Here are some knowledges to let you realize more about the paperboard box
Corrugated paperboard box is what one typically refers to when using the term “cardboard,” and is often used to make various
types of corrugated boxes. Corrugated board consists of several layers of paperboard, typically two outer layers and an
inner corrugated layer. However, the internal corrugated layer is typically made of a different kind of pulp, resulting in a
thinner kind of paperboard that isn’t suitable to be used in most paperboard applications but is perfect for corrugating, as it
can easily assume a rippled form.
The corrugated cardboard manufacturing process uses corrugators, machines that enable the material to be processed
without warping and can run at high speeds. The corrugated layer, called the medium, assumes a rippled or fluted pattern
as it is heated, wetted, and formed by wheels. An adhesive, typically starch-based, is then used to join the medium to one of
two outer paperboard layers.
The two outer layers of paperboard, called linerboards, are humidified so that joining the layers is easier during
formation. Once the final corrugated board has been created, the component undergoes drying and pressing by hot plates.
Corrugated boxes are a more durable form of cardboard box that is constructed of corrugated material. This material
contains a fluted sheet sandwiched between two outer layers of paperboard. A corrugated box can be used as a shipping
box or a storage box by virtue of its increased durability when compared with paperboard-based boxes.
Corrugated boxes are characterized by their flute profiles, which have a letter designation of A, B, C, E, or F. The flute profile
is representative of the wall thickness of the corrugated box and is also a measure of the stacking ability and overall
strength of the box.
A flute is ¼” high. It’s commonly used for fragile products or to add strength to other corrugated cardboard thanks to its
stacking strength, compression, and cushioning properties.
B flute, at ⅛”, is also used for padding and features compression and puncture resistance. Both B and C fluting are
good for printing purposes.
C flute, which is 11/64”, is used in shipping boxes and to secure heavier items. Like A and B fluting, it features crush
and compression resistance. This is the most commonly used corrugated medium
E flute, at 1/16”, is used in displays, retail packaging, and other applications where printing may be necessary and it’s
important to save space. This is one of the weakest types of flute.
F flute, which is 1/32”, makes for the thinnest corrugated cardboard, including shoeboxes and clamshell packaging. It
allows the packaging to be stiffer while using less fiber.
A corrugated box consists of layers of fluting and flat paperboard, which can range from single face and single wall to double wall or triple wall.
Single face board is a single layer of paperboard adhered on one side to corrugated fluting, often used as a product
wrapper.
A single wall corrugated box features paperboard on both sides of the fluting. This makes up the most common type of
corrugated cardboard packaging, best for moving or shipping products that aren’t too delicate.
Double wall corrugated board includes two sections of corrugated fluting and three layers of paperboard. Double wall
is better adapted to stacking than single wall corrugated board, and it can be used for industrial containers and
heavier products.
Similarly, a triple wall corrugated box will have three sections of fluting and four layers of paperboard. Triple wall
corrugated board is closer to wood crates in terms of strength, and it can be used to cushion and support heavy and
industrial products.
Although the flute gives an indicator of how strong a corrugated box will be, box strength is also tested through an edge
crush test. An edge crush test, or ECT, demonstrates the stacking strength of the cardboard by compressing a small piece
of cardboard edge-on between two plates that are positioned perpendicular to the flutes in the cardboard. Using edge crush
test values will enable the buyer to determine exactly how many pounds of product can fit safely inside each type of
corrugated paperboard box.
