  • how to calculate compression strength of corrugated box?
    how to calculate compression strength of corrugated box? 2020-09-25
        The compression strength of cartons is the most important quality index required by many commodity packaging. During the test, the corrugated carton is placed between two pressure plates and pressed to pressure when the carton is crushed. This is the compression strength of the carton, expressed in kn. compression strength of predetermined carton     Carton boxes require a certain degree of compression strength, because during storage and transportation after packaging, the cartons stacked in the bottom layer are under the pressure of the upper cartons. In order to avoid collapse, they must have the appropriate compression strength. Not only can the carton compressor be tested, the compression strength of the carton can be calculated by the following formula: P = KW (n-1)     Where p is the compression strength of the carton, w is the weight of the carton after packing, n is the number of stacking layers, and K is the stacking safety factor, and K is the stacking safety factor Calculate the stacking layer number n according to the stacking height h and the height of a single carton h, and N = H / h. The stacking safety factor is determined according to the number of stacking layers of the goods. According to national standards, for storage periods less than 30d, k = 1.6; for storage periods of 30d-100d, k = 1.65; for storage periods greater than 100D, K = 2.0.     Due to the influence of various factors in the production process, the final compression strength of the cartons produced with raw materials may not be completely consistent with the estimated results. Therefore, the ultimate accurate method to determine the compression strength of corrugated boxes is to test the compression strength of corrugated boxes with a carton compression tester     after constant temperature and humidity treatment. For small and medium-sized factories without testing equipment, a board can be covered on the carton, and then the same amount of weight can be stacked on the carton to roughly determine whether the compression strength of the carton meets the requirements     After the compression strength of the carton is determined according to the raw materials, the appropriate carton board and corrugated base paper should be selected to produce the corrugated carton, so as to avoid blind production and cause waste There are many formulas for calculating the compression strength of cartons based on the ring compression strength of the base paper, but the more concise and practical formula is the Kellicutt formula, which is suitable for estimating the compression strength of 0201 cartons.     Profession creates value, GBPI creates quality products! GBPI produces packaging compression testing machines, hot tack tester,heal seal strength tester, and other packaging testing instruments. Welcome to consult!

  • What are the different types of heat sealing testers
    What are the different types of heat sealing testers 2020-09-10
    The heat sealing testser is a testing instrument researched and produced for packaging heat seal strength testing. The heat sealing testser is mainly used to measure the heat sealing temperature and heat sealing time of plastic film substrates, flexible packaging composite films, coated paper and other heat sealing composite films , Heat sealing pressure and other parameters. Because the equipment is a precision laboratory instrument, it is generally used for laboratory testing applications in packaging material factories, food, medicine, quality inspection institutes, research institutions and other enterprises and institutions. Among the many items of product packaging inspection , the heat-sealing strength inspection of the packaging is an important analysis index to evaluate the sealing strength of the heat-sealed parts. This requires heat sealing tests on the products. If the heat-sealing strength is insufficient, it will cause the package to crack at the heat-sealed place, causing problems such as food and medicine leakage and contamination. Equipment classification According to the design of the heat sealing head, the heat sealing instrument can be divided into a single head heat sealing instrument and a double five-point heat sealing instrument Single head heat sealing instrument Five-point heat sealer The single-head heat-sealing instrument can conduct heat-sealing tests on flexible packaging materials at a set temperature, pressure, and time, so as to quickly and easily find the best heat-sealing process parameters of the material. As the name implies, the equipment head is designed as a single head, the lower head accurately controls the temperature, and can be controlled by the experiment temperature. The temperature control adopts P.I.D temperature control technology, which is accurate in temperature control and fast in temperature rise. The five-point heat sealing instrument can measure the heat sealing parameters of plastic film substrates, flexible packaging composite films, coated paper and other heat sealing composite films at a certain heat sealing speed, heat sealing pressure and five heat sealing temperatures. The melting point, thermal stability, fluidity and thickness of the heat-sealing materials will show different heat-sealing performance, and the sealing process parameters may vary greatly. Using this equipment can accurately and efficiently obtain the best heat sealing performance parameters. The equipment adopts the design of independent temperature control of the upper and lower heads, and the unique five independent temperature control designs of the upper head, which facilitates the high standards of temperature and test efficiency for customers during the test. The heat-sealing strength tester with ASTM F2029 developed and produced by GBPI is mainly suitable for the determination of heat-sealing temperature, heat-sealing time and heat-sealing pressure of materials such as films, composite films, PVC hard shee...

  • How does a leak tester work
    How does a leak tester work 2020-08-14
    Packaging testing is essential to ensure the integrity of the packaging development, machine setup and quality control process. How to quickly choose a suitable air tightness testing equipment has become a major problem that plagues enterprises. Guangzhou GBPI company will introduce to you the testing methods of the mainstream air tightness detectors on the market. Companies can choose the right instrument according to their needs. 1. Positive pressure detection The positive pressure method is to seal and inflate the tested equipment so that its internal pressure is higher than the external atmospheric pressure. Three methods can be used: pressure drop method judgment, water immersion detection and fixed-point detection. Judgment by pressure drop method: In the case of completely sealing all contact surfaces, inflate the product, observe the pressure change through the air tightness tester to determine the magnitude of the leakage, and then infer the leakage of the equipment, but not the leakage point Make clear positioning. Water immersion detection (bubble method detection): Inflate a certain clean gas into the equipment, when the pressure reaches the set value, immerse it in water, and judge the location and size of the leak by observing the air bubbles. It is suitable for immersing in the interior Product detection in the water can accurately determine the location of the leak. Differential pressure detection method: The compressed air (positive pressure) is accurately input into the tested product and the standard product at the same time, the inflation circuit is cut off, and the IK-ALT series air tightness detector is used to calculate, compare and analyze to obtain the tested product The pressure difference ΔP between the product and the standard product is used to determine whether the product is qualified. 2. Vacuum leak detection (negative pressure method) detection The negative pressure method is to vacuum when the equipment is sealed to make the internal pressure less than the external atmospheric pressure. Specific applications include vacuum attenuation method (dry inspection) and vacuum side leakage method (water inspection) Vacuum attenuation method: Under the condition of completely sealing all contact surfaces, directly or indirectly vacuumize the product, and analyze and read the pressure value ΔP3 through the IK-MF series air tightness detector to determine whether the product is qualified . Vacuum side leakage method: differential pressure leak test method and bubble leak test method, the product to be tested is put into the leak test box, and the vacuum is drawn on the box body to cause a pressure difference between the inside and outside of the test product. At this time, the following phenomena will occur: a) For flexible packaging and soft bottles: I. If the packaging bag bulges and remains unchanged, the packaging is intact; II. The packaging bag does not bulge or shrinks, indicating that the packaging leaks; III. The p...
