Tablets are solid preparations in the form of tablets or special-shaped tablets that are uniformly mixed with drugs and excipients. These drugs are generally packaged in tablet bottles. According to the different packaging needs of enterprises, most of the materials selected are raw materials such as polypropylene, polyethylene, polyester, etc.
Polypropylene: It has good high temperature resistance, the use temperature range is -30～140℃, the gloss is good, and the common acid, alkali and other organic solvents will not corrode it. However, this material is easily fragile at low temperatures, and certain additives can be added to increase its toughness when making tablet vials.
Polyethylene: non-toxic, odorless, feels like wax, has excellent low temperature performance (the lowest use temperature can reach -70-100 ℃), can withstand most acids and alkalis, is not resistant to oxidizing acids, and has good flexibility , Fading is not fragile, water absorption is small, and electrical insulation is excellent.
Polyester: high impact strength, oil resistance, dilute acid resistance, resistance to most solvents, high transparency, used for pesticide packaging, but it is afraid of high temperature, if it is packed in the sun, it will be deformed, so polyester Pay attention to the transportation of bottles, use cartons and be careful not to dry them.
The above are several commonly used raw materials for tablet vials. Some drugs that are easy to decompose when exposed to light require strong light-shielding packaging. In order to better meet the storage requirements of the drug during the processing process, color masterbatch etc. Brown bottle.
