How to choose the testing instrument for the quality of flexible packaging

With the rapid development of packaging industry, packaging enterprises have sprung up like bamboo shoots after a spring rain, accompanied by more and more fierce competition among peers. In order to occupy more market share in the competition, we can not do without excellent product quality, so reliable testing equipment has become an essential part of the packaging industry.
In order to enable manufacturers to reasonably select the corresponding quality testing instruments, the author combines his years of working experience in testing instruments, and exchanges and shares the relevant information, so as to provide a reference basis for manufacturers in the packaging industry (especially those who are preparing for the laboratory).
How to choose the testing instrument for the quality of flexible packaging
1. Examination and selection of instrument suppliers
The selection of instrument suppliers is one of the most important examination items, which can be focused on the credibility, strength and credit of these manufacturers.
1.1 do you have the production qualification of measuring instruments
This is very important for the buyer, because if there is no production qualification, the buyer can not pass the relevant measurement certification, and the data it issues is not valid.
1.2 business nature of the manufacturer
It is necessary to determine whether the manufacturer is an instrument agent or a manufacturer, which is directly related to the rapidity and thoroughness of the follow-up after-sales problem solving. Generally, manufacturers with R & D and production capacity should be selected. Since the products are developed by the manufacturers themselves, all kinds of problems encountered in the use can be solved thoroughly, and users can obtain satisfactory technical support. Moreover, if you purchase products directly from manufacturers, you can also enjoy continuous follow-up services in product software upgrade and other aspects.
1.3 composition and industry specialization of instrument manufacturers
After checking whether the instrument manufacturer has CMC qualification, the purchaser should also pay attention to the overall composition of its products and know whether the products of the instrument supplier are complete and * * in terms of professionalism. Because the more complete the professional testing instruments, the more specialized the instrument suppliers are, that is to say, their products are more suitable for this industry. For example, packaging manufacturers need to purchase Sealing tester As a result, several suppliers have made quotations, so you can't make a decision. At this time, you need to know other products of the instrument supplier, and you can verify whether the sealing tester meets your requirements through the level of other products.
In addition, manufacturers who focus on industrial testing instruments generally have different grades of products, such as tensile machine, heat sealing instrument, friction coefficient meter and sealing tester. They have different models and grades for customers to choose from. Such enterprises are more focused and their products are often more practical.
1.4 understand the R & D capability of the manufacturer
Because in the instrument industry, the R & D capability of manufacturers is very important. Generally, enterprises with strong R & D capability are more competitive and can grow and consolidate better in the market competition. The continuous existence of manufacturers can ensure that users can enjoy long-term service, and the normal operation of equipment can be guaranteed.
1.5 choose enterprises with good reputation in the industry
This is also a very important point. Because of the large sales volume of their products, large-scale enterprises often have lower purchase costs. In this case, this type of enterprises in front of the products with the same price will pay more attention to the beauty, practicability and friendly operation of the products.
Of course, they will pursue the stability of the equipment, and even use high-quality components in order to pursue the stability of products. This is exactly what Lu Yao knows about the horsepower, and the equipment will be known after a long time. Often, the higher the enterprise's popularity in the industry and the higher the market share, it proves that its equipment can withstand the test of time.

2. Product inspection
2.1 performance
Different from the general consumables, the testing instrument can not only run for three years and five years. The safe way is to choose the products of manufacturers with good reputation, strong professionalism and high market share. The purchasing staff should not pay too much attention to the price, and should comprehensively analyze the cost performance.
2.2 price
Modern enterprises are trying to reduce costs, so the price is a major factor that buyers need to consider. But in fact, as a testing instrument, we can't just look at its price, the cost of its subsequent use and the stability of its quality are very important parts of the overall cost: in the fierce market competition, As an instrument manufacturer, they try their best to adjust the price to * low, but the difference in the number often reflects the difference in quality. The different choice of accessories will certainly lead to price inconsistency. Of course, the different options will determine the continuity and stability of the instrument operation, and all these will determine the overall cost of the detection instrument.
2.3 brand
To a certain extent, the brand of the testing instrument is a reflection of the market share and product quality of the product, and the use of such a product is often more guaranteed. For example, in the gas chromatography industry, we all know Agilent, and in the flexible packaging testing industry, we all know that "Chenchi instrument" is the same.
2.4 have you ever used it
The market is the effective way to test products. The more products are used in the same industry, the better the matching between the instrument and the industry, and the operation, stability, accuracy and other aspects are suitable and meet the needs of the industry.
2.5 multi functional integration
As packaging manufacturers are deeply aware that the market requires more and more quality control projects, and at this time, if the instrument can be used for more than one machine, it can be said that it is the call of the market. In this case, the purchaser should be quite cautious. The multi-function of some instruments is reasonable, while others are unreasonable. For example, tensile testing machine, packaging industry has to test many items in mechanics, such as breaking force and elongation, tear strength, tensile stress, modulus of elasticity, etc peel strength (90 degrees and 180 degrees), heat sealing strength and many other requirements. To make an instrument meet so many professional requirements, according to the situation of packaging industry testing instrument manufacturers, only Jinan Languang company has achieved this. Through the selection of test items, according to the requirements of national standards for the test items, the test can be completed automatically and printed directly The test report of the project, whether from the project name or the test unit, does not need to be converted by the user.
It should be said that it is a good thing that the testing instruments have multiple functions, but this psychology will also be used by some instrument manufacturers. For example, in the plastic packaging and film industry, the tensile properties and friction coefficient of materials are two basic detection indicators. In order to expand the selling point and sales volume of products, some instrument manufacturers have changed the tensile testing machine into products with friction coefficient test function to meet the multi-functional needs of customers. If you are not a professional instrument, you may think that this is a good product. However, after a little consideration, as a film tension machine, its breaking force is generally about tens or hundreds of Newtons. It is difficult to ensure the accuracy of friction coefficient test and force resolution requirements by using such a tensile machine to measure the friction force of only a few tenths of Newton.

3. Summary
As a purchaser, instrument manufacturers should be required to provide relevant measurement, industry users, business license and other information. At the same time, they should not be led by price factors, because as a testing instrument industry, in order to ensure the reliability of its quality, it is necessary to select good parts, so that the price can not be too low, otherwise it will easily appear at the time of purchase and feel affordable, Once used, I regret it again and again.
