In North Korea, the manufacturing of daily-use glassware has traditionally focused on basic functionality. Due to the cold continental climate, there is a significant demand for microwavable glass containers that can handle rapid heating for winter food preparation without cracking.
The local market is currently transitioning from rudimentary soda-lime glass to high-borosilicate materials. This shift is driven by a need for more durable glass food storage container options that reduce waste and maintain the nutritional value of fermented traditional foods like Kimchi.
Despite industrial constraints, there is a growing preference for hybrid storage solutions. The integration of stainless steel food storage containers with lids alongside glass sets is becoming a standard for families seeking long-term durability and airtight sealing to prevent food spoilage.
