There are two main types of DuPont paper, namely high-density polyethylene material and meta aramid fiber material.

High density polyethylene material, also known as Tyvek, is called Tyvek in Chinese. This material was developed by DuPont and combines the lightweight of paper with the strength of plastic, while also offering durability, waterproofing, and breathability. Tyvek was invented in the 1950s and began commercial production in the 1960s. It is widely used in various daily necessities such as handbags, bento bags, watch straps, etc.

The meta aramid fiber material, also known as Nomex, is called Nomex in Chinese. This material is also produced by DuPont and, unlike high-density polyethylene materials, has special properties that are suitable for applications that require special protection.

These two materials are known as DuPont paper due to their unique properties and wide range of applications, but in reality they are two different materials used in different scenarios and needs.
