What is Water-Activated Tape & Why it’s a Game Changer

Date: 10-11-2025 Posted in Product Education

As public opinion and environmental regulations shift, many Australian businesses are looking for ways to reduce plastic consumption. This is especially true for public-facing brands and e-commerce retailers who are keen to leverage packaging to reinforce a positive image while also satisfying practical requirements. In short, the ideal combination of aesthetics, eco-friendly credentials and effectiveness is the new standard for packaging solutions. 

Water-activated tape, also known as gummed tape, has become a popular choice for businesses seeking a strong, tamper-evident, and sustainable way to seal boxes. Made from natural kraft paper and a starch-based adhesive, this paper-based packaging tape delivers a professional finish while removing a whole lot of plastic from your operation’s overall usage.

How Does Water-Activated Tape Work? 

Water-activated packaging tape is made from 100% recyclable and renewable resources. It typically consists of two key components:

  • Kraft paper: With a pleasant and natural light brown colour, this durable outer layer provides a rigid surface you can print on. Sourced from FSC-certified forestries and fully recyclable.
  • Starch-based adhesive: A non-toxic, plant-based glue that becomes sticky when moistened with water. Poses no issues for recyclability or compostability. 

When activated, this adhesive fuses with cardboard fibres that make up boxes and cartons. Once dry, a secure seal that’s resistant to tampering, temperature changes, and other stresses is created. Unlike plastic tape, it doesn’t just stick on top, but bonds into the cardboard surface, forming one strong layer that’s tough to remove without leaving visible damage.

Why Businesses Are Making the Switch to Gummed Tape

From small businesses sending e-commerce parcels to industrial manufacturers sealing heavy cartons, more companies are moving to water-activated tape. Australia-wide business owners and their customers are increasingly interested in finding ways to reduce plastic consumption without compromising on performance, and water-activated packing tape is a perfect example of how to do this.

Gummed tape / water-activated tape provides a range of benefits:

1. Eco-Friendly and Sustainable 

Is water-activated tape eco-friendly? Made entirely from renewable resources, water-activated tape is recyclable. Since it’s crafted from paper and starch-based adhesive, there’s no need to remove the tape before recycling cardboard boxes.

This makes it the perfect alternative to conventional packaging tape for businesses looking to reduce plastic use, demonstrate care for the planet and cultivate a more ethical brand your customers (and our environment) will love. 

2. Tamper-Evident, Secure Seal

The activated tape bonds directly with the carton fibres, creating a stronger, more reliable closure than pressure-sensitive options. Once applied, it’s impossible to remove without visibly damaging the surface, creating a clear deterrent to help stop any tampering or theft during transport.

3. Professional Presentation 

The natural brown kraft finish of gummed tape gives packages a clean, professional look that complements sustainable brand identities. It’s ideal for businesses that value presentation and want to make their parcels stand out for the right reasons.

Types of Water-Activated Tape Available from Azapak

Azapak offers a focused range of water-activated paper tapes for different sized packages and levels of security. Every tape option is designed to provide consistent adhesion, durability, and sustainability, giving businesses confidence in every shipment.

Water-Activated Kraft Paper Tape

Standard Water-Activated Paper Tape

This environmentally friendly carton sealing tape is made from natural kraft paper with a plant-based starch adhesive. It provides a secure and tamper-evident seal, ideal for sensitive or valuable items. The adhesive bonds with the carton’s fibres to create a secure seal that can last longer than conventional plastic tape.

Suitable for use with both electronic water-activated paper tape machines and manual water-activated tape dispensers, it’s fully recyclable and biodegradable.

Water-Activated Kraft Paper Tape-Reinforced

Reinforced Water-Activated Paper Tape

For extra strength and reliability, Azapak’s reinforced water-activated paper tape includes cross-woven fibreglass strands. These fibres increase the tape’s tensile strength, making it ideal for shipping fragile or high-weight parcels.

Made from kraft paper, a starch-based adhesive, and fibreglass reinforcement, it provides a secure and tamper-proof bond while remaining recyclable. During the recycling process, the majority of the tape’s paper and adhesive components are recovered, while the minimal fibreglass strands are screened out.

How to Apply Water-Activated Tape

If you’re wondering how to use water activated packing tape, the process is simple once you’ve got the right tools.

Manual Application 

For small businesses or low-volume packing, a Manual Water-Activated Tape Dispenser is an easy and affordable option. The tape feeds across a wet roller that moistens and activates the starch adhesive as you pull and tear it to the desired length from the roll.

If you’re old enough to remember going to the post office to send a letter before the advent of peel and stick stamps (or even remember what a letter is), it’s quite similar to pressing the back of the stamp to the moist sponge before affixing it to the envelope. Similarly, once wet, the tape is ready to stick directly onto your cardboard box.

  • Suitable for both reinforced and non-reinforced tapes up to 70mm wide.
  • Perfect for manual applications or packing benches.
  • Provides consistent moisture activation and secure adhesion.

Water-Activated Tape FAQs

Yes. Water-activated tape forms a permanent bond with the carton’s fibres, creating a single, tamper-evident layer that’s far stronger than pressure-sensitive plastic tapes. The starch adhesive penetrates the cardboard surface, making it ideal for heavy, bulky or long-distance shipments. For even greater strength, reinforced gummed tape with fibreglass filaments delivers additional tear resistance.

Water-activated paper tape adheres best to corrugated cardboard and paperboard surfaces. It may not perform well on glossy, wax-coated, or highly laminated cartons, where the adhesive cannot bond effectively. For most standard e-commerce boxes and shipping cartons, however, it’s the perfect eco-friendly packaging tape choice.

Yes. Once the adhesive has fully dried, the seal remains stable in both cold and humid conditions. However, activation works best in moderate temperatures and humidity levels. In very cold environments, a slightly warmer activation water temperature can help improve adhesion. Once sealed, the bond won’t weaken even when exposed to refrigerated storage or damp transport conditions.
