In the electronics industry, light-sensitive components like semiconductors, LCD panels, and optical sensors demand strict light-blocking protection during packaging. However, light leakage in PE black-white film often compromises product quality—causing discoloration, functional degradation, or even complete failure. If your electronic components face similar issues, Shenzhen Guangdayuan Film Co., Ltd. offers a technologically advanced solution rooted in 20+ years of protective film expertise.
The Core Issue: Why Does Light Leakage Occur?
Light leakage typically stems from insufficient carbon black concentration, uneven coating, or improper thickness selection. Standard PE films may use recycled materials or low-grade pigments, leading to visible light transmittance exceeding 1%. Guangdayuan’s response? A three-layer co-extrusion system with 30%+ imported carbon black in the black layer, validated to achieve <0.1% light transmittance—verified by spectral analysis reports.
Guangdayuan’s Technical Edge
Tri-Layer Co-Extrusion Mastery: The proprietary structure combines a high-density black barrier layer, a shock-absorbing PE core, and a scratch-resistant white surface. This design not only blocks 99.9% of visible light but also enhances tensile strength by 40% compared to conventional films.
Custom Thickness Precision: Using automatic cutting tables with ±0.1mm accuracy, Guangdayuan offers 0.05-0.1mm thicknesses tailored for electronics. Thinner films (0.05mm) suit delicate circuit boards, while 0.1mm variants protect rugged components during heavy transportation.
Harbin Institute of Technology Collaboration: Nano-scale light-blocking additives developed through this partnership prevent pigment aggregation, ensuring uniform light absorption even after 1000+ bend cycles.
Industry Applications Beyond Electronics
While optimized for electronics, Guangdayuan’s PE black-white film excels in:
Optical Instruments: Protecting lenses and prisms from light-induced degradation in medical equipment.
Solar Panel Manufacturing: Shielding photovoltaic cells during lamination processes.
Automotive Electronics: Ensuring dashboard displays and sensors maintain clarity in direct sunlight.
Quality Assurance: ISO-Certified Reliability
Every batch undergoes 12 rigorous tests, including:
1、UV aging resistance (500-hour xenon lamp test)
2、High-low temperature cycling (-40℃ to 80℃)
3、Adhesion stability (3M tape pull test)Compliance with ISO 9001 and ISO 14001 guarantees consistent performance, while the water-based adhesive system eliminates harmful VOC emissions—ideal for green electronics manufacturing.
