Layer Misalignment Exposing Color Lines at Cut Edges? Choose Guangdayuan‘s Precision-Coextruded PE Black and White Film

Product Characteristic

Edge misalignment between black and white layers during slitting — revealing an intermediate color line — is caused by poor thickness control of individual layers during coextrusion. Ordinary films have inconsistent layer distribution. Guangdayuan’s PE black and white film uses closed-loop layer thickness control with real-time X-ray monitoring. Developed with premium raw materials from Toray and Toyobo, each layer maintains precise proportional thickness, ensuring clean, aligned cut edges with zero exposed color lines.
