Performance Characteristics

High Thermal Tolerance:

Withstands operational temperatures up to +150°C without shrinkage or edge lifting.

Chemical & Solvent Resistance:

Resists exposure to motor oils, industrial solvents, mild acids, and cleaning chemicals.

Mechanical Durability:

High tear strength and abrasion resistance preserve barcode scannability throughout product lifecycles.

Material Formats

Clear PET: High-clarity film engineered for transparent packaging and subtle branding integrations.

White PET: High-opacity film ensuring maximum contrast for high-density barcodes and regulatory text.

Metallized PET: Vacuum-deposited aluminum layer delivering a bright metallic finish with full barrier protection.

Adhesive Systems

Permanent Acrylic:

Standard formulation providing high initial tack and long-term bond to steel, aluminum, and polar plastics.

Removable Acrylic:

Specially engineered to peel clean without leaving residue or adhesive transfer on smooth surfaces.

High-Tack Formulations:

Developed specifically for low-surface-energy (LSE) materials, including textured polyolefins and powder-coated metals.

Key Applications of PET Film Labels

01/

Electronics & Appliances: Used for rating plates, serial number labels, and printed circuit board tracking.

02/

Industrial Machinery: Machinery asset tags, safety warnings, and heavy-equipment identification plates.

03/

Chemical Containers: GHS hazard identification labels resistant to aggressive liquid spills and UV weathering.

04/

Automotive Components: Engine compartment decals and interior component manufacturing labels.

Precision Converting & Finishing

Custom Rotary Die-Cutting: Precision die-cutting supports custom roll shapes with tight dimensional tolerances.

Surface Treatments: Corona treatments improve ink adhesion for UV-curable inks and thermal transfer ribbons.

Varnishing & Lamination: Over-lamination options provide extra barrier protection against continuous abrasion.

Quality Assurance

Raw Material Inspection: Spectrophotometers and digital micrometers verify facestock gauge, surface tension, and liner consistency.

In-Line Print & Code Inspection: Automated optical inspection (AOI) monitors color accuracy, registration, and 1D/2D barcode grades.

Finished Roll Validation: Roll tension control, edge trim precision, and liner release force are tested before shipment.

Quotation Checklist

To receive a complete technical quotation, specify:

• Target substrate material and surface texture (e.g., metal, LSE plastic, glass)

• Expected service temperature range and chemical exposure

• Label dimensions, layout shape, and artwork file specifications

Manufacturing Capacity

Production facilities equipped with high-speed coating, multi-color printing, and precision slitting machinery yield an annual capacity of 2.2 billion labels. Standardized quality procedures ensure batch-to-batch repeatability across high-volume orders.

FAQ

Q: What is the standard continuous temperature limit for PET labels?

A: PET labels operate continuously between -40°C and +150°C without dimensional deformation or adhesive breakdown.

Q: Can PET labels be applied to low-surface-energy plastics?

A: Yes, using high-tack modified acrylic adhesives specifically formulated for untreated polypropylene and powder-coated surfaces.

Q: Which ribbon type provides the best print permanence on PET labels?

A: Full resin ribbons provide optimal thermal transfer printing performance, offering superior resistance to solvents and mechanical rubbing.

Q: How are PET labels supplied for automated labeling systems?

A: Labels are supplied on standardized 76mm (3-inch) cores with customized unwind directions and precise matrix stripping for automatic applicators.

Q: What documentation is provided for international shipping?

A: Shipments can be accompanied by Certificates of Analysis (COA), Technical Data Sheets (TDS), and material safety compliance records upon request.
