Rotary Die Scoring Stress Wave Signal Acquisition
Real-time acoustic stress wave monitoring on rotary die scoring lines detects paperboard matrix micro-cracking instantaneously, reducing convert scrap by up to 80 percent.
Cepi Recyclability Guide
Technical Framework
An industry document establishes a harmonized methodology for evaluating the recycling potential of paper-based packaging products. The cepi recyclability guide defines laboratory testing procedures that simulate standard recycling mill operations to determine if a material can be successfully reprocessed. Producers use these guidelines to assess whether specific barrier coatings or adhesives prevent the recovery of high-quality secondary fibers.
Repulpability Evaluation
Papermaking organizations demand rigorous laboratory trials to replicate industrial repulping and screening phases. Under the cepi recyclability guide, the evaluation focuses on fiber yield and the presence of sticky contaminants that disrupt paper machines. Testers measure the fraction of fiber that is recovered after a standard disintegration period.
This screening ensures that only compatible additives enter the recovery stream. Modern mills cannot tolerate persistent adhesive particles that clog forming fabrics or cause spots in the recycled paper web, making the repulpability test a necessity for new packaging designs. It provides a standardized framework that replaces diverse regional methods with a single benchmark.
Performance Threshold
Packaging designers rely on specific performance thresholds to ensure their products are compatible with common collection schemes. Compliance with the cepi recyclability guide relies on a scoring system that penalizes non-paper elements such as plastic laminates and insoluble hot-melt adhesives. These results dictate whether a finished carton receives a passing grade for circular economy requirements.
