Water Activated Reinforced Gummed Tape

-- Steady & Reliable Manufacturer --

Product Overview

Water activated reinforced gummed tape consists of heavy-duty kraft paper backing laminated with multi-directional fiberglass filaments and coated with a starch-based adhesive. Upon water wetting, the vegetable adhesive penetrates paperboard fibers, forming a molecular bond with the corrugated box surface. This chemical bond creates a tamper-evident seal that cannot be removed without leaving visible paper tearing.

The embedded cross-hatched fiberglass grid distributes tension evenly across box seams, resisting bursting under internal load pressure and external stacking forces during transit.

Company Integration & Production Capacity

Zhejiang Geruite Packaging Materials Co., Ltd. operates integrated coating and slitting production lines in Zhejiang Province, specializing in industrial tape and packaging film manufacturing. Geruite’s facility produces water-activated kraft paper tapes, pressure-sensitive packaging tapes, PE stretch films, and plastic strapping for global logistics and manufacturing clients.

Each batch of reinforced kraft paper undergoes coat weight verification, water wetting response timing, and tensile strength testing prior to automated rewind packaging.

Application Fields

  • Ecommerce Carton Sealing: Tamper-evident sealing for high-value retail goods and parcel shipping boxes.
  • Heavy Industrial Shipping: Sealing double-wall and triple-wall corrugated containers up to 35kg gross weight.
  • Cold Storage & Export Logistics: Bonding securely on dusty, recycled, or unbleached corrugated fiberboard surfaces.
