Vacuum insulated lunch tin takes ultimate durability as its core competitiveness, based on high-frequency use scenarios such as daily commuting, outdoor travel, campus and office. It balances thermal insulation performance and durability. From material selection, structural design to process polishing, every detail is upgraded around durability. With solid quality and outstanding anti-loss ability, it resists various losses in daily use and remains intact even after long-term use. It not only saves the trouble of frequent replacement, but also can protect every warm meal for a long time, becoming a reliable partner for carrying meals daily, and durability runs through the entire life cycle of the product.

　　Durability Highlight 1: Thickened vacuum double-layer can body, more sturdy with pressure and drop resistance. The can body is made of thickened food-grade stainless steel, creating a vacuum double-layer structure. The outer layer thickness is upgraded to 0.8mm, and the inner layer thickness is 0.6mm. The material has high density and strong toughness, with excellent pressure resistance. It can withstand daily extrusion and collision, not easy to deform or dent; after professional drop resistance test, it remains intact when dropped from a height of 1.5 meters, no damage or leakage, completely solving the pain point that ordinary lunch tins are easy to deform and damage, suitable for high-frequency carrying scenarios such as commuting and outdoor, and still maintains a neat shape after long-term use.

　　Durability Highlight 2: Vacuum sealed temperature-locking structure, durable and non-failure. Adopting integrated forming vacuum sealing technology, the connection between the can body and the can lid is seamless, matched with food-grade silicone sealing ring. The sealing ring is made of high-temperature resistant and anti-aging material, not easy to harden or fall off, and still maintains excellent sealing performance after long-term use. It not only ensures that the thermal insulation effect does not attenuate, but also prevents leakage and odor, and avoids the sealing structure from loosening due to frequent opening and closing; the vacuum interlayer is treated with high-pressure sealing, not easy to leak air, and the thermal insulation durability is long-lasting. The service life is far longer than that of ordinary single-layer lunch tins, and it can still quickly lock temperature and keep warm for a long time after long-term use.

　　Durability Highlight 3: Scratch-resistant and wear-resistant surface, long-lasting new and non-fading. The surface of the can body adopts high-temperature spray curing technology, attached with a wear-resistant and scratch-resistant coating. The coating has strong adhesion and high hardness, and is not easy to leave scratches, fade or peel off due to daily friction and slight scratches. Even after long-term carrying and repeated touching, it can still keep the can body clean and beautiful; the can lid adopts frosted non-slip design, which not only improves the grip feel, but also reduces fingerprint residue and scratch marks, balancing durability and aesthetics, and remains as new after long-term use, without worrying about surface wear affecting the appearance.

　　Durability Highlight 4: Detailed reinforcement technology, full anti-loss ability. The can mouth adopts thickened crimping reinforcement technology, polished and polished multiple times, round and smooth without burrs, which not only avoids scratching hands during use, but also enhances the toughness of the can mouth, preventing deformation and damage caused by long-term opening and closing; the can bottom adopts anti-slip and wear-resistant base, made of high-hardness rubber material, not easy to wear or age, not easy to slide when placed, and can buffer the impact force when dropped, further improving the overall durability; the overall structure has passed strict fatigue test, and remains stable after frequent opening and closing and repeated cleaning, suitable for long-term high-frequency use needs, balancing durability and practicality, so that every meal can be protected for a long time.
