Streamline your product identification and industrial tracking with Mactape’s 3M™ 7871 Gloss White Polyester (PET) Labels. Engineered for extreme operational environments, 3M 7871 combines a 2.0 mil high-gloss white facestock with 3M’s premium 350 High-Strength Acrylic Adhesive.
Fully compliant with UL969 (File MH18072) and cUL safety standards, this durable label material provides permanent adhesion to textured plastics, powder-coated finishes, metals, and low surface energy (LSE) substrates. Designed for thermal transfer printing, it delivers ultra-sharp barcode readability, chemical resistance, and long-term durability across automotive, electronics, and heavy manufacturing sectors.
UL969 & cUL Certified (File MH18072): Fully compliant with North American and international safety standards for permanent marking and product labeling. Ideal for export-grade industrial machinery, automotive subassemblies, and consumer electronics.
High-Gloss PET Facestock (2.0 mil / 50 μm): The smooth white polyester topcoat optimizes thermal resin ribbon ink transfer. It delivers high-contrast, razor-sharp text, fine 1D/2D barcodes, and company logos with high scan rates.
3M™ 350 High-Strength Acrylic Adhesive: Formulated with a thick 1.8 mil (46 μm) adhesive coat. Provides exceptional initial tack and long-term bond strength on difficult-to-bond surfaces, including powder coatings, textured plastics, painted metal, and oily components.
Wide Thermal Tolerance (-40°C to +150°C): Maintains structural integrity and legibility under severe high-heat engine bays and freezing cold storage environments.
Chemical, Abrasion, & Tear Resistance: The heavy-duty polyester construction withstands motor oil, lubricants, mild acids, industrial solvents, and continuous mechanical rubbing.
Thermal Transfer Printable: Highly compatible with mainstream industrial barcode printers (Zebra, TSC, Honeywell, SATO) using resin or hybrid ribbons for on-demand variable data printing.

To ensure maximum print durability and barcode legibility on 3M 7871 labels, follow these operational best practices:
Ribbon Selection: Use full-resin ribbons for maximum chemical, heat, and scratch resistance. Wax-resin (hybrid) ribbons can be used for standard indoor applications.
Printer Darkness/Heat Settings: Set printer darkness to a medium-high level. Fine-tune to prevent toner smudging (too hot) or light print output (too cold).
Print Speed: Reduce print speed slightly when printing high-density 2D barcodes or micro-text to ensure crisp edge definition.
Printhead Maintenance: Clean the printhead regularly with isopropyl alcohol swabs to remove residual dust and adhesive build-up, extending printhead life and maintaining print quality.
Precision Die-Cutting: Available in rolls or sheets, custom die-cut into any shape or dimension to match automatic or manual labeling equipment.
Pre-Printing Options: Pre-print fixed branding elements (company logos, safety symbols, borders, static disclaimers) while leaving open areas for variable data thermal printing.
Custom Roll Cores: Choice of 1-inch or 3-inch roll cores with specialized liner scoring or back-printing.
Quality Assurance: Manufactured using 100% authentic 3M raw materials with full traceability, thickness testing, and adhesion verification.
