General Overview of Stone paper production line
Stone Paper (also known as rock paper, paper from waste marble, mineral paper, or rich mineral paper) is a paper-like product
manufactured from calcium carbonate bonded with high-density polyethylene (HDPE).
Stone paper is a term that describes a number of different formulas for making paper that have one key ingredient in common: calcium
carbonate (waste stone rock, marble, and tiles) rather than tree fiber.
Stone paper, true to its name, is made primarily of calcium carbonate, one of the most common substances on the planet. It
is durable, oil and tear-resistant, and waterproof which makes it perfect for packaging.
Compared with Traditional Paper (wood pulp paper), Stone Paper has many competitive advantages.
Applications
books, journals, maps
posters, banners
tags and labels
bags
underwater notepads

Advantages
: Per ton, Stone Paper can save 20 trees, save 7480 gallons of clean water, save
6 million BTU energy, reduce 236 pounds of carbon emissions, reduce 42 pounds of liquid
waste discharge, and reduce 167 pounds of solid waste discharge.
At least reduce 30% production cost, compared with Traditional
Paper.
: Can be used as waterproof materials, such as outdoor maps, cement bags...
: After being converted into pellets, it can be used again.
Main Components of Stone paper production line

1. Granules Making Line

2. Film Casting line
The granules manufactured by the granulating machine are transported to the machine. After heating and strong pushing of the screw, the
the temperature of the raw material is raised and together with the molten PE material is extruded into a "T" type die to form a three-layer
composite sheet material, stretched by a casting roller, and adjust the thickness of the product by controlling the speed, and then cooled and
shaped by the cooling wheelset, and then flatten, visually inspect, thickness test, and static elimination, then cut off the ear materials and
wind up the finished paper.
In the high-temperature and high-pressure process environment,
calcium carbonate powder, macromolecule materials, and a variety
of process, auxiliaries are fully mixed and milled and then extruded
by screwing.

3. Surface Handling Line(Optional)
The paper is actually usable if it’s not being printed. Some packaging applications use raw stone paper for example. But if it
needs to be decorated, and the surface must be coated to make it receptive to printing inks.
This last step is where the double surface handling takes place, turning the raw material into paper and board series, named
accordingly as RPD and RBD.
