Packaging

Early plastics recycling succeeded with clean, single-resin streams but struggled with contamination, weak markets, and systems not designed for scale.

Apricot shell flour improves ductility, impact strength, and compostability in injection-moldable zein bioplastics for packaging.

Just-in-time plastics processing improves efficiency, but additives, recycled content, regulatory requirements, and supply risks now necessitate selective buffering.

Carbon black pigments limit NIR sorting, raising recyclability, compliance, and cost challenges for black plastic packaging.

Bio-based coatings use plant oils, lignin, cellulose, and starch to improve sustainability, durability, adhesion, and industrial performance.

Packaging design is shifting toward tactile, emotional, and transparent experiences that build trust with younger consumers.

Microplastics can host microbial biofilms containing pathogens and antimicrobial resistance genes in aquatic environments.

Plastics in menstrual products affect hygiene, comfort, additive exposure, PFAS concerns, and environmental impact.

Researchers synthesized a cobalt aluminate pigment (CoAL2O4) that acts as both a flame retardant and colorant in polylactide (PLA).

Quantum pigments use quantum dots to create purer, brighter, and programmable color effects in plastics, coatings, and masterbatches.

Regulation is reshaping plastics investment by compressing decision cycles, raising compliance costs, and redirecting capital across the value chain.

Repeated washing, handling, and abrasion can damage reusable plastic packaging, reducing durability, cleanability, and practical service life.
