Why COP Bottles Do Not Change Color After Irradiation Sterilization

 Irradiation sterilization is a critical step in pharmaceutical, medical, and food packaging industries to ensure that products are free from harmful microorganisms. While materials like glass and some plastics can change in appearance or degrade after exposure to radiation, Cyclo Olefin Polymer (COP) bottles remain remarkably stable. This stability makes COP an ideal material for sensitive applications. In this blog, we will explore why COP vials do not change color after irradiation sterilization and why they are preferred for sterile packaging solutions.

after Irradiation Sterilization

What is Irradiation Sterilization?

Irradiation sterilization uses ionizing radiation—such as gamma rays, electron beams, or X-rays—to kill bacteria, viruses, and fungi. This method is particularly effective because it penetrates deep into materials without the need for high temperatures, making it suitable for heat-sensitive products.

However, ionizing radiation can affect some materials by altering their molecular structure. For instance, certain plastics may discolor, become brittle, or lose mechanical strength. These changes can compromise product appearance and integrity, posing risks in applications that require high material performance and transparency.

What is COP?

Cyclo Olefin Polymer (COP) is a high-performance thermoplastic known for several desirable properties:

RTU(ready to use) 2ml COP vial

Optical clarity: Similar to glass, making it suitable for transparent containers.

High chemical resistance: Compatible with sensitive substances, including pharmaceuticals.

Dimensional stability: Resists deformation under varying temperatures and conditions.

Low extractables: Reduces the risk of contamination, making it ideal for medical and biological storage.

COP has become the material of choice for injectable drug containers, pre-filled syringes, diagnostic kits, and laboratory equipment, where sterility and product integrity are critical.

Why Do COP Vials Resist Color Change After Irradiation?

Stable Molecular Structure

COP is engineered with a highly stable carbon backbone. Unlike some polymers, it lacks certain chemical groups—such as aromatic rings or carbonyl groups—that are prone to reacting with radiation energy. As a result, irradiation does not trigger molecular breakdown or rearrangement that would cause discoloration.

100ml polymer vial

Resistance to Oxidation

Oxidation reactions are one of the main culprits behind color changes in irradiated materials. COP’s structure is resistant to oxidation, meaning fewer byproducts form that could affect color or transparency.

Minimal Crosslinking or Chain Scission

In many polymers, irradiation causes crosslinking (linking of molecular chains) or chain scission (breaking of chains), which can alter the material's appearance and performance. COP exhibits minimal crosslinking under radiation exposure, preserving its clarity and physical properties.

Low Additive Content

Some plastics contain additives, like dyes, stabilizers, or plasticizers, which may degrade under radiation and cause discoloration. COP typically has low or no additives, ensuring that it remains stable during sterilization.

2. Appropriate packaging form: ensure effective use

The packaging form of the desiccant is also key to its performance. Generally, the desiccant is in bag form. In the packaging of effervescent tablets, the desiccant is usually placed in a small medicine compartment on the top of the lid. This design can effectively avoid direct contact between the desiccant and the effervescent tablet, thereby preventing contamination, while ensuring that the desiccant has a long-lasting moisture absorption effect.

3. Hygroscopic performance and speed: balance stability

The hygroscopic performance of the desiccant determines whether it can effectively protect the effervescent tablets. Ideal desiccants such as silica gel and molecular sieves can quickly absorb moisture in the environment to prevent the effervescent tablets from becoming ineffective or deteriorating due to moisture. However, the desiccant's hygroscopic speed must also be moderate. Too fast hygroscopicity may cause the effervescent tablets to dry out too much, destroying their structure and solubility, while too slow hygroscopicity may not provide adequate protection. Therefore, choosing the right desiccant can achieve a good balance.

The effectiveness of effervescent tablets depends on the desiccant in their packaging. The desiccant in the effervescent tablet packaging needs to meet the standards of non-toxicity and harmlessness, have excellent hygroscopicity and appropriate hygroscopicity speed, and adopt suitable packaging forms, so as to ensure the stability and safety of the effervescent tablets during storage and use. These factors work together to provide a solid guarantee for the quality of effervescent tablets.

The Differences Between COP and COC Vials: Choosing the Right Container for Medical and Cosmetic Use

This blog will explore the differences between COP vials and COC vials to help you better understand which is the right choice for your needs.

