With the popularity of Bluetooth, more convenient Bluetooth earphones have emerged, becoming a must-have for car owners. When driving, there is no delay in answering or making phone calls, and many friends who love sports also enjoy it very much. Because there are no longer long wires that hinder the selection of the inner tray, the common earphone packaging box inner tray is made of vacuum formed material. Of course, the characteristics of vacuum forming are also quite obvious, cheap and convenient, which can effectively protect the headphones.
But some larger brands need to find different packaging boxes and inner trays in order to differentiate their brand. Firstly, vacuum forming is not as simple as people think, in fact, it has many different materials. For example, the phone case is also made of vacuum formed but very high-end materials, such as PT and PET. Of course, some electronic cotton pads are also suitable packaging boxes for Bluetooth earphones, as their characteristics are high-end and have better protection effects. Other high-end EVA products are also good choices, but they are generally used less due to their higher prices.
