Sterilization Packaging Q&A 

Sterilization Packaging Q&A

1.What is the sterilization packing for medical instrument?
Defined as EN-868 & ISO-11607, it is the primary packaging for medical instruments with microorganism Barrier, Sterilizable, and sustained and Shelf-life performances

 

2. How to design for sterilization packing of disposable medical instruments?
When choosing sterilization packing for medical instruments, you should consider factors as following:
a. methods of sterilization
b. volume and weight of the loading instrument
c. Validated date
d. convenience of use

 

3.may medical sterilization paper to film pouches be printed in multicolor or complex contents? And what contents have to be printed on the pouches?
a. As EN-868-5,printing can not be more than 50% of pouch in area, and the ink must not reach the instruments inside. So medical packing is not fit to printed complex contents but the simple is better.
b. As “The Standard Medical instruments marks and management” published by FDA in USA, general requirements suitable for all the medical instruments include company name and address (marks of the medical instruments should contain manufacturer of the instruments, company of packing and dealers’ name and detailed address with street, city, state and zip code); sufficient instructions (instructions should be able to guarantee ordinary users can use equipment safely, and the device can achieve the intended use. That is, all the intended use and the applied scope, all intened use and all intened quantities of patients with different ages and physical conditions, frequency of use, duration of use, maintenance cycles of instruments and other factors should be considered, or applied ways or methods, the necessary preparations before use)

 

4. Why the printing of the medical sterilization packing with paper and film can not be printed so exquisite as that of CCL printing (for example color booklet) ?
Stated clearly in EN-868-1, all to be used for materials of sterilization packing should be sterile. All packaging materials required as a non-toxic disinfectant.  At present, the usual printing methods, such as intaglio, lithography, copperplate and so on, all of them use oily ink. There are risks their volatile content will pollute apparatus. It is better to  use non-toxic water-based ink whose solution is water-based solution. But water-based ink should be printed on flexographic printers, there are some technical restrictions of flexographic printing in certain conditions, such as network points, shadow, color, tiny printing and so on, it  can not be so simple as other printing methods. But packaging medical sterilization is only the rough packaging, so it only need to print the essential illustration on it but the multi-color printing or tiny printing is unnecessary.

 

5. All films packing can use ETO sterilization?
a. Even if the plastic film have apertures can let the gas through, its porosity is not so good as that of the Medical Grade Paper, so it will have some problems on gas input or output. So there will be inadequate sterilization or gas left in the pouch when all plastic pouch loading the instruments are used in ETO sterilization.
b. At present, Standardization Administration of P.R.C have stated in douments instruments for only one use must use the breathable(can be sterilized) packing. For examples in GB 8368-2005 “Infusion sets for single use,gravity feed”, it stipulate materials for packing must use the breathable materials conforming to GB/T 19633-2005 “Packaging for terminally sterilized medical devices”

 

6. What are the differences between Breath Papers from foreign and Breath Papers form China?
At present, it is very indistinct that the says “Breath Papers from foreign” and “Breath Papers form China” in medical packing market. In fact, they should be distinct in “medical grade paper” and ” food grade paper”. Medical grade paper should conform to international standard of  EN868 or ISO11607, and can be used for raw paper for medical packing. But “Breath Papers form China” called now can not be offered valid test report what can prove it conform to medical packing materials norms. We, Suzhou Sigma Medical Supply Co., Ltd usually use medical grade paper supplied by ARJO WIGGINS in France, and we are the Exclusive agent in China of ARJO WIGGINS

(2) ordinary advised stored date: 3 years

 

9. Have medical pouches to change packing after resterilizing? And after resterilizing, does it have validity date of 6 months?
No. Because medical pouches are assumed for only one use. So resterilized, its mateial will be impacted. Relatively, it can not offer the guarantee to the stored validation date of the contents. In a word, to assure the sterilization quality, please change the packing and resterilize and do not resterilize medical pouches only one use after the validation date of 6 months.

 

10. What condition the sterilization pouches are manufacted in?
In accordance with sterile medical equipment production standards Appendix B-B.5 in pharmaceutical industry standards of PRC. And the 6.1.1 of “production Implementation Rules of single-use sterile medical devices” issued by the SDA(State Drug Administration), there are stipulations packaging pouches should be produced in the 300,000 level of aseptic workshop. Our producing plant pass the test to be the workshop of 100,000 level, so our production conditions can absolutely be relied.
