Description

Stone paper extrusion line refers to a type of production equipment used to produce stone paper and similar products. The main design principle is similar to that of the Film Extrusion Line.

Stone paper extrusion line can produce synthetic paper products with an inorganic powder addition ratio of 40% to 80%. It is composed of raw material conveying treatment system, edge material recovery system, extrusion equipment, casting equipment, longitudinal stretching machine, horizontal stretching machine, winding machine, electrical system, and automatic film thickness gauge.

Stone paper is divided into PP and PE. Users can select materials and papermaking methods according to the purpose of the paper. The processing method of the stone paper extrusion line is divided into salivating stone paper/synthetic paper production line; unidirectional stretching stone paper/synthetic paper production line; and bidirectional stretching stone paper/synthetic paper production line.

 

Stone Paper Extrusion Line includes

Three parts: material handling (granulation), salivation stretching (papermaking), and coating (paper surface treatment).

China GWELL can provide complete solutions such as plant planning and layout, technical training for stone paper production personnel, stone paper extrusion line, stone paper production process, and formula for all aspects of stone paper production. We have provided many sets of stone paper turnkey projects at home and abroad, and have been widely recognized by customers.

Composition and process of stone paper extrusion line

 

The stone paper extrusion line is mainly composed of five parts: extrusion part, casting part, corona part, winding part and electric control part. Among them, the mold part and the extrusion part can be freely combined according to the requirements of users, so as to meet the different needs of our customers (markets) to the greatest extent.

The special masterbatch is produced by batching, blending and extrusion of the stone paper machine, and then through extrusion, calendering, stretching, cooling, surface treatment, coating, slitting and winding, it is the base paper. High production efficiency, good product quality, low production cost, smooth paper surface, especially suitable for printing albums and book covers, etc.

 

Introduction of stone paper products

The stone paper of the stone paper extrusion production line is a new type of material between paper and plastic, which can not only replace some traditional functional paper and professional paper, but also replace most of the traditional plastic packaging. In addition, it has the characteristics of low cost and controllable degradation, which can save users a lot of cost without causing pollution. In the Film Extrusion Line, the new environmentally friendly material stone paper industry has a wide variety of materials, product upgrades, technology upgrades, and wide application fields. It is a sunrise industry with strong vitality.

Stone paper extrusion line product features

 

  1. The stone paper production process of the stone paper extrusion line is simple, with high output and low energy consumption.
  2. It does not use plant fibers and does not cut down trees, which can save a lot of wood and protect the natural ecology.
  3. There is no need to add chemical raw materials such as strong acid, strong alkali, bleaching agent, and no waste water, waste residue and harmful gases are discharged. It is a green product.
  4. China GWELL stone paper extrusion line products have good mechanical properties, waterproof, moisture-proof, moth-proof, folding resistance, tear resistance, oil resistance, no, odorless, no pollution, stable geometric dimensions, high printing definition, good effect, and can be used After being discarded, it can be naturally degraded into powder and return to nature.
  5. Widely used in gift packaging, pharmaceutical packaging, office supplies, decorative albums and other printed products.

Features of  stone paper extrusion line

  1. It has no grains. Traditional equipment needs to granulate in advance and then produce products, while  Stone Paper Extrusion Line uses multi-component high-precision scales to produce stone paper.
  2. Screw with special mixing function and BM design.
  3. The screen changer can filter the no-need material, and the melt pump can provide stable pressure to reach the objective of even thickness.
  4. T-die adopts a special design to make plate thickness adjustment more accurate.
  5. A three-roll calendar adopts a 45-degree tilt type, which can be raised or lowered freely.
  6. Stone paper thickness control adopts screw adjustment and press wheel two-way adjustment to control plate thickness.
  7. Gwell adopts an automatic winder to reduce the manual. and has made heroic efforts at cost reduction.

 

Advantages and characteristics of stone paper

  1. Save resources: No wood or natural plant fiber is needed, and no large amount of water is used in production, especially in Iran. Because this country the wood resource is a shortage.
  2. Environmental protection is outstanding: no discharge of wastewater, waste residue, or waste gas, and the leftovers in production can be automatically recycled and recycled again or naturally degraded after processing.

GWELL a China Plastic Extruder Supplier, stone paper extrusion line product stone paper contributes to the environment, stone paper is a large amount of inorganic mineral powder completely dissolved in a small amount of non-toxic resin, the process is environmentally friendly, and it can be brittle and return to the earth after use. If the recycled paper is sent to the incinerator for incineration, a small amount of non-toxic and harmless resin will not produce black smoke or poisonous gas after incineration, and the remaining inorganic mineral powder can also return to the earth and nature.
