In our daily lives, vacuum-formed trays are very common. For example, plastic trays used to hold fruits and eggs in supermarkets, as well as trays used in electronics factories to store circuit board components, are all types of vacuum-formed trays.

Vacuum-formed trays come in various colors, including black, white, blue, and transparent. Commonly used materials for vacuum-formed trays include PVC, PET, PP, PS, as well as flocked materials, gold-plated materials, and anti-static materials. They not only provide protection and enhance the appearance of products but also serve as convenient packaging for transportation and handling.

The design specifications for vacuum-formed trays mainly focus on three aspects: material requirements, shape requirements, and internal structure requirements, all of which have strict criteria.

Firstly, there are material requirements. Typically, black trays are made of PS material, while transparent trays are made of PET material. Trays made from these materials possess strong anti-static capabilities. Colored vacuum-formed trays are created by adding different pigments during the production of transparent trays.

Secondly, there are shape requirements. Due to the diverse applications of vacuum-formed trays, there is no unified requirement for their overall shape in the market. Producers and users have the freedom to design the shape of vacuum-formed trays according to their specific needs. The primary requirement for the shape of vacuum-formed trays usually pertains to the thickness of the material, which is determined based on customization requirements.

Lastly, there are internal design requirements. The internal structure of vacuum-formed trays refers to the structure used to accommodate items, such as the circular base for egg trays or various shaped compartments for electronic products. The design of these structures must be tailored to meet the buyer's requirements, ensuring maximum accommodation for their products or components. Additionally, consideration should be given to the location for item retrieval and the space on both sides. Only when all these conditions are reasonably allocated and designed, can the produced trays meet the specifications of vacuum-formed trays.
