The manufacturing of paper cups began during early 1900s, mainly with the intent of stopping diseases. Since such cups should not meant for reuse, the consumption of drinks from these cups puts off the switch of germs, thus selling good health. Apart from being hygienic, paper cups provide the convenience of use and make life easier. Specialists estimate the worldwide consumption of paper cups to 2.0 billion per annum.
The manufacturing process of paper cups
Massive rolls of paper are procured by the manufacturing unit. One side of the paper is coated with an especially formulated plastic to make the interior of the cup. Next, the roll is fed to a machine for printing designs on the opposite side. As soon as the printing is completed, another machine is employed to individually minimize the paper containing the design into small sheets, which are called flats. One flat goes to make one cup. The dimensions of the ultimate cup is determined by the dimensions of its flat.
The stacks of flats are passed by means of a big machine, which rolls them to a cylindrical form whereas concurrently sealing them by applying heat on the wax already utilized on the interior of the paper forming the cup. The paper that’s concurrently fed from the far finish of this very machine is made into circles, which go to make the base of the paper cups. The spare strip of paper, after the base of the cups has been obtained, is thrown out and recycled. Lastly, the cylinders and bases, which go to make the entire cups, are sealed collectively via a heat process.
Rim formation and packaging
A chute is employed for transferring the cups to a distinct machine, which kinds the rim of the cup by rolling paper on its top. The cups are then despatched for packaging, the place they’re dropped into the proper sized tubes and stacks get made. After the required number of cups gets collected in a single stack, it is passed by way of yet another machine, which wraps a plastic sheet round it and finally seals the sheet. This is the package deal prepared for shipment. The whole process from making to packaging of cups takes almost one minute.
It’s uncommon to have leaky Printed Coffee Cups. Yet, cups are arbitrarily taken out from the line of production and tested. The cups taken out for testing are placed in a specifically designed holder on high of a mirror, which enables the individual carrying the take a look at to make sure it isn’t leaking. On detecting a leak, the actual line of manufacturing is stopped till the problem is positioned and corrected.
