NIIMBOT 50×30 mm Thermal Label Rolls 3-Pack (230 Labels/Roll) White — Direct Thermal, Waterproof

NIIMBOT 50×30 mm thermal label paper comes as three white rolls (230 labels per roll) that print without ink and stick firmly to many surfaces. These thermal label rolls are engineered for NIIMBOT label makers (compatible with B1, B21, B31, B3S and K3 models) and deliver crisp, fade-resistant text and barcodes using direct thermal technology. Each 50×30 mm label is waterproof, oil-resistant, and tear-resistant while remaining non-toxic and degradable, so you get durable labels without ribbons or ink cartridges. The package includes an Intelligent Identification chip that allows supported NIIMBOT printers—especially the B21—to detect the tape automatically, saving set-up time.

How will these labels improve my daily labeling tasks?

These thermal rolls remove the need for ink or ribbon, simplifying printing and lowering ongoing costs. Labels print clearly and resist smudging, which keeps barcodes and descriptions readable in busy environments.

• Direct thermal printing — clean output without consumable inks.
• High adhesiveness — stays put on cardboard, plastics, glass and more.
• Water and oil resistance — suitable for kitchens and warehouses.
• 230 pre-cut labels per roll — fewer roll changes during tasks.

Will these rolls work with my NIIMBOT printer model?

The rolls are made specifically to fit NIIMBOT B1, B21, B31, B3S and K3 label makers. The included Intelligent Identification chip ensures the B21 and other compatible printers recognize the roll automatically so you don’t have to choose templates or adjust settings manually.

• Compatible models: B1, B21, B31, B3S, K3.
• Auto-detection chip for quick setup on supported units.
• Standard 50×30 mm label size fits common template options.

What kinds of surfaces and environments do these labels hold up to?

The adhesive is formulated to grip a wide range of materials — from corrugated boxes to smooth glass — while the thermal face resists fading from water and oils. That makes these rolls practical for shipping, storage, retail tagging and household organization.

• Works on kraft paper, plastics, PVC, wood, glass and metal.
• Resistant to water, oil and abrasion to maintain legibility.
• Tear-resistant material for handling and transport durability.

How eco-friendly and safe are these thermal labels?

The label stock is non-toxic and designed to be degradable, and printing requires no ink or ribbon waste. These aspects reduce consumable disposal compared with some other labeling systems, while still delivering long-lasting results.

• Direct thermal printing eliminates ink and ribbon cartridges.
• Non-toxic material suitable for general-use environments.
• Degradable paper composition reduces long-term waste.

These three-roll packs are ideal for small businesses, home offices, e‑commerce sellers, and anyone using a compatible NIIMBOT label maker who needs reliable, high-adhesion labels in a standard 50×30 mm size. Whether you’re printing address labels, barcode tags, pantry organization stickers, or product identifiers, this pack delivers consistent, legible output and fewer interruptions for roll changes.
