Dubang Paper
Dubang paper is a product-source label for paper-like EDC bag and pouch materials. Tyvek is made from high-density polyethylene fibres, but appearance or a generic label does not independently authenticate that brand or supplier.

Roll-bag bodies, spinner pouches and optional outer layers
In these EDC cases, the material called Dubang paper in the maker sources appears in storage systems rather than the load-bearing body of a spinner or slider. It forms a roll-bag body, an included spinner pouch, or one of two outer-material options for a portable pouch.
DuPont describes Tyvek® as a synthetic sheet material made from continuous high-density polyethylene fibres, with paper-like hard structures and fabric-like soft structures. This page retains the makers’ Dubang paper wording. Without a grade, supply-chain record or certification, it has not independently verified that these products use genuine DuPont Tyvek®.
The complete Chugan package. The source lists a Dubang-paper spinner pouch alongside the tin, spinner and identity card.
Paper-like does not mean ordinary paper
DuPont states that Tyvek® is formed from continuous high-density polyethylene fibres and can have a paper-like or fabric-like structure. A paper, cloth or nonwoven appearance alone cannot identify Tyvek.
This page includes only parts that product sources explicitly call Dubang paper. Without a grade or supply-chain record, the exact basis weight, hard or soft structure, protection level and authenticity remain unknown.
Yingshi: a Dubang-paper body around a mixed-material storage system
ATOM describes its Yingshi EDC roll bag with a Dubang-paper body, a nylon structural frame and inner sub-pouches made from diving-suit padding material. Each material has its own position; the bag cannot be reduced to a single material.
The sub-pouches can be detached and rearranged, the bag can unfold into a table mat, and two safety cords use magnetic blocks. Those features belong to the product design rather than to Dubang paper by itself.
Chugan: Dubang paper appears in the included spinner pouch
The TICK SPIN Chugan package contains a tin, a Dubang-paper spinner pouch, the spinner and an identity card. The steel, zirconium, titanium and tungsten spinner versions sit at a different material level; the source does not describe the spinner body as Dubang paper.
The maker also says that the factory-made pouch did not reach its intended finish. That is a maker assessment of this batch of accessories, not a general conclusion about Tyvek.
Carry: one of two outer-material options
The Carry portable pouch lists Oxford cloth and Dubang paper as two alternative outer materials. Its complete dimensions are 120 × 92 × 46 mm, and a glow-in-the-dark hook-and-loop patch is included. The dimensions describe the finished pouch rather than the sheet material.
Oxford cloth and Dubang paper are parallel options. The article does not label each photographed pouch by version, so surface texture alone cannot determine which example uses which material.
Read the product in three layers
The first layer is the outer surface or body material, the second is the frame, lining and sub-pouches, and the third is the magnetic hardware, fasteners and included packaging. A material can be assigned to a part only where the source makes that relationship explicit.
IN THESE FAMILIES
The Chugan package shows Dubang paper used for an included spinner pouch, while the spinner, tin and identity card are separate objects.

Common confusions
From Read the product in three layers
Dubang paper is a common Chinese consumer term, while Tyvek® is a DuPont brand material. When a product description provides no grade or authentication, this page records the maker’s stated material without treating the background reference as product certification.
