Sealing heavy or high-value boxes with a tamper-evident seal that bonds into the cardboard fiber, impossible to open without leaving evidence, calls for a gummed tape that activates with water and forms a permanent bond in seconds. This kraft paper gummed tape —also called water-activated tape or water-activated tape (WAT)— is manufactured by Fortemo in fiber-reinforced kraft paper with an activatable starch adhesive, designed for fulfillment, export and operations that ship volume or delicate merchandise.
Key benefits
- Tamper-proof seal: when activated with water the adhesive penetrates the cardboard fiber and becomes part of the box; it cannot be peeled off without visibly tearing the surface, which reveals any opening.
- A single strip seals the box: the bond is so strong that one center pass seals the parcel, without the multi-turn H-pattern that plastic tape requires.
- Withstands weight and extreme conditions: it keeps the seal on heavy boxes and resists dust, cold and humidity where the contact adhesive of plastic tape gives way.
- 100% recyclable: paper and starch adhesive let you recycle the whole box without removing the tape, ideal for brands with an environmental commitment.
- Fiber-reinforced: the internal filaments raise tear resistance to unitize and export without the bond giving way in transit.
Applications and typical uses
- High-volume fulfillment and e-commerce that require fast single-pass sealing.
- Shipments of valuable or delicate merchandise where the tamper-evident seal protects against tampering.
- Export and unitization of heavy boxes that must withstand rough handling.
- Operations with an environmental policy seeking 100% recyclable, well-presented packaging.
Technical data
- Material: fiber-reinforced kraft paper, water-activatable starch adhesive.
- Widths: 48 mm (2 in) and 70 mm (2¾ in).
- Roll length: 100 m (110 yd).
- Activation: requires moistening with a gummed tape dispenser (manual or electric).
Quality and durability
A low-grade gummed tape fails because the glue activates unevenly —leaving unglued spots that lift— or the paper has no reinforcement and tears under tension. Fortemo works with fiber-reinforced kraft paper and a starch adhesive with uniform activation, the grade that sets an export tamper-evident seal apart from a tape that peels off at the first rough handling.
