Fabrication of an antimicrobial active packaging and its effect on the growth of Pseudomonas and aerobic mesophilic bacteria in chicken

Vitae, 2015
ackground: One of the aims of food packaging is to protect the product from environmental factors that can cause a reduction in quality. Surface growth of microorganism is one of the leading causes of food spoilage.

Single Versus Double Screw Extrusion: Impact on Mechanical Performance and Crack Resistance for a Virgin, Recycled, and Blended Polypropylene

Polymer Engineering &Science, EarlyView.
Schematic overview of the study approach and key findings. ABSTRACT To evaluate the influence of extrusion on material performance, three processing methods, single extrusion (1x Ex), double extrusion (2x Ex), and double screw compounding (C), were investigated for virgin polypropylene (vPP), recycled PP (rPP), and a blend containing 10% rPP (rPP10 ...

Mechano‐Optical Behavior of Uniaxially Oriented Fluoropolymer Films: Ethylene Tetrafluoroethylene Copolymer (ETFE) and Tetrafluoroethylene Hexafluoropropylene‐ Vinylidene Fluoride Terpolymer (THV)

Polymer Engineering &Science, EarlyView.
Strain‐optical time slice study and evolution of microstructure via wide and small angle X‐ray scattering patterns and AFM images for uniaxially oriented THV and ETFE films at 145°C. ABSTRACT This study investigates morphological changes during the uniaxial orientation of two fluorinated polymers, ETFE and THV.

Migration of Erucamide in Polyethylene Film

Polymer Engineering &Science, EarlyView.
Erucamide migration in polyethylene films as a function of time and temperature, evaluated by FTIR‐PAS and correlated with changes in surface morphology and contact angle. ABSTRACT Erucamide is a migratory slip agent widely used in polyethylene (PE) films for flexible packaging applications, particularly those processed on high‐speed filling and ...

Biocomposite Reinforced With Mussel Shell: Packaging Application

Polymer Engineering &Science, EarlyView.
Schematic representation of the NEUTRO.BOTTLE project concept: mussel shell waste is valorized as a mineral filler in bio‐based polyethylene (Bio‐PE), compounded into a bio‐composite, and processed into rigid packaging with potential for circular material use.

High‐Order Pressure–Volume Relationship for Simulation of Stretch and Extrusion Blow Molding Processes

Polymer Engineering &Science, EarlyView.
High‐order thermodynamically consistent pressure–volume modeling improves numerical stability and prediction accuracy in stretch and extrusion blow molding simulations. The proposed formulation captures transient pressure evolution and enables reliable thickness prediction with good agreement against experimental measurements.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Extensional Rheology and Extrusion Blow Molding of Idealized High‐Density Polyethylene/Polypropylene Blends as Model Post‐Consumer Resins

Journal of Polymer Science, EarlyView.
Compatibilization markedly improves the top‐load compression performance and structural integrity of HDPE/PP blow‐molded bottles. Neat HDPE, PP, and HDPE/PP bottles exhibit premature neck cracking at relatively low strains, whereas the compatibilized HDPE/PP/C blend sustains substantially higher loads and greater deformation without cracking ...
