Quality Inspection of Package Containers Products

First, the definition of packaging quality inspection

In packaging enterprises, often prone to inspection, test and measurement mixed usage of these words . Therefore , it is first necessary to examine the definition of a clear look of the steel drum manufacturing process.

Test refers to the product of one or more characteristics of measuring, examining , measuring , and these characteristics and requirements are compared to determine their conformity activity. Inspection of human productive activity is an important part , which is intended to reveal the scientific characteristics of the product , thereby excluding those that do not meet the necessary products to ensure product quality and meet the standard requirements , as well as improve product quality and enhance the quality of management information . In industrial enterprises, all inspection activities have actually follows a complete work process .

1 understand standard requirements ; familiar with and master packaging products quality standards and test methods standards or requirements , and as a measurement or test , compare and judge basis.

2 Sampling : Determine the sample size for testing.

3 measurement or test: measuring instruments specified , testing equipment or chemical analysis instruments and standard measurement method, the value for the quantitative assessment of the quality characteristics .

4 comparison and judgment : the measurement results are compared with the standard , and whether or not qualified to make judgments .

5 . Processing: make arrangements for qualified products , such as playing the pass mark , issued by the certificate and release. Make a disposition of non-conforming products , including non-conforming product to make scrap, rework , demotion, or by another person for review , check back with the formalities disposal conclusions.

6 records feedback: the results of the test , fill in the provisions of the original records on the table , according to regulations passed to the relevant departments , quality information feedback .

With the development of the packaging industry production technology and quality management in depth, the meaning and scope of the inspection is being further extended . For example, with the implementation of statistical tests , testing has been negative becomes positive after the checks prior prevention ; verify the user is standing on the position of product quality inspection checks to ensure that users get satisfied with the quality of products ; inspection from the factory extended to outside the plant inside ...... and so on.
Measurement value is determined for the purpose of a set of operations

It is by a known amount as a standard , and other similar compared to the amount measured to determine the magnitude of the measured size. Measurement is made with the scientific method to quantitatively assess the product or parts of the technology .Called the measurement result of the measurement values. Therefore, the measurement is different from the test. Because the measurement place, is not necessarily to have a standard , but do not need to make a judgment whether or not qualified , as long as it provides a measure achieve the purpose .

Test , also known as test is to check the product features or performance measurements performed , measurement and classification activities . In Japan standard, meaning specified tests is to investigate characteristics of the product . Test as a step in the inspection process , often made ​​explicit in the test specification requirements.

Second, the importance of packaging quality inspection

Inspection of this science is the development of social productive forces and the division of labor continue to refine the inevitable result. Since the quality of packaging products increasingly attracted universal attention and care , making inspections, to give full play to the functions for testing to ensure product quality, packaging , improve economic efficiency , by the world attention. The establishment of enterprises in the packaging can be independently tested according to technical specifications , strict checks to ensure conformity of packaging products factory inspection agency . Countries have also set up inspection departments at all levels , pick loves working and competent inspection personnel to enrich them .

Inspection is a modern packaging production of objective needs , there is no test, they could not organize modern production . Modern mass production is characterized by mechanization , high degree of automation , up and down steps closely , is an extremely complex process. From the quality of the formation of the Rule , the quality is absolutely fluctuations , producing defective products is inevitable. As production control can not guarantee a fully qualified components , in order to do not put substandard raw materials , failure is not rough machining , parts failure is not assembly, product failure is not the factory , testing must be run through the whole process of production .

Modern packaging manufacturing enterprise with a large number of advanced science and technology and management methods. As the accelerated pace of production , the quality of information on the accuracy and timeliness of the increasingly high demand .Thus, by checking the quality of the information provided in the whole production is increasingly important . Inspection work as a packaging enterprise quality management is an important content , will always play an important role .

The importance of packaging inspection summed up :

1 Identification of product quality : determining whether qualified products , which meet the requirements of the standard who is qualified to receive , does not meet the standard requirements for the unqualified rejection , from the acceptance and checking .

(2) quality of feedback information : that the test results by sorting , statistics and analysis to obtain certain information, timely information feedback to the relevant departments to improve product design and quality control to provide a reliable basis .

3 supervise the production process status: Supervision and determine whether the state of the production process changes, in order to adjust to correct .

4 process capability determination : determination step processing capacity meets the requirements of quality characteristics .

5 Determine Quality grade: judgment and determine the product's quality grade .

Some packaging production enterprises due to lack of quality first thought, marketable product , they think "the emperor daughter mentality " , thereby ignoring product quality.Some packaging production enterprises due to one-sided pursuit of value , profits, so as to cause a shoddy , shoddy serious problems , hurt the country and users. In order to safeguard the interests of countries and users , enhancing packaging product quality inspection , strict quality control is very necessary.

The economic significance of inspection work , highlighted in its ensure product quality, reduce scrap loss and inspection costs. In China's packaging enterprises, professional inspectors general staffs of the enterprises accounted for 2% to 4% , and some even more. According to information on the number of inspectors than the number of workers and enterprises , the Japanese generally below 5% . European and American companies, the proportion of inspectors generally higher than Japan , some as high as 15%. Thus, the inspection work in the social importance of the production system and economic roles .

Human activities , the test has been increasingly strengthened and perfected. Production must be checked is the essential part of business management , the role has been tested in practice for people recognized and affirmed . Therefore, we can say, with the continuous development of production and scientific and technological progress , quality testing means and methods is bound to the corresponding development of more scientific . Quality inspection is bound to be continuously strengthened, improving.
