The versatile Viking concept is one of the most convenient take-away solution available. The lids pop open with no folding required while the boxes’ tapered edges ensure strong leak-resistance – a significant advantage over conventional paperboard boxes. Two lids are available: a regular paperboard lid and a see-through lid with a plant-based PLA bioplastic window. The range can be used for hot and cold food and it is both grease and water-resistant. It is also safe to use in the microwave oven.
