Heat sealing: it is a kind of blister packaging process. The paper card coated with blister oil and the blister shell are combined with the sealing machine to form a blister packaging plant in Chang'an, Dongguan.

Ultrasonic sealing: it is a kind of blister packaging process. Ultrasonic machine is used to generate ultrasonic wave, which can glue the blister and the blister together to form a double blister packaging. Unlike high-frequency sealing, ultrasonic wave can not only seal PVC and PETG materials, but also PET materials, and there is no electromagnetic damage to the packaged products, which is especially suitable for the packaging of electronic products. The disadvantage is super Sound wave edge sealing can only be intermittent, and generally only one straight edge is sealed at a time.

High frequency sealing: it is a kind of blister packaging process. It uses a high frequency machine to produce high frequency, and glue the blister and the blister together to form a double blister packaging.

Blister packaging: a general term for using blister technology to produce plastic products and corresponding equipment to package the products. Blister packaging products include: blister shell, tray, synonyms also: vacuum cover, blister cover, etc. The main advantages of blister packaging are: saving raw and auxiliary materials, light weight, convenient transportation, good sealing performance, meeting the requirements of environmental protection and green packaging; being able to package any special-shaped products without additional cushioning materials; being transparent and visible, beautiful appearance, easy to sell, suitable for mechanized and automatic packaging, convenient for modern management, labor saving and efficiency improvement 。 The anti-static tray is made of special materials, such as blister and PP plastic. The resistance of the material surface is less than 6 times of 10 or 6 times of 10 to 11 times of 10. Main use: eliminate static electricity, and widely used in the electronic devices and products production process of turnover loading, packaging, storage and transportation. Also known as anti-static tray in the industry; the height of tray is generally less than 100mm; it is suitable for precision electronic components turnover containers. According to the requirements of electronic components of customers, there are different requirements for dimensions.
