Full Automatic PS Foam Lunch Box/Take Away/Food Container Making Machine
The production line includes 3 units:
(1) PS foam sheet extrusion line: make PS foam sheet from raw material
(2) Automatic Vacuum Forming and Cutting Integrated Machine: make PS sheet to finished products, such as PS foam tray, PS foam box etc. (we can design mold according to customer requirements)
(3) PS Crushing and Recycling Machine: recycle waste products to granules, the can mix with new material and put into PS foam sheet extruder again.
1. 105/120 PS Foam Sheet Extrusion Line
This production line adopts double-screw foam sheet extrusion technology. PS foam sheet is a kind of new-type packing material with the features of heat preservation, safety, sanitation and good plasticity. It’s mainly used to make various types of food containers, such as lunch box, dinner trays, bowls etc. by thermoforming. It’s also can be used to make advertisement board, industrial products packing and so on. It has stable performance, big capacity, high automation and yields quality products.

2. Automatic Vacuum Forming and Cutting Machine
This forming and cutting incorporated machine designed by our company is all-powerful. The main way is vacuum forming as well as press forming and synthetical forming. It can be used for forming kinds of PS foam sheet. This machine adopt PLC control, it has group possesses reliable stability, large forming area, high production and automatic degree. This machine mainly forms the PSP material which is used to produce food container, tray, bowl, etc. Forming, cutting, stacking is done in the same machine, saving labor, improving efficient, lowing labor intensity and reducing production cost. Production process is to put foam sheet into forming machine, and product and wastage will come out from the rear part.
