Sealing Tape

Sealing Tape

Sealing tape is a single-sided, pressure-sensitive tape used mostly for closing or sealing slotted containers such as packing cartons and corrugated fiberboard boxes.  It is commonly used in warehousing industries for shipping and packaging needs.  Sealing tape is usually transparent or tan, and is often applied using a hand-held tape dispenser.  An adhesive is coated onto the backing material, which is usually made out of polypropylene or polyester film.  This type of tape is made to guard against score line breaking and center seam splitting, both common problems that happen when boxes are handled roughly.  Sealing tapes resist tearing, splitting, curling and moisture.

Sealing tapes are made with a variety of different coating types.  Acrylic adhesives provide high resistance to environmental elements, epoxy resins exhibit high strength and low shrinkage during curing, and polyurethane (PUR) has good flexibility, impact resistance and is durable.  Silicone has a high temperature resistance, and rubber-based adhesives create highly flexible bonds.  Sealing tapes are made with different peel and tensile strengths, temperature resistances and dielectric strengths.  They also come in different widths, thicknesses and lengths.  Although they are mostly used to close items such as cardboard boxes, sealing tapes bond with ceramics, glass, concrete, foam, leather, metal, plastic, paper, rubber, fabric and wood.
