Biodegradable wrappers such as onion peel wrappers are not as common
or popular as conventional ones. While onion peels are often discarded, they offer
a convenient material for wrapper development due to their health and shelf-life
benefits for food and consumers. Spoilage remains a key issue for many
consumers, prompting the need for safer, more efficient alternatives. This study
was conducted in response to growing environmental concerns, particularly the
problems posed by plastic wraps, which contribute to toxicity, waste, and clogged
drainage systems.
The researchers explored the potential of onion peels in developing
biodegradable and functional food wrappers. A mixed-method experimental design
was used, combining interviews and surveys with Home Economics students at
the Technological University of the Philippines – Manila. The study addressed
gaps in previous research, particularly around the tensile strength and food storage
capability of biodegradable materials. Results showed that 80% of participants
supported the use of onion peel wrappers as a brilliant alternative to conventional
wraps, while 20% expressed doubts due to the lack of proven long-term shelf-life
and durability. This research highlights the potential of onion peel wrappers as a
sustainable food packaging option.
