Heavy-Duty 3M PET for Industrial Label Substrates

Overview

The Heavy-Duty 3M PET is a premium polyester film designed for permanent labeling in the most demanding industrial environments. With a thickness of 25–50 microns, this material combines exceptional tear resistance, chemical tolerance, and dimensional stability, making it the standard for labels that must withstand extreme temperatures, harsh chemicals, and prolonged outdoor exposure. Its smooth, white surface ensures superior ink adhesion for thermal transfer, digital, and screen printing, enabling high-contrast graphics and text.

Features

Extreme Environment Resistance: Withstands temperatures from -40°C to +150°C and resists oils, solvents, and UV radiation, meeting UL 969 and CSA Z245.21 flame retardancy standards.

Permanent Adhesion System: High-tack acrylic adhesive forms a strong bond with metal, plastic, glass, and powder-coated surfaces, with optional low-tack variants for repositionable applications.

Printing Flexibility: Supports multi-technology printing—thermal transfer (resin ribbons), inkjet, and screen printing—for complex designs and variable data labeling.

Long-Life Performance: UV-stabilized coating prevents yellowing and color fade for over 5 years outdoors, maintaining label legibility in sun-exposed industrial settings.

Regulatory Compliance: Available with FDA-compliant adhesives for indirect food contact and FAA-approved variants for aerospace applications.

Application

Ideal for mission-critical labeling in harsh environments:

Automotive Manufacturing: Engine compartment labels, VIN plates, and safety warnings resistant to engine grease and vibration.

Electronics & Semiconductors: Circuit board labels, cable markers, and device serial numbers enduring soldering heat and cleaning solvents.

Heavy Equipment: Asset tags, maintenance schedules, and safety instructions for machinery operating in dusty, wet, or high-temperature conditions.

Aerospace & Defense: Component identification labels meeting MIL-STD-130 and Airbus specifications for aviation-grade durability.The material's rigidity and conformability make it suitable for flat, curved, and contoured surfaces, ensuring consistent performance across complex geometries.
