How To Test The Sealing Of Isolation Air Cosmetic Jar?

In the field of cosmetic packaging, Isolation Air Cosmetic Jar is favored by brands and consumers for its ability to prevent cosmetics from oxidation and contamination. However, the realization of its core function depends on good sealing. Sealing is not only related to the quality and shelf life of cosmetics, but also affects the brand reputation.

 

Importance of Sealing Test for Isolation Air Cosmetic Jar

(I) Guaranteeing Product Quality

Active ingredients in cosmetics, such as vitamin C and essential oils, are very likely to undergo oxidation reactions with oxygen in the air, resulting in color changes and reduced efficacy. Good sealing can effectively isolate oxygen and prevent such situations from happening. According to research, a well-sealed isolation air cosmetic bottle can extend the antioxidant life of vitamin C-containing skin care products by 60%.

 

(II) Preventing Microbial Contamination

There are a large number of microorganisms in the air. If the cosmetic bottle is not sealed well, microorganisms can easily invade, causing product deterioration, mold, and even damage to consumers' skin. Through strict sealing testing, the risk of microbial contamination can be reduced by more than 80%, ensuring consumer safety.

 

(III) Improving Brand Reputation

Quality accidents caused by product sealing problems will seriously damage brand image and consumer trust. According to statistics, product recalls caused by packaging sealing problems will damage brand reputation and direct economic losses can reach millions of dollars. Strict control of sealing testing is a key link in maintaining brand reputation.

 

Isolation Air Cosmetic Jar Sealing Test Standards

(I) International Standards

ISO 15171-1:2006 "Packaging - Leakage Detection of Flexible Packages - Vacuum Decay Method" provides general guidelines for sealing tests and specifies methods and parameters for detecting packaging leakage in a vacuum environment. The cosmetics industry often refers to this standard and formulates specific testing indicators based on the characteristics of its own products.

 

(II) Industry Standards

The "Technical Specifications for Sealing Test of Cosmetic Packaging Containers" formulated by the Beauty Industry Association clearly requires that under a negative pressure of 20kPa, the pressure rise within 30 seconds should not exceed 2kPa, and the sealing should be considered qualified. At the same time, differentiated testing standards have been formulated for bottles of different materials and capacities.

 

(III) Enterprise Internal Control Standards

Some high-end cosmetics brands have formulated more stringent internal control standards to ensure product quality. For example, a well-known French brand requires that the pressure of its Isolation Air Cosmetic Jar should not rise by more than 1kPa within 1 minute under a negative pressure of 30kPa, which is far higher than the basic industry standards.

 

Isolation Air Cosmetic Jar Sealing Test Method

(I) Vacuum Decay Method

Test Principle: Place the Isolation Air Cosmetic Jar in a closed test chamber and evacuate to the set pressure. If the bottle leaks, outside air will infiltrate, causing the pressure in the test chamber to rise. The pressure sensor is used to monitor the pressure change to determine the sealing.

Application Case: A packaging testing agency in the United States used the vacuum decay method to test 1,000 isolated air cosmetic bottles. The detection accuracy can reach 0.1μm leakage aperture, and 32 bottles with micro-leaks were successfully detected.

Data performance: Under a negative pressure of 20kPa, the average pressure rise of qualified bottles is 0.5kPa, while the pressure rise of unqualified bottles is 5-10kPa.​

(II) Dye penetration method​
Detection principle: Inject liquid containing dye into the Isolation Air Cosmetic Jar, apply a certain pressure after sealing, if there is a leak, the dye will seep out, and the sealing can be judged by observing whether there are traces of dye on the surface of the bottle. ​
Advantages and limitations: This method is simple to operate, low cost, and can intuitively display the leak location, but it is only suitable for leak detection with larger apertures, and has poor detection effect on small leaks (less than 0.5mm). ​
Application scenario: Perform initial screening of bottles on the production line to quickly eliminate products with obvious leaks and improve detection efficiency. ​

(III) Helium mass spectrometry leak detection method​
Detection principle: Taking advantage of the small size and strong diffusion of helium molecules, helium is filled into the test chamber. If there is a leak in the Isolation Air Cosmetic Jar, helium will enter the bottle. The helium concentration in the bottle is detected by the mass spectrometer to accurately locate the leak point.​
Detection accuracy: The helium mass spectrometry leak detection method has extremely high detection accuracy, and can detect a leakage rate of 1×10⁻⁹ Pa・m³/s, and can find micron-level leak apertures. ​
Application areas: Mainly used for high-end, precision isolation air cosmetic bottle detection, such as essence bottles, luxury cream bottles, etc.

 

Sealing test equipment and technology development

(I) Automated testing equipment

At present, there are many automated sealing test equipment on the market, such as a German brand of fully automatic vacuum decay tester, which can detect 20-30 bottles per minute with a detection accuracy of 99.5%. The equipment is equipped with an intelligent recognition system that can automatically distinguish qualified and unqualified products and classify them.

 

(II) Non-destructive testing technology

Emerging non-destructive testing technologies, such as infrared thermal imaging testing, determine the sealing by detecting the temperature change on the bottle surface. When there is a leak in the bottle, the gas flow will cause local temperature abnormalities. The infrared thermal imager can capture this change and realize non-contact and rapid detection. The application of this technology in cosmetic packaging testing is gradually being promoted.

 

(III) Intelligent testing system

Some companies have introduced artificial intelligence algorithms to conduct in-depth analysis of test data. By establishing a sealing test model, the risk of product leakage can be predicted and the production process can be optimized in advance. For example, after a domestic cosmetics company applied an intelligent testing system, the product sealing failure rate dropped from 3% to 0.5%.

 

Industry data insights and case analysis​
(I) Market testing status data​
According to statistics from market research institutions, the global Isolation Air Cosmetic Jar sealing test equipment market size will reach US$850 million in 2023, with a compound annual growth rate of 7.2%. Among them, vacuum decay equipment accounts for the largest market share, reaching 45%; although the helium mass spectrometry leak detection equipment is more expensive, its market share has also reached 20%, and it is on an upward trend. ​

(II) Typical corporate cases​
L'Oreal Group: uses a combination of vacuum decay and helium mass spectrometry leak detection to conduct double testing of the isolation air cosmetic bottles of its high-end skin care products. The annual testing cost exceeds US$5 million to ensure zero defects in product sealing, effectively reducing the risk of product recalls caused by sealing problems. ​
A new domestic brand: In the early days of its business, due to neglect of sealing testing, a batch of products suffered from oxidation and deterioration in the market, and its brand reputation was damaged. Since then, the brand has invested 2 million yuan to introduce automated testing equipment to strictly control product quality, and the product repurchase rate has increased by 30%.
