Regular packing tape works on lightweight boxes. Put it on heavy cartons, and problems appear.
The tape stretches. Seams separate. Boxes arrive open.
Our reinforced water activated kraft tape solves this problem. Fiberglass strands run through the tape, giving it strength ordinary tape lacks. Combined with water activated adhesive that bonds to cardboard fibers, you get a seal that holds heavy loads.
Fiberglass Strands
Thin glass fibers run lengthwise through the kraft paper. These strands carry tension across the seal. When heavy contents push against the tape, the fibers hold.
Water Activated Adhesive
Starch-based glue penetrates cardboard fibers. As it dries, it becomes part of the box. No surface sticking. No peeling off.
Permanent Bond
Once dried, this tape does not come off without tearing the cardboard underneath. Tamper-evident by design.
High Tensile Strength
Kraft paper, fiberglass, and permanent adhesive combine to create a seal stronger than the box itself.
Heavy Industrial Shipments
Machinery parts, automotive components, bulk goods. Boxes over 15 kg need tape that handles the weight.
Export Containers
Boxes stacked in containers shift during transit. Seams take pressure from all sides. Reinforced tape holds when ordinary tape stretches and fails.
Warehouse Storage
Palletized boxes stacked high put constant pressure on bottom cartons. Reinforced tape maintains its seal under sustained weight.
Recycled Cardboard Boxes
Used boxes have worn fibers that don't hold adhesive well. Water activated adhesive bonds effectively to recycled material. Fiberglass provides extra security.
Automated Packing Lines
Works with water activated tape dispensers. Consistent moisture and tension ensure reliable seals at high volume.
| Feature | Reinforced Water Activated | Standard Water Activated | Plastic Packing Tape |
|---|---|---|---|
| Strength | Very high | High | Moderate |
| Holds Heavy Boxes | Yes | Some | Rarely |
| Bond Type | Fiber-bonded | Fiber-bonded | Surface |
| Tamper-Evident | Yes | Yes | No |
| Recyclable | Yes | Yes | No |
Reinforced tape sits at the top for strength. Standard water activated works for medium loads. Plastic tape lacks strength and security for heavy shipments.

Use a Dispenser
Manual or electric water activated tape dispensers ensure even moisture application. Wet tape evenly for best bond.
Apply Firm Pressure
Press tape firmly onto box seams after application. Helps adhesive penetrate cardboard fibers.
Allow Drying Time
Bond strengthens as water evaporates. Full strength reached in a few hours.
Store Properly
Keep rolls in original packaging. Protect from humidity. Use within one year.
Choose reinforced water activated kraft tape for:
Boxes weighing over 15 kg
Shipments stacked on pallets
Export containers with long transit
Recycled or worn cardboard boxes
Industrial and manufacturing shipping
Any application where box failure is costly
Consider standard water activated for:
Boxes under 10 kg
Office and retail shipping
Moving boxes
Standard e-commerce orders
Consider self adhesive for:
Lightweight shipments
Quick sealing needs
No water available
Manufacturing
Shipping assembled products, parts, components. Heavy boxes need secure sealing.
Automotive
Parts distribution centers ship heavy components. Reinforced tape ensures boxes arrive intact.
Food & Beverage
Bulk shipments of packaged goods. Palletized loads need tape that holds under weight.
Moving & Storage
Professional movers use reinforced tape for heavy boxes containing books, tools, household goods.
Select width – Wider tape gives more strength
Choose dispenser – Manual or automatic
Order tape – 150m, 250m, or 500m rolls
Train staff – Proper application matters
Test seals – Verify bonds before full use
How strong is it?
Standard grades hold over 40 kg on a 48mm strip. Much stronger than plastic or standard paper tape.
Can it hold boxes over 25 kg?
Yes. Use wider widths (72mm or 96mm) for maximum security on very heavy shipments.
Do I need special equipment?
A water activated tape dispenser gives best results. Hand application possible with wet sponge but less consistent.
How does it work on recycled boxes?
Very well. Water activated adhesive bonds to cardboard fibers regardless of whether they're new or recycled.
Is it tamper-evident?
Yes. Once dried, the tape cannot be removed without tearing the cardboard underneath.
Can I write on it?
Not easily. The reinforced surface is less receptive to pen or marker than standard kraft tape.
Is it recyclable?
Yes. The tape recycles with cardboard. Fiberglass strands are minimal and do not interfere with recycling.
What widths are available?
48mm, 60mm, 72mm, and 96mm are standard. Wider widths provide more holding strength.
How long does it take to dry?
Surface dry in seconds. Full bond strength develops in 2-4 hours depending on conditions.
Can I use it in cold warehouses?
Yes. Water activated tape bonds effectively down to 0°C. Application best at room temperature.
Reinforced water activated kraft tape delivers the strength heavy boxes need. Fiberglass strands carry tension across seams. Water activated adhesive bonds permanently to cardboard fibers.
For industrial shipping, export containers, or any application where box failure is not an option, reinforced tape is the reliable choice.
