Preventing Refrigerator Panel Defects: Guangdayuan's PE Film Revolutionizes Injection Molding

Middle Eastern appliance makers face unique challenges with plastic panel quality in high-temperature factories. Guangdayuan's black-white PE film tackles sink marks and surface blemishes through precise stress compensation technology.
In Dubai factory trials, the 0.18mm film reduced sink marks from 18% to 2.3% in refrigerator door panels. The black layer's tight mold adherence and white layer's controlled 35% elongation create uniform counter-pressure during filling, resulting in denser plastic molecules. Post-molding gloss variation dropped from ΔE=2.8 to ΔE=0.9—a critical improvement for premium brands.
Heat resistance up to 170°C ensures no melting during 30-second mold contact, while low 0.07 friction coefficient cuts demolding time by 13%. A Riyadh-based manufacturer increased daily output by 15% after reducing cycle times from 52 to 45 seconds. Custom formulations for ABS and PC materials maintain optimal adhesion (50-60g/25mm), preventing coating damage during removal.#black-white PE film#
