How to detect the quality of PET Gold-Plated Blister?
Publish Time: 2024-09-17
As a special packaging material, the quality inspection of PET Gold-Plated Blister is very important. Here are some methods to detect the quality of PET Gold-Plated Blister.
First, it can be inspected from the appearance. Observe whether the PET surface is flat and smooth, without obvious scratches, wrinkles, bubbles and other defects. The gold-plated layer should be uniform and bright, without spots, color difference, missing plating and other phenomena. Check whether the edges are neat, without burrs and cracks. The appearance quality of the product can be preliminarily judged by naked eye observation and with the help of tools such as magnifying glasses.
Secondly, detect the adhesion of the gold-plated layer. You can use the tape sticking method, stick the tape on the gold-plated surface, and then tear it off quickly to observe whether the gold-plated layer on the tape falls off. If there is no or only a small amount of shedding, it means that the adhesion is good. In addition, you can also use the grid test method, use a knife to scratch small squares on the gold-plated surface, and then stick and tear it off with tape, and evaluate the adhesion according to the shedding of the gold-plated layer in the square.
In addition, test corrosion resistance. Immerse the PET Gold-Plated Blister sample in a specific corrosive medium, such as salt water, acid solution, etc., take it out after a certain period of time, and observe whether the gold-plated layer has corrosion, discoloration, blistering, etc. Products with good corrosion resistance can maintain good appearance and performance in harsh environments.
You can also test its dimensional accuracy. Use a measuring tool to measure the length, width, height and other dimensions of the product to ensure that it meets the design requirements. Blister products with high dimensional accuracy can better match the packaged items and improve the stability and aesthetics of the packaging.
In addition, it is also important to test the performance of PET materials. Test its tensile strength, elongation at break, hardness and other mechanical performance indicators to ensure that the material has sufficient strength and toughness. At the same time, test its water barrier, gas barrier and other properties, which are crucial for some products with high requirements for packaging sealing.
In short, through various methods such as appearance inspection, adhesion test, corrosion resistance test, dimensional accuracy measurement and material performance test, the quality of PET Gold-Plated Blister can be fully and accurately tested, providing reliable guarantee for the use and promotion of products.
