PET bottles are a common type of bottle in our lives. They have good transparency and the shape of the contents can be clearly seen through the bottle body. Of course, there are also bottles with brown bottles. So, where are brown bottles mainly used and what are their characteristics?
Brown PET bottles are made by adding color masterbatch to the raw materials, which changes the original color of the raw materials. Ordinary colorless bottles are light-transmissive. If they are used to contain light-sensitive medicines, they will easily cause the contents to decompose or deteriorate without adding black paper or carton covers to block light. Brown is a special color that can prevent the transmission of light below 465mm. The shorter the wavelength of light, the greater the basic energy, and the easier it is for light-sensitive substances to undergo photochemical degradation reactions. Light with wavelengths above 465mm has low energy, so brown bottles can protect against light and reduce photochemical degradation of the interior.
In terms of bottle application, bottles of this color are mainly used for packaging oral liquid drugs. Oral liquid absorbs the technological characteristics of traditional Chinese medicine injection and is obtained by further refining, concentrating and encapsulating the decoction. Compared with tablets, capsules and other dosage forms, oral liquid is better absorbed and is a rapidly developing type of pharmaceutical preparations. dosage form. This kind of medicine cannot be exposed to light when stored, otherwise it will easily cause certain substances in the medicine to decompose and lose effectiveness, so brown bottles are chosen for packaging.
To sum up, brown PET bottles are mainly used to store light-sensitive oral liquid drugs. In addition, some light-sensitive tablets, such as nitroglycerin tablets, will also choose brown bottles.
