Gummed Paper Tape
36mm x 200m (60gsm) GSI Brown Gummed Paper Tape — Overview
This listing is for a brown water-activated (gummed) kraft paper tape supplied in roll form. It is commonly used for sealing cartons and parcels where a strong, tamper-evident paper seal is preferred. The tape is identified as GSI (Gum Side In), meaning the adhesive (gum) layer is on the inside of the roll.
Gummed paper tape is designed to be activated with water (by hand with a sponge/brush or with a dispenser). Once activated and applied, it bonds to corrugated cardboard to create a secure seal that is difficult to remove without visible damage to the carton surface.
Key Features
Water-activated adhesive (gummed):
Apply water to activate the gum, then press firmly onto clean corrugated board for a strong carton seal.
Paper-based kraft tape (brown):
A traditional kraft paper appearance that suits many packing environments and blends well with brown cartons.
GSI (Gum Side In) winding:
The gum layer is wound on the inside of the roll. This is a common format for water-activated tape systems—always check your dispenser requirements before ordering.
60gsm paper weight:
A lightweight kraft paper tape option intended for general carton sealing tasks where a paper tape is preferred.
Long roll length:
Supplied on a long roll format to reduce changeovers compared with shorter rolls (exact roll length varies by variant selection on this page).

GSI Brown Gummed Paper Tape — Full Product Guide
Water-activated gummed paper tape is a proven carton-sealing solution used across warehousing, e-commerce fulfilment, manufacturing dispatch, and general packing operations. Unlike pressure-sensitive plastic tapes, gummed paper tape uses a starch-based adhesive that is activated by water. When applied correctly, it bonds with the carton surface to create a secure seal that is difficult to remove cleanly.
This product is specified as 36mm wide and supplied on a 200m roll with a 60gsm kraft paper backing, and it is wound GSI (Gum Side In). Because Sapphire product pages can represent multiple pack quantities/variants, please select the option that matches your required pack size and workflow.
How It Works
1) Activate: The adhesive is dry on the roll. Apply a thin, even film of water to the gummed side using a dispenser, brush, or sponge.
2) Apply: Place the activated tape onto the carton seam and press down firmly, especially along edges and over any corrugation ridges.
3) Bond: As the adhesive sets, it forms a strong bond with the carton surface. This creates a paper-to-paper style seal that is typically more resistant to lifting than many standard pressure-sensitive tapes when used on suitable cartons.
Tip: Use only enough water to activate the gum. Over-wetting can reduce initial tack and may cause curling or wrinkling during application.
Materials and Construction
Kraft paper backing: The tape uses a brown kraft paper carrier. The stated 60gsm paper weight indicates a lightweight paper backing suitable for general sealing tasks.
Gummed adhesive layer: The adhesive is a water-activated gum that remains non-tacky until moistened. This helps keep rolls clean in storage and reduces the chance of adhesive contamination before use.
GSI winding: “Gum Side In” means the adhesive faces inward on the roll. This matters for compatibility with dispensers and for how the tape feeds during activation.
Carton / Surface Compatibility
Gummed paper tape is primarily intended for corrugated cardboard cartons. For best results:
- Apply to clean, dry, dust-free carton surfaces (before activation).
- Ensure cartons are not heavily coated with wax, silicone, or release coatings that can inhibit bonding.
- Press firmly along the full tape width to ensure good contact with the carton fibres.
If you are sealing recycled cartons with high dust content or very rough surfaces, test a small run first to confirm performance in your environment.
Health and Safety
- Use standard safe-cutting practices when opening cartons or cutting tape (dispensers with guarded blades are recommended where possible).
- Keep water reservoirs in dispensers clean and change water regularly to maintain consistent activation.
- Store rolls in a dry area to prevent premature moisture exposure.
Ideal Applications and Use Cases
This tape format is commonly chosen for:
- General carton sealing: Everyday sealing of shipping cartons in warehouses and dispatch areas.
- Tamper evidence: A paper seal that typically shows visible disturbance if removed.
- Process consistency: Packing benches using water-activated dispensers for repeatable application.
- Paper-based packaging preference: Where a kraft-paper tape appearance is desired on brown cartons.
Maintenance, Cleaning and Care
Roll storage: Keep rolls sealed in their packaging until use and store away from humidity.
Dispenser care: If using a water-activated tape dispenser, clean the wetting brush/roller periodically and remove any adhesive build-up. Replace worn brushes/rollers to maintain even wetting.
Application checks: If you notice lifting edges, check for insufficient water, dusty cartons, or inadequate pressure during application.
Case Study (Typical Packing Bench Scenario)
A small dispatch team sealing cartons by hand may switch to water-activated gummed paper tape to improve seal consistency and reduce re-taping caused by edge lift on dusty cartons. By using a simple manual or electronic dispenser, the operator can wet and cut consistent lengths quickly, apply them centrally over the seam, and achieve a neat paper finish on each carton. Results depend on carton quality, surface condition, and correct activation, so a short trial is recommended before full rollout.
