New Benchmark of High Calcium Filling, Dual Breakthrough in Cost Reduction and Efficiency｜65% Calcium Carbonate High-Calcium PP Hollow Board Extruder
Jun 25, 2026
The calcium carbonate filling rate of traditional PP hollow boards is generally lower than 50%. The limited filling capacity leads to high raw material costs, while the rigidity, heat resistance and dimensional stability of the boards cannot be upgraded, failing to meet high-standard scenarios such as high-end packaging, building protection and logistics turnover. Targeting industry pain points, we proudly launch the 65% high calcium carbonate filled PP hollow board extruder. Breaking the industry technical barriers of high filling ratio, it realizes stable mass production with high calcium formula, balancing extreme cost advantages and excellent product performance, helping plastic enterprises seize market dividends.
Equipped with a customized high-mixing extrusion system and precise temperature control technology, the machine perfectly adapts to the high-calcium formula of 65% ultra-fine calcium carbonate and 35% PP base material. It solves common industry problems under high filling ratio, including uneven material dispersion, unstable discharging, board brittleness and cracking, rough surface and large thickness deviation. The exclusive screw structure strengthens material plasticization, mixing and homogenization, enabling in-depth integration of high-proportion inorganic fillers and PP resin. It thoroughly avoids the common defects of high-calcium boards such as easy deformation, poor impact resistance and production material breakage, supporting high-speed continuous production with stable mass production performance.
In terms of cost control, the 65% ultra-high calcium carbonate filling ratio greatly reduces the consumption of virgin PP raw materials. Compared with ordinary hollow board production lines, the comprehensive raw material cost is reduced by 20%-30%, with prominent cost reduction effects in large-scale production. Meanwhile, the optimized energy consumption design realizes low-energy extrusion and low scrap rate, further cutting production costs and building a high-cost-performance profit model for enterprises.
In terms of board performance, high calcium filling endows products with stronger core competitiveness. The high-calcium hollow boards produced by this machine feature greatly improved rigidity, hardness and compression resistance as well as enhanced deformation resistance. The heat deflection temperature is effectively increased with better heat resistance, suitable for more complex working conditions. Meanwhile, it retains the core advantages of hollow boards including light weight, waterproof and moisture-proof, corrosion resistance, aging resistance, sound and heat insulation, and recyclability. It also has better printing adhesion and surface flatness, fully meeting high-standard application requirements for logistics turnover boxes, building formworks, advertising backplates, industrial packaging, fruit and vegetable packaging boxes and other scenarios.
Featuring high automation, the machine is equipped with an intelligent frequency conversion control system, realizing full-process automatic operation of feeding, plasticization, extrusion, shaping, cutting and winding. It has simple operation, low failure rate and low labor cost. It supports customized production of high-calcium PP hollow boards with different thicknesses, widths and textures, with strong flexible production capacity to adapt to multiple product categories. The whole machine has a stable, wear-resistant and durable structure with long service life and convenient maintenance, suitable for standardized and large-scale production of small, medium and large plastic enterprises.
Complying with the general trend of green production, the high-calcium and low-plastic formula reduces the consumption of petrochemical raw materials. The finished products can be crushed and recycled for secondary use with no waste gas or waste pollution, conforming to national environmental protection production standards and sustainable development concepts. It helps enterprises achieve green and compliant production and enhance core market competitiveness.
