Medical crepe paper

Medical crepe paper is the earliest cotton substitute. Due to smaller pore size, health crepe paper has better microbial barrier properties in comparison with cotton cloth; it is usually directly used as packaging material or as an inner packaging material pertaining to rigid containers. Taking China's sanitation industry regulations as one example, sterile items packaged in medical disposable paper bags need to be valid for 1 30 days, and sterile items packaged in disposable medical crepe paper really should be valid for 6 many weeks.
Medical wrinkle packaging paper mainly uses bleached softwood pulp. Bleached hardwood pulp along with HPZ special fiber are destroyed by a hydraulic pulper for a certain ratio and pulped simply by disc grinding. Wet energy agent, sizing agent, softener, and water resistance are added in. Auxiliary materials such when additives are formed inside wire section of the Fourdrinier or inclined wire multi-cylinder paper machine, plus the wet paper is afflicted by wet creping in a cylinder once the dryness of the wet paper is 30-45%. It truly is 30~45, the blade angle in the scraper on the veneer exterior is 35~90?,the speed ratio on the creping cylinder and this heating and drying cylinder is 1. 1~1. 15: 1, and then the creped drenched paper is transferred to the drying Group cylinders regarding drying, take up by way of a paper reel, rewind along with cut into medical crepe packaging paper products. Due into the wet creping under the condition that the dryness of the paper is 30-45%, the hydrogen bonding power between the fibers and also the chemical bonding force of thermosetting resins like wet strength agents haven't been formed, and as the wet paper strength is low, The wrinkles formed following on from the collision of the wrinkle scraper are uniform, and it will have no undesirable phenomena like paper scraps and documents dust.
The mechanical properties of paper packaging supplies are poor, so
- The packaging must not be too tight or even too loose
- Sterilization packages by using paper packaging materials which should not be dragged or perhaps sterilized
- After having wet, the mechanical properties are further reduced to prevent the sterilization package from contaminating with liquid
-- Fully dry during sterilization
Packaging starts with selecting appropriate packaging materials and appearance methods. The packaging method is not only related to the sterilization method and considers the sterilized goods. People have done a nice selection of research on this, and there are lots of kinds of medical packaging materials in the marketplace.
Understanding the sterilization procedures and packaging requirements can help the staff of this sterilization supply center make the ideal decisions when choosing the labels materials. Usually, the staff in the disinfection supply center is faced with the situation that various packaging materials have been used in the work environment. However, it is precise because there is no packaging material suitable for all those sterilization methods, there continues to be a selection process when it is used.
Only packaging materials created specifically for sterilization and okayed by the FDA work extremely well. In addition, for a nice selection of specific sterilization methods, there are numerous basic requirements as is a follower of:
- Pressure steam sterilization The packaging material must be capable to withstand the high temperature of 121℃-135℃, the discharge of air, the penetration of water vapor, and the drying of the packaging material as well as the contents;
- Ethylene oxide sterilization The labels materials must allow the actual penetration and exhaust of ethylene oxide gas (ventilation process);
- Dry heat sterilization Your packaging material must withstand a higher temperature of 160°C-204°C within 2-3 hours without melting, burning up, or other reactions;
: Plasma sterilization Packaging products must withstand extreme vacuum, not absorb sterilizing agencies, not affect the sterilization cycle, and do not damage decorative accessories to be sterilized.
As well as choosing the right appearance materials, the staff with the disinfection supply center need to understand how to use the above packaging materials appropriately to realize the design goals connected with sterilant penetration, aseptic blockers, and aseptic opening on the packaging materials.
