Print Quality and Readability

Direct thermal labels succeed or fail on contrast and consistency. These Nelko labels are designed to produce:

• Dense blacks for high‑contrast barcodes and text
• Clean edges on small fonts and QR codes
• Reliable scanning for UPC/EAN, Code 128, Code 39, and QR within the 2″ x 1″ print area

Pairing them with the PL70E helps ensure precise registration and gap detection, minimizing misprints and waste. The protective topcoat resists smearing from light moisture and oils, keeping barcodes legible during routine handling.

Adhesion and Durability

The permanent adhesive is the star here—strong enough for corrugate boxes, poly mailers, plastic bins, retail shelving, and most smooth packaging films. It’s designed to be:

• Firm and long‑lasting once pressed down
• Resistant to common warehouse handling, light moisture, and incidental oil contact
• Less prone to corners lifting or curling

Tip: For highly textured surfaces or low‑surface‑energy plastics (like some HDPE containers), clean the area first and test one label to confirm bond strength.

Everyday Usability

• No ribbons or cartridges: Just load, calibrate, and print.
• Fast throughput: 1,000 labels per roll helps reduce changeovers in busy workflows.
• Easy to handle: The gap between labels aids consistent feeds and sensor accuracy.
• Compact size: Perfect for SKUs, price tags, small shipping stickers, and parts bins where 4″ x 6″ is overkill.

Setup and Compatibility Notes

• Printer: Optimized for the Nelko PL70E; not for the PM220.
• Loading: Seat the roll, route the web under the guides, and use your printer’s auto‑calibrate/gap sensor function (consult your PL70E manual for the exact steps).
• Settings: For maximum barcode density, use standard direct thermal settings first; only raise darkness if needed to avoid premature head wear.

If you run other printers, verify roll dimensions, core size, and sensor type (gap vs. black mark) before buying. While these labels are widely compatible with many direct thermal printers, always check the spec sheet.

Where These Labels Shine

• E‑commerce and retail: UPC labels, shelf tags, bin labels, price stickers
• Inventory control: SKU and location labels, asset IDs, reorder tags
• Small parcels: “Fragile,” return address/ID, or secondary shipping labels
• Office and backroom: File folders, cable/IT gear, sample jars, labelling drawers
• Light industrial: Parts trays, pick/pack stations, WIP labeling

Limitations to Know

• Direct thermal media can fade over time when exposed to heat, UV, or harsh chemicals. For long‑term outdoor use or archival labeling, consider thermal transfer labels.
• Permanent adhesives are not repositionable; plan placement before sticking.
• Not compatible with the PM220 Label Maker.

Best Practices for Crisp, Long‑Lasting Prints

• Storage: Keep rolls in a cool, dry place away from sunlight to prevent pre‑use darkening.
• Surface prep: Wipe dusty, oily, or wet surfaces before applying.
• Pressure: Use firm, even pressure—especially on corners and edges.
• Darkness setting: Use the lowest darkness that yields deep blacks for longer printhead life.
• Calibration: Run the printer’s auto‑calibration when switching sizes or brands to prevent misalignment.

Pros and Cons

Pros

• Sharp, high‑contrast barcode output with PL70E optimization
• Strong, reliable permanent adhesive
• Waterproof and oil‑proof topcoat for everyday durability
• BPA & BPS‑free materials

One roll delivers a lot of throughput without frequent swaps, and you avoid the ongoing expense of ribbons. For sellers and stockrooms standardizing on 2″ x 1″, this is an easy repeat buy.
