Gummed Paper Tape
70gsm GSI Brown Gummed Paper Tape (Water-Activated) — Reliable Carton Sealing
Gummed paper tape (also known as water-activated tape) is a proven way to seal cartons securely using a starch-based adhesive that bonds to corrugated board when moistened. This GSI brown gummed paper tape is a practical, everyday choice for packing benches and despatch areas that need a strong, tidy seal with a professional finish. Once applied correctly, the tape forms a fibre-to-fibre bond with the carton surface, helping to keep boxes closed through handling, stacking and transit.
Because it is paper-based, gummed tape is often chosen where a traditional “paper look” is preferred on parcels, or where teams want a sealing method that integrates well with paper and cardboard packaging workflows. It is also valued for its tamper-evident nature: attempts to remove the tape typically disturb the paper fibres and leave visible evidence on the carton.
Key Features
Water-activated adhesive bond:
Moisten the gummed side and apply to clean corrugated board to create a strong bond designed for carton sealing.
70gsm paper backing:
A robust paper weight suited to general packaging and despatch use, balancing strength with easy handling.
Brown paper finish:
A classic kraft appearance that looks neat on brown cartons and many recycled boards.
Tamper-evident seal:
Removal attempts are typically obvious because the tape bonds into the carton surface and can tear fibres.
Long roll length:
Supplied on extended-length rolls to reduce changeovers during busy packing runs.
Compatible with dispensers:
Designed for use with water-activated tape dispensers (manual or electronic) that wet and cut tape to length.

70gsm GSI Brown Gummed Paper Tape — Full Product Guide
Choosing the right carton sealing tape is about more than simply closing a box. The tape needs to suit your carton type, your packing speed, your storage conditions and the level of security you want in transit. This guide explains how gummed paper tape works, what to expect from a 70gsm paper backing, and how to get the best results in day-to-day use.
How It Works
Gummed paper tape uses a dry adhesive coating that becomes tacky when activated with water. Once the adhesive is moistened and the tape is pressed onto the carton, it bonds to the fibres of the corrugated board. This fibre bond is one of the reasons gummed tape is widely used for carton sealing: it is designed to hold well on cardboard surfaces and can provide a secure closure when applied correctly.
In practice, the process is straightforward:
- Wet the gummed side using a suitable dispenser or wetting method.
- Apply the tape centrally over the carton seam.
- Press down firmly to ensure full contact, especially along edges and over any carton texture.
For best performance, apply to cartons that are clean and dry (aside from the water used to activate the adhesive). Dust, loose fibres, heavy wax coatings or damp cartons can reduce adhesion.
Materials and Construction
This product is a brown paper gummed tape with a 70gsm paper backing. The paper backing provides the structure and tear resistance, while the gummed adhesive layer is activated by water. The brown finish is commonly used in packaging environments because it blends well with kraft cartons and many recycled boards, giving a consistent, professional appearance.
Paper gummed tape is often selected when teams want a paper-based sealing method that complements cardboard packaging. It can also be easier to write on than many plastic tapes, which can be useful for quick notes, batch markings or internal handling instructions (always test with your marker/pen for best results).
Carton and Board Compatibility
Gummed paper tape is primarily intended for corrugated cardboard cartons. It performs best when the carton surface is:
- Clean: free from dust, oils and loose debris
- Dry: not damp or wet from storage conditions
- Sound: not heavily crushed or delaminated along the seam
On very rough, highly recycled, or heavily textured boards, you may need to apply extra pressure to ensure the adhesive wets into the surface. If you are sealing cartons that are overfilled, bulging, or under high tension, consider whether a reinforced gummed tape is required for your application (reinforced options include fibreglass reinforcement; choose based on your packaging needs).
Health and Safety
Gummed tape is activated with water, so the main operational considerations are practical rather than hazardous. Keep the work area tidy to avoid slips from water drips, and ensure dispensers are maintained so they wet the tape evenly without excessive runoff. If using a dispenser with a cutting blade, follow standard safe handling procedures and keep hands clear of the cutting area.
As with all packaging materials, store rolls appropriately and keep them away from sources of moisture that could prematurely activate the adhesive.
Ideal Applications and Use Cases
This 70gsm brown gummed paper tape is well suited to everyday carton sealing where you want a dependable closure and a clean presentation. Common scenarios include:
- Despatch operations: sealing cartons for courier collection and palletisation
- Fulfilment and e-commerce: consistent sealing across a wide range of carton sizes
- Warehousing: sealing cartons for storage and internal transfers
- Manufacturing: closing cartons at end-of-line packing stations
Because gummed tape bonds to the carton fibres, it is often chosen where tamper evidence is desirable. If a parcel is opened and re-sealed, it is typically easier to spot compared with some plastic tapes that can sometimes be lifted and re-applied more cleanly.
Maintenance, Cleaning and Care
To keep your sealing process consistent:
- Store rolls in a dry place: humidity can affect paper and adhesive performance.
- Use clean water: in dispensers to help ensure even activation and reduce residue build-up.
- Maintain your dispenser: clean wetting brushes/rollers and check cutting mechanisms regularly.
- Apply firm pressure: especially at the start and end of each strip to prevent lifting.
If you notice poor adhesion, check carton condition first (dusty or damp board is a common cause), then confirm the tape is being adequately wetted and pressed down.
Case Study (Typical Packing Bench Improvement)
A common challenge in busy packing areas is balancing speed with consistency. Teams often find that switching to a water-activated tape workflow can help standardise sealing: operators dispense a measured length, apply it centrally, and press down once. With long roll lengths, changeovers can be reduced, and the finished parcels can look more uniform across shifts. The result is a sealing process that is easy to train and repeat, particularly when paired with a suitable dispenser.
As every operation is different, it’s worth trialling on your own cartons and through your typical handling route (bench to cage, cage to van, van to hub) to confirm performance.
