Takeaway lunch boxes come in two main types: with and without windows. Boxes with windows feature a transparent section, typically made of plastic or biodegradable material, allowing customers to see the contents without opening the box. This visibility is especially appealing for showcasing the food's presentation and is popular in delis, bakeries, and cafes. On the other hand, lunch boxes without windows provide a more discreet option, often preferred for privacy or when presentation is less critical. Both types are designed to keep food fresh and secure during transport, catering to different customer needs and preferences.
