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.
