Background technology
It is at present that vial, plastic bottle and non-PVC films are soft respectively there are three types of product is packed in China transfusion package field
Bag (or PVC soft bags), first two pack product in Clinical practice, need to be inserted into vent line, air is introduced into solution,
Pressure difference is generated, infusion at this time is in Full-open state, and the molecule and microorganism in air can enter in vial or mould
Expect to pollute infusion in bottle, potential hazard is caused to clinical application.Clinically although used PVC soft bags overcome above-mentioned
Defect, but there is also weakness：PVC soft bags are poor to the insulating of water, moisture and air, are not easy long-term preservation；To some drugs
There are certain adsorptivities；Leachable is more；The plasticizer phthalic acid ester added is kind of a potential carcinogen.The nineties
The non-PVC-soft-bag that America and Europe grows up overcomes the defect of above-mentioned infusion packaging material, has the following advantages that：Not plasticizer-containing, nothing
The danger of phthalic acid ester leakage；To thermostabilization, transparency can not be influenced in 121 DEG C of high steam sterilizings；Moisture is penetrated
Property it is extremely low, make infusion solution keep stablize, it is ensured that the Storage period of product；Inertia is fabulous, does not generate chemical reaction with drug,
