Double-necked bottle is a common packaging container in our life. It is mainly used for the storage of various disinfectants, fish medicine, veterinary medicine and other solutions. It has the characteristics of good barrier properties, light weight and easy transportation. Benzalkonium bromide solution is also the packaging of choice.

Benzalkonium bromide solution is a kind of cationic surfactant bactericide, which can change the permeability of bacterial cytoplasmic membrane, make bacterial cytoplasmic material extravasate, hinder its metabolism and play a killing effect. It has a strong killing effect on gram-positive bacterial propagules, but is ineffective against Pseudomonas aeruginosa, acid-fast bacilli and bacterial spores. It can quickly combine with protein, and its effect is significantly reduced in the presence of blood, cotton, fiber and other organic matter. It is used for sterilization and disinfection of medicine, cosmetics and water treatment, as well as for hard surface cleaning and disinfection and deodorization. Non-oxidative bactericide and algaecide, slime stripper and cleaning agent. It has the functions of cleaning, sterilization and algae killing, and is widely used in sterilization, disinfection, anticorrosion, emulsification, descaling, solubilization and so on. Its bactericidal activity is better than that of Jieerfen, and its toxicity is lower than that of Jieerfen. Usually, its concentration is 50-100 mg/L.

The volume of twin neck bottle used to store the benzalkonium bromide solution is generally more than 500ml, mainly because of its wide application range and large demand. Before use, it needs to be diluted, so there will be a transparent graduation line on the bottle, so that the dose of the solution can be easily seen.

In practical applications, enterprises will pay more attention to whether there is liquid leakage in double-neck bottles, which requires packaging material manufacturers to strictly control the material matching, sealing methods, quality control and other aspects to ensure product quality.
