Biaxial film orientation improves the overall strength, flexibility and toughness of plastic film. It is often used for packaging, so surface defects may adversely affect the freshness and environmental protection of a product.
While packaging is a common application, plastic film improved by biaxial orientation is also used for electrical insulation, solar power projects and a diverse range of scientific and technical operations. These frequently depend upon a high-quality film product.
The process involves molten plastic being extruded onto a roll, then quenched and drawn sequentially to introduce the required orientation. This orientation enhances the physical and optical qualities of the film in two directions. Because a thinner film is created by this process, it is prone to the introduction of surface defects or breaks.
Automated, accurate inspection can detect even the smallest defects in the film, identifying any flaws before applications are affected. This protects packaging and insulation from possible tears that may affect freshness and safety. In technical applications, it ensures performance is not compromised by imperfect film.
