What is the eye drops container made of

The eye drops container is composed of a cap, a dropper, and a bottle body, and is a common pharmaceutical packaging for ophthalmic drugs. The material of the packaging plays an important role in maintaining the efficacy of the medicine and protecting the safety during the transportation of the medicine. So, what material is the eye drop bottle made of?

eye drop bottles

Eye drops container is a kind of plastic bottle. Its raw material is mainly low-density polyethylene (LDPE). It is the lightest variety in polyethylene resin. It is milky white, tasteless, odorless, non-toxic, and has no surface. Glossy waxy particles. It has good flexibility, extensibility, electrical insulation, transparency, easy processing and certain air permeability. It has good chemical stability, alkali resistance and general organic solvent resistance. LDPE has been industrialized for more than 70 years. Although with the discovery and development of olefin polymerization catalysts, the variety and output of polyethylene have made great progress, LDPE still occupies an important position, and some pharmaceutical packaging, daily necessities packaging, etc. are used Here comes this raw material.

After adding organic solvent, LDPE is processed by injection blowing process. First, the injection machine injects the molten plastic into the injection mold to form a tube blank. The tube blank is formed on a hollow convex mold with micro holes on the peripheral wall; then it is moved to the blow mold while it is hot; then the mold is closed and passed through the pipe of the mandrel Enter the compressed air to inflate the parison and stick it to the cavity wall of the mold; finally, after holding the pressure, cooling and setting, the compressed air is released and the mold is opened to take out the plastic part.

The eye drops container made of LDPE material is soft, easy to squeeze, and can quickly return to its original shape after squeezing, without creases. Whether it is in terms of the characteristics of the material and the convenience of the patient It is a better raw material for production.
