3-layers Stone Paper Packing Board Illustration

Material formula: Sheet size: Applications:

PP/PE:15-25% Width:1000-1500mm Various harden packing box carboard series

Caco3:70-80% Thickness:2-4mm

Auxiliary agents:3-8%

Using high CaCO3 content (75-85%) and regular polymer as raw material, compounding and 3 layers co-extrusion by screw extruder, recombined forming the high filling composite packing board. Because of its high strength, non-deformability and good protective performance, it can provide many high-quality characteristics, such as quality preservation, water-proof and moisture-proof, mildew-proof and moth-proof, reusable and cost-reducing. It can be widely used in various kinds of container packaging for logistics transportation, providing the best green packaging scheme with high performance, high cost and high protection.

This environmental protective packing board is capable of multiple recycling, the wasted packing board can be recycled by fracturing, melting, re-pelletizing and forming again through extrusion system.

This packing board is degradable eco-friendly material at the same time, during a period time of weathering, the filler content from the packing board will completely come off and since the filler content is as much high as over 75%, the remaining cellular structure connective polymer material will become pollution-free, which means the whole packing board is naturally degradable.

Environmental Protective High filling Composite Packing Board Production Line Equipment Illustration:

The whole production line includes: Compounding extrusion system, T-die mould system, 3-layers recombined forming system, final product tempering heat treatment and cooling shaping system, fracking fixed length shearing and automatic stacking system. The main technic for this 3-layers recombining is extrusion calendering forming for the middle core layer first, and this core layer has a conical or polygonal concave and convex surfaces structure, then thermo pressing with top and bot tom layers in step, which forming a 3-layers composite material packing board.

The core extruder equipment includes parallel twin screw compounding extruder, reciprocating

compounding kneader, double rotor compounding extruder, SCP high viscosity self cleaning

reactor and large capacity devolatilizer, etc.

At the same time, based on the above main extruder, the design and manufacture of a

complete set of compounding pelletizing production line equipment and compounding

extrusion forming production line equipment can be realized. It is mainly used in the fields

of engineering plastics, modified plastics, wire and cable materials, rubber, packaging,

building medical chemical industry, chemical fiber textile, household appliance and other

industries (see the application case for details).

The existing factory area of the company is 46500 m2 (of which the parent company is

38000m2, and the subsidiary (Nanjing Cenmen) is 8500m2), The core parts and system

of the extruder are designed and manufactured by the company, such as barrel, screw,

gear box, etc. The company has advanced NC machining center, NC screw grinder,

CNC machine tool and other machining equipment. Equipped with Swiss imported

three-coordinate detector and Japanese imported spectral detector and other

advanced inspection and testing equipment. There are complete quality control means

and system from processing to testing, which fully ensure the stability and reliability of

product quality.

The extruders produced by Cenmen company are exported to nearly 40 countries, such as

Germany, Russia, belarus, Japan, Korea, Israel, Ukraine, magiddon, Iran, Thailand, Indonesia,

Brazil, India, Mexico, South Africa, etc.
