Introduction to the production process of eye drops bottle

 Plastic bottles play an important role in people's production and life. No matter what the bottle is, it must be formed and processed, and our common eye drop bottles are no exception. The eye drop bottle is composed of a bottle body, a bottle cap and a dripper. What kind of production technology is used to process the bottle with this structure?

Eye drop bottles are generally made of soft low-density polyethylene raw materials through injection-blowing technology. The capacity ranges from 5ml-15ml. First, the injection machine injects the molten plastic into the injection mold to form a tube blank. The microporous hollow punch is formed; then it is moved to the blow mold while it is hot; then the mold is closed and compressed air is introduced from the pipe of the mandrel to inflate the parison and stick to the cavity wall of the mold; After holding pressure, cooling and shaping, the compressed air is released and the mold is opened to take out the plastic part. This process has the following characteristics:

1. The product has exquisite appearance, accurate size, uniform wall thickness and no flash, and the production of parts does not require secondary processing;

2. Plastic products are made by one-time blow molding of injection moulds, with no waste at the mouth and bottom of the bottle, and the mouth is flat and has good sealing performance;

3. The injection parison has a bottom, so there is no split seam at the bottom of the plastic part, which has high strength and high productivity. It is mostly used for mass production of small plastic parts.

The eye drop bottle produced by the injection-blowing process has good sealing properties and a more high-end appearance. This process is also used in the processing of small refined containers and wide-mouth containers such as cosmetics, daily necessities, food and pharmaceutical packaging bottles.

Eye drop bottle purchase attention

 Eye drops are commonly used drugs in ophthalmology. A bottle of high-quality eye drops requires a high-quality eye drop bottle to protect it. Pharmaceutical companies can consider the following aspects when purchasing eye drop bottles.

1. No matter what raw material you choose, the eye drop bottle must first meet the requirements of non-toxicity and no peculiar smell. The low-density polyethylene (LDPE), polyester (PET) and other materials we see daily can be used as eye drop bottles Based on the raw materials of the drug, the appropriate materials can be selected according to the properties of the drug to better meet its demand for packaging.

2. The airtightness and water vapor permeability of the bottle body and cap. Tightness and water vapor permeability are two important technical indicators of plastic bottles. They have a vital impact on the stability of the packaged product. Pharmaceutical companies need to pay attention to these two indicators when purchasing eye drop bottles.

3. Product quality standards for eye drops. The product quality can be analyzed and judged from the manufacturer's product quality standards, which is convenient for pharmaceutical companies to make correct judgments.

4. Quality assurance system. Auditing suppliers has become an essential part of purchasing eye drop bottles. Through the audit, a comprehensive and correct assessment of the manufacturer's software and hardware facilities, technical equipment, and comprehensive quality level can be made. High-quality manufacturers are more secure in terms of product quality, delivery cycle, and later service.

Eye drops are essential medicines to protect eye health. Pay attention to the importance of eye drops bottles. Choosing high-quality pharmaceutical packaging is a necessary condition to ensure eye health.
