The 3M 7000123639 is a transparent polypropylene box sealing tape designed for heavy-duty carton closure across a wide range of packaging applications. Sold in a case of 108 rolls, it uses a synthetic rubber adhesive on a polypropylene film backing that conforms around box edges and adheres firmly to rough or recycled fiberboard surfaces. The backing resists abrasion, moisture, chemicals, and scuffing, keeping sealed cartons intact through handling and transit. Packaging technicians and shipping operations staff commonly deploy this tape on both manual and high-speed automated dispensing lines.
This tape is suited for sealing heavy-weight and recycled fiberboard cartons in distribution, fulfillment, and warehouse environments. Its high edge-tear and split resistance make it a practical choice for ecommerce single-parcel shipments and bulk outbound freight. The easy-unwind construction reduces operator fatigue and maintains consistent dispensing speed on automated packaging equipment. It performs reliably on a wide range of corrugated and kraft surfaces, including those made with recycled content.
Designed for sealing heavy-weight corrugated and recycled fiberboard cartons in manual and automated packaging line applications.
Apply to clean, dry surfaces free of dust and loose fiber for best adhesion. Ensure adequate surface contact by pressing the tape firmly along edges and corners. On automated lines, verify dispenser tension and blade settings match the tape roll specifications before running production. Store unused rolls away from direct heat and humidity to maintain adhesive performance.
