What is the material of the eye drop bottle

Ophthalmic drugs are mostly in the form of drops, which also makes eye drop bottles the main packaging in ophthalmic drugs. The material of the packaging is related to whether the medicine can be stored well, so what material is the packaging made of?

10ml plastic eye dropper vial

The material of the eye drop bottle is generally low-density polyethylene (LDPE) raw materials. This is because the eye drops need to be squeezed into the inside of the eye by squeezing the bottle body. Compared with polypropylene, the raw material of LDPE has high density. Polyethylene has a great advantage in flexibility and is convenient for patients to use.

On the other hand, LDPE raw materials can be corrosion resistant to acid and alkali solvents, and will not react when used to contain eye drops, which can ensure the stability of the drug during the validity period.

Eye drop bottles made of LDPE raw materials have a soft body that facilitates the extrusion of the liquid medicine and will not produce creases after being squeezed. This raw material has become a common raw material for plastic bottles.
