Double-Sided PP Release Film: Versatile Protection for Precision Manufacturing

Introduction

Double-sided PP (polypropylene) release film is an engineered material designed to provide temporary surface protection and controlled adhesion on both sides.PP Silicone-coated Film Featuring release coatings on each surface, this film prevents unwanted sticking while enabling easy handling during processing. Its balanced release force, chemical resistance, and thermal stability make it ideal for composite manufacturing, PP Release Material Release Film electronic component protection, adhesive lamination, and other high-precision industrial applications where dual-sided protection is critical.

Key Features and Benefits

1. Dual-Sided Release Functionality

Both surfaces are coated with silicone or non-silicone release agents, allowing smooth separation from adhesives, prepregs, or molded parts.

Available in light, medium, or heavy release levels to match specific process requirements.

2. Excellent Chemical & Thermal Resistance

Withstands exposure to resins, solvents, and high temperatures (up to 180°C) without degradation, making it suitable for autoclave curing and hot pressing.

Pp Release Film for Medical industry Resists moisture absorption, ensuring stable performance in humid environments.

3. High Clarity & Low Haze

Optical-grade PP films provide clear visibility for alignment and inspection during layup or lamination processes.

Reduces defects in applications requiring visual quality control, such as display panel production.

4. Superior Mechanical Properties

Maintains puncture resistance and dimensional stability even under tension, preventing tearing during handling.

Flexible yet durable, allowing conformability to curved surfaces without wrinkling.

PP Release Film for Electronics Industry employs precision-extruded biaxially oriented polypropylene (BOPP) with laser-etched micro-patterned surfaces to achieve sub-micron release force control (0.5-5N/25mm) and <0.3% thermal dimensional change, ensuring precise component release in semiconductor die attach and micro-LED transfer processes, while PP Release Material Release Film integrates thermoplastic elastomer (TPE) composite layers and silicone-free adhesive systems to deliver 50-200% elongation at break with consistent peel force across -40°C to +150°C temperature extremes, making it ideal for flexible printed circuit (FPC) heat press lamination and automotive radar sensor housing encapsulation.
