If a fridge freezer compartment has an airtight door seal, it may not necessarily need a plastic lining. The primary purpose of an airtight door seal is to prevent warm air from entering the compartment and cold air from escaping, helping to maintain a stable temperature inside the fridge or freezer.
The plastic lining in a fridge freezer is typically present to provide easy-to-clean and hygienic surfaces inside the compartments. It helps protect the interior from spills, leaks, and potential bacterial growth. The lining also makes it easier to remove any accidental messes and maintain a clean environment.
Without a plastic lining, spills or leaks could potentially lead to unpleasant odors, staining, or even damage to the interior components of the fridge freezer. The lining acts as an additional layer of protection against these issues, making maintenance and cleaning more convenient.
So, while an airtight door seal is essential for energy efficiency and temperature control, a plastic lining serves additional practical purposes to keep the fridge freezer clean and hygienic. However, some modern fridge freezers have advanced interior materials that are easy to clean and resist spills and stains without the need for a traditional plastic lining. Always follow the manufacturer's recommendations for care and maintenance to ensure optimal performance and longevity of your appliance.
