In a world increasingly focused on sustainable packaging, businesses and consumers alike are turning their attention to alternatives that reduce environmental impact. One option gaining traction is water-activated tape (WAT), but is it truly eco-friendly?
What Is Water-Activated Tape?
Water-activated tape, also known as gummed tape or kraft paper tape, is a paper-based sealing solution that requires water to activate its adhesive. Once wet, it bonds securely to cardboard and other surfaces, creating a tamper-evident seal.
WAT is commonly made from kraft paper and a natural adhesive, such as starch. It’s often used in shipping by e-commerce businesses, warehouses, and retailers looking for a reliable and professional seal.
The Eco-Friendly Benefits of Water-Activated Tape
1. Made from Renewable Materials
WAT is typically composed of kraft paper, which is derived from wood pulp, a renewable resource. The adhesive is often made from plant-based starch, making the tape biodegradable and compostable in most forms.
2. Fully Recyclable
Unlike plastic-based tapes (like polypropylene or PVC), water-activated tape can be recycled right along with cardboard boxes. There’s no need to remove it before recycling, which increases the likelihood that the entire package will be properly processed.
3. Less Waste, Better Seals
Because WAT creates a strong, secure bond with fewer strips of tape, companies often use less tape overall. This reduction in material not only cuts costs but also minimizes waste.
4. Tamper-Evident
WAT bonds so tightly to boxes that it cannot be removed without visible damage to the packaging. This added layer of security can reduce returns and product loss, indirectly contributing to sustainability by lowering the environmental impact of additional shipping.
Are There Any Downsides?
While WAT is eco-friendly in many respects, there are a few considerations:
-
Dispenser Required: You need a water-activated tape dispenser, which can be an added cost and energy use in high-volume operations.
-
Not Always Waterproof: Though durable, WAT is less resistant to moisture than plastic tapes unless reinforced with water-resistant fibers (which may affect compostability).
-
Variants May Vary: Some reinforced versions contain fiberglass or synthetic fibers for strength, which are not biodegradable. Be sure to check the specifications of the tape you’re buying if compostability is your goal.
Final Verdict: Yes, But Check the Details
Water-activated tape is generally eco-friendly, especially when compared to plastic tapes. It’s made from renewable materials, is biodegradable, and enhances recyclability in packaging streams. However, to maximize its environmental benefits, opt for non-reinforced kraft WAT without synthetic fibers and ensure your disposal methods align with local composting or recycling standards.
If you’re looking to make your packaging more sustainable, water-activated tape is a strong step in the right direction.
