Airtightness testing equipment for the food packaging industry, a new line of defense to safeguard food safety in prepared vegetable boxes

With the improvement of people's living standards, the requirements for food safety are getting higher and higher. As the first barrier between food and the outside world, the airtightness of the food packaging box is crucial. It should not only isolate the pollution and keep fresh, but also resist the erosion of the external environment and prevent the food from deteriorating and corrupting.

In this article, we will bring you an in-depth understanding of the importance of food packaging box air tightness testing technology and its latest development.

First, why should food packaging boxes be airtight?

Imagine, if the box is not tightly packed, air, dust, bacteria, etc. may easily enter, leading to food spoilage and corruption, and even cause food poisoning.

Our common food packaging boxes are made of cardboard, plastic, metal, etc. Different materials have different characteristics and face their own airtightness challenges. Especially those soft and flexible plastic packaging, not only to protect food from external contamination, but also need to maintain the freshness of the interior.

• Cardboard:The paperboard is inherently porous and prone to air permeability, so special coatings or treatment processes are required to improve air tightness.
• Plastic:The hermeticity of a plastic box depends mainly on the quality of the welding or gluing process.
• Metal:Metal boxes usually have good airtightness, but the sealing of welds or lids still needs to be tested.

traditional methods of airtightness testing.such as water testing: there are limitations such as cumbersome and inefficient operation.It is often time-consuming and difficult to meet the demands of high-volume production;

Gas checking method: Positive pressure inflation or negative pressure pumping mode may cause gas impurities to enter the product interior and cause contamination.This may lead to shorten the shelf life of food, and even jeopardize food safety, it is difficult to meet the modern food packaging industry on the demand for high quality and high efficiency.

II. Development of airtightness testing technology

In order to better meet the needs of the food packaging industry, JCGK, with its long-term accumulation of R&D and rich industry experience, has launched theJC-FD10020 Negative Pressure Quantitative Specialized Airtightness Testing InstrumentThe new technology has brought a technological revolution to the food packaging industry.

Specifically.JC-FD10020 The advantages are reflected in the following aspects:

• Safer:Adopting the combination of negative pressure and quantitative testing mode, avoiding the internal contamination of the product, suitable for food, pharmaceuticals and other products with high safety requirements.
• More efficient:Fast testing speed and high detection accuracy can meet the needs of mass production.
• Smarter:Equipped with data management software to trace test results and facilitate data analysis.
• More generic:With a variety of testing modes, it can meet the testing needs of different materials and shapes of packaging boxes.
• More practical:Simple operation, easy to get started, can quickly complete the inspection work.

Third, designed specifically for food packaging sharp tools

JC-FD10020 The core strength of the instrument is its special inspection program designed for soft and flexible boxes.The instrument is equipped with specialized fixtures that can effectively fix flexible packaging of various shapes to ensure the accuracy and consistency of the inspection process.

During the test, the operator can customize the test pressure to suit the needs of different packaged products, typically between 0kPa and -90kPa.The instrument will display real-time pressure changes to determine the leakage status of the product, allowing the operator to keep track of the detection status.

Fourth, food packaging lunch box application cases

Below is an example of an airtightness test of a packaged lunch box, and the whole process is also very simple:

1. Put in the product to be tested:Secure the box to be tested in the workholding fixture cavity.
2. Set the test parameters:This includes test pressure, detection time, etc.
3. Start the instrument:Start testing.
4. The instrument will automatically detect: The leakage of the box is displayed on the screen.
5. After the test is over:The instrument records the test data and the user can export the data for analysis.

By comparing good products with products with tiny holes (simulated leaks), theFD10020 Ability to clearly distinguish between qualified and unqualified packages. For example, in the demonstration case, the final pressure of the good product was 145 Pa, whereas the product with microporous holes showed a significantly higher value of 980 Pa, which is proof of the effectiveness and accuracy of the instrument.

In addition.FD10020 Not only are they able to perform tests thatIt also has powerful data management features. It can record detailed information about each testThe data includes time, test pressure, pass or fail, and leakage. These data can be exported via USB flash drive to generate Excel tables for further analysis and management.

In additionSupport through the integration of bar code scanning function, can also realize the product of the whole traceabilityThe quality management of the company has been greatly improved.

V. Summary

Food safety is an eternal theme. The airtightness testing technology of food packaging boxes, although little known in daily life, is one of the key links to ensure food safety.

along with FD10020 With the continuous introduction and popularization of such advanced testing instruments, we have reason to believe that food safety will be better protected in the future.JCGK will continue to innovate and improve the air tightness testing technology to protect food safety. Let consumers eat with peace of mind, confidence and comfort!
