|Process And Technology
- The general
structure of paper cup (bowl) shaping machine is composed of five parts.
They are the first stage, the medium stage, the second stage, the third
stage and its outer shell.
- The first stage:
mainly finishes transmission of the paper cup's side-wall paper, shaping
side-wall and transferring them to the medium stage after
- The medium stage:
mainly finishes transmission of the cup-bottom paper, shaping
cup-bottom, joining the shaped side-wall and cup-bottom, automatic
transmission and discharging of the shaped cup, and curling the shaped
- The third stage:
mainly includes 45 angle separating, preheating, curing bottom,
rouletting, curling rim and so on mechanisms, which are the important
parts in finishing paper cup.
- The fourth stage:
mainly includes motor, reduction gear and so on. A frequency converter
is used to finish adjusting its speed and providing power.
- The paper-cup
manufacturing sector is expected to expand in a big way in the coming
years following the growing awareness of the ill effects of using
non-food and bio-degradable containers for serving beverages.
- It is also to be
noted that the Indian Railways has recently passed an order banning the
use of plastic cups at railway stations and on trains. A total of
150 million cups is consumed by the Indian Railways and its associates
every year. The CPTA has urged the State Governments, paper
manufacturers, traders, environmentalists and NGOs to initiate a joint
move propagating the use of paper cups.
- An off-shoot from
this trend has been printing on cups undertaken by an ever larger
percentage of the end-users (to ensure their business is promoted). The
underlying issue being a change from foam cups to paper hot cups
generally sees end-users pay 300 to 400% more in price.
Kumamoto and Koshi plants have established a paper-cup recycling system.
As a result of this system, 89.8 kg of paper cups that would have been
incinerated as general waste is now recycled for use in the production
of toilet paper.
paper cups and plates are less damaging to the environment than plastic
ones, they are associated with a `disposable' and, therefore, wasteful
lifestyle. Environmental activists point out that the same employers who
spend on paper cups could encourage the use of reusable mugs, keeping
disposables — plastic, paper or earthen only for emergencies or
