What Does Vacuum Formed Tray (vacuum Formed Packaging) Specifically Mean?

To understand what vacuum forming tray means, we must first know what vacuum forming means. Blistering is a plastic processing method that involves heating and vacuum suction of a vacuum formed sheet to attach it to the surface of a mold, followed by cooling and shaping. Blister trays, on the other hand, are a type of plastic tray produced using the vacuum forming process. They are commonly used for partition fixation, transportation, and transportation. This is because packaging using vacuum forming technology often involves molding a large area with very thin materials, which is difficult to achieve through injection molding or other methods (insufficient injection). Thin materials also result in lower costs.

Blister trays are mainly used in three areas: electronics, food, and hardware. In the electronics industry, due to different requirements, some trays need to have anti-static effects to prevent precision electronic components from being damaged due to electrostatic effects. Therefore, a type of anti-static vacuum formed tray has been extended, which has anti-static effects and can effectively protect the electronic components inside. As for the vacuum formed packaging in the food industry, if you walk into any supermarket, you can find a variety of vacuum formed food trays in the vegetable and fruit, fresh meat, and seafood areas.

As for the materials used for vacuum formed trays, PET and PVC materials are generally used in the hardware and electronics industries; There are two types of materials in the food industry, one is transparent PET material, and the other is white, black, or milky white PP material. If it is an anti-static blister tray, PET, PVC, PP, and PS materials may be used depending on the anti-static index requirements.
