Medicinal caps are an important part of plastic bottles and the key to ensuring the overall tightness of the packaging. As a package that is in direct contact with drugs, the bottle cap needs to meet the following three basic requirements:
1. As a part of drug packaging, medicinal bottle caps need to ensure that the quality and composition of the drug will not undergo any form of change and pollution during the shelf life, which requires that the materials used for the caps must be safe, non-toxic and non-polluting. Secondly, the material must have good physical properties, chemical and microbial stability, will not decompose and age within the validity period, and the molecules in the material will not migrate or chemically change with the drug.
2. High cost performance and anti-counterfeiting: cost-effective materials can reduce the overall cost of packaging and save a certain amount of expenses for pharmaceutical companies. In addition, in order to prevent counterfeit and shoddy medicines from disrupting the market, it is particularly important to print anti-counterfeiting trademarks on the lids, so the lids must meet this processability.
3. Ease of transportation: During the circulation of medicines, it will be affected by many factors such as climate, environment, and transportation methods. Unqualified medicine packaging, especially the poor sealing of the lid, can easily lead to deterioration or contamination of medicines. Therefore, the cover must have certain heat resistance, cold resistance, barrier property, and drop resistance, in order to avoid the influence of temperature, humidity and various external forces during the circulation process.
The above are the three basic requirements that medicinal bottle caps need to meet. These requirements are also the requirements for the overall performance of the packaging, and are the key factors for whether the medicine can be well stored.
