Biaxially oriented polypropylene (BOPP)
When polypropylene film is extruded and stretched in both the machine direction and across machine direction it is called biaxially oriented polypropylene. Biaxial orientation increases strength and clarity.BOPP is widely used as a packaging material for packaging products such as snack foods, fresh produce and confectionery. It is easy to coat, print and laminate to give the required appearance and properties for use as a packaging material. This process is normally calledconverting. It is normally produced in large rolls which are slit on slitting machines into smaller rolls for use on packaging machines
1.Product description
1. Enhance the finished presswork's alue through high transparent and super finish. Prevent lamiation from being pressed bubbled and desquamate. Protect from harmful substances and water-proof,making long life storage for the printings.
2. Available in various paper and inks,and suitable for lamination even with powder paper. After be treated with corona on the surface,It is good for spot UV and hot stamping.
3. Excellent cost saving because the works of adhesive mixing,coating and drying are all not needed.The poeration doesn't require special technique and the film can be used in dry and wet laminator.
4. Environmental friendly and non-hazardous to health and safe because there is not any toxic gases or volatile content emitting during production and use.
Feature
BOPP thermal laminating films are lamination films having BOPP (biaxially oriented polypropylene) as base material. We use extrusion coating process to combine layers of BOPP film and thermal laminating adhesive(EVA). In the final film one side have properties of BOPP film and the other one becomes heat sensitive surface used for dry lamination.
BOPP Thermal Laminating Films are more economical over laminate with excellent clarity and brightness. Polypropylene has high acid resistance and good folding characteristics. It is Ideal for Write-on/Wipe-off applications.
