Consumer demands to utilize environmentally friendly packaging have led researchers to develop packaging materials from naturally derived resources. In recent years, plant protein-based films as a replacement for synthetic plastics have attracted the attention of the global food packaging industry due to their biodegradability and unique properties. Biopolymer-based films need a filler to show improved packaging properties. One of the latest strategies introduced to food packaging technology is the production of nanocomposite films which are multiphase materials containing a filler with at least one dimension less than 100 nm. This review provides the recent findings on plant-based protein films as biodegradable materials that can be combined with nanoparticles that are applicable to food packaging. Moreover, it investigates the characterization of nanocomposite plant-based protein films/edible coatings. It also briefly describes the application of plant-based protein nanocomposite films/coating on fruits/vegetables, meat and seafood products, and some other foods. The results indicate that the functional performance, barrier, mechanical, optical, thermal and antimicrobial properties of plant protein-based materials can be extended by incorporating nanomaterials. Recent reports provide a better understanding of how incorporating nanomaterials into plant protein-based biopolymers leads to an increase in the shelf life of food products during storage time.

The main purpose of this study is to produce smart and active packages with curcumin using biodegradable polymers. To fulfill this aim, two different film making methods namely electrospinning and casting were used. Firstly, to take benefit of the halochromic properties of curcumin, it was encapsulated into chitosan/PEO based nanofibers to monitor food freshness. The average diameter of the fibers was found to be between 283 ± 27 nm and 338 ± 35 nm. It was concluded that increasing the chitosan amount in na...
Preparation of antimicrobial films from agricultural biomass
Seber, Ayşe Gizem; Bakır, Ufuk; Department of Biotechnology (2010)
Mainly used food packaging materials are petro-chemical based polymers which present environmental problems since they are not biodegradable and ecologically sustainable. In this study, biodegradable biofilms are produced from xylan, extracted from cotton stalk which is an agricultural biowaste without nutritional value. Antimicrobial property was given to the biofilms with either titanium dioxide sol-gel coatings or titanium dioxide powder addition into the biofilm forming solutions. The antimicrobial acti...
Al-Ge eutectic bonding for wafer-level vacuum packaging of MEMS devices
Dimez, Bekir Gürel; Kalay, Yunus Eren; Department of Metallurgical and Materials Engineering (2022-8)
Packaging is one of the most critical processes regarding the commercialization of MEMS devices. Wafer-level packaging is both yield and cost-efficient compared to die-level packaging. Various MEMS-based devices require vacuum encapsulation, such as microbolometers and resonators. Among other bonding methods and alloy systems used for wafer-level packaging, the Al-Ge system is advantageous since it can bond wafers by coating all the metallic layers on a single wafer. This eliminates the need for additional ...
