Corrugated board:- Corrugated cardboard is a stiff, strong, and light weight
material made from a combination of two sheets called liners glued to the
corrugated inner me-
dium called fluting.
These three layers of
paper are assembled
in a way which gives
the overall structure,
a better strength than
that of each distinct
layer. One sided corrugated boards having a flute with one layer of sheet
are called sigle faced corrugated boards. A flute with sheets on both sides
is called single wall corrugated or double faced corrugated boards. Single
walled, double walled or triple walled corrugated paper boards are com-
monly used for outer packagings such as shipping cartons and containers.Special packages
Blister packs:- It is a rigid plastic packing method. This plastic is thermoformed
around the front face of product
allowing it to view through the
transparent plastic. The blister
is adhered on to a printed paper
board backing on which the
product information are
displayed. Hinged or double
blisters (clam shell) are formed
around both sides of the product
allowing for complete product
visibility. Graphics can also be
printed directly on the plastic
structure. Battery packs, toys
etc. are examples. Capsules and tablets are also blister packed but backed
with aluminium foil instead of paper board.
Bubble wrap:- It is a special type of package used for packing fragile products,
electronics items, etc. It is a pliable transparent plastic material in which
regularly spaced, protruding air-filled bubbles provide cushioning for fragile
items.
Shrink wrap:- Also called shrink film is a material made up of polymer plastic
film. When heat is applied, it shrinks tightly over whatever it is covering.
