoride, non-oriented film solution cast on a web support (e.g. Type 8, Tedlar SP);

[0047] c. One or more print layers (optional);

[0048] d. Embossing resin, 2 mils;

[0049] e. Backing film, 2 mil, Type5 Tedlar;

[0050] f. Adhesive attached to the substrate (optional).

[0051] The laminate is produced by pre-coating, e.g., 1.0 mil embossing resin, followed by lamination on a printed Tedlar SP film layer and another embossing resin layer, and lamination on a back layer of Tedlar Type 5 to e.g. 2.0 mil. The laminate structure was embossed with a Tedlar SP layer and the web carrier was bonded in the embossing resin. The laminate may be coated with an adhesive applied to the substrate, the adhesive being heat activated or ...

example 3

[0053] A dimensionally stable laminate with a screen-printed pattern can also be textured in construction.

[0054] a. Web carrier;

[0055] b. 0.5 mil polyvinyl fluoride, non-oriented film solution cast on a web support (e.g. Type 8, Tedlar SP);

[0056] c. one or more printing layers, geometric or linear;

[0057] d. Embossing resin (eg 2.0 mil);

[0058] e. Embossing resin (eg 2.0 mil);

[0059] f. Backing film, such as Tedlar (2.0 mil);

[0060] g. Adhesive applied to the substrate (optional).

[0061] The laminate is produced by pre-coating 1-2 mils of embossing resin and then laminating the embossing by screen printing a geometric or linear imprint on Flower resin layer, and laminated on the back layer of Tedlar Type5, eg 2.0 mil. The laminate structure was embossed with Tedlar SP layers and the web carrier was bonded in embossing resin. The laminate may be coated with an adhesive applied to the substrate, the adhesive being heat activated or pressure sensitive. Th...

Abstract

A balanced dimensionally stable laminate uses a web carrier which is removably attached to a layer of the laminate during lamination and processing. The web carrier maintains dimensional stability of the layers of the laminate during lamination and processing and after removal of the web carrier. The web carrier is removed if at all only after the laminate is formed and processed. The bonding force of the web carrier with at least one of the polymers layer resists forces which would otherwise dimensionally distort the layers of the laminate or design features thereof during lamination, particularly in thermal roll-forming lamination. The layers of the laminate, which may include print and texture design features, remain dimensionally stable after removal of the web carrier. The web carrier can be removed at any time prior or after final application of the laminate to a substrate.

Description

technical field [0001] This application claims U.S. Provisional Application Serial No. 60 / 413,429, filed September 24, 2002, entitled "DECORATIVE LAMINATE WITH IMPROVED PROCESSING AND TEXTURE RETENTION PROPERTIES" priority. [0002] The present invention relates generally to laminate structures made from polymeric films; more particularly, to polymeric film laminates with decorative features including textured and imprinted patterns. Background technique [0003] Trim and structural panels for construction and transportation vehicles typically have a decorative laminate outer cover attached to a substrate. Decorative laminates are generally constructed with an outer surface of an aesthetic design feature of an embossed texture or imprinted pattern, or both. The decorative laminate is then formed and bonded to the underlying structural substrate layer. It is important to maintain the uniformity of the grain and printed pattern design features of the decorative laminate thr...
