A must-read for selecting flexible packaging testing instruments and adhesive tape testing instruments

　　The rapid development of the packaging industry has led to the emergence of packaging companies like mushrooms after rain, and the industry competition has become increasingly fierce. If you want to occupy more market share in the industry competition, you must first rely on product quality. Therefore, reliable testing equipment has become an indispensable weapon for the packaging industry to ensure quality.

Many manufacturers are hesitant and ponder over 　　how to choose the most suitable testing instrument .

　　In order to enable more companies to reasonably choose suitable testing instruments, the author, based on his many years of experience in working with testing instruments, will exchange and share relevant information in the hope of providing a reference for manufacturers in the packaging industry (especially those who are preparing to use laboratories).

　　1. Examination and selection of instrument manufacturers

　　The selection of instrument manufacturers is one of the most important examination items. The manufacturer's reputation, strength, and credit rating can be examined in detail:

　　1) Business nature of the manufacturer:

　　It is necessary to determine whether the manufacturer is an instrument trader or a manufacturer, which will directly affect the speed and thoroughness of solving the subsequent after-sales problems of the product. Generally, manufacturers with R&D and production capabilities should be selected, because the products are developed by the manufacturers themselves, and various problems encountered during use can be thoroughly solved and users can obtain satisfactory technical support. In addition, if you buy products directly from the manufacturers, you can also enjoy a steady stream of follow-up services in terms of product software upgrades, etc. This can also be seen from the business license. Generally, the business scope of the trader's business license only fills in sales, without the two items of "R&D, production".

　　2) The composition of instrument manufacturers’ products and their industry expertise:

　　After checking whether the instrument manufacturer has the qualifications for R&D and production, the purchaser should also pay attention to the overall composition of its products and understand whether the instrument supplier's products are complete and comprehensive in terms of professionalism. Because the more complete the professional testing instruments are, the higher the degree of specialization of the instrument supplier is, which means that its products are more suitable for this industry.

　　3) Understand the manufacturer’s R&D capabilities:

　　Because the R&D capability of manufacturers in the instrument industry is very important, generally companies with strong R&D capabilities tend to be more competitive and can grow and consolidate better in market competition. The continued existence of manufacturers can ensure that users enjoy permanent services and the normal operation of equipment is guaranteed.

　　4) Choose a company with a good reputation in the industry:

　　This is also a very important point. Companies with good reputations must have good product quality and pay special attention to the quality of purchased accessories. In this case, this type of company will pay more attention to the appearance, practicality, and user-friendliness of the product when it comes to products of the same price.

　　Of course, we will pursue the stability of equipment and even use top-level components in pursuit of product stability. This is exactly the case. You will know the horse's strength after using the equipment for a long time. The higher its industry reputation and the higher its market share, the more it proves that its equipment can stand the test of time.

　　2. Product Examination

　　1. Performance: Testing instruments are different from general consumables. They can’t just run for three to five years. The safest way is to choose products from manufacturers with good reputation, strong professionalism and high market share. Purchasers should not pay too much attention to price, but should comprehensively analyze the cost performance.

　　2. Price: Modern enterprises are all reducing costs, so price is one of the major factors that purchasers consider. But in fact, as a testing instrument, you can't just look at its selling price, but also its subsequent use costs, quality stability and other aspects are very important parts of the overall cost: in the fierce market competition, as instrument manufacturers, they also try to adjust the price to the lowest possible, but this difference in numbers reflects the difference in quality. Different selection of accessories will of course cause price inconsistency, and of course the different options determine the continuity and stability of the instrument's operation, which in turn determines the overall cost.

　　3. Brand: The brand of testing instruments is, to a certain extent, a reflection of the market share and quality of the products. Using such products is often guaranteed. For example, in the gas chromatography industry, everyone knows Agilent, and in the adhesive and packaging testing industry, everyone knows "Yue Lian Testing Instruments".

4. Has it been used by peers? The market is the effective way to test products. The more a product is used by peers, the better the match between the instrument and the industry, and that its operation, stability, accuracy and other aspects are suitable for and meet the needs of the industry.

　　5. Multifunctional integration

　　As packaging manufacturers, we have deeply realized that the market requires more and more quality control items. At this time, if the instrument can be used for multiple purposes, it can be said to be the voice of the market. In this case, as a purchaser, you must be very cautious. Some multi-functions of some instruments are reasonable, and some are unreasonable.

　　For example, the tensile testing machine , the packaging industry needs to test many items in terms of mechanics of materials, such as tension and elongation, pressure test, tear strength, tensile stress, elastic modulus, peel (90 degree peel and 180 degree peel) strength, release force test, ring initial adhesion, etc. According to the situation of packaging industry testing instrument manufacturers, Dongguan Yuelian Testing Instrument Co., Ltd. has already achieved this by allowing an instrument to meet so many professional requirements. Through the selection of test items, it can directly complete the test in accordance with the national standard requirements for the test item, and directly print out the test report of the project. Whether it is from the project name or the test unit, the user does not need to convert.

　　It should be said that the emergence of testing instruments with multiple composite functions is a favorable thing, but this mentality 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 testing indicators. In order to expand the selling points and sales of products and cater to the mentality of customers' multi-functional needs, some instrument manufacturers have changed the tensile testing machine into a product with friction coefficient testing function. If you are not a professional in instrument making, you may still think this is a good product, but a little consideration will show that as a film tensile machine, its breaking force is generally around tens of Newtons or hundreds of Newtons. Using such a tensile machine to measure the friction force of only a few tenths of a Newton cannot guarantee the accuracy and force value resolution requirements of the friction coefficient test.

　　Conclusion

　　As the purchaser, the instrument manufacturer should be required to provide relevant information such as business license, industry users, operating license, etc. At the same time, be careful not to 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 components, so that the price cannot be too low, otherwise it is easy to feel affordable when just purchased, but regret it too late once it is used.
