LocknLock, the company that pioneered the world’s first four-sided locking airtight container, has led innovation in kitchen lifestyles. With its focus on safe materials, outstanding functionality, and sophisticated design, it has established itself as a global leader in airtight containers. This award once again demonstrates its strong brand competitiveness.

The company offers a wide range of airtight containers made from safe and reliable materials, including Tritan, heat-resistant glass, stainless steel, and polypropylene (PP). Its product lineup includes specialized solutions such as the ‘Freezer Fit’ refrigerator container, ‘Smart Keep Fresh’ for enhanced food preservation, the ‘Baro Hanki’ microwave-ready cooking container, the premium kimchi container ‘Breathing Stainless Kimchi Container’, and the highly portable ‘To-Go Lunchbox Series’.

Recently, LocknLock has gained attention with new product launches such as ‘Fresh Protect’, which significantly reduces staining and odor retention, and the ‘Daily To-Go Lunchbox Series’, which allows users to customize meals according to their preferences and diet.

In particular, Fresh Protect features the ‘Mediguard’ mark, ensuring enhanced safety and peace of mind. It incorporates a four-sided locking airtight structure and hollow silicone seals to prevent leakage. The product is also highly durable and suitable for use in microwaves and dishwashers, making it highly versatile.

‘Mediguard’ is a proprietary LocknLock trademark applied to products made with biocompatible materials registered with the FDA DMF and certified under USP Class VI standards. The Mediguard material is also used in the bodies of the To-Go lunchbox and salad box products.
