In recent years, there has been an increase in demand for bioactive techniques in the food packaging industry. Although edible packaging is popular, it has yet to be effectively implemented into the market. Packaging made of plastics and chemicals is widely employed in the market today, posing a threat to the environment and living creatures. This research attempts to show current breakthroughs and progress in the field of biodegradable packaging. When compared to ancient packaging materials, bio-based packaging materials are safer. Sustainable biodegradable packaging materials can be made from edible films, coatings, and other bio food packaging techniques made from various biological resources. This paper discusses the important qualities and advantages of several bio-based packing materials. It is highlighted the advantages of bio-based packaging materials over synthetic packaging materials. It has been debated the importance of employing bio-based packaging to mitigate the environmental risks associated with traditional packaging technologies. Many researchers may be prompted by this study to focus on packaging reformulation options. Thus, we can attain food packing materials by considering customer's economic and sustainability aspects.

The ESCA analysis of surface silanol (Si-OH) and amino (NH,) functional groups on glass is either not possible or very ambiguous Tbese functional groups can be identified positively by d n g chemical derivatization in conjunction with ESCA. In addition to specificity, the technique also offers a significant decrease in detection limit. Tbe NH, was derivaitized using penta-fluorobenzoldehyde (PFB) and the Si-OH was silylated with tridecaflfluor0-1,1,2,2tetrahydrmrtyl-1-tricrichlor0-silane (TDFS). Quanti6cation of the NH, group can be accomplished with PFB derivatization. Only a relative comparison of the silanol group on glass can be carried out in TDFS silylation owing to the uncertainty in the completion of this reaction in the ESCA sampling depth.

XPS when used in conjunction with silylation can determine surface hydroxide. The penetration depth was studied using DRIFT and various silylation conditions. Application of this technique to many different inorganic matrices, including Si,N, , glass, silica thin film, zinc silicate lamp phosphor and AI,O,, is illustrated.
