A variety of materials can be combined with lamination adhesive to create composite materials with unique properties to suit virtually any application. Whether you need tensile strength, cushioning, adhesion, fire resistance, shock absorption or thermal insulation or cold resistance, you can provide the best solution for your product.
Special laminating adhesive equipment uses pressure and heat to create permanent bonding between different products. The process is carried out by feeding two or more different rolls of material through a large roll under precise pressure and temperature conditions. In some cases, a material may be preliminarily applied with a carefully selected laminating adhesive that is brought into contact with other materials during the rolling process. In other cases, the adhesive may be uniformly sprayed or rolled onto the material because they are not suitable so that they are thoroughly coated before entering the rolling zone. The new composite material is wound at the end of the lamination process so that it can be cut to a specified length and width, or transported when used in a manufacturing facility. Regardless of the number of materials bound and how the adhesive is applied, the resulting material is permanently bonded and will combine the properties of each material used.
Any number of materials can be used to make composite materials with adhesive lamination. The most commonly used materials include polyurethane, polyurethane foam, polyethylene foam, silicone, low permeability foam for wet or harsh environments, closed cell PVC or rubber sponge or foam.
In terms of materials, flexible packaging may be one of the most complex applications. In addition to high image quality requirements and compliance with food safety regulations, multi-level consideration of material science also adds a lot of complexity. The flexible package consists of a multi-layer substrate in which one or more layers are printed and the adhesive holds all the layers together. If you have ever tried a package of chips or other food, you can only find that you have managed to pull out the ultra-thin package, and the package is still sealed, then you will recognize the laminated adhesive.
