What is plastic egg tray
Blister packaging is a type of packaging that completely covers the product by heating a piece of plastic and shaping it to form a foam or pocket "blister".
Traditional blister packaging is called face-sealed blister and has a cardboard back. The plastic blister is fixed to the front of the cardboard to hold and protect the product. You can read more about the different types of blister packaging below.
Blisters can be made into any shape, for example, a uniform shape to protect a pill, or unusual shapes to protect a product that doesn't quite fit together, like the egg tray shown below.

Different types plastic egg tray
The production process of plstic egg tray is generally as follows:
First, an aluminum resin tool is used to form a heat seal bubble cover. This process can be expensive, which is why it makes the most sense to pack a fair amount of product when using blister packaging.
The back of the cardboard is printed using a special printing process that includes an adhesive. When dried, it looks and feels no different from regular printed cardboard, but the glue melts under heat and pressure, meaning the plastic bubbles can stick to it.
The blister is placed in a special part of the sealing machine called the sealing clamp. Place the product into the bubble cover and add the card.
The fixture rotates on a turntable and uses a hot metal plate.
Pressure is applied to the plate to bind the blister to the card.
The wheel rotates again and the final blister package is removed and distributed in the outer package.
