The outer body and lid are food-grade polypropylene (PP) — lightweight, impact-resistant, and BPA-free; the ‘stainless steel’ designation refers specifically to the inner food tray, which is 304 (06Cr19Ni10) austenitic stainless steel — the premium food-contact grade used in professional cookware and kitchenware; this combination gives the lunch box the lightness and design flexibility of plastic on the outside with the hygiene and durability of stainless steel where food actually contacts the surface
The silicone sealing ring in each compartment lid creates an independent seal per section — liquid or sauce from one compartment cannot transfer to another, making it practical for packing meals that include both dry and wet components in the same box
Features
3 independently sealed compartments for complete meal separation — each of the 3 compartments has its own silicone sealing ring, meaning sauce or liquid from a curry, yoghurt, or fruit section cannot leak into a dry section like rice or bread; the child can have a complete lunch — a main, a side, and a snack — in one leak-resistant box without any flavour or moisture transfer between sections
304 stainless steel inner tray for safe, hygienic food contact — the food-contact surface is 06Cr19Ni10 stainless steel (equivalent to 304 grade), which does not leach chemicals, does not absorb food odours or flavours, and is non-reactive with acidic foods such as tomatoes, citrus, and yoghurt; this is the same material standard used in professional kitchen equipment and premium cookware
600 ML total capacity suitable for a full school or office meal — at 600 ML divided across 3 compartments, the box holds a practical lunch volume for a school-age child or a light adult meal; the 3-section format encourages a balanced meal by physically separating the main from sides and snacks
Temperature range of -20°C to 100°C for hot and cold foods — the box can hold refrigerator-cold foods directly and is rated to accept warm foods up to 100°C, making it usable for freshly cooked meals packed for school, office, or travel without waiting for food to cool down first
Blue Astronaut space theme — the design on the lid features floating astronauts in full space suits, colourful planets including a ringed Saturn-type planet, a blue Earth, and various smaller planets in pink, orange, and yellow, alongside rockets and stars on a sky-blue background with a lime green frame; the ‘Space’ text on the lime green centre divider makes the theme explicit and immediately recognisable to children; the design is calibrated to appeal to school-age children (approximately ages 4–9) who are engaged with space, science, and exploration themes
Clip-lock closure for secure carrying — the lime green PP clip locks the lid securely, preventing accidental opening in a school bag and providing reassurance that the seals are engaged before the child or parent carries it
Use Cases
School lunch box for children: packing a complete balanced school lunch — rice or roti in the main compartment, a sabzi or curry in the sealed wet compartment, and a fruit or biscuit snack in the third section; all three sections stay separate and leak-free in the school bag
Office tiffin for light meals: a 600 ML 3-section box works for adults who pack a moderate office lunch and want to keep different components separated; the stainless steel tray is hygienic and easy to clean in an office setting
Gifting for school-going children: a practical and child-appealing gift for a school-age child starting a new term, a birthday present, or an Eid gift; the space theme makes it feel like a fun, personal gift rather than a generic functional item
Meal prep and portioning: using the 3 sealed compartments to pre-portion a child’s snacks and meals for the day — stored in the fridge overnight and ready to pack in the morning without any assembly
Hand wash recommended for the PP outer body and lid — the polypropylene body retains its shape, colour, and print best with hand washing in warm soapy water; avoid very high heat dishwasher cycles for the plastic components
The stainless steel inner tray can be washed separately — remove the tray from the PP body for thorough cleaning; the 304 stainless steel surface is easy to clean with warm soapy water and a soft sponge; it is dishwasher safe as a metal component
Clean the silicone sealing rings regularly — remove the silicone rings from each compartment lid periodically and wash separately with warm soapy water; food residue can accumulate around the ring groove and affect the seal if not cleaned
Do not use abrasive sponges on the decorated lid surface — the astronaut and space print on the blue PP lid can be scratched by abrasive pads; use a soft sponge or cloth
