As a fashion consumer goods, cosmetics not only need exquisite packaging, but also need to protect products during transportation or shelf life. Jinan Sanquan Zhongshi is now developing and manufacturing related cosmetic packaging testing equipment in combination with the requirements of cosmetic packaging testing and application. Cosmetic packaging box First, cosmetics transport packaging testing Cosmetics must be transported, shelf display and other links to reach the hands of consumers, you need to have good transport packaging. At present, the transportation and packaging of cosmetics are mainly corrugated boxes, and the main test indicators are the compressive strength and stacking test of the carton. 1. Carton compressive strength test: KYJ-10K, a carton compression tester developed by Sanquan Zhongshi. During the test, the corrugated box is placed between the two pressure plates of the carton compression tester, and the compression speed is set. The pressure at which the test is pressurized until the carton is crushed is the pressure resistance of the carton, which is expressed by KN. When testing the compressive strength of the carton, be sure to set the preload value (generally 220N) according to the test standard and then test. 2, carton stacking test: the carton needs to be stacked in the process of storage and transportation, in the lower carton to withstand the pressure of the upper part of the carton, in order not to collapse, must have a suitable compressive strength after stacking, so It is very important to carry out double detection of stacking and crushing force. Using the KYJ-10K carton compression tester from Sanquan Zhongshi, the built-in stacking test function can directly give the stacking test results. Second, cosmetic packaging printing quality inspection Cosmetics have a good visual aesthetic and are beautifully printed. It is more important for the detection of printing quality. At present, the conventional items for the quality inspection of cosmetic printing are the abrasion resistance (scratch resistance) and the adhesion fastness of the printing ink layer. 1. Wear resistance test: The sample was prepared by using MCJ-03 friction tester of Sanquan Zhongshi, prepared according to GB7706, and then placed on the test plane of the friction tester for fixing. 80g of clean offset paper was installed on the load block. After the number of rubs is set, the test is started (generally 40 round trips), and the print quality is evaluated by the change in density before and after the test. Generally, more than 70% is used as a condition for conformity assessment. 2. Ink adhesion fastness test: Test test of bonding ink layer bonding fastness by using disc peeling test machine print; test test of bonding ink layer bonding fastness by adhesive tape rolling machine Third, cosmetics self-adhesive label testing Self-adhesive labels are widely used in cosmetic packaging. The testing items are mainly for the adhesive performance test of self-adhesive labels (adhesive or pressure-sensitive adhesive). The main testing items are: initial adhesive properties, sticky properties, Peel strength (peeling force) three indicators. 1. Initial tack test: Take the CNY-1 initial tack tester as an example, using a bevel roll.. ball method, when the steel ball and the pressure sensitive tape sample are briefly contacted by a slight pressure between the adhesive faces, the adhesive tape pair The adhesion of the steel ball is used to test the initial tack of the sample, and the tackiness of the steel ball is used to characterize the initial tack properties of the adhesive. 2. Sticky performance: Take the CNY-2 holding tester as an example. Hang the test plate with the adhesive sample vertically and hang it on the upper and lower ends of the test stand to hang the weight of the specified weight. After a certain time, the sample is glued. The amount of displacement or the time the sample is completely detached to characterize the tackiness of the sticker. 3. Peel strength: Peel strength is an important indicator to measure the adhesive properties of self-adhesive labels. Taking the BLJ-01 electronic peeling test machine as an example, the self-adhesive label is cut into a 25 mm width with a sampling knife, and the self-adhesive label is rolled on a standard test plate with a standard press roll, and then the sample and the test plate are pre-stripped. The test plate and the pre-stripped self-adhesive label are respectively placed in the upper and lower or left and right chucks of the test intelligent electronic tensile test or the electronic peel tester. Set the test speed to 300mm/min, start the test and test, and calculate the final peel strength KN/M. Fourth, cosmetics packaging and packaging materials, other physical and mechanical indicators testing The mechanical properties of cosmetic packaging play a very important role in the packaging, processing and transportation of cosmetics. The quality of the food directly determines the safety of the food in the circulation. Summary of all test items include: tensile strength and elongation, composite film peel strength, heat seal strength, sealing and leakage, impact resistance, material surface smoothing performance and other indicators 1. Tensile strength and elongation, peel strength, heat seal strength, tear performance Tensile strength refers to the stress value of the material before it is broken. The detection can effectively solve the damage and breakage of the package caused by the external force due to