About the Foam Lunch Box
Foam lunch box refers to tableware made of disposable expanded polystyrene plastic. The foam lunch box has the characteristics of oil resistance, water resistance, corrosion resistance, heat preservation, and heat insulation. The polystyrene plastic pellets and the blowing agent are heated together, the plastic pellets become soft, and the volume expands up to 40 times at the same time. The expanded polystyrene plastic is cooled, reheated, and shaped using molds to become lunch boxes, plastic cups, plastic dishes, and other products. An expanded polystyrene product weighs 30 times less than a regular polystyrene product of the same size. Therefore, the cost of using expanded polystyrene to make lunch boxes is greatly reduced.
PS Foam Takeaway Box Production Line
YG disposable takeaway box production line has two types semi-automatic and fully automatic. The semi-automatic lunch box production line consists of four pieces of equipment: PS foam sheet unit, automatic vacuum forming machine, pulverizer, and recycling granulator. The semi-automatic production line adds a blanking machine.
How is Takeaway Container Made?
First, use a PS sheet machine to process polystyrene particles into sheet rolls. Then place the roll of sheet material on a vacuum forming machine to form. The vacuum forming machine rolls the sheet material into foamed containers mainly through a die. The remaining scraps can be pulverized by the pulverizer and then sent to the granulating unit for recycling.
Main PS Foam Food Box Machine Introduction
PS Foam Sheet Unit
The foam sheet unit adopts the double machine series high foam sheet production process. Adding a blowing agent during the extrusion of polystyrene raw materials by using this equipment. After grinding head extrusion, foaming, cooling, shaping, pulling, and winding into the finished sheet. PS foam sheet is a new type of packaging material, which has good thermal insulation and cushioning properties and also has a pearl-like appearance and color. After vacuum forming, the PS foam sheet is made into various types of food containers such as lunch boxes, trays, dishes, etc.

Fully Automatic Vacuum Forming Machine
The automatic vacuum forming machine is a new type of thermoforming unit that integrates and cuts. This fully automatic vacuum forming machine is used in the fully automatic PS foamed lunch box production line. The semi-automatic vacuum forming machine does not have the function of cutting. The automatic vacuum forming machine adopts the man-machine interface computer touch screen control system, which is easy to operate. It has the characteristics of large forming area, convenient cutting and fast forming speed. The equipment can be used to produce a wide variety of shaped sheets. The shape of the finished product can be achieved by changing the mold.

Plastic Shredder
This plastic pulverizer is specially used for pulverizing foamed plastics. The ability to crush polystyrene foam is strong and the efficiency is high. In the PS foam lunch box production line, there is cutting of leftover and unused materials. Therefore, it needs to be pulverized by a plastic pulverizer and then put into a granulator for recycling.
Circulating Pelletizing Line
The plastic granulation recycling line is used for the recycling and granulation of high-expanded polystyrene products. The recycling granulation production line mainly includes screening, feeding, extrusion, cooling, pulling, air drying, dicing, packaging, and other processes. Plastic pellets produced by recycling granulation can be recycled to reduce waste.
