Solutions for Advanced Packaging Materials | Thermo Fisher Scientific

There’s a revolution in the materials packaging industry. The goal is to completely eliminate packaging from the “waste stream.” Companies are pledging to make packaging products that are 100% recyclable or reusable by 2025. It all starts with better chemistry and engineering.

Of all the laboratory techniques, vibrational spectroscopy affords a fast and highly accurate method to characterize polymers. Infrared spectroscopy (FTIR) was developed concurrently with the plastics and polymers industry. Essentially, it reads the molecular bonds within a material. And polymers are all about chemical bonding and molecular chains.

Polymer materials today are no longer simple PE chains, but multiphase systems comprised of semi-crystalline polymers, copolymers, polymers in solution with low molar mass compounds, physical laminates or blends, and thermoplastic precursors and composites.

Raman to the Rescue

Complementing FTIR, Raman microscopy brings several advantages in analyzing polymers, particularly for advanced packaging structures. It enables engineers and product designers to characterize multi-layer materials down to the sub-micron range with minimal sample preparation.

What can Raman microscopy do?

Confocal microscopy to understand layered materials
Identify sub-superficial defects
Identify inorganic fillers and their distribution
Differentiate polymorphs and chemical analogs
Discriminate crystalline and amorphous materials
Measure polymer density (e.g., LDPE vs. HDPE)
