With the continuous improvement of various production processes, high-density polyethylene raw materials are processed into various forms of high-density polyethylene bottles for use in all walks of life. Among many application fields, medical packaging is a special one.

HDPE is non-toxic, odorless, and feels like wax. It has excellent low-temperature performance, can be used in the environment of - 70-100 ℃, can resist most acid and alkali corrosion, has good flexibility, and is light and not fragile. Drug packaging is generally divided into two categories: solid and liquid. High density polyethylene bottles can be used for both solid and liquid drugs. Some liquid drugs are easy to decompose when exposed to light. They can be made into brown bottles by adding color masterbatch to the raw materials to better protect the drugs. Solid drugs are easy to deteriorate due to dampness, so high-density polyethylene bottles used for solid drug packaging will add desiccant in the bottle to maintain the dryness of the environment in the bottle and protect the stability of drugs.

Drug packaging plays an important role in the safety and effectiveness of drugs. The industry has also formulated corresponding quality standards for high-density polyethylene bottles for solid and liquid drug packaging, and has made detailed provisions on the appearance, dissolution, drop resistance, abnormal toxicity and other indicators and detection methods of bottles to ensure that the packaging quality meets the standard requirements.

High density polyethylene bottles are one of the common packaging in the pharmaceutical industry at present. In addition, polymer materials such as polyester bottles and polypropylene bottles also have a certain range of applications in the field of pharmaceutical packaging. We will wait and see whether there will be more novel packaging in the future.
