Kraft Paper Waste Recycling Machine for Paper-Plastic Separation
The recycled coated kraft paper production line separates the paper pulp from the plastic film in waste packaging materials through processes such as shredding and paper-plastic separation, providing a physical treatment solution for the resource recovery of kraft paper packaging waste. It is suitable for recycling enterprises requiring the processing of paper-plastic composite waste.
Kraft Paper Waste Recycling Machine for Paper-Plastic Separation
1. Workflow
The kraft paper waste recycling machine employs a combination of mechanical processing and paper-plastic separation. Firstly, shredding equipment cuts the waste kraft paper into smaller pieces, reducing the material size and preparing it for subsequent processing. Subsequently, through appropriate disintegration processes, the paper pulp is gradually separated from the plastic layer, after which the pulp and plastic components are recovered using corresponding separation devices.
The specific equipment configuration must be determined based on the structure of the raw material, the type of plastic, the moisture content, and the degree of contamination. For materials with a thin coating and a high paper fibre content, the focus is on improving fibre separation efficiency; for waste with a high degree of lamination or containing other impurities, the separation process requires further evaluation.
2. Key Equipment and Applications
The paper-plastic separator is one of the core pieces of equipment in the entire production line, with its primary function being to facilitate the separation of paper pulp fibres from plastic components. A well-designed equipment configuration not only affects separation efficiency but also influences subsequent pulp utilisation, plastic recovery and operating costs.
In actual production, particular attention should be paid to the following three aspects:
Raw material adaptability: Equipment should be selected based on the structure of laminated kraft paper, paper-plastic composite packaging and other plastic-containing papers; processing effectiveness cannot be judged solely by the name of the raw material.
Separation quality: Plastic residues in the pulp and the paper fibre content in the plastic fraction are both important indicators for assessing the quality of the recovered materials. It is recommended that separation effectiveness be determined through testing with actual materials.
Operating costs: In addition to the capital investment in the equipment, careful consideration should be given to electricity consumption, water usage, labour requirements, the replacement of wear-and-tear parts, and the costs associated with treating residual materials per unit of processed volume.
This type of equipment is suitable for waste plastic-coated kraft paper, paper-plastic composite packaging, and certain industrial paper packaging waste that meets the process requirements. For materials containing oil stains, food residues, adhesives, or multi-layer composite films, it should be confirmed in advance whether additional pre-treatment processes are required.
3. How to Select a Kraft Paper Waste Recycling Machine
For small and medium-sized recycling enterprises, when selecting a production line, it is not advisable to compare equipment prices alone; an assessment should also be made taking into account daily processing capacity, raw material composition, target recycled products, and factory conditions. In particular, it is necessary to confirm whether the separated pulp can meet downstream utilisation requirements, and whether the recovered plastic possesses value for further processing.
It is recommended that representative raw material samples be provided prior to procurement, and that suppliers be asked to explain the equipment configuration, designed processing capacity, actual separation results, and energy consumption test conditions. Processing capacity should be based on specific raw material types and operating conditions, rather than simply applying capacity figures from other materials.
