Large-Capacity Self-Heating Lunch Box | Plastic Lunch Box Factory - HongXing

Self-Heating Technology: Freedom from Microwaves
Imagine eating a hot, satisfying meal at a remote construction site, in a truck cab, or in a classroom without a microwave. This self-heating lunch box makes it possible. A simple pull of the ring activates the food-grade heating pack, raising food temperature to 70-80°C within 15 minutes. No electricity, no fire, no hot water needed. The heating process is clean, odorless, and safe—the pack can be disposed of with regular waste. This technology revolutionizes outdoor and on-the-go dining.

Massive Capacity for Real Appetites
Standard lunch boxes often leave hardworking individuals hungry. With 21.0*17.0*13.0cm dimensions and 4.6 liters of space, this self-heating lunch box delivers generous portions. The main compartment holds a full entrée with rice or noodles; the side compartment accommodates soup, vegetables, or fruit. Whether for construction workers, truck drivers, or students, one box provides a complete, satisfying meal. The wide handle ensures comfortable carrying.

Triple Safety: Materials You Can Trust
Food safety is paramount. The inner container is crafted from 304 stainless steel—corrosion-resistant, easy to clean, and odor-free. The outer shell is food-grade PP plastic, providing impact resistance and heat insulation. Silicone seals create a leak-proof barrier, preventing spills. All materials meet international food contact standards.
