Blister trays are common in our life, such as the plastic trays used to hold fruits, eggs and other items seen in supermarkets, and the plastic trays used to hold circuit board accessories often seen in electronic factories. Today, I'd like to introduce three major constraints on the development of blister tray industry:

The commonly used sheets of blister tray include PVC, pet, PP, PS and flocking sheet, gold-plated sheet and anti-static sheet on this basis. It plays a role in protecting and beautifying products. It also has transportation pallet packaging. Pallets are used more, mainly for convenience. Design specification of blister tray the design specification of blister tray mainly has strict requirements on material, shape and internal structure.

Material requirements, usually use PS black material to make black tray and PET material to make transparent tray. Generally, pallets made of these materials have strong anti-static ability. Some colored blister trays are made by adding different pigments when making transparent trays. Then there are the requirements of shape. Due to the different uses of blister tray, there is no unified requirement for its overall shape in the market. Producers and users can produce and design the shape of blister tray according to their needs. For the shape of blister tray, only the material thickness is required, and this thickness is customized. Finally, the internal design requirements. The so-called internal structure of blister tray refers to the structure used to hold items in the tray, such as the circular chassis of egg tray and the lattices with different shapes of electronic products. The modeling design of these structures must be designed and manufactured according to the requirements of the buyer, because the produced pallet must be able to hold the buyer's products or production originals to a large extent.

In addition, there are designs of taking position and overhead position on both sides. All the above conditions are reasonably distributed and designed, and the produced pallet is the blister pallet that meets the specifications.
