1.1 INTRODUCTION
The portable sealing machine is one of
the most important fabrication of engineers of 20th century, the
achievements led to sweet relieve for Agriculturist, industrialist, marketers
etc. for this purpose, the production of Agricultural and industrials, goods
which need appropriate attention for packaging and storage has been on the
increase.
Previously, the packaging system has done
by the use of paper, clothing material, etc. These methods are either given way
to cellophane packaging system.
Different types of packaging system
emerged owing to the facts of invention of which the most commonly used is the
cellophane packaging and sealing.
It
has the following advantages:
Low
cost of production, high resistance to acid attacks, inertness, corrosion etc.
Polyethylene is used in packaging
goods like ice cream, umbrellas, exercise books, pure water, beverages, weavon,
packet shirts, bread, biscuits etc. the following properties polyethylene
possessed are the reasons for its varieties of purpose that is to say how cost
of production, inertness, resistance to acid, and corrosion water.
The use of polythene cannot be
overemphasized. Most of food packaging for hygienic. The technology of
cellophane permits raw materials of textile industries to be carried with
sealed polyethylene the finished products are either marketed or exported with
polyethylene packaging. Most utensils are packaged with polyethylene. Special
polyethylene materials have been invented of recent that have shock absorber
which gives protection to the breakable material. Since this packaging came up,
there had been a safer conveyance of glass and ceramics materials, especially
for transportation and exportation of finished goods.
Also, it is in packaging most of
electronic gadgets which includes; computers, amplifiers, calculators, radio and T.V sets etc. for safety purposes.
It will be needless talking about polyethylene. Without talking about the
machines used in sealing generally. Some of the machines used in the industries
include cellophane sealing machine used in sealing polyethylene materials,
pneumatic, electrical sealing machine handled by electrical heater and needle
point action and hand sealing.
