PP lids are ideal for microwave heating due to Polypropylene's excellent heat resistance, maintaining integrity and safety at high temperatures. They prevent food from absorbing odors, preserving original flavors and aromas, making them suitable for storing and reheating strongly scented foods like fish or garlic.

Polypropylene (PP) is a versatile thermoplastic polymer used across various sectors due to its chemical resistance, heat resistance, and low cost. Key applications include industrial containers, medical tools, food packaging, automotive parts, home appliances, construction pipes, electronics components, textiles, and agricultural films. PP's properties such as high tensile strength, moisture barrier, and electrical insulation make it a preferred material in these fields.