Polymer Vial for cell and gene therapies

What Are COP and COC Vials?

Both COP and COC are types of cyclo-olefin-based plastics. These materials were developed to address the limitations of traditional glass vials, which can be fragile and susceptible to chemical interactions. COP and COC vials are used in various fields, including pharmaceuticals, cosmetic medicine, and biotechnology, to store sensitive products like injectables, drugs, and even diagnostics.

Though they share many benefits over glass vials, COP and COC vials have distinct characteristics that make them suitable for different types of applications.

Key Differences Between COP and COC Vials

1. Material Composition

The primary difference between COP and COC vials lies in their material composition:

COP (Cyclo-Olefin Polymer): COP is a pure polymer made entirely from cyclo-olefin monomers. It is created through polymerization without the use of any co-monomers, which gives it enhanced structural strength and stability.

COC (Cyclo-Olefin Copolymer): COC, on the other hand, is a copolymer, meaning it is made from two different monomers—typically a cyclo-olefin and a comonomer such as ethylene. This results in a material with slightly different properties in terms of rigidity and transparency.

2. Transparency and Optical Properties

COC Vials: One of the standout features of COC is its superior transparency and clarity. COC vials are often used when optical properties are crucial, such as in diagnostic applications where visual inspection of the product is necessary. This makes COC vials ideal when visibility of the liquid inside is important.

COP Vials: While COP vials also offer excellent transparency, they may not be as clear as COC vials. However, for most medical and cosmetic applications, COP’s transparency is more than sufficient.

3. Rigidity and Strength

COP Vials: COP has a higher structural strength than COC, making it more resistant to breakage and deformation. This makes COP vials ideal for applications where the vial may be subjected to handling stress, such as in high-usage environments or during transportation. COP's robustness is one of the reasons it is widely used in cosmetic medicine for products like Botox or hyaluronic acid fillers.

COC Vials: COC is more rigid and stiff than COP. While this might sound like an advantage, the increased stiffness can make COC vials more prone to cracking under pressure. However, in controlled environments where the vials aren’t exposed to harsh conditions, COC vials can perform well.

4. Moisture and Chemical Resistance

COP Vials: COP is known for its superior moisture resistance and chemical inertness. It does not react with the chemicals stored within, ensuring the stability of sensitive products. This property makes COP vials a go-to choice for storing pharmaceuticals and cosmetic injectables, as it preserves the product’s efficacy over long periods.

COC Vials: While COC vials also offer good chemical resistance, they are typically more permeable to moisture than COP vials. This makes COC vials less suitable for highly moisture-sensitive products, although they are still widely used in many pharmaceutical applications where moisture exposure is less of a concern.

5. Temperature Resistance

COP Vials: COP vials exhibit excellent resistance to high and low temperatures. This makes them suitable for applications requiring cold storage or even autoclaving (a sterilization process using high heat). This flexibility in temperature tolerance allows COP vials to be used across various settings, including freezing environments.

COC Vials: COC vials generally have lower thermal stability than COP. They are less suited for extreme temperature conditions, limiting their use in environments requiring freezing or high-heat sterilization.

6. Cost and Availability

COC Vials: COC vials tend to be less expensive compared to COP vials due to the manufacturing process and the materials involved. This makes them a cost-effective option for applications where their specific properties (such as clarity) are needed but where strength and moisture resistance are not critical factors.

COP Vials: COP vials, on the other hand, are typically more expensive but offer a wider range of applications due to their superior strength, temperature resistance, and chemical inertness. For high-end cosmetic injectables and pharmaceuticals, COP vials are worth the investment.

The ability to handle extreme temperatures (hot or cold)

Long-term storage of sensitive injectables (cosmetic, medical, or pharmaceutical)

Choose COC Vials if you need:

High optical clarity and transparency for visual inspections

A more cost-effective solution for non-sensitive applications

Rigid but lightweight vials in controlled environments

Conclusion

While both COP and COC vials are excellent alternatives to traditional glass vials, the right choice depends on your specific needs. COP vials offer superior strength, moisture resistance, and thermal stability, making them ideal for sensitive pharmaceutical and cosmetic applications. COC vials, on the other hand, shine in applications that require high transparency and a more cost-effective solution.

By understanding the differences between COP and COC vials, you can make an informed decision that ensures the safety, effectiveness, and longevity of your products.
