With the rapid development of packaging industry, packaging enterprises have sprung up like bamboo shoots after a spring rain, and the accompanying peer competition has become increasingly fierce. In order to occupy more market share in the competition, excellent product quality is indispensable, so reliable testing equipment has become an essential part of the packaging industry. However, the development of flexible packaging materials in China has only been in the past 20 years. Especially in the past decade, through large-scale introduction of raw material film production equipment, printing equipment, composite equipment, etc., the production, development and use of flexible packaging materials are increasing. New products and new materials emerge in endlessly. The physical property evaluation of materials is becoming more and more important, and the test technology and various performance test method standards have also emerged. The testing of flexible packaging products is of great significance for controlling the quality of flexible packaging products, guiding production and processing, studying the physical properties and structural relationships of base materials, understanding the scope of use, and designing packaging structures.

So, what instruments should be used to detect flexible packaging? What is the purpose? Development prospect? As the name implies, flexible packaging equipment is a test equipment used in the packaging industry.

1、 By industry

1. Food packaging inspection instrument

2. Drug packaging testing instrument

3. Daily chemical packaging testing instrument

4. Chemical product packaging testing instrument

5. Medical device packaging testing instrument

2、 By test item

1. Barrier performance testing instrument

2. Physical and mechanical property test

3. Printing quality inspection

3、 Detection purpose

1. Verify the reliability of packaging materials and overall packaging

2. Find out the main factors leading to product damage

3. Reduce redundant packaging materials and provide quantitative basic data for rational packaging scheme design

4. Provide quantitative basic data for the optimal scheme design of product transportation.

4、 Test significance

1. Reduce comprehensive logistics cost for enterprises

2. To reduce the cost of materials for enterprises

3. Reduce product damage rate and economic loss

4. Reduce redundant packaging materials, rationalize packaging, and reduce packaging materials

5. Rationalize the packaging and transportation scheme and reduce the comprehensive logistics cost

6. Avoid loss of enterprise brand value and decline of potential sales in the future

7. The real damage of the product results in the damage of the enterprise brand value

8. The damage of packaging materials causes the damage to the brand value of the enterprise due to the perceived product damage.

5、 Development status

1. Technical status

The degree of automation of the flexible packaging experimental equipment has increased, the results are more accurate, and the time has been greatly shortened. For example, the high temperature resistance of the high-temperature cooking bag. In the past, many manufacturers only used household pressure cookers for testing, and the temperature, pressure, and time could not be controlled. There were too many interference factors, which greatly reduced the accuracy.

2. The number of inspection items is increasing.

With the development of food flexible packaging industry, gas packaging and modified atmosphere packaging have also been widely used and expanded to more fields (such as chemicals, pesticides, etc.), so the corresponding test items are also increasing and changing. Therefore, the barrier test should not only consider oxygen, carbon dioxide, nitrogen, but also consider organic odor.

3. The equipment is more professional.

For example, an intelligent tensile testing machine can be used for the tensile strength, elongation, tearing, peeling, heat sealing strength test, puncture force test, etc. of flexible packaging materials, and each experiment has independent professional software to truly achieve specialization and intelligence.

4. Domestic experimental equipment has made a breakthrough in technology.

6、 Future development

Establish a perfect laboratory design scheme, strengthen remote communication, and combine laboratory testing with production online testing, so as to find problems at any time and reduce the occurrence of defective products.

With the development of technology, the software function of a single instrument is more perfect and stronger.

The inspection items of flexible packaging are increasing with the market demand, such as pharmaceutical packaging materials. The next few years will be a period of rapid development of the pharmaceutical packaging industry in China. For such materials, it is necessary to increase the experimental items of dissolved substances, heavy metals, easy oxides, non-volatile substances, microbial limits, abnormal toxicity, etc.
