As demand grows for more sophisticated packaging and materials, the use of extrusion and lamination processes is more important than ever. The desire for strong barriers, sealability, and structurally strong packaging means a need for stronger adhesion within the thin multilayer composite structures being created.
Corona surface treatment is the ideal solution for just this need. Many materials used in extrusion and lamination are low surface energy materials, making it difficult to bond them together. This technology works by exposing the surface of these materials to a high voltage current, creating ionized air and increasing the surface energy, massively increasing the material’s adhesion properties. This allows materials to be better bonded together, improving product quality and durability.
Corona treatment can be used on a wide range of substrates used in extrusions and laminating, including plastics, metals, and other non-porous materials. It is commonly used in the production of a wide range of products, including food packaging, medical packaging, and industrial packaging. Examples of materials which can benefit from corona treatment include:
