What are the advantages and disadvantages of plastic water cups?

Plastic water cups are cheap, lightweight and practical, and have quickly become popular around the world since 1997. However, in recent years, plastic water cups have experienced continued sluggish sales. What is the reason for this phenomenon? Let’s start with the advantages and disadvantages of plastic water cups.

It is well known that plastic water cups are lightweight. Since plastic materials are easy to shape, the shape of plastic water cups will be more personalized and fashionable compared to water cups made of other materials. The processing process of plastic water cups is relatively simple, the material price is low, the processing cycle is short, the speed is fast, the defective product rate and other reasons result in the low price of plastic water cups. These are the advantages of plastic water cups.

However, plastic water cups also have some shortcomings, such as cracking due to the influence of the environment and water temperature, and plastic cups are not resistant to falling. The most serious problem is that among all the current plastic materials, not many are truly harmless, although many plastic materials are food grade, but once the material temperature requirements are exceeded, it will become a harmful material, such as PC and AS. Once the water temperature exceeds 70°C, the material will release bisphenol A, which may deform or even break the water cup. It is precisely because the material cannot meet people’s safety needs that plastic water cups other than tritan have been strictly prohibited from entering the market in the European market since 2017. Later, the US market also began to propose similar regulations, and then more and more countries and regions began to impose restrictions on plastic materials. Water cups have higher requirements and restrictions. This has also caused the plastic water cup market to continue to decline in recent years.

As human civilization continues to progress and technology continues to innovate, more new plastic materials will be born on the market, such as tritan materials, which have been recognized by the global market in recent years. This was developed by the American Eastman Company and is aimed at traditional plastic materials. , more durable, safer, high temperature resistant, non-deformable, and does not contain bisphenol A. Materials like this will continue to be developed with the development of technology, and plastic water cups will also move from one trough to another peak.
