Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications

Packaging Technology and Science, EarlyView.
Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and

Life Cycle Assessment of Closed‐Loop Opaque Recycled Polyethylene Terephthalate (rPET) Bottles for UHT Milk

Packaging Technology and Science, EarlyView.
The study quantifies environmental impacts of 1 L of ultra‐high‐temperature milk bottles, comparing a 50% recycled opaque PET (rPET) bottle with 100% virgin PET bottles under closed‐loop and non‐closed‐loop recycling scenarios. Results show that 50% opaque rPET bottles outperform 100% virgin PET bottles across all impact categories, enabled by an ...

Melt strength and drawability of HDPE, LDPE and HDPE/LDPE blends

Polymer Testing, 2019
Abstract The melt strength and drawability of a low-density polyethylene (LDPE), a high-density polyethylene (HDPE) and HDPE/LDPE blends during extension flow were studied using a Rheotens test method under die extrusion temperature ranging from 160 to 200 °C and die extrusion rates varying from 9 to 36 mm/s. The results showed that the melt strength

Leveraging Life Cycle Assessment for Informing Packaging Eco‐Design and Eco‐Modulation

Sustainable Development, EarlyView.
ABSTRACT Eco‐modulation is designed to promote the adoption of eco‐design. However, in practice, its application is mostly concentrated on end‐of‐life (EoL) optimization. This study addresses the gap by proposing a framework to assess product–packaging systems as integrated units throughout the full life cycle.
