Further discussion on medical sterilization packaging bags

Medical paper plastic bags, also known as medical sterilization packaging bags or medical disinfection

tube bags in the industry, have many different names for this newly emerged product in recent years.

Let’s temporarily use medical sterilization packaging bags here. So far, as most people, they do not know

what kind of packaging medical paper plastic bags are. The following mainly explains the meaning of

medical paper plastic packaging from a functional perspective. YIPAK hopes to provide a complete

definition of medical paper plastic bags in the industry here.

Medical sterilization packaging bag is a type of packaging used for factory medical devices, hospital

disinfection centers CSSD, supply rooms, operating rooms, and dentistry departments to sterilize and

store sterilized medical devices after sterilization. It is a new, effective, and safer medical device

sterilization packaging product.

Composition of medical sterilization packaging bags:

Simply put, it is made of paper and film through high-temperature hot sealing, which is different from

ordinary plastic packaging; The paper used is medical dialysis paper, which can analyze ethylene oxide

and is a medical grade paper that is easy to dialyze. After sterilization, when opened, it can achieve clean,

no paper scraps falling off, and clean peeling. The membrane of the sterilization bag uses a medical grade

composite membrane. On the outside of the paper, there is usually printing, simple design and printing

of medical colors. Generally, two colors of color change indicator information will be printed. Generally,

there are steam sterilization indicators (Steam), ethylene oxide (ETO), and formalin (FM)

Product characteristics of medical disinfection bags:

Excellent safety; Compared with ordinary sterilization materials, medical sterilization bags have excellent

sterilization safety and excellent dialysis and post sterilization antibacterial functions. The paper surface of

sterilization bags is generally less than 35 micrometers, which is the best physical barrier for

microorganisms and spores. After sterilization, they can be stored for a long time, reducing the efficiency

of hospital disinfection centers and various departments, as well as labor and material costs.

Easy to manage: There are color changing indicators on the sterilization bag, which can clearly distinguish

the sterilization situation. Compared with ordinary medical wrinkled paper and non-woven fabric

, the visibility of the medical film greatly increases the efficiency of hospitals assigning medical devices.

It has waterproof and tear resistance properties; The sterilization bag is made of medical dialysis grade

paper, which has good water vapor resistance and can withstand a dripping test of 8-10 seconds. Paper

and film surfaces have high strength and toughness, and can withstand certain piercing forces from sharp


Product shape: There are double-sided adhesive style self sealing medical disinfection bags and roll

shaped medical disinfection tube bags sealed by a sealing machine.

Sterilization methods in hospital factories

The sterilization method, sterilization process, and post-sterilization treatment must be strictly in

accordance with the “Disinfection Technical Specifications” of the Ministry of Health of the People’s

Republic of China.

A. Steam Sterilization

1.The sterilization conditions for the downward pressure steam sterilizer with sterilization bags are 102.9

kPa, with a temperature of 121 ℃ and a sterilization time of 30 minutes, and regular biological


2.The sterilization conditions for the pre vacuum pressure steam sterilizer with sterilization bags are 205.8

kPa, with a temperature of 134 ℃ and a sterilization time of 4 minutes, and regular biological monitoring.

B: Ethylene oxide sterilization method (ETO)

The sterilization bag is also suitable for ETO ethylene oxide sterilization method. Alternatively, packaging materials with other sterilization methods can be optional.

C. Formalin sterilization method (FM)

Medical disinfection bags are also suitable for formalin sterilization. Anqing Paper Plastic Packaging Materials Co., Ltd. developed formalin color changing indicator ink as early as 2008 and applied it to actual color changing labels.
