A plant proteins-based biodegradable packaging alternative to plastic was developed based on research about spider silk which is known for its high strength and similar on the molecular level. [32] [33] Researchers at the Agricultural Research Service are looking into using dairy-based films as an alternative to petroleum-based packaging.
Bags can also be made from degradable polyethylene film or from polylactic acid (PLA), a biodegradable polymer derived from lactic acid. [20] However, most degradable bags do not readily decompose in a sealed landfill, [21] and represent a possible contaminant to plastic recycling operations. In general, biodegradable plastic bags need to be ...
Polyethylene or polythene film biodegrades naturally, albeit over a long period of time. Methods are available to make it more degradable under certain conditions of sunlight, moisture, oxygen, and composting and enhancement of biodegradation by reducing the hydrophobic polymer and increasing hydrophilic properties.
Some even offer the option to send the wrapped gifts directly to the recipient along with a personalized greeting card. Industrially manufactured gift wrapping paper is widely accessible to consumers in retail stores, usually in the form of small rolls protected by plastic packaging.
