COP vial RTU no-cleaning and no-sterilization packaging solution

Jun 12 , 2025

With the increasingly stringent demand for pharmaceutical packaging materials in the pharmaceutical industry, especially in the field of high-end drugs such as biological drugs and cell drugs, higher requirements are placed on the quality, stability and safety of packaging. COP vials (cyclic olefin polymer pharmaceutical plastic bottles) have become the ideal packaging material for many pharmaceutical companies due to their excellent chemical stability, low protein adsorption and excellent low temperature resistance. In recent years, RTU wash-free and sterilization-free packaging has attracted widespread attention in the industry as an innovative solution, providing an efficient and convenient solution for pharmaceutical production.

1. Definition of RTU wash-free and sterilization-free packaging


In the traditional drug packaging process, the bottle body usually needs to be cleaned and sterilized to ensure its sterility. This process is not only time-consuming and labor-intensive, but also increases production costs and process difficulties. The wash-free and sterilization-free packaging form of COP vials, as the name implies, is directly used for filling and packaging of drugs without going through traditional cleaning and sterilization processes. This innovative method ensures the hygiene of the bottle body and the safety of the drug by using sterile raw materials and a high-standard production environment in the bottle body production process, while avoiding many links in the traditional process, thereby greatly improving production efficiency.

2. Technical advantages of RTU wash-free and sterilization-free


Save time and cost: The traditional packaging process involves multiple processes such as cleaning and sterilization, which not only consumes a lot of time, but also increases additional labor and equipment costs. The wash-free and sterilization-free COP bottle omits these links by optimizing the production process, directly provides a sterile bottle body, shortens the production cycle, and reduces the operating costs of the factory.


Improve production efficiency: With the increasingly fierce competition in the pharmaceutical market, companies have higher and higher requirements for efficiency in the production process. The application of wash-free and sterilization-free technology allows drug filling to be carried out quickly and seamlessly, avoiding delays in the cleaning and sterilization process. This enables pharmaceutical companies to increase production flexibility, respond quickly to changes in market demand, and improve overall production capacity.

Reduce the risk of drug contamination: COP vials use a sterile production environment and select raw materials that meet pharmaceutical standards to ensure that no external contamination sources are introduced during the packaging process. In the traditional cleaning and sterilization process, improper operation or aging of the equipment may still lead to microbial contamination. The wash-free and sterilization-free COP bottle reduces the risk of drug contamination and ensures the quality and safety of drugs through source control.


3. Applicable scenarios of RTU wash-free and sterilization-free packaging


Wash-free and sterilization-free COP vials are particularly suitable for drugs with extremely high packaging requirements, especially in the fields of biological drugs, cell drugs and high pH drugs. The following are several typical application scenarios:


Biological drugs and lyophilized powders: Biological drugs usually contain sensitive proteins or active ingredients, and any unnecessary contact and contamination may affect the effect of the drug. By providing aseptic packaging, it is ensured that the drug is not contaminated during storage and transportation, and its activity is retained to the maximum extent.


Cellular drugs: Cell therapy and gene therapy drugs need to be stored in a low temperature environment, and the cleanliness and sterility of the packaging materials are extremely high. The wash-free and sterilization-free packaging form can reduce the loss and contamination of drugs during low-temperature storage and transportation.


Vaccines and high pH drugs: High pH drugs are prone to react with packaging materials during storage, affecting the stability of the drug. COP vials can effectively avoid the interaction between drugs and packaging materials and ensure the efficacy of drugs due to their chemical stability and low protein adsorption characteristics.


In short, the RTU no-cleaning and no-sterilization packaging of COP vials provides a new solution for pharmaceutical companies, which can greatly improve production efficiency and reduce costs while ensuring the quality and safety of drugs. Whether in the fields of biological drugs, cell drugs or vaccines, this innovative packaging form provides great convenience for pharmaceutical companies.
