With the development of animal husbandry and the further implementation of the national compulsory immunization program, the market demand for veterinary vaccine vials is steadily increasing. The quality of the packaging plays an important role in the stability and safety of the vaccine, so what are the commonly used materials for vaccine bottles?
Veterinary vaccines are mainly divided into attenuated live vaccines and inactivated vaccines. The attenuated live vaccines are made of glass, and the inactivated vaccines are made of plastic. Commonly used plastic materials include polyethylene and polypropylene.
Polypropylene: white waxy material, transparent and light in appearance, colorless, odorless, non-toxic, good high temperature resistance, resistant to most acid and alkali solvents, and generally used polypropylene material for transparency or sterilization For veterinary drug companies with requirements, this material can be terminally sterilized or made into translucent vaccine bottles. Some vaccines are very sensitive to light and are easy to decompose and deteriorate. Therefore, color masterbatches are added to the packaging and processing materials to make brown vaccine bottles to better store the vaccine.
Polyethylene: non-toxic and odorless, feels like wax, the lowest operating temperature can reach -100~-70°C, it is insoluble in general solvents at room temperature, has low water absorption, excellent electrical insulation, and has better toughness than polypropylene. The material is also a common raw material for various plastic bottles.
On the whole, plastic veterinary vaccine bottles are mainly polyethylene and polypropylene. These two materials can basically meet the various needs of pharmaceutical companies for the storage and sterilization of inactivated vaccines.