Temperature safe from -20°C to 100°C — the lunch box can be used with both cold foods (refrigerated or chilled) and warm foods up to 100°C; do not place in a conventional oven or on a direct heat source
Do not microwave the full assembled box — the stainless steel tray is not microwave safe; if reheating is needed, remove food to a microwave-safe dish first
Dry all components thoroughly before reassembling — ensuring the tray, lid, and silicone rings are fully dry before closing prevents trapped moisture and odour

Frequently Asked Questions
This is a hybrid construction lunch box. The outer body, lid, frame, and clips are food-grade polypropylene (PP) plastic — a lightweight, impact-resistant, BPA-free material. The inner food tray (the surface that your food actually sits on) is 304-grade austenitic stainless steel (06Cr19Ni10) — the same premium food-contact steel grade used in professional kitchen equipment and cookware. This is the most practical combination for a children’s lunch box: the PP outer shell keeps it lightweight and gives room for the fun astronaut design, while the stainless steel tray provides a hygienic, non-reactive, odour-free food contact surface that does not leach chemicals. The sealing rings on each compartment are silicone, which is food safe, flexible, and heat-resistant. So when the product is described as a ‘stainless steel lunch box’, that refers specifically to the inner tray — the part that matters for food contact hygiene.
Yes — each of the 3 compartments has its own individual silicone sealing ring, meaning each section seals independently. Sauce, liquid, or moisture from one compartment cannot transfer to another. This is the key practical advantage of this design over basic compartmented lunch boxes that use a single lid seal for the entire tray. In practical terms, you can pack a wet curry or yoghurt in one section and dry rice or bread in another, and the dry section will remain completely dry. For a school lunch, this means a full meal — a main, a wet side, and a dry snack — can travel in one box without any cross-contamination or flavour transfer, even if the box is turned on its side in a school bag.
Do not microwave the assembled lunch box — the stainless steel inner tray is not microwave safe. If you need to reheat food, transfer it to a microwave-safe dish or plate first. For dishwasher use: the stainless steel tray can be washed in the dishwasher as a metal component, but hand washing is recommended for the PP plastic outer body and lid to preserve the printed astronaut design and the clip mechanism over time; the silicone sealing rings should be removed and hand washed separately. The temperature rating of -20°C to 100°C means the box is suitable for use with hot foods packed directly from cooking, refrigerator-cold foods, and frozen storage, but it is not designed for oven or microwave heating in its assembled form.
The Laxson Blue Astronaut Lunch Box is best suited to school-age children, approximately 4 to 10 years old. The space and astronaut design is calibrated to appeal to this age group — children who are curious about space, planets, and exploration, and for whom a themed lunch box makes the school day a little more exciting. At 600 ML total capacity across 3 compartments, the volume is appropriate for a child’s school lunch rather than a large adult meal. The clip-lock mechanism is straightforward enough for most school-age children to open and close independently, which matters for lunchtime independence. The bright blue and lime green colour combination and the illustrated astronaut characters are deliberately playful and child-oriented. It would also work as a practical tiffin for a teenager or adult who packs moderate portions, though the design is primarily aimed at the younger school-age segment.
Yes — this lunch box is manufactured to Chinese national food safety standards GB4806.7 (plastics in food contact) and GB4806.9 (metal materials in food contact). These are China’s mandatory national standards for food contact materials, covering migration limits and chemical safety requirements for plastics, metals, and rubber materials that come into contact with food. The manufacturer, Shantou Linxiang Plastics Co. Ltd, holds production licence 粤XK16-204-11899. The PP body is a propylene homopolymer — a food-safe, BPA-free plastic. The inner tray is 304-grade stainless steel, which is non-reactive, does not leach chemicals, and is universally recognised as the premium food-contact metal standard. The silicone sealing rings are food-grade silicone. For a lunch box intended for children, the combination of these materials and the GB4806 certification provides a solid, verifiable food safety baseline.
