Plastic lids are covers made from various types of plastic, designed to fit securely on containers such as bottles, jars, and food storage items. They help keep contents fresh, prevent spills, and protect against contamination. Commonly used in households and industries, plastic lids come in different shapes and sizes to accommodate various products. These lids are often made from materials like polypropylene or polyethylene, which are lightweight and durable. While convenient, plastic lids contribute to environmental concerns due to their non-biodegradable nature. Recycling programs exist to help manage plastic waste, but many lids still end up in landfills, highlighting the need for sustainable alternatives.
