1.2 TYPES OF SEALING MACHINE
1. Cellophane sealing machine: The cellophane sealing machines are used for polyethene and other associated materials.
2. Fibre bag sealing machine: This type seals products that are usually contained in fibre salts.
3. Can sealing machine: This is mostly used in the metallurgical industries for sealing metal can etc.
4. Paper sealing machine: Products that are packaged in bags are usually sealed using the vacuum sealing machine type.
1.3 OTHER USES OF CELLOPHANE ARE
a. As a sealant: Cellophane is used in the sealing of plastic contains.
b.
In manufacturing of rain coats: Cellophane (polyethane) with
high densities are used in the manufacturing of rain coats.
c. They are used as additives to other products.
d.
In lamination: Because many current packaging application
requires combination of properties not available in any single packaging
film, two or more different films, are often laminated to obtain the
desired properties. An extremely wide range of properties can be
achieved in various combination of cellophane with polyethene aluminum
foil, rubber, hydrochloride film, wax and pa per.
e.
Printing: A printed design or message may be applied to gravure,
flexographic or letter press printing, and several colours may be
applied consecutive to cellophane.
g. Hot – melt
coating: One important example is its use in the direct wrap,
used on some varieties of processed cheese.
In our economy
today, there is ever increasing demand for cellophanes and as such, it
is very necessary to construct a cellophane sealing machine to meet the
needs of the people. The project in guestion is aimed at providing this
machine at a relatively cheap cost from locally gathered materials,
thus, reducing the cost of production of cellophane sealing machine as
well as to enhance the effective utilization of cellophane products.
