Perforated between labels for quick tear-off and fast workflow. Great for shipping labels, carton/warehouse inventory labels, and package identification

• DIRECT THERMAL = NO INK REQUIRED: Prints with heat—no ink, toner, or ribbons. High-grade thermal coating produces dark, crisp text and scannable barcodes for retail UPC, Amazon FBA FNSKU relabeling, inventory IDs, and general warehouse labeling. The labels are also water, oil, and scratch-resistant, keeping print clear, smudge-proof and fade-resistant even during transit, storage, and handling
• STRONG ADHESIVE THAT STAYS PUT: Reliable permanent adhesive bonds to common packaging like corrugated boxes, poly mailers, paper envelopes, and plastic bags. Labels lay flat without curling or falling off during transit, ensuring clean, professional labeling for e-commerce shipping, stockroom organization, and daily business use. Please note: This is a permanent adhesive label and cannot be repositioned once applied
• FAST TEAR-OFF, EASY PEEL DESIGN: Pre-perforated rolls help you label faster—tear a single label cleanly with no scissors. The easy-peel backing separates smoothly without tearing the label, making labeling fast and frustration-free even for high-volume workflows. Designed for Amazon sellers, Shopify stores, 3PL/warehouse pick-pack, retail backrooms, and office labeling
