PAPTAC C.12P

Introducing PAPTAC C.12P – Industrial Physics

PAPTAC C.12P is the recognized Canadian method for evaluating contaminants in pulp, including stickies, shives, dirt, plastics, vessel cell elements, and other unwanted materials that compromise sheet quality. The method provides a structured way to separate contaminants from fibers and visually assess what’s present in your furnish.

For mills working with recycled or mixed‑fiber streams, PAPTAC C.12P is an essential tool for understanding furnish cleanliness, reducing customer complaints, and troubleshooting process issues with real evidence.

What PAPTAC C.12P Covers

PAPTAC C.12P outlines procedures for screening pulp at low consistency to isolate and quantify contaminants. Key elements include:

• Mechanical separation of fibers from contaminants
• Low‑consistency screening to protect fiber structure
• Deposition of contaminants onto filter paper for visual evaluation
• Identification of stickies, shives, dirt, plastics, and vessel elements
• Consistent sample preparation and screening parameters

The method applies to:

• Virgin and recycled pulp
• Mechanical, chemical, and semi‑chemical pulps
• Furnish evaluation at multiple process points
• QC, troubleshooting, and contaminant‑reduction programs

PAPTAC C.12P provides a clear, standardized way to see what’s getting through your system — and where it’s coming from.

Where PAPTAC C.12P Is Used

This standard is widely used across pulp and paper operations, including:

• Recycled‑fiber mills
• Tissue, packaging, and printing‑paper producers
• Integrated mills monitoring furnish cleanliness
• Screening‑system optimization programs
• R&D and quality‑control laboratories

It supports both routine contaminant monitoring and targeted troubleshooting.

Why Contaminant Analysis Matters

Understanding what’s in your pulp is essential for:

• Reducing sheet defects and customer complaints
• Preventing downgraded product and lost production time
• Identifying sources of contamination across the process
• Improving screening efficiency and furnish cleanliness
• Supporting continuous improvement and process stability

Contaminants that slip through early often become costly problems later — PAPTAC C.12P helps you catch them before they reach the machine.

Testing solutions for PAPTAC C.12P

One product from the Industrial Physics portfolio aligns directly with PAPTAC C.12P’s focus on contaminant detection:

Technidyne Pulmac MasterScreen™ Fiber Contaminant Analyzer

The MasterScreen™ shows you exactly what’s hiding in your pulp. It mechanically separates fibers from stickies, dirt, shives, vessel cell elements, plastics, and hot melts at low consistency. Contaminants are automatically deposited onto filter paper, giving you a clear visual record of what’s in your furnish — no guesswork, no interpretation required.

When contaminants appear in your finished product, the MasterScreen™ helps you trace them back to the source. Sample anywhere in your process — digesters, refiners, cleaners, grinders, repulpers, or screening systems — and the MasterScreen™ isolates what’s getting through. The result: fewer complaints, less downgraded product, and faster troubleshooting.

Industrial Physics also provides deep knowledge resources on pulp evaluation, including guidance on standard methods such as TAPPI T 275 and broader insights into contaminant analysis to help you maximize the MasterScreen™’s performance.
