Corrugated board is a multi-layer adhesive body, which consists of
at least one layer of corrugated core paper interlayer (commonly
known as "pit", "corrugated paper", "corrugated core paper" and
"corrugated base paper") and one layer of paperboard (also known as
"boxboard" and "boxboard"). It has high mechanical strength and can
withstand collisions and falls during transportationCorrugated
board is a multi-layer adhesive body, which consists of at least
one layer of corrugated core paper interlayer (commonly known as
"pit", "corrugated paper", "corrugated core paper" and "corrugated
base paper") and one layer of paperboard (also known as "boxboard"
and "boxboard"). It has high mechanical strength and can withstand
collisions and falls during transportation
Also known as corrugated cardboard. It is formed by bonding at
least one layer of corrugated paper and one layer of boxboard,
which has good elasticity and extensibility. It is mainly used for
manufacturing cartons, cartons and other packaging materials for
fragile goods. Native straw pulp and waste paper are beaten to make
raw paperboard similar to yellow paperboard, then rolled into
corrugated shape by mechanical processing, and then bonded with
boxboard paper by adhesive such as sodium silicate on its surface.
The corrugations of corrugated cardboard are like arch doors
connected one by one, which are juxtaposed in a row and supported
each other to form a triangular structure. It has good mechanical
strength, can bear certain pressure from the plane, and is full of
elasticity and good buffering effect; It can be made into liners or
containers of various shapes and sizes according to needs, which is
simpler and faster than plastic buffer materials; It is less
affected by temperature, has good shading property, does not
deteriorate under illumination, and is generally less affected by
humidity, but it is not suitable for long-term use in high humidity
environment, which will affect its intensity.
Classification
According to different combinations, corrugated board can be
divided into the following five types:
1. Paperboard consisting of a layer of core paper and cowhide card
is called "corrugated paperboard". Corrugated cardboard is
generally used only as cushion, spacing and wrapping irregular
objects.
2. Paperboard consisting of a layer of core paper and two layers of
cowhide cards is called "single pit paperboard".
3. Two layers of core paper sandwiched in three layers of cowhide
cards are called "double-pit cardboard". Double-pit paperboard can
be composed of pit papers with different pit widths and different
paper types, such as "B" pit paper and "C" pit paper.
4. The three-layer core paper sandwiched in the four-layer cowhide
card is called "three-pit cardboard".
5. Extra-strong double-body paperboard is developed from single pit
paperboard, and a layer of core paper in the middle is formed by
laminating and bonding two thick core papers.
