DuPont paper, waterproof and breathable technical material

There is a material that is thinner and lighter than paper, yet strong and tear-resistant. It has a unique texture and touch, is waterproof, stain-resistant, environmentally friendly and recyclable. It can be soft, hard, processable, printable, pure and white or colorful. It is DuPont paper, the full name is Tyvek, and the Chinese name is translated as Tyvek.

What is DuPont paper?

DuPont paper is a high-density polyethylene material developed by DuPont in the 1950s using a special process, and commercial production began in the 1960s. Due to the special production method, DuPont paper combines the excellent characteristics of film and fabric materials, and is waterproof, breathable, lightweight, strong, weather-resistant, tear-resistant, puncture-resistant, anti-bacterial, anti-mite, dust-proof, Diffuse reflectivity, high reflectivity, UV resistance, printability, easy processing, smooth touch, unique texture, environmentally friendly and recyclable, etc.

It is precisely because of the excellent properties of DuPont paper that it has been used in various fields for decades, including personal protection, medical packaging, building envelopes, industrial packaging, printing and packaging and other industrial fields.

In recent years, the greater potential of DuPont paper has been tapped by designers and applied to various fashion and design fields. Clothing, bags, lighting, indoor and outdoor design, cultural and creative products, etc., the various creative products created are deeply attractive to consumers.

Manufacturing process of DuPont paper

DuPont paper adopts multi-stage flash evaporation technology in the manufacturing process, the polymer is processed into extremely fine fibers after hot melting, and then the finished product is made by thermal bonding technology;

This process, which is similar to the principle of papermaking, endows it with excellent characteristics of paper, but because the base material is not the plant organic fiber used in papermaking, high-density polyethylene fiber is used, which gives it many properties that paper does not have. , greatly expanded its use field, medicine, industry, and packaging all have its presence.
