A customer from Uzbekistan visited JRX in Qingdao to discuss paper production plans, target capacity, finished product specifications and available workshop space. The visit covered coating, slitting and rewinding process layout, the space needed for raw material handling and finished roll storage, and the technical information required for the next stage of project planning.

Planning a paper coating line begins with five questions: the paper to produce, base paper and finished roll specifications, required capacity, available space and utilities, and the process sections already installed. This guide explains what to prepare for each question so the equipment scope is correct before a machine model is chosen.

A process-control view of coating lines for NCR carbonless paper and coated paperboard: how the coating stack creates the copy, which line variables must stay stable, how quality checks differ between NCR sheets and board, and how to troubleshoot streaks and faint copies.

A practical guide to matching thermal paper and sublimation transfer paper to the printing application, covering how each paper forms or carries an image, which roll and sheet specifications to confirm, and how to control quality and align specifications with purchasing.

After exhibiting at Paper Middle East 2026 in Cairo, Qingdao Jieruixin Machinery And Technology Co., Ltd. held an internal review meeting on African market feedback. The team agreed to evaluate equipment prices within the context of the complete project, improve how it explains coating lines and converting equipment, and strengthen customer follow-up through short videos, articles and clearer project questions.

Qingdao Jieruixin concluded its participation in Paper Middle East & Tissue Middle East 2026 in Cairo, where it presented a high-speed thermal paper coating machine with SIEMENS PLC control, blade and air knife coating, visualized multi-zone temperature control and an anti-curling back wet coater. It also lists the three questions manufacturers should answer when planning a coating project.

A practical buyer guide to choosing a paper coating machine: define the paper product and quality targets, match the coating method to the formulation, review the complete line configuration, plan drying and factory utilities, and set acceptance criteria before comparing supplier scope, training and lifecycle support.

Thermal paper is built from a base paper and a heat-sensitive coating that normally contains a leuco dye, a color developer, a sensitizer, a binder, and functional additives. This guide explains what each chemical group does, how the components interact in one formulation, and how buyers should evaluate documents, compatibility, and supply before changing a chemical.

Coated white board paper is a multi-ply coated paperboard used for folding cartons and printed secondary packaging. This guide covers its multi-ply structure, the technical parameters that define quality, ISO test methods, printability, six common converting defects with root causes and corrective actions, and purchasing specification practice.

A practical engineering guide to industrial sand mills and horizontal wet bead mills: how agitated media grinding works, which process parameters control fineness and throughput, how to select grinding media and separators, how to troubleshoot the five most common problems, and how to validate performance in a trial instead of trusting an advertised particle-size number.
