Water-activated tape (WAT) is also known as gummed tape. It is made of paper with reinforced crossing synthetic fibers for its strength and a water-based chemical adhesive that bonds to the surface of the box. Water-activated tape can be made of plain Kraft paper best suited for light cartons or it can include several layers of paper and fiber reinforcement for heavy parcels. When water is applied to the adhesive, a capillary action adheres the tape to the carton, creating a permanent bond.
Gummed tape is best used in conjunction with a water-activated tape dispenser which, in its most rudimentary form, wets and cuts the tape. More sophisticated dispensers automatically feed, moisten, and cut the tape to a pre-determined length. Packers then take the tape and apply it to the shipping carton.

Companies experience various benefits when they use water-activated tape to seal their cartons, including those listed below.
A single strip of gummed tape is enough to securely seal a carton. In comparison, packers using plastic, pressure-sensitive tape with a hand-held tape gun often use several strips of tape to secure the carton. This slows down the packaging process and reduces overall productivity.
Independent research has shown that using water-activated tape dispensers can improve productivity by as much as 21% over tape guns. Additionally, the repetitive and strenuous nature of using a tape gun to seal boxes can cause your employees to develop repetitive stress injury. If this occurs, your business can experience significant medical expenses and employee absenteeism.
Gummed tape creates a complete bond with the fibers of new or recycled corrugate providing a tamper-evident carton. Should someone try to remove the tape to gain access to the carton’s contents, the tape and the box will tear making it clearly apparent that it has been tampered with.
In the case of pressure-sensitive tape, the adhesive merely sits on top of the box. Thus, it’s easy to push down on the top of the carton. It creates an opening allowing someone to retrieve items and reseal the box with little to no evidence of what has happened. Here's an example of what this looks like.
Not only does water-activated tape provide a more secure bond for your shipping cartons, it also provides an opportunity to keep your brands top-of-mind. Rather than pay the high cost of pre-printing your logo on various sized shipping cartons, you can have your logo, or any message, printed directly on gummed tape. Printed water-activated tape creates a clean and professional look to your cartons.
If you compare the cost of WAT to pressure-sensitive tape on a per linear foot basis, water-activated tape often has a higher price tag. However, that is an incomplete analysis. Packers frequently usually use 2 to 3 strips of plastic tape to try to seal cartons versus the single strip of WAT used to secure the top and bottom of a box. When you include into the equation the volume of material employed, using water-activated tape becomes the more economical solution.
Factor in the higher productivity, the reduced risk of repetitive strain injury in employees, less theft and pilfering, and fewer damaged cartons, and it becomes crystal clear that water-activated tape makes great business sense.
