Package testing laboratories must verify compliance across multiple regulatory frameworks, from FDA 21 CFR for pharmaceutical packaging to UN 3480 for lithium battery transport. Current systems process thousands of samples daily, with testing cycles that can span 2-4 weeks per submission and require precise environmental control (±0.5°C temperature, ±2% relative humidity) throughout the evaluation period.

The core challenge lies in maintaining testing accuracy and documentation while processing high sample volumes under strict environmental parameters and varying regulatory requirements.

This page brings together solutions from recent research—including AI-driven verification systems with multilevel checks, blockchain-integrated monitoring platforms, and modular testing architectures that adapt to different material types. These and other approaches help testing facilities maintain compliance while improving throughput and documentation accuracy.

1. Cardboard Packaging with Cellulose Ester Coating for Water Resistance and Moisture Permeability

HITACHI LTD, 株式会社日立製作所, 2025

Cardboard packaging materials that are highly recyclable and have water resistance and moisture permeability, as well as a system for optimizing the production and supply of these materials. The cardboard is made by coating a cellulose ester like cellulose acetate onto the paper base. This provides water resistance without adding plastics that impair recycling. The coating weight is carefully balanced to achieve water resistance and moisture permeability. A system uses demand data, shipping destinations, and regulatory information to determine the optimal cellulose ester coating for each shipment. This reduces environmental impact by avoiding overproduction of non-compliant materials.
