Tablets are solid preparations in the form of tablets or special-shaped tablets that are uniformly mixed with drugs and excipients. The types of tablets include buccal tablets, sublingual tablets, chewable tablets, effervescent tablets, etc., which are also packaged as tablets. Medicine bottles also come in different materials, so how should pharmaceutical companies choose the right material for packaging?
The commonly used processing raw materials for tablet medicine bottles include polyethylene, polypropylene and polyester. These three raw materials have good barrier properties, which can prevent external impurities and water vapor from infiltrating the inside of the package through the bottle body, affecting the stability of the drug. The difference is that the flexibility of polyethylene is better, while the gloss of polypropylene is very good, and the polyester raw material has high transparency, all three have their own characteristics.
When choosing packaging, first of all, we must look at the characteristics of the drug. The packaging materials of ordinary tablets are generally polypropylene or polyethylene, which are made into white bottles. If it is a drug that is easily decomposed by light, polyester raw materials are generally selected, and color masterbatch is added to the raw materials to block light. Transparent polyester raw materials are also used for colored drugs such as candy tablets and liquid calcium, so that the shape of the drug can be seen through the bottle body, and the appearance is also better, which can increase the market attention of the drug.
The above are the characteristics of tablet bottles of different materials, and the principles for selection. Although there are certain differences in raw materials, their functions are all to maintain the safety and stability of the drug within the validity period.
