History :
Pressure-sensitive adhesive, a key component of some adhesive tapes, was first developed in 1845 by Dr. Horace Day, a surgeon. In 1901, the German Oscar Troplowitz invented an adhesive patch called Leukoplast for the German company Beiersdorf AG. In 1936, German company Beiersdorf AG invented a transparent adhesive patch called Tesa.
Water activated tape
Water activated tape, gummed paper tape or gummed tape is starch- or sometimes animal glue-based adhesive on a kraft paper backing which becomes sticky when moistened.
A
specific type of gummed tape is called reinforced gummed tape (RGT).
The backing of this reinforced tape consists of two layers of paper with
a cross-pattern of fiberglass filaments laminated between. The
laminating adhesive had previously been asphalt but now is more commonly
a hot-melt atactic polypropylene.
Gummed
tapes are described in ASTM D5749-01(2006) Standard Specification for
Reinforced and Plain gummed Tape for Sealing and Securing.
Water-activated
tape is used for closing and sealing boxes. Before closing corrugated
fiberboard boxes, the tape is wetted or remoistened, activated by
water.
WOODEN PALLET
A pallet is a flat transport structure, which supports goods in a stable fashion while being lifted by a forklift, a pallet jack, a front loader, a jacking device, or a crane; sometimes, a pallet is inaccurately called a skid (which has no bottom deck boards). A pallet is the structural foundation of a unit load which allows handling and storage efficiencies. Goods or shipping containers are often placed on a pallet secured with strapping, stretch wrap or shrink wrap and shipped. Since its invention in the twentieth century, its use has dramatically supplanted older forms of crating like the wooden box and the wooden barrel, as it works well with modern packaging like corrugated boxes and intermodal containers commonly used for bulk shipping.
While most pallets are wooden, pallets can also be made of plastic, metal, paper, and recycled materials. Each material has advantages and disadvantages.
