How are colored plastic water cups produced?

Hello everyone, "Dong Dong Talks About Cups" is here. Yesterday, the editor shared how to judge a good plastic water cup. Interested friends can read the editor's article yesterday. http://www.umbottle.com/ProductsDetail-VB-10355.htmlToday, the editor continues to bring articles about plastic water cups. I hope you will like them.

When we buy plastic water cups, we find that some are colorless and transparent, some are colored and translucent, some are colored and frosted and translucent, and some are colored and completely opaque. http://www.umbottle.com/ProductsDetail-VB-10355.htmlWhat are the processes used to produce them? What process should we choose to get a better price-performance ratio?

At present, all plastic water cup manufacturers produce colored cups, whether translucent or colored or completely opaque, usually using plastic raw material color or plastic spray painting technology. Plastic raw materials are usually transparent and colorless. http://www.umbottle.com/ProductsDetail-VB-10355.htmlTo produce translucent colored plastic water cups, you need to add color powder to the transparent raw materials to adjust the color to the desired effect, and then the produced plastic water cups are translucent raw material colors. Fully opaque plastic water cups can also be produced using plastic raw material colors and can also be achieved by spray painting. Solid color raw materials require special production, and transparent raw materials are produced into solid color raw materials, and then they are produced and processed.

Why use raw color instead of spray painting? Plastic water cups produced with raw color will still be the raw color of the plastic if they are dropped or bumped during use, http://www.umbottle.com/ProductsDetail-VB-10355.htmlbut plastic water cups produced with spray painting may cause the paint to fall off due to drops or bumps during use, revealing the original color of the plastic, which is not beautiful.

Some friends must ask, since the plastic water cups produced by the spray painting process may fall off, why do manufacturers use plastic elements when producing plastic water cups? This is only because of the production cost considerations of each manufacturer. http://www.umbottle.com/ProductsDetail-VB-10355.htmlAlthough the spray painting process has some shortcomings, the production cost is relatively lower, and the color customization of the water cup will be more flexible, especially when the number of customizations is not large.

Although the use of plastic elements will give a better experience during the use of the water cup, the color needs to be customized, and the manufacturers of plastic raw materials will consider the output ratio. http://www.umbottle.com/ProductsDetail-VB-10355.htmlUsually, the manufacturers of plastic raw materials will require the water cup factory to meet a certain amount of customized colors before they will cooperate with color modulation, but often such an amount is far greater than the actual order quantity. This method will cause the water cup factory to accumulate materials, which will not only increase the material cost but also the storage management cost. Therefore, usually at this time, the manufacturer will also recommend that the purchaser try to use the spray painting process, otherwise the procurement cost will also increase significantly.

The colored water cups mentioned above are mainly for plastic water cups with only one color. If a plastic water cup has multiple colors, most of them are achieved through post-printing process, and some are achieved through multi-color spray painting process. http://www.umbottle.com/ProductsDetail-VB-10355.htmlHowever, due to the poor control and positioning of multi-color spray painting process, the yield rate is reduced, so manufacturers will use printing to achieve it. Currently, there is no way to achieve multiple colors through plastic primary colors.
