Packed Material Company is a manufacturer of Reinforced Gummed Paper Tape for heavy carton sealing, export boxes, and industrial packaging lines where a standard paper seal is not enough. This reinforced water activated paper tape uses kraft paper backing, fiber yarn or fiberglass reinforcement, and water activated gummed adhesive that bonds into corrugated fibers after wetting. It is built for packed boxes that face lifting, stacking, conveyor movement, and long-distance handling, leaving visible fiber tear if the seal is opened.
Product Overview
Reinforced Gummed Paper Tape is made for corrugated cases that need more holding strength than ordinary paper sealing materials. The kraft paper backing works well with paper-based boxes, while the inner fiber yarn or fiberglass layer helps carry stress in both machine direction and cross direction. This is especially useful when a filled case is pulled from one side, pressed under stacked loads, or moved repeatedly across conveyors.
Packed Material Company produces this product with a dry gummed adhesive layer, so the roll stays clean and non-tacky before use. After controlled wetting through a dispenser, the adhesive becomes active and grips into the carton surface. When the seal dries, it normally tears the paper fiber instead of peeling away cleanly. That visible fiber damage helps make opened packages easier to notice during receiving, warehouse transfer, or export inspection.
Compared with pressure-sensitive carton sealing materials, this heavy duty gummed paper tape forms its hold through moisture activation, firm pressure, and paper fiber bonding, not surface tack alone. It is suitable for recycled corrugated cases, export boxes, and dense packed loads when the surface is not waxed, heavily coated, or covered with loose dust. For uncertain carton surfaces, a short sealing test before full packing is recommended.
Benefits
- Internal reinforcement improves tear resistance along the seam and across the tape width.
- Activated adhesive penetrates corrugated fibers for a firm, tamper-evident closure.
- MD/CD strength helps reduce seam splitting during lifting, stacking, or dragging.
- Works well as a kraft paper tape for export cartons, heavy boxes, and non-unitized shipments.
- Fits manual packing benches as well as higher-volume dispenser systems.
- Paper-based construction gives strong closure without depending only on plastic film tape.
What Makes the Reinforced Structure Suitable for Heavy Cartons?
Fiber yarn or fiberglass strands are laminated into the kraft paper structure, helping the material resist stress from different directions. In routine production sampling, typical MD tensile strength can reach 250-400 N/25mm, while CD tensile strength is commonly 90-260 N/25mm, depending on grade. For heavy cartons, this helps the sealed flap area stay firm during lifting, storage, or transport. The reinforcement also reduces edge tearing when boxes move through conveyors, pallet handling, or stacked warehouse rows.

Applications
- Heavy corrugated cases for industrial components, hardware, and spare parts.
- Export boxes that need stronger seam closure during long-distance movement.
- Recycled carton sealing where adhesive penetration and pressure improve hold.
- E-commerce bulk packages carrying dense goods or multiple packed items.
- Warehouse transfer boxes handled by conveyors, pallet movement, and manual lifting.
- Packages that require visible fiber tear if the sealed area is opened after drying.
How Does Water Activated Gummed Adhesive Improve Carton Sealing?
The adhesive is dry on the roll, which keeps the material clean before application. When the tape passes through a manual, electric, or automatic dispenser, water activates the gummed layer for bonding. Stable wetting, clean blades, and firm pressure help the adhesive flow into the paper fibers of the box surface. For a fiberglass reinforced kraft paper tape, the adhesive locks the seal to the corrugated surface, while the internal yarn structure helps resist tearing under load. This balance of wetting, pressure, and reinforcement is important for consistent sealing on heavy boxes.

FAQ
Is reinforced gummed paper tape only for heavy cartons?
No. It can also be used on medium cartons, but its main value is stronger sealing for heavy, export, or high-handling boxes.
Can this tape work with automatic machines?
Yes. It can run with suitable manual, electric, or automatic water activated tape dispensers. Wetting level, brush condition, and blade sharpness should be checked.
Does it seal recycled corrugated cartons?
Yes. It works on many recycled cartons. Testing is recommended for coated, waxed, very dusty, or low-fiber surfaces.
What is the difference from ordinary gummed paper tape?
Ordinary gummed paper tape mainly depends on paper backing and adhesive. Reinforced versions add fiber yarn or fiberglass strands for higher tear resistance and MD/CD strength.
