Biodegradable filling packing material production line is kind of new application of extrusion technology.

The line uses vegetable starch as main raw material. By twin screw extruder, it is processed to kind of starch-based foam material without any additive vesicant which can be fully biodegradable.
Biodegradable filling packing material can be widely used, such as packaging and filling material which can fill in the items packaging space quickly and evenly. It can be used on electrical products, precision instruments etc. since its functions of buffer and shock-absorption. What's more, it can be used as "educational sticky toys" and “DIY corn kernels” etc. After lightly wet, it can be bonded with the other materials, and create infinite styles.

Biodegradable filling packing material is applied widely since it is green, safe for children and environment biodegradable, nontoxic, lightweight, anti-static etc.

2.Raw materials:

4.Flow Chart of biodegradable foam peanuts production line:

Mixer Machine---Screw Conveyor---Twin-screw Extruder---Air Conveyor---Drying Machine

5.Technical Parameter:

6. Features:

1). frequency speed controlling with high automation and stable performance.
2). The screws are made of alloy steel and special craft, durable usage, high pressure, and the screw life is longer. Adopting the building block structure and combining willingly according to the different demands.
3). The forced lubrication system can guarantee the equipment transmission life longer.
4). The touchscreen control system can clearly view and monitor various work indicators. The auto-temperature control system makes the temperature control more direct viewing and the parameter more precise.
5). Self-cleaning. when stopping, can be cleaned without disassembling.
6). According to different screw design rates to full different technology requests.
7). This equipment has a wide material, multi-shape products, and flexible collocations. We can produce different products according to the different models and collocations.
