The are two types of carton sealing tape,
pressure sensitive and water activated. Polypropylene and PVC are the most
popular pressure sensitive tapes manufactured with acrylic, hot melt or
natural rubber adhesives. Water activated tapes are constructed of Kraft paper
and can include fiberglass reinforced strands embedded in the Kraft paper
Pressure Sensitive Tapes:
Can be applied using automatic carton closing machinery or inexpensive
pistol grip dispensers. The following are the three main adhesives use for
carton sealing tape: NATURAL RUBBER; Is the best and most expensive
packaging tape. Natural rubber tapes provide superior adhesion in extreme
temperatures (0-150 degrees). Natural rubber is not affected by humidity
or dampness. Natural rubber yellows with age and is darker in color than other
pressure sensitive tapes. ACRYLIC; Will not yellow with age
and has excellent clarity. Acrylic adhesive tapes can be applied in
temperatures ranging from 32 - 140 degrees. An excellent general purpose
packaging tape. HOT MELT;
(synthetic rubber) Is normally manufactured with a polypropylene backing and
is the lowest cost packaging tapes available. Hot melt tapes work well
in 45 - 120 degrees and provides a good bond to most corrugated cartons.
Will yellow with age but not as quickly as natural rubber based
Activated Tapes: The first carton sealing tape. The gummed
adhesive must be applied using a dispenser containing water to activate the
adhesive. Gummed Kraft paper tapes form a super bond to corrugated that
will not fail. Gummed paper tapes are unaffected by heat or cold.
Water activated tapes are recyclable.
Abrasion Resistance: The ability
of a tape to withstand rubbing and still functions satisfactorily.
A transparent film used as a tape backing. More moisture resistant
polymer with excellent aging characteristics that can be used as either a
single component adhesive or saturant, depending upon composition.
A bond produced between a pressure sensitive adhesive and a surface.
Deposit/Residue: Adhesive that is pulled away from the tape and remains on
the surface to which the tape is applied
