Detection Issues With Plastic Caps

So how to reasonably control the sealing performance of plastic caps is the focus of online or offline testing for production units. For plastic anti-theft bottle caps, positive pressure sealing testers are used to test their sealing degree. However, the positive pressure sealing testers on the market directly inject compressed air into sealed containers, which inevitably leads to explosions when the containers have defects. According to experts, if a 2.5-liter cola bottle explodes at 1.2MPa, its destructive power is equivalent to 100-150 grams of explosives.
