Basic Information:

• Definition: Water-activated kraft paper tape is a tape made from kraft paper and coated with water-soluble adhesive. The tape only becomes adhesive when water is applied to the back, and once activated, it provides strong adhesion. It is commonly used for sealing boxes and packaging where a high-strength, reliable bond is required.
• Material: The base material of the tape is kraft paper, which is naturally abrasion-resistant and tear-resistant, making it ideal for heavy-duty packaging and long-term storage. The tape’s adhesive layer consists of water-soluble adhesive, which is activated by water and forms a strong bond once applied.
• Appearance: Water-activated kraft paper tape is typically brown or light yellow in color, with a smooth surface that features the natural texture of kraft paper. The width and thickness of the tape can be customized to suit different packaging needs.

Chemical Properties:

• Water Activation: The tape’s water-soluble adhesive becomes active when it comes into contact with water. This activates the adhesive, allowing the tape to form a strong bond with surfaces like cardboard, wood, or plastic.
• Eco-Friendly: Kraft paper is a recyclable and natural material, making water-activated kraft paper tape an environmentally friendly packaging alternative to plastic tapes.
• Tensile and Tear Resistance: The natural fiber structure of kraft paper provides high tensile strength and tear resistance, allowing the tape to withstand heavy loads and friction during transportation.
• Tamper-Evident: Once applied, the tape cannot be reused, providing tamper-evident security. If someone attempts to remove or reseal the box, the tape will show visible signs of damage, increasing the security of the packaged goods.
