Core tip: Landsea joins hands with international leaders including BASF. Guide: in Shandong Province, the experimental data can be saved through buttons in Banjiudian Town Industrial Park, Dongping County, Tai'an City, In the production workshop of Dongping Jintai Hengsheng Paper Co., Ltd., with the flying of machines, white paperboards are produced from the assembly line continuously in the production workshop of Dongping Jintai Hengsheng Paper Co., Ltd. in the industrial park of Banjiudian Town, Dongping County, Tai'an City, Shandong Province. Surprisingly, the main raw material for the production of these cardboard is the limestone that can be seen everywhere around us. Stone paper is also widely used. Now it is generally used for cold collection transportation, fruit packaging, and can replace most of the traditional wood pulp paper
1. Stone powder is strictly proportioned with specific plastics and other additives to produce various types of base paper. Dongping Jintai Hengsheng Paper Co., Ltd. is a high-tech enterprise integrating the production, sales and technical research and development of environmental friendly synthetic paper (Stone paper) and cartons. It is an innovative enterprise with independent intellectual property rights. With 3 production technology invention patents and 15 new equipment patents as technical support, the company subverts the traditional papermaking method and turns "stone papermaking" into a reality
Ligang, director of the Technology Department of Jintai Hengsheng paper industry, said in an interview with the media: "the so-called 'stone papermaking' is to grind the stone powder into 1200 mesh nano stone powder and combine it with plastic. For every 100 kg of miles, the raw material of stone powder is added to 65%."
it is understood that the raw materials for the production of "Stone paper" are limestone, coal gangue or tail slag. After preliminary crushing, grinding or calcination, the stones form nano-sized ultra-fine modified mineral powder or whitened stone powder, which is used as the main raw material for the production of stone paper
stone powder is strictly proportioned with specific plastics and other additives. After high-speed mixing and anhydrous internal mixing, different types of filling masterbatches are produced. After proportioning and process treatment, various types of base paper can be formed for the production of stone cardboard boxes
2. Application scope of stone paperboard carton products
minister Ligang explained: "its (Stone paper) advantages are moisture-proof, water-proof and corrosion resistance; secondly, it has good folding resistance, strong impact resistance and low temperature resistance; its application scope is also relatively wide. Now it is generally refrigerated product transportation, fruit packaging, and can replace most of the traditional wood pulp paper."
the stone carton and paperboard technology is supported by one-time forming stone carton and paperboard equipment, which mainly produces environmentally friendly stone carton and paperboard with a thickness of 1.3mm to 6mm. The environmental protection stone carton paperboard produced by this production process has high compressive strength, folding resistance, waterproof and integrated molding. Its process is simple, low cost and high efficiency. It is suitable for large-scale industrial production, and is suitable for the transfer and turnover packaging of fruits, vegetables, frozen seafood, industrial parts and other products
pecc/ppcc composite base paper, as a degradable and recyclable environmental protection material that can greatly reduce the price of logistics packaging surface materials such as bubble bags, such as width, thickness, diameter, area and gauge distance, is a real environmental protection material. It is mainly used in express e-commerce, vibration damping package and other products. This product can be directly applied to compound bag making, bubble machine directly follows compound, high-speed sealing bag making machine and other equipment, and has excellent market adaptability
the supporting equipment of the patented technology of tape casting and drawing mainly produces environmentally friendly stone thin paper with a thickness of 100 microns to 200 microns and environmentally friendly stone thick paper with a thickness of more than 200 microns to 400 microns. The stone paper produced by this production process has good longitudinal tensile strength. It mainly uses coated paper, labels, cards, cartons, cartons, handbags, packaging bags and postal seals
the patented three-layer coextrusion technology is matched with the technical patent of biaxial stretching utility model equipment, which mainly produces environmental friendly stone synthetic paper with a thickness of 30 μ m to 120 μ M. The environmental protection stone paper produced by this production process has good transverse tensile strength, paper softness, smoothness and ink absorption. The main sales market is positioned as waterproof paper for fruit packaging or soft lining for gift boxes
Ligang said that compared with traditional wood pulp paper, stone paper has obvious special properties, especially zero emission, no drainage, no exhaust and no slag discharge in the production process. It meets the requirements of environmental protection and energy conservation and the development direction of new materials and new energy, and has great potential and vitality in the industrialization development
"we can form a recycling system. After our products are broken, they can be processed and used again without waste water, waste gas and waste. They can be recycled indefinitely, forming a model of limited resources and unlimited utilization."
3. New green packaging item of Jintai Hengsheng paper 2 It is reported that Jintai Hengsheng paper has established cooperative relations with Haier, Hisense, golden dragon fish and other large enterprises. On the basis of stable production of phase I project, phase II project mainly focusing on technology R & D center is being implemented
on February 12, the Shandong provincial government station issued the notice on Issuing the list of major projects in 2020, announcing the list of major construction projects in 2020 and the list of major preparatory projects in 2020
among them, there are 88 major preparatory projects in Shandong Province, and one paper packaging project (Stone paper) is shortlisted, that is, the new green packaging project of Dongping Jintai Hengsheng Paper Co., Ltd
