Stone paper is a new type of environmentally friendly material, mainly made of synthetic substances such as calcium carbonate and a small amount of polyethylene (PE), which is widely used in packaging, stationery, electronic products and other fields. Stone paper blowing film production line is one of the main production equipment of this new material, in addition to stone paper rolling production line and stone paper rolling production line, each equipment has different specifications to choose from, today we want to introduce to you is what specifications are available for stone paper blowing film production line.

Stone paper is a new type of material between paper and plastic, which can replace traditional functional paper, professional paper, and most traditional plastic packaging materials. And it has the characteristics of low cost and controllable degradation, which can save users a lot of costs without causing pollution. From the perspective of replacing traditional paper, it can save a lot of forest resources for society and reduce secondary pollution generated during the papermaking process; From the perspective of replacing traditional plastic packaging materials, it can save a large amount of strategic resource oil for the country (2.3 tons of oil can be saved for every 1 ton used), and the product can degrade after use without causing secondary white pollution. The environmentally friendly new material stone paper industry has a wide range of materials, and there is a vast space for product upgrades, technological advancements, and expanded application areas. It is a highly vibrant sunrise industry.

Characteristics of Stone Paper:

The production process of stone paper is simple; Large investment, high output, low energy consumption; Not using plant fibers or cutting down trees can save a lot of wood and protect the natural ecology; It does not require the addition of strong acids, strong alkalis, bleaching agents, or other chemical raw materials, and does not discharge wastewater, waste residue, or toxic and harmful gases, making it a green and environmentally friendly product. The product has the characteristics of good mechanical performance, waterproof, moisture-proof, moth proof, folding resistant, tear resistant, oil resistant, non-toxic, odorless, pollution-free, stable geometric dimensions, high printing clarity, good effect, and can naturally degrade into powder and return to nature after use.

Types of Stone Paper:

Category 1: Degradable and environmentally friendly packaging material series products. This product is mainly used to replace traditional plastic packaging series products; There are mainly two series of industrial packaging materials and household packaging materials. Industrial packaging materials include dust covers and protective covers for electronic, household appliances, and industrial instruments and equipment products, while household packaging materials include various packaging bags, shopping bags, garbage bags, and roll up bags used in daily life. This type of product has strong social value and market advantages.
The social value lies in:

1. The product has photodegradation, oxidative degradation, and biodegradation properties. Long term use can fundamentally solve the problem of white pollution that increasingly oppresses Mother Earth;
2. Due to the extensive use of calcium carbonate, every ton of environmentally friendly packaging material used can save the country 2.3 tons of petroleum resources. The market advantage lies in the fact that consumers not only assume social and environmental responsibilities when using it, but also save 15% to 30% of usage costs.

Category 2: Environmentally friendly stone wall paper series products. Due to advantages in raw materials, production technology, and process flow, stone paper wallpaper products are the only wall paper in the world that is close to zero benzene and zero formaldehyde. The product has functional characteristics such as no harmful substances such as heavy metals, no odor, moisture resistance, flame retardancy, and antibacterial properties. Its products have made significant breakthroughs in health and environmental protection! At the same time, due to the huge cost advantage of raw materials and the promotion of the new one-stop sales and service center direct sales model, the price of environmentally friendly wall paper is 20% to 50% lower than that of similar products in the market

The third category: environmentally friendly stone paper series products. Mainly used to replace some traditional cultural paper, packaging paper, and special paper products; This type of product changes the traditional papermaking process technology, does not use wood pulp, does not require logging, does not discharge strong acids, strong alkalis, and other chemicals, and does not discharge wastewater.

The stone paper blown film production line usually consists of the following main parts:

Stone powder mixing equipment: Add raw materials such as stone powder and resin in a certain proportion to the mixing equipment for stirring and mixing, ensuring that the raw materials are fully and evenly mixed for subsequent extrusion processing.

Extruder: The extruder is the core component of the production line, responsible for heating, melting, and mixing raw materials such as calcium carbonate and polyethylene. The specifications and production capacity of extruders (such as model, screw diameter, etc.) may vary depending on the production scale.

Rolling machine: The extruded billet is rolled through a rolling machine to achieve a certain thickness and width, while adjusting the roller pressure and speed to ensure the uniformity and surface smoothness of the billet.

Mold head: The mold head is responsible for extruding and shaping the melted material into a film shape, usually using a circular or flat mold head. The design of the mold head will affect the thickness uniformity and width of the film.

Coating machine: Apply resin or other coatings on the surface of stone paper to increase its waterproof, wear-resistant and other properties. Coating machines usually use roller coating or spray coating technology.

Cooling system: The blown film process requires rapid cooling of the formed film to maintain its shape. The cooling system generally includes a cooling water tank and an air cooling device to effectively control the temperature of the film.
Traction device: The traction device is used to stably pull the cooled film to the next process. Its speed can be adjusted according to the thickness of the film and production rhythm to ensure efficient and uniform production.

Cutting and packaging: Cut the dried stone paper and customize the size and packaging according to customer needs, usually using a paper cutter or cutting machine for automatic cutting.

The production line of stone paper equipment usually adopts advanced automation control systems, which can achieve automatic control and monitoring of the production process, improve production efficiency and product quality. Stone paper, as an environmentally friendly material, has a wide range of application prospects and can be used in fields such as books, packaging, and advertising.

Stone paper blowing film production line main equipment

Specification of finished film for stone paper production line

The film thickness of stone paper is usually between 0.05mm and 0.5mm, and the specific thickness can be adjusted according to customer needs. In addition, in terms of width, the width of stone paper film is generally between 300mm and 2000mm, which can meet various production needs. Different industries have different standards for film thickness, width, strength, etc., so production lines generally have good flexibility.

Production capacity of stone paper production line

The production capacity of the stone paper blown film production line usually ranges from 50 kg/hour to 5000 kg/hour, and the specific output depends on the type of extruder, die design, raw material ratio, etc. High capacity equipment is suitable for large-scale production, while small equipment is suitable for small and medium-sized enterprises or experimental production.

The automation level of the stone paper production line

Modern stone paper blown film production lines usually have a high degree of automation, including automatic control systems, online monitoring systems, etc. This design can improve production efficiency, reduce labor costs, and ensure stable quality of finished products.
