Flexible & Rigid Packaging
Deliver packaging materials that perform reliably across production, distribution, and end use.
Performance Across the Packaging Lifecycle
Chemistry Across Flexible & Rigid Packaging
From resin production through conversion, filling, transportation, retail distribution, and consumer use, the additives you choose influence packaging performance across every stage of the packaging lifecycle. Whether you produce flexible films, rigid containers, multilayer packaging, caps and closures, or recycled-content materials, you need additive technologies that improve packaging performance while supporting evolving food-contact, sustainability, and regulatory requirements.
Packaging Manufacturing Challenges
The Demands of Packaging Performance
Modern packaging manufacturing requires you to balance processing efficiency, seal integrity, clarity, consistency, compliance, and sustainability under increasingly demanding operating conditions.
Inconsistent sealing performance, contamination, material variability, and downgauging pressures can negatively affect package protection and shelf-life performance.
Food-contact requirements, additive migration concerns, NIAS scrutiny, and PFAS restrictions continue to reshape formulation and additive selection strategies.
PCR and PIR materials can introduce variability that impacts appearance, odor, processing stability, and long-term packaging performance.
Converters and processors must maintain throughput, visual consistency, and stable processing conditions while minimizing downtime and material waste.
Brand owners and retailers continue to demand recyclable packaging solutions without compromising performance, appearance, or manufacturing efficiency.
Manufacturers must maintain stable clarity, gauge control, sealability, and physical properties across changing materials and operating environments.
Technologies Built for Packaging Performance
Specialty Additives for Flexible & Rigid Packaging
To maintain consistent packaging performance under demanding operating conditions, you need additive technologies that improve processing efficiency, protect packaging integrity, and support modern manufacturing requirements. Dover offers a broad portfolio of specialty additives designed to help packaging manufacturers maintain long-term material reliability and production consistency.
- Low-Migration Stabilization Technologies: Polymeric phosphites and antioxidants help reduce degradation during processing, improve long-term packaging stability, and reduce migration risk.
- PFAS-Free Processing Aids: Processing aids improve melt flow, reduce extrusion defects, increase throughput, and support cleaner, more stable film and sheet production.
- Packaging Recycling Stabilizers: Recycling stabilizers help restore performance in PCR and PIR materials by mitigating degradation caused by multiple heat histories.
- Food-Contact Additive Technologies: Specialty additives support food-contact requirements while helping maintain packaging performance, product protection, and material consistency.
- Purging and Transition Solutions: Specialty additives help purge systems at operating temperatures, reducing maintenance downtime and minimizing material transition waste.
