Active Packaging: Properties & Use Scenarios | Bioleader®

Yes there is due to the locking lid on the salad to go containers preventing any leaks that may arise in the middle of meals hence are perfect for carrying salads with dressing or any other liquids — active packaging.

Our bowls come in multiple sizes, ranging from 500ml to 1500ml (approximately 8oz to 48oz), offering flexibility for different portion needs.

Yes, our paper containers with lids for food range between 500ml and 1500ml capable of holding various meal portions — active packaging.

Recent research focuses on biodegradable, flexible sensors that can be printed directly onto molded fiber trays, paperboard, or PLA films. These include gas sensors (for O₂, CO₂, ethylene) and humidity detectors using natural polymers or metallic nanoparticles. Example: He et al., 2024 engineered a stretchable, battery-free sensor system that monitors gas changes in real time within fish packaging, linked to a colorimetric indicator patch. This technology enabled 14-day shelf life for fresh fish—double that of standard packaging—while remaining fully compostable (He et al., 2024).

The EU Packaging and Packaging Waste Regulation (PPWR, 2024/XXX) mandates: All food packaging must be designed for reuse or high-quality recycling by 2030. Traceability features (unique IDs, digital passports) are required for food contact packaging by 2025–2026. Compostable packaging must comply with EN 13432 (industrial compostability) or EN 17033 (home compostability), including validation of added active/intelligent features (OJ EU, 2024) — active packaging.
