A modern day beverage can is made out of a metal container that comes
in various shapes designed to hold a certain fixed amount of the
liquid like soft drinks, alcoholic drinks, teas, fruit juices, energy
drinks, etc. Any quality cans are made up of either aluminium
or tin plated steel.
Cans can be classified into different categories depending upon their
structure like 3 piece cans and 2 piece cans, depending upon their
material like aluminium or steel cans and depending upon their degree
of internal pressure like pressurised and vacuum cans. The process to
make any can differs slightly with the major part of the production
process remaining the same. The most diverse items in can production
are the can openings generally known as easy open ends.
Early cans had no such easy to open tabs and had to be either opened
with a special device called the churchkey or people used to simply
punch two holes on it on either side of the top, a larger one to
drink and a smaller one to allow the air to enter.
The modern day quality cans are usually fitted with a variety
of easy open ends procured from an easy open ends supplier.
Most easy open ends supplier shall refer to them simply as
EOEs for convenience and promote them for the convenience they
provide to opening the metal cans without any special can opener
device.
Many variants of these EOEs are now available in the market, namely,
Pop Tab, Stay on Tab, Wide Mouth, Press Button Can, Full Aperture
End, Resealable Lid, and many more. These EOEs come in various
diameters and in various shapes like circular, rectangular and square
with printed or embossed instructions and many times without any
opening instructions depending upon the popularity of the opening
aperture and the ease of use from the customer’s perspective.
The design of quality cans also differs in terms of the
printed material. Some designs are printed directed on the can and
sometimes embossed as well during the production process itself.
While some others have a wrap around plastic design which is printed
instead of the can which provides more flexibility to the printing
process.
