    6 packaging laboratory tests to protect your products 2023-07-06
    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.

  • Solar backsheet water vapor barrier performance test method
    Solar backsheet water vapor barrier performance test method 2023-01-13
    Abstract: Water vapor transmission rate is an important performance index to characterize the solar backsheet's barrier performance to external water vapor (moisture), which directly affects the working condition and service life of solar cells. This paper uses the W413 2.0 infrared water vapor transmission rate tester developed by Guangzhou Biaoji Packaging Equipment Co., Ltd. to test the water vapor transmission rate of solar backsheet samples, and introduces the test standard, test process and test results for reference of major enterprises in selecting water vapor barrier testing equipment and test methods. In the field of solar photovoltaic power generation, solar backsheets play an important role. Usually, the solar backsheet is located at the outermost layer of the solar cell module's backside, thus playing a protective and supporting role for the solar cell module. The backsheet should have reliable electrical insulation, water vapor barrier, aging resistance, mechanical strength and toughness to keep the solar cell in the best working condition and maintain a service life of 25 years. Water vapor barrier performance is one of the important indicators to measure the performance of solar backsheet. If the solar backsheet has poor water vapor barrier performance, water vapor penetrating into the encapsulation system through the backsheet will affect the EVA bonding of the encapsulation film, causing the backsheet and the encapsulation film EVA to delaminate, causing the cell to be oxidized and thus seriously reducing the cell power generation efficiency and the service life of the module. As the solar cell set is placed outdoors for a long time, the humidity is greater on rainy days and water vapor has a greater impact on the solar PV module. Therefore, it is very important to conduct water vapor transmission rate test on solar backsheet to evaluate its water vapor barrier performance. 01 Testing standards The equipment used in this test is the W413 2.0 infrared method water vapor transmission rate tester developed by GBPI.

  • Testing for Migratory Substances in Pacifiers
    Testing for Migratory Substances in Pacifiers 2022-10-14
    In the production process of rubber, plastic and other products, in order to prolong the service life of the product and have good anti-oxidation, smoothness, flexibility and other properties, antioxidants, anti-blocking agents, plasticizers and other additives are often mixed. In addition to this, it is difficult to completely react the individual monomers used to prepare the product. Experiments have shown that these additives and residual monomers will slowly migrate outward in rubber, plastic and other products. When rubber and plastic products are in direct contact with food and medicine in packaging or other forms, these substances are likely to migrate. In food and medicine, food safety incidents such as "liquor plasticizer incident" and "toxic plastic wrap incident" are all related to the migration of harmful substances in packaging. Monitoring of Migratory Substances in Articles. Pacifiers are mostly used by infants and are in direct contact with the milk powder and oral cavity. The functional development of various organs of infants is not perfect. There are more migratory substances in the pacifier, which is more harmful to the baby.
