What is Kraft Tape?
Kraft Tape, also known as gummed tape, is made from a kraft paper backing, a high-strength paper derived from chemically-treated wood pulp. The roll of kraft paper is coated on one side with a starch-based adhesive that requires water activation to become sticky. Kraft tape dispensers are equipped with sponges and/or moistening brushes that apply a thin layer of water to the tape to activate it. The kraft paper backing is durable and resistant to tearing, splitting, moisture, and common contaminants like dust and dirt. The water-activated adhesive is so strong that it penetrates the fibers of cardboard and paper packaging, creating a powerful and tamper-proof seal.
We have separate product guides for our Carton Sealing Tape and other Tape products:

What is Mil Thickness?
A mil is one-thousandth of an inch. Also known as a thou or a point, mil is the standard unit for measuring thickness in tape. As a point of reference, an average human hair is roughly 4 mil thick.
Kraft tapes are typically available in the 5-7 mil range, with 6 mil being the average.
