The manufacturing of paper cups started throughout early 1900s, mainly with the intent of preventing diseases. Since such cups are usually not meant for reuse, the consumption of drinks from these cups places off the transfer of germs, thus selling good health. Other than being hygienic, paper cups offer the comfort of use and make life easier. Specialists estimate the worldwide consumption of Printed Paper Cups cups to 2.0 billion per annum.
The manufacturing strategy of paper cups
Massive rolls of paper are procured by the manufacturing unit. One facet of the paper is coated with an especially formulated plastic to make the interior of the cup. Subsequent, the roll is fed to a machine for printing designs on the other side. As soon as the printing is completed, one other machine is employed to separately cut the paper containing the design into small sheets, that 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 handed via a big machine, which rolls them to a cylindrical shape whereas concurrently sealing them by applying warmth on the wax already applied 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 bottom of the cups has been obtained, is thrown out and recycled. Lastly, the cylinders and bases, which go to make the complete cups, are sealed collectively by way of a warmth process.
Rim formation and packaging
A chute is employed for transferring the cups to a distinct machine, which varieties the rim of the cup by rolling paper on its top. The cups are then sent for packaging, the place they’re dropped into the correct sized tubes and stacks get made. After the required number of cups gets collected in one stack, it is handed by way of another machine, which wraps a plastic sheet round it and finally seals the sheet. That is the bundle ready for shipment. The complete process from making to packaging of cups takes almost one minute.
It’s rare to have leaky cups. But, cups are arbitrarily taken out from the line of production and tested. The cups taken out for testing are placed in a specially designed holder on high of a mirror, which enables the particular person carrying the test to ensure it isn’t leaking. On detecting a leak, the particular line of manufacturing is stopped until the issue is situated and corrected.
