Different manufacturing processes of plastic films lead to differences in the surface morphology of the product, which usually affects the smoothness of film when it passes through machines and equipment. Effectively control the coefficient of friction（COF) of packaging films to improve production line efficiency. coefficient of friction（COF) has always been a major difficulty in the flexible packaging industry. The coefficient of friction (COF) of packaging film production processes is an issue that film manufacturers and distributors have to grapple with every day. In order to solve this problem, film manufacturers usually use additives in the film manufacturing process to further improve the film manufacturing process, thereby controlling the friction coefficient of flexible packaging and minimizing the impact of this adverse factor.  Click here to know more about Coefficient of friction tester Coefficient of friction tester(COF tester) is used to measure the coefficient of friction of plastic films, sheets, paper and other materials when they slide on the surface of itself or other materials. It is used in quality inspection, drug inspection, scientific research, packaging, film, food, medicine, daily chemical and other industries. In order to detect changes in friction coefficient of materials under various conditions, packaging film manufacturers generally use professional friction coefficient testers as a means of detection and control.   standards:  ASTM D1894-2014, ISO 8295-2004, TAPPI 816 Therefore, it is the time for film manufacturers to find the best way to control the coefficient of friction so that direct users and end users can obtain high-quality products with large output and few failures that can continue to operate, and tailor solutions according to customer needs and actual applications. problems that need to be faced. 

Abstract Pet food is food specially provided for pets and small animals. It is a high-end animal food between human food and traditional livestock and poultry feed. Its main nutrients are protein and fat. Under the influence of a certain temperature, oxygen and moisture, it is easy to absorb moisture and agglomerate or be oxidized and decomposed by microorganisms, resulting in the loss of nutrients and even deterioration. Therefore, pet food packaging is required to have better barrier properties. GBPI uses the N530 2.0 gas transmission rate tester complied with ASTM D1434, ISO 15105-1, ISO 2556, JIS K7126-1 to test the oxygen transmission rate of dog food packaging bags sent by customers . this machine was independently developed by GBPI R&D Team. Click to See GBPI N530 2.0 Gas Transmission Rate Tester Testing Principle GBPI N530 2.0 gas transmission rate tester comply with the principle of differential pressure method. Place the processed sample between the upper and lower chambers, use a vacuum pump to evacuate the entire gas system, and then add an atmospheric pressure experimental gas to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the action of the pressure gradient, gas penetrates from the upper chamber to the lower chamber through the film. The system can calculate the gas permeability and other barrier performance parameters of the sample through the pressure changes in the lower chamber. Prepare Test Sample The dog food packaging bags provided by the customer are multi-layer co-extruded films and bags which are with PA as the main barrier function resin. The structure of sample A is PE/Tie/PA/TIE/PE, and the structure of sample B is PA/Tie/ PE/TIE/PA/Tie/PE. Testing Process (1) Cut the sample: Place the clean and pollution-free sample to be tested on the cutting table, and use a special sample cutter to cut the test sample. (2) Sample loading: Press the button to open the pneumatic chamber cover, apply a ring of sealing grease evenly on the cavity, place the filter paper in the middle of the cavity, and then place the cut sample on the cavity coated with sealing grease, then close the test chamber cover. (3) Open the control software and set experimental parameters such as test pressure and temperature. (4) In the software operation setting interface, select the measurement mode and fill in the test sample name, detection standard, test unit and other experimental information. (5) Start the test. (6) After the test is completed, the instrument pops up a prompt message indicating that the test has been completed, and automatically calculates and displays the test results. Test Results The oxygen transmission rate test results of this dog food packaging bag are: Sample A: 39.9 cm3/(m2·24h·0.1MPa), Sample B: 15.8cm3/(m2·24h·0.1MPa). Conclusion In order to ensure the quality of pet food and extend the shelf life of pet food, it is very necessary to test the oxygen transmi...

The integrity of the packaging material during the transport of the product is very important for the manufacturer. 1. Protecting products from damage: During transportation, products may be affected by various adverse factors such as extrusion, collision, vibration and humidity. If the packaging material is not strong enough or does not have good cushioning properties, the product may be damaged during transport, leading to quality problems and customer dissatisfaction. The right packaging material can provide protection and ensure that the product remains intact during transportation. 2. Enhance product image and brand value: The packaging of the product is the part that comes into contact with the customer for the first time. Good packaging can leave a good impression on the customer and enhance the image and brand value of the product. If the packaging material is damaged, dirty or unattractive, it may leave an impression of poor quality to the customer and even have a negative impact on the brand image. Keeping packaging materials in good condition is therefore essential to enhance the image of the product and the value of the brand. 3. Reduce financial losses: If products are damaged in transit, companies may have to bear additional costs such as the cost of returning, repairing or re-producing them. In addition, they may also face delays in delivery, customer complaints and damage to their reputation, which can have an impact on the sustainable operation of the business. By ensuring that packaging materials are intact during transport, these financial losses can be reduced and smooth business operations can be ensured. In summary, the integrity of packaging materials during the transport of products is of great importance to manufacturing companies. It not only protects the product and reduces damage and economic losses, but also enhances the image and brand value of the product and contributes to the sustainable development of the company. Therefore, enterprises should pay attention to the selection and quality management of packaging materials to ensure that products are effectively protected during transport. Protecting the packaging of manufactured products is an important part of ensuring that products are protected from damage during transport and storage. To ensure the quality and reliability of packaging, packaging laboratories perform various tests to assess the performance of the packaging. The following are some common packaging laboratory tests: 1. Compressive strength test: This test is used to assess the strength and stability of a package when subjected to pressure. The packaging is placed on a test machine and gradually increasing forces are applied to measure the maximum pressure it can withstand. GBPI's self-developed compression tester can Wholly automatic, auto judge crush, auto return and auto stop can be set. With built-in system, can test independently without computer.It is an essential test before shipping cartons ...
