Manufactured from 100 percent virgin brown kraft paper and coated with a bio-based starch adhesive. Designed specifically for light to medium industrial packaging, this water-activated tape offers a high-strength, plastic-free sealing solution for sustainable logistics.

Key Features

  • Tamper-Evident Security: The water-activated starch adhesive creates a molecular hydrogen bond with corrugated carton fibers upon hydration. Any removal attempt causes visible fiber tear, protecting shipments from theft.
  • Fiberglass Reinforcement: Embedded high-density fiberglass filaments deliver superior tensile strength, keeping cartons intact under dynamic shipping stresses.
  • Plastic-Free & Recyclable: Meets strict plastic reduction mandates in North America and the European Union. Recycles directly with cardboard boxes without requiring separation.
  • Efficiency Driven: Works seamlessly with automated carton sealers and manual water-activated tape dispensers, allowing operators to seal boxes securely with a single strip.

Industrial Applications

  • E-Commerce Fulfillment: Seals corrugated shipping boxes efficiently while meeting green packaging standards for online retailers.
  • High-Security Logistics: Protects sensitive shipments, electronics, and valuable goods from unauthorized access during transit.
  • Temperature-Controlled Shipping: Maintains a stable seal across ambient temperatures ranging from -10°C to 50°C.
  • Light Industrial Packaging: Bundles and secures materials safely using renewable, curbside recyclable materials.