the insufficient mechanical strength of the selected packaging material. Peel strength, also referred to as composite strength or composite fastness, is the adhesion between the layers in the composite film. If the adhesive strength is too low, it is extremely easy to cause problems such as leakage due to separation between layers during use of the package. Heat seal strength, also known as heat seal strength, is the strength of the seal. During the storage and transportation of the product, once the heat seal strength is too low, it may cause problems such as cracking of the heat seal and leakage of contents. To test the above-mentioned indicators, it is necessary to carry out inspection by means of a tensile testing machine. The Sanquan Zhongshi XLW (PC)-500N intelligent electronic tensile testing machine is used to prepare the samples according to the testing standards corresponding to different inspection items. Place it in the upper and lower fixtures of the tensile tester, set the test speed to 300mm/min (the tensile test can also be set to 500mm/min), and start the test to calculate the test results. Sanquan Zhongshi Intelligent Electronic Tensile Testing Machine adopts the functional menu and only needs to select different test items to complete the standard test. At the same time, for the detection of heat seal strength, the preparation of the sample is required by means of a "heat seal tester", which is also one of the commonly used equipments in the cosmetic packaging laboratory. 2, the coefficient of friction of the material The coefficient of friction of the material, that is, the smoothness of the surface of the material, is an important indicator for evaluating the smoothness of the inside and outside of the material. It is tested to ensure that it has good opening properties or that it can be smoothly transported and packaged on a high-speed production line. Use the friction coefficient meter MXS-05A according to GB10006. 1) Firstly, the sample is adjusted according to the standard, and the test surface of one sample is fixed upward and flat on the horizontal test bench. The length of the sample and the test bench should be parallel. 2) Place the test surface (63 mm × 63 mm) of the other specimen down, wrap the slider, and fix the specimen on the front and upper surfaces of the slider with tape. 3) Place the slider with the specimen fixed in the center of the specimen without impact, and make the test direction of the two specimens parallel to the sliding direction and the force measurement system is just not affected by the force. 4) Start the instrument so that the two samples move relative to each other to test the dynamic and static friction coefficient. 5. Testing of the thickness of cosmetic packaging materials Whether the thickness of the cosmetic packaging material (film or sheet) is uniform is the basis for detecting the properties of the film. The uneven thickness of the film not only affects the tensile strength and barrier properties of the film, but also affects the subsequent processing of the film. There are various methods for measuring the thickness, which are generally divided into non-contact type and contact type: non-contact type including ray, eddy current, ultrasonic, etc.; also known as mechanical thickness measurement in contact industry, which is divided into point contact type and surface Contact type. At present, laboratory testing of cosmetic film thickness uses mechanical surface contact testing, and this method is also used as a method of thickness arbitration. Use the Sanquan Zhongshi Thickness Gauge CHY-U, take the flat material on the test bench with thick test, set the time interval and the number of statistics, and start the instrument for automatic detection. The test resolution of the instrument is 0.1 micron. . Sixth, cosmetic packaging sealing and leak detection Sealing and leak detection of cosmetic packaging refers to the characteristics of the packaging bag to prevent other substances from entering or the contents from escaping. There are two methods for commonly used detection methods: 1. Water decompression method: Tested by Sanquan Zhongshi MFY-05S negative pressure seal tester. The test procedure is as follows: put appropriate amount of distilled water in the vacuum tank, put the sample into the vacuum tank and build it on the lower side of the pressure plate to completely immerse the package. Into the water; then set the vacuum pressure and time of the test, start the test, vacuum the vacuum chamber, make the internal and external pressure difference of the sample immersed in water, observe the gas escape in the sample, to determine the sealing performance of the sample ; 2, positive pressure detection method: using Sanquan Zhongshi MFY-06C positive pressure seal tester test, by applying pressure on the inner side of the package, detecting the compressive capacity, sealing degree and leakage index of the package, thereby detecting its integrity and sealing The purpose of strength. Seven, cosmetic bottle packaging testing equipment Bottle packaging is a packaging form that is used more in the packaging field now. The bottle cap locking and opening torque value are one of the process parameters of the production unit offline or online key control. Whether the torque value is suitable or not, the intermediate transportation of the product And terminal consumption has a big impact. The detection of the cap opening force and the locking force needs to be detected by the cap torque meter NLY-20.
