Pharmaceutical plastic bottles are plastic bottles that are blow-molded and are used to pack medicines, liquids, solvents and chemical reagents.
Medical plastic bottles are often made of PET, which has the advantages of not easy to break, good sealing performance, moisture-proof, hygienic, and meets the special requirements of pharmaceutical packaging. It can be directly used for pharmaceutical packaging without washing or drying. Excellent medicinal packaging containers are used for the packaging of oral solid medicines (such as tablets, capsules, granules, etc.) and oral liquid medicines (such as syrups, tinctures, etc.).
Secondly, polyethylene (PE) is also a more commonly used material. PE is divided into high density (HDPE), low density (LDPE) and linear low density (LLDPE). HDPE has high melting point, hardness and strength, low water absorption, good processability and radiation resistance, and is often used in the production of plastic bottles for tablets; LDPE has good flexibility, elongation and impact strength, and can be used Plastic bottles for eye drops; LLDPE has high impact strength, fatigue resistance and abrasion resistance, and is rarely used in pharmaceutical packaging.
Features
Medical plastic bottles are plastic bottles made based on the principle of blow molding. Compared with other plastic hollow packaging containers, there are many special places.
1. Capacity: Due to the particularity of drug packaging and medication, from a few milliliters to about 1,000 milliliters, most of the shapes are round, but also square, oval and other shapes.
2. In order to ensure that the medicine is not damp or deteriorating during the validity period, the medical plastic bottle should have good sealing and barrier properties to prevent the influence of light, heat, water vapor, oxygen, etc. on the medicine.
3. The inner wall of the bottle is in direct contact with the medicine, and the material of the bottle must meet the requirements of the medicine packaging to ensure the safety of the medicine.
4. Oral solid and liquid medicinal plastic bottles are a type of packaging material, which can be used for pharmaceutical packaging without cleaning and sterilization. Therefore, there are high requirements for microbial limits, and the production environment and production process should meet the requirements of relevant laws and regulations.
5. The shape, size, structure, etc. of medicinal plastic bottles should be adapted to the requirements of various types of filling machines of pharmaceutical companies and the requirements of high-speed automatic filling machines.
