What is medical dialysis paper?
Dialysis paper is also called Glue coated Dialyzing paper. This paper is primarily used in medical sterilization. It is used to pack medical devices for sterilization. One side is high-density polyvinyl alcohol, and the other is dialysis paper. The advantage of dialysis paper is that it can enter and exit steam, but it is impermeable. When in use, the piece can be sealed with a sealing machine.

How to Choose Medical Dialyzing Paper?
The choice of medical paper plastic bags is mainly due to paper. The price difference of different dialysis papers is four or five times. It also depends on the added value of your product and how the product is intended to be positioned. Below, I list some materials of medical dialysis paper for the packaging of medical devices to be sterilized for reference only.
Price
DuPont Tyvek paper in the United States is twice as much as 83g paper in France, and 83g paper in France is about twice as much as 60g paper in Britain. (70 grams is about 10% more expensive than 60 grams, tyvek1073b is about 10% more costly than tyvek1059b, and tyvek1059 is about 35% more expensive than 2fs.) Sometimes any paper bag can be used to pack the same medical equipment.
Thickness
60g / m2 , 70g / m2, France made 83g / m2, 75g / m2 DuPont tyvek 1073B, 64g / m2 DuPont tyvek 1059B and 56g / m2 DuPont tyvek 2fs
Supplementary notes:
1. The paper of the same manufacturer, the thicker, the more expensive. If it is not the same model, it can not be compared.
2. DuPont paper is not as substantial as French 83 grams, but it is stronger than French 83 grams.
Function
It is mainly used for the packaging of medical devices to be sterilized; usually, EO ethylene oxide sterilized or steam high-temperature and high-pressure steam-sterilized medical devices, such as medical catheters, hemostatic gauze, artificial joints, high-frequency surgical electrodes, medical probes, indwelling needles, medical balloons, medical accessories, surgical clothes, laryngeal masks, disposable blood circuits, and other medical devices.
Sterilized Medical Device Packaging Development Status
Global background:
The sterile barrier system of medical devices originated from the United States, Europe, and other countries and regions with a relatively sound medical system. With the gradual maturity of the market, the scientific level of medical device management is gradually improved. In the 1990s, the introduction and subsequent updates of en 868 standards of the European Standards Committee and the ISO 11607 standard of the International Committee for standardization made the sterile barrier system the essential requirement of medical device packaging in European and American countries. According to relevant statistics, as early as 2003, the final global sterilization medical device packaging sales reached 1.65 billion US dollars. Among them, the total sales in North America and Europe accounted for 72%, the primary sterile barrier systems market. Due to the relatively backward medical and health conditions, the sales proportion in the Asian market is only 20%, which does not match its vast population.
In China:
By 2015, the market scale of special paper for medical packaging in China was about 1.22 billion. Among them, dialysis paper and wrinkle paper consumption are about 55000 tons, and the market scale is about 600 million. Others include film-coated paper and film-coated paper for medical packaging. Considering the size of China’s population and the development level of the medical service system, there is still much room for improvement in the dialysis paper market of the sterile barrier system.
Development of China Sterile Dialysis Paper Industry
In developed countries, dialysis materials of sterile barrier systems have entered a relatively mature industrial stage with the development of sterile barrier systems. Due to the limitations of various factors, the domestic market is still in a period of expansion, and the development of the industry is facing a variety of opportunities and challenges.
(1) Aging of the population, increasing the incidence rate of chronic diseases, and increasing awareness of residents’ health care will further expand demand for medical devices and packaging.
(2) Terminal diagnosis and treatment institutions do not pay enough attention to the sterile barrier system of medical devices, and there is an urgent need to improve the domestic application penetration rate;
(3) Industry standards need to be further improved to guide the healthy and orderly development of the industry.
At present, most of the dialysis paper enterprises of the sterile barrier system of medical devices in China are converted from the fields of food packaging paper and cigarette paper. The industrial development time is short, and the market is scattered, the quality standard is low, there are many repeated low-end products.
The manufacturing and management levels are still far behind large foreign enterprises.
In the future, China also needs to improve the industry management system further guide enterprises to improve their R & D and manufacturing level.
Encourage enterprises to become bigger and stronger through mergers to promote the healthy development of the industry and enhance the sector their foreign competitiveness.
Automatic Slitting Machine suitable for Dialysis Paper Rolls
The medical pouch-making machine needs narrow roll unwinding, so a slitter and rewinder machine is needed.
The standard pouch sizes are 57x130mm, 83x160mm, 70x260mm, 90x260mm, 135x260mm, 135x280mm,
155x260mm, 190x360mm, 305x430mm.
But the Medical Dialysis Paper Made Sterilization Self Sealing Pouch Machine could make 2 bags, 3 bags with more sealing molds during production.
The popular pouch-making machine width is 600 and 800 model. That means if you got a 1300mm width dialyzing paper jumbo roll, you need to slit it into 2 small rolls with 600mm width.
RJ-A series automatic slitting and rewinding machine can fulfill the slit width you need. The slitting blade’s position is adjustable. The min. slit width is 50mm.
