Challenges of cell therapy drugs to packaging

Cell therapy drugs usually contain protein components, which are easily adsorbed on the packaging surface, resulting in drug waste and inaccurate dosage. In addition, cell drugs need to be stored in ultra-low temperature environments (such as liquid nitrogen environments) to maintain drug activity. Therefore, packaging materials must meet the following two core requirements:

1. Low protein adsorption: avoid drug waste and ensure accurate dosage;

2. Excellent low temperature resistance: maintain stability in ultra-low temperature environments to ensure drug activity.

How do COP vials meet the needs of cell therapy drugs?

1. Low protein adsorption: COP vials have extremely low protein adsorption characteristics, which can effectively prevent drug components from being adsorbed on the packaging surface, ensuring the accuracy of drug dosage and the stability of efficacy. This feature makes it an ideal choice for protein drugs and cell therapy drugs.

2. Excellent low temperature resistance: COP vials can still maintain excellent physical and chemical stability in ultra-low temperature environments, and can withstand the extreme conditions of liquid nitrogen storage, ensuring that the activity of cell therapy drugs is not affected during storage and transportation.

Application of COP vials in the field of cell therapy

At present, COP vials have been widely used in the packaging of a variety of high-value cell therapy drugs, including:

Design and application of high-density polyethylene bottles for oral solid medicine

In pharmaceutical packaging, oral solid pharmaceutical high-density polyethylene bottles (HDPE bottles) are a common and important packaging form. Due to the characteristics of solid drugs, this type of bottle has its own unique requirements in design and material selection to ensure the quality and safety of drugs.

HDPE bottle for pills

Bottle mouth design

The bottle mouth design of oral solid pharmaceutical high-density polyethylene bottles is usually larger. This design helps to facilitate the filling and taking of drugs. The advantage of a large-diameter bottle mouth is that it can quickly and effectively fill the drug, and it is also convenient for users to operate when taking the drug. Compared with the bottle mouth of liquid drugs, the bottle mouth of solid drugs does not require particularly strict sealing, because solid drugs will not cause leakage problems due to the opening and closing of the bottle mouth.

Bottle wall thickness

The wall thickness requirements of oral solid pharmaceutical high-density polyethylene bottles are relatively loose. Since solid drugs are not affected by liquid pressure, the wall thickness of this bottle is mainly to provide sufficient mechanical strength and durability. Generally speaking, the wall thickness of solid pharmaceutical bottles can be adjusted according to actual needs to ensure the stability and durability of the bottle, but it does not need to be as high as the standard of liquid pharmaceutical bottles.

Transparency and Masterbatch Use

Solid drugs have relatively low transparency requirements for bottles because solid drugs are not directly affected by light. However, in some cases, pharmaceutical packaging companies may use HDPE bottles of different colors to meet market demand or enhance product recognition. For oral solid drugs, the color of the bottle usually does not affect the quality of the drug, but it can help users identify the drug more conveniently.

Design Optimization

The design of oral solid pharmaceutical HDPE bottles also takes convenience and humanization into consideration. For example, some bottles are designed with moisture-proof functions to protect the dryness of drugs during storage. In addition, the shape and size of the bottle are also optimized for easy storage and transportation.

In summary, the design and material selection of oral solid pharmaceutical HDPE bottles are mainly based on practicality and economy. Through reasonable bottle mouth design, appropriate wall thickness and color selection, this bottle not only ensures the effectiveness and safety of the drug, but also improves the convenience of use. Pharmaceutical packaging material companies can continue to innovate in these details to improve product quality and user experience.

Bubble Emission Test for Plastic Bottle Sealing

 Sealing integrity is a crucial factor in plastic bottle manufacturing, ensuring that the product inside remains protected from contamination, leakage, and environmental exposure. One of the most effective and straightforward methods for detecting leaks in plastic bottle seals is the Bubble Emission Test.

This test is widely used across industries such as pharmaceuticals, food & beverages, and cosmetics to ensure airtight seals and high-quality packaging. Below, we’ll dive into the details of the Bubble Emission Test, how it works, and why it’s an essential part of quality control in packaging.

What is the Bubble Emission Test?

The Bubble Emission Test is a non-destructive or destructive testing method used to detect leaks in sealed plastic bottles. The test works by submerging a sealed bottle in water and applying either vacuum pressure or direct air pressure to check for escaping bubbles, which indicate leaks or poor seals.

This method is particularly useful for identifying pinhole leaks, cracks, or weak seals that might not be visible to the naked eye.

How the Bubble Emission Test Works

The Bubble Emission Test is conducted using the following steps:

Step 1: Sample Preparation

Select a sealed plastic bottle from the production line.

Ensure the bottle is free from external dirt or debris that may interfere with the test results.

Step 2: Submerging the Bottle

Fill a transparent water tank or container with enough water to completely submerge the test bottle.

Place the plastic bottle into the water.

Step 3: Applying Pressure

There are two common methods to introduce air pressure into the bottle:

HDPE pill bottle

Vacuum Chamber Method

The bottle is placed inside a vacuum chamber filled with water.

A vacuum is applied to create pressure differentials, forcing air inside the bottle to escape if there is a leak.

If the seal or the bottle is compromised, air bubbles will be seen escaping from the defect location.

Direct Air Injection Method

A nozzle or probe is inserted into the bottle to pressurize it with air.

If there is a leak, air will escape through the defect, producing bubbles in the surrounding water.

Step 4: Observing Bubble Formation

If bubbles continuously escape from the sealed area or body of the bottle, it indicates a leak.

If no bubbles appear, the seal integrity is confirmed as intact.

Step 5: Recording and Analyzing Results

Bottles that fail the test are removed from the production line for further inspection.

Depending on the failure rate, production settings may need to be adjusted to improve the sealing process.

Why Use the Bubble Emission Test?

✅ Simple and Cost-Effective

Requires minimal equipment: just a water tank and a vacuum pump or air injector.

Quick and easy to perform compared to more complex testing methods.

✅ Highly Visual

The presence of bubbles provides an immediate and clear indication of leaks.

✅ Effective for Small Leaks

Detects micro-leaks and pinhole defects that might otherwise go unnoticed.

✅ Non-Destructive Option Available

If using a vacuum chamber, the test can be performed without damaging the bottle (useful for expensive pharmaceutical or cosmetic packaging).

✅ Applicable Across Industries

Pharmaceuticals: Ensures sterility of medication bottles.

Food & Beverages: Prevents spoilage due to air/moisture entry.

Cosmetics: Avoids leaks in liquid-based beauty products.

Chemical Packaging: Ensures proper containment of hazardous materials.

Whether you are in pharmaceuticals, beverages, cosmetics, or chemicals, the Bubble Emission Test is a simple yet powerful method to verify that your plastic bottles are sealed correctly and ready for the market.
