Exposing the Hidden Dangers of Unqualified Plastic Cups? (Part 4)

A cup has a story; life has warmth—hello everyone, "Dong Dong's Cup Talk" is here. In previous articles, I’ve shared information about the various plastic materials used in manufacturing plastic cups. If you'd like to learn more, feel free to look back at my earlier posts. https://www.umbottle.com/ProductsDetail-VB-10236.htmlToday, I want to discuss the potential hazards of unqualified plastic cups, especially those designed for children and infants. Regarding materials, I will focus solely on plastic cups made from PP, PPSU, and TRITAN, as well as the issues associated with unqualified plastic cups. Given the extensive content, I’ll break it down into several separate posts to share with you all.

In my previous shares, much of the content was divided into multiple parts. Some eager readers may have only looked at one post about the issues they were concerned with. If you wish to gain a comprehensive understanding, https://www.umbottle.com/ProductsDetail-VB-10236.htmlplease browse through the posts in order. I’ve tried to consider each topic as thoroughly as possible to address your concerns.

IV. Counterfeit Materials: The Chaos in the Market, Using Tritan as an Example

Counterfeit Materials:

This refers to the practice where manufacturers use inferior or mismatched low-cost materials to cut costs, https://www.umbottle.com/ProductsDetail-VB-10236.htmlwhile falsely labeling them as high-performance, high-value materials.

Examples of Tritan Counterfeits:

1. Ordinary PET or PS:

These materials are far cheaper than Tritan but have poor heat resistance (PET withstands about 70°C, PS about 90°C). Cups made from these materials can easily deform when filled with hot water and may release harmful substances. https://www.umbottle.com/ProductsDetail-VB-10236.htmlOrdinary consumers often struggle to distinguish them from genuine Tritan based on appearance alone.

2. Recycled Materials with Odor Masking Agents:

Some manufacturers use recycled materials to produce cup bodies and then add fragrances or odor-masking agents to cover up the plastic smell, passing them off as new Tritan products.

Case Study:

In 2022, during a special inspection, a local market regulatory authority discovered children's cups labeled as "Tritan" material. Laboratory tests revealed that the main component was actually PS. https://www.umbottle.com/ProductsDetail-VB-10236.htmlAdditionally, the cups showed severe deformation during high- and low-temperature tests. Despite this, their selling price was comparable to that of genuine Tritan cups, constituting a typical case of fraud.
