Embodiment 2

[0040] Example 2 was the same as Comparative Example 1 except that the heat seal temperature was 400°F.

Embodiment 3

[0042] Embodiment 3 is the same as Embodiment 2, except that the contact time of the sample heat sealing is three seconds.

Embodiment 8

[0056] Example 8 is the same as Example 2, except that in the adhesive composition, Mgraft-2 is used instead of Mgraft-1.

Abstract

A process for producing a multilayer structure is provided whereby an adhesive layer having a first side and a second side is contacted on its first side with a metal layer, having a first side and a second side, at a temperature of 325 DEG F to 425 DEG F for a contact time of 0.5 to 5.0 seconds, thereby adhering the adhesive layer to the metal layer. The adhesive layer comprises an ethylene- G4-8 alpha-olefin linear low density copolymer; a polymer grafted with an ethylenicaliy unsaturated carboxylic acid or acid derivative; and a styrene-butadiene-styrene triblock copolymer having an MI of 5 to 50.

Description

Area of invention [0001] The invention involves a method of forming a multi -layer structure with a metal layer.More specifically, the present invention involves a method of multi -layer structures with metal layers and SBS layers at low temperature and contact time. Invention background [0002] In the past ten years, the transportation, construction and storage industries have increasingly rely on composite materials to replace the construction design of wood or metal.However, due to the acceptance of composite materials, the application of all-metal structures in the semi-trailer, truck body and portable storage container has decreased, and aluminum, steel, and other metalsIt is still quite expensive because they provide durability and strength.These applications benefit from the metal layer to other layers of the structure in the metal layer as effective as possible.Similar interests exist in other applications, such as the nail-color tape, coils and cable belt products, and...
