Pro Pack Tape Company is a manufacturer of Water Activated Gummed Tape Jumbo for converting factories that need steady wetting response, clean slitting, and dependable box sealing strength. Made from 65-110 g/m2 kraft paper with water-activated starch adhesive, this master roll bonds into corrugated fiber after moistening and pressing. The result is a tamper evident carton seal with visible fiber tear, available in reinforced and non-reinforced structures for different sealing grades.
Product Overview
Water Activated Gummed Tape Jumbo is made for slitting and rewinding lines that convert large master rolls into finished carton sealing tape. The dry gum layer stays stable during storage and unwinding, then reacts when controlled moisture is applied through a water brush, sponge system, or electric dispenser.
For a water activated kraft tape jumbo roll, paper basis weight, adhesive coat weight, roll hardness, and coating uniformity all affect how the finished tape wets and seals. Non-reinforced grades commonly use about 20+/-2 g/m2 adhesive coat weight, while reinforced grades may use about 28+/-2 g/m2. Uneven coating can lead to slow activation, weak edge bonding, edge lift after drying, or inconsistent fiber tear.
After application, the softened starch adhesive enters carton surface fibers and dries into a paper-to-paper bond. On suitable corrugated board, removal should damage the box surface rather than peel away cleanly. Pro Pack Tape Company checks sample rolls for wetting response, coating transfer, slitting edge neatness, fiber tear, and +/-0.5 mm slitting tolerance before regular production. This supports gummed kraft paper tape jumbo production and reinforced gummed tape jumbo roll programs for heavier cartons.
Benefits
- Forms a fiber-bond seal after controlled wetting, not only a surface bond.
- Helps show opening marks through visible carton surface tearing.
- Uses starch adhesive instead of pressure-sensitive adhesive.
- Reinforced grades improve tear resistance for heavy cartons and export handling.
- Non-reinforced grades suit lighter cartons and simpler paper-based sealing.
- Consistent coating helps reduce weak wetting, edge lift, and uneven fiber tear.
When Should Reinforced or Non-Reinforced Jumbo Roll Be Selected?
Reinforced and non-reinforced structures should be selected according to carton load, handling route, and final sealing strength. Reinforced construction is normally better for stacking pressure, long-distance movement, heavy corrugated boxes, and valuable contents because the internal yarn improves tear resistance after bonding. Non-reinforced gummed tape is more suitable for light and medium cartons, palletized shipments, and packaging lines that prefer a simpler paper-based seal. For slitting operations, the choice also affects roll firmness, tension control, dispenser behavior, and finished tape unwind.

Applications
- Converting master rolls into finished carton sealing tape widths.
- Producing brown or white kraft sealing grades for different strength needs.
- Making tamper evident carton sealing tape for e-commerce and export cartons.
- Slitting reinforced grades for heavy corrugated boxes and high-stacking conditions.
- Supplying non-reinforced grades for light and medium box closure.
- Supporting printed tape programs where wetting response and fiber bonding remain required.
How Does Wet Activation Influence Carton Bonding Strength?
The wetting step controls how evenly the starch adhesive softens before the tape is pressed onto corrugated board. If the water level is too low, part of the dry gum layer may not fully activate. If too much water is applied, the paper backing can soften and affect placement accuracy. A well-made starch adhesive paper tape roll should give a balanced response within a practical open time, with max 13 sec used as a reference under controlled wetting. For production checks, moisture level, coating weight consistency, carton surface dust, edge lift, and fiber tear should be reviewed together instead of judging only by first tack.
FAQ
Q1: Is this jumbo roll supplied as finished small rolls?
No. It is mainly supplied as master roll material for slitting, rewinding, and finished roll conversion.
Q2: Can it bond to recycled corrugated cartons?
Yes, but recycled carton dust and fiber quality should be tested because they affect wetting and fiber tear.
Q3: Which grade is better for heavy cartons?
Reinforced grade is normally better because the internal yarn improves tear resistance after bonding.
Q4: Can the jumbo roll be produced in specified width?
Yes. Common jumbo widths are available, and specified width can be produced for converting requirements.
