How to reduce the production cost of PE coated paper?

Reducing the production cost of PE coated paper is an important means to enhance the competitiveness of enterprises. The following specific cost reduction measures are proposed from multiple aspects such as raw materials, production processes, equipment optimization, and management efficiency:

Raw material optimization
Choose a cost-effective substrate:
On the premise of ensuring performance, you can choose a paper with a lower price but stable quality as the substrate, such as recycled paper or low-weight paper.

Select paper with appropriate thickness and strength according to specific application requirements to avoid over-design.

Optimize the selection of PE materials:
Use low-density polyethylene (LDPE) instead of high-density polyethylene (HDPE), because LDPE is generally cheaper and has better processing performance.

Consider using recycled PE or bio-based PE (such as PE made from sugarcane) to reduce raw material costs while meeting environmental protection requirements.

Reduce PE usage:
Reduce material consumption by reducing the thickness of PE coating while ensuring that functionality is not affected. For example, reduce the coating thickness from 30 microns to 20 microns.

Use multi-layer composite technology to reduce the thickness of a single layer of PE while maintaining performance.

Process Optimization
Improve coating uniformity:
Reduce the waste of PE materials by improving the coating process. For example, optimize the temperature, pressure and speed parameters of the coating machine to avoid over-thick or over-thin coating.
Introduce an online monitoring system to monitor the coating thickness in real time and reduce the defective rate.
Reduce energy consumption:
Optimize the heating and cooling system to reduce energy consumption. For example, use energy-efficient heaters or heat recovery devices.
Increase the automation of the production line and reduce manual intervention, thereby reducing operational errors and energy consumption.
Reduce waste generation:
Improve the coating process to reduce the generation of scraps and waste. For example, optimize the cutting size to maximize material utilization.
Recycle and reuse waste, such as re-granulating scraps for production.

Equipment Upgrade and Maintenance
Optimize equipment selection:
Choose efficient and energy-saving coating equipment to reduce energy waste during equipment operation.
Invest in multifunctional equipment that can complete multiple process steps (such as coating, printing, slitting) at the same time, thereby reducing the conversion cost between processes.
Regular equipment maintenance: Regularly maintain equipment to extend its service life and reduce downtime and repair costs caused by equipment failure. Use intelligent monitoring systems to detect potential equipment problems in advance and avoid sudden failures. Production management optimization Large-scale production: Reduce fixed costs per unit product (such as equipment depreciation, labor costs, etc.) by expanding production scale. Centralized procurement of raw materials to obtain price discounts for bulk purchases. Lean production: Implement lean production concepts to reduce waste in the production process (such as time waste and material waste). Optimize production scheduling, reduce line change times and waiting time, and improve equipment utilization. Supply chain optimization: Establish long-term cooperative relationships with suppliers to ensure a stable supply of raw materials at reasonable prices. Choose suppliers with close geographical locations to reduce logistics and transportation costs. Application of innovative technologies Development of new materials: Research low-cost but high-performance alternative materials, such as the use of partially degradable materials or recycled materials, which both reduces costs and conforms to environmental protection trends. Develop functional coating technology to reduce the thickness or number of layers of PE coating, thereby reducing material costs.
Intelligent production:
Introduce Industry 4.0 technologies, such as the Internet of Things (IoT) and big data analysis, to achieve intelligent control of the production process and improve production efficiency.
Use AI algorithms to optimize production parameters and reduce trial and error costs.

Waste recovery and recycling
Waste recovery:
Recycle and reprocess waste materials (such as scraps and unqualified products) generated during the production process into raw materials to reduce the procurement cost of new materials.
Work with professional recycling companies to handle waste materials that are difficult to recycle by themselves.
Circular economy model:
Promote the recycling of PE coated paper, such as developing detachable PE coated paper for subsequent recycling.
Participate in circular economy projects within the industry and share recycling costs with other companies.

Product design optimization
Simplify product structure:
On the premise of meeting functional requirements, simplify product design as much as possible and reduce unnecessary material use. For example, reduce the number of composite layers or special coatings.
Customized production:
Customize product specifications according to customer needs to avoid over-design or functional redundancy, thereby saving material costs.

Utilization of environmental protection policies
Enjoy policy subsidies:
If an enterprise adopts environmentally friendly materials or technologies (such as bio-based PE, recyclable design), it can apply for government environmental protection subsidies or tax incentives to indirectly reduce production costs.
Carbon emission trading:
Reduce carbon emissions through energy-saving and emission reduction measures, and participate in the carbon trading market to obtain additional benefits.
