The cardboard cup manufacturing process
Cardboard cups are omnipresent objects in our daily life. They accompany us during our coffee breaks, our take -out meals, and many other opportunities. Often used to reduce the environmental footprint compared to plastic cups, their manufacture requires a complex and fascinating process which involves many steps.
The selection of materials
The first step in the cardboard cup manufacturing process begins with the selection of basic materials. The choice material is generally recycled cardboard, which is economical and environmentally friendly. It is important to note that the cardboard used is often made up of several layers to guarantee the solidity of the cup.
Cutting cardboard sheets
Once manufactured, the cardboard leaves are cut into large flat forms, ready to be transformed into cups. Each sheet contains several stew templates to maximize production efficiency.
Goblets training
The large cardboard sheets are then transported to a forming machine which gives the cardboard its cup shape. This machine uses a series of rolls and folds to give the cardboard the cylindrical shape we know. The bottom of the cup is also formed during this stage.
Internal coating application
To prevent liquids from infiltrating through the cardboard and making them airtight, an interior coating is applied in cardboard cups. Generally, that is to say for most Cardboard cup And Kraft cups From the market, it is a thin layer of polyethylene that makes the cup waterproof. This step is crucial for cups intended to contain hot drinks, because it prevents the cup from softening or fleeing. Another manufacturing technique makes it possible to completely exclude plastic in the final product. Indeed, it is possible to apply a thin aqueous layer which makes it possible to manufacture 100% plastic cups, available on the COVR site.
Cutting and finish
After the training of goblets and the application of the interior coating, the cardboard leaves are cut into individual cups. The edges are often rolled to ensure that they are smooth and without sharp edges. The size of the cups can vary depending on the needs of the customer, ranging from small espresso cups to large sizes for cold drinks.
Quality Control
Before being packed and shipped, the goblets go through rigorous quality control to ensure that they comply with food and quality security standards. Any defect is eliminated, ensuring that cups reach consumers in perfect condition.
