The polypropylene combination cover (easy to pull) used for plastic infusion containers has good temperature resistance and high and low temperature tolerance. In practical use, it has the following advantages:< br> ● High transparency
● Low water vapor permeability
Does not contain plasticizers, can extract trace amounts, and has better compatibility with drugs
● Good biological performance, no heat source, acute toxicity, cytotoxicity, hemolysis phenomenon

The polypropylene combination cover (easy to pull) used for plastic infusion containers has environmental advantages, can burn fully, releases white smoke during combustion, and does not produce irritants or harmful gases. It is an ideal green and environmentally friendly medical packaging material< br> The dosage form of the polypropylene combination cover (easy to pull) used for plastic infusion containers should be a closed drug delivery system, which does not require air to be introduced and relies on atmospheric pressure to compress the bag body to remove the liquid. As there is no need to use infusion devices with ventilation holes during infusion, it avoids pharmaceutical leakage and prevents bacteria and particles in the air from contaminating the drug solution.
