- Bubble wrap is a
flexible transparent plastic material used for packing fragile items
- Air bubble film is a
two layer laminated low density polyethylene film with entrapped
air inside, between the two layers in bubble form in some orderly
fashion. Air bubbles render cushioning effect
- Air Bubble cushioning
starts as polyethylene resin, in the form of beads about the size of
small peas. The beads go into an extruder - a long cylinder with a
screw inside that runs its entire length. As the screw is turned,
heat builds up and the resin melts into a liquid that is squeezed
out of the cylinder into two stacked sheets of clear plastic film.
One layer of the film is wrapped around a drum with holes punched in
it, and suction is applied drawing one web of film into the holes
that form the bubbles. The second layer of film is then laminated
over the first so that when the two films are joined, they stick
together and trap the air in the bubbles.
- Bubble packaging does
not add weight, but it does add cubes affecting the “dimensional
weight” you are charged.
- While originally being
used primarily for packaging for electronics equipment, today the
vast majority of Bubble Wrap made is used for food packaging.
Because bubble wrap makes a
satisfying popping sound when compressed and ruptured & it is often
used as a source of
amusement.
