Kids’ lunch boxes, stainless and plastic, rated on materials

• 18/8 is stated; 304 is not, though the two are equivalent designations. A small gap in an otherwise complete disclosure. [1]
• No seal, and they say so: “This product is not leak proof. We recommend packing dry foods only.” Honest, and it means no silicone question arises at all. [1]
• An optional snap-on plastic cover is sold separately with no resin named. It is not part of this product. [1]
• Country of manufacture and warranty terms are not published on the product page. [1]

• The claims are “independently tested to meet FDA food safety standards” for the steel and “independently tested and LFGB certified” for the silicone. Standards are named; the laboratory is not, and no report is published. That is why testing scores 2 and not 3. [1]
• There is no warranty at all. Their returns policy says: “As a small business, we cannot accept returns or exchanges for change of mind”, and no defect warranty is offered anywhere on the site. [1]
• “Pure food grade silicone” is the phrase we dock everyone for, and we are not making an exception here. Food grade is not a certification — no agency issues it. The LFGB claim is the substantive one; “food grade” adds nothing. [1]
• “BPA Free” on stainless steel and silicone rules out a molecule that was never plausible in either material. True, and costless. [1]
• Do not confuse this brand with Nude Food Movers, which is a different company and discloses considerably less.
• $95 is the top of this market. You are paying for the disclosure and the five compartments.

• Ever Eco’s own FAQ says its bento boxes have no seal, because “they would require a plastic/silicone seal in the lid, however we chose to keep them 100% stainless steel”. This product page sells a silicone lid seal. Both are Ever Eco’s. [1] [2]
• Its own 1400ml bento cites a different standard for the same component — “FDA grade silicone” rather than LFGB. Same brand, same part, two standards, neither with a certificate. [3]
• “Plastic free” sits awkwardly next to a silicone seal and an unnamed lid. [1]
• Cure type not stated. Country given only at brand level in the FAQ — “China, India and Indonesia” — not per product. [1] [2]

• We chased the LFGB page. It defines LFGB generically — “a premium grade of silicone that has passed LFGB testing standards” — and names no lab, no certificate number, no standard number and no product list. Treat it as marketing copy, not evidence. [2]
• “100% plastic-free” is hard to square with the silicone-lidded pots sold as part of the same system. [1]
• “No microplastics” is an unfalsifiable claim with no test behind it. [1]
• Seed & Sprout’s wider range does make the broadest chemical exclusion we found anywhere — BPA, phthalates, cadmium, mercury, PVC, dioxin, GenX, PFAS, and the D4 and D5 siloxanes. It is the only brand in this table that names siloxanes at all. [3]

• Silicone seals are named as silicone and nothing more — no cure type, no LFGB, no EC 1935/2004. [1]
• The product page says “Dishwasher Safety Tested for Top Rack”; the FAQ says stainless items are “hand washed only”. Two Yumbox pages, two answers. [1] [2]
• “CPSIA and FDA compliant” is self-declared. No certificate, no lab. [2]
• Yumbox does not state a country. Biome states “Made in China” — a retailer claim we could not verify against the maker. [1] [3]

• The lid material is still not published, and it is the part that sits over the food. [1]
• No certification, no country of manufacture, no warranty on the product page. [1]
• Compare its sealed siblings, where “plastic free” runs alongside a silicone seal and Ever Eco’s own FAQ claims there is no seal at all. [2]

• The included knife and fork have no material stated. They are food-contact items in a product whose entire selling point is glass. [1]
• No seal or gasket material is listed, despite an “air and water tight” claim. [1]
• Borosilicate is chosen for thermal-shock resistance, and the care note then imposes a limit: “do not place it in a pre heated oven above 120 deg. C”. No oven rating is given anywhere else on the page. [1]
• Target lists the same product with dimensions of “21.2cm (H) x 16cm (W) x 7.5cm (D)”. A 21cm-tall lunchbox is implausible; height and depth appear transposed. [2]

• We score the grade as unspecified, because two Australian retailers publish different specifications for one SKU and the manufacturer publishes none. [1] [2]
• Marketed as leakproof and airtight, with no gasket material named by either retailer. [1] [2]
• Officeworks says “Microwave Safe: No”. Big W says top-rack dishwasher safe with hand washing recommended. Twelve-month warranty per Big W. [1] [2]
• No country of manufacture and no certification from any source. [1] [2]

• BPA is a plastic monomer. If the product were genuinely 100% plastic-free, certifying it BPA-free would be meaningless — you do not BPA-test a stainless and ceramic object. One of those two statements is doing dishonest work, and a leak-resistant modular box almost certainly has elastomer seals. [1]
• “FDA & EU approved safe” is not a certification. The FDA does not approve lunchboxes; it sets food-contact material requirements. No standard number, no notified body, no lab, no certificate. [1]
• “Leak resistant” is the only description of the seals. Their material is not given. [1]
• Country of manufacture not stated. Hand wash only. [1]

• “BPA free” on polypropylene. PP never contained BPA — BPA is a polycarbonate and epoxy monomer — so the claim is true and uninformative, and it says nothing about BPS or BPF. [1]
• The silicone has no grade, no cure type and no standard. “Silicone” is the whole of it. [1]
• “Microwave, dishwasher and freezer safe” appears unqualified, then the care text requires opening the lid before reheating. The lid is not fully microwave rated and the bullet does not say so. [1]
• Compare Big W’s K-D Hard Square Bento at $8, which names no material at all and claims “No added BPA”. [2]

• The body is “Silicone and polypropylene (PP)” without saying which part is which — presumably the collapsible walls are silicone and the rigid frame is PP, but the page does not say. [1]
• No grade, cure type or standard for the silicone, and no grade for the PP. [1]
• “BPA free”, which on PP and silicone is true by construction. [1]
• No warranty, no country of manufacture, no third-party testing — consistent with every Kmart product we checked. [1]

• “Partly plant-based” is the environmental headline and the undisclosed remainder is conventional PP. A 5% filler and a 50% filler would both be described this way. [1]
• Three food-contact components — two removable trays and a snack pot — and the lid and pot materials are not separately stated. [1]
• “BPA free” on polypropylene, which never contained it. [1]
• No warranty, no country of manufacture, no third-party testing. [1]

• The claim is “BPA-, phthalate-, and PVC-free”. Three exclusions, and nothing about PFAS — which is notable, because b.box’s US listings do claim PFAS-free while its Australian pages do not. [1]
• Which part is the PP and which is the silicone is not published. Lid, clips and the included ice pack contents are all unstated. [1]
• No third-party testing. The claims rest on material type rather than on any test report or certification. [1]
• Country of manufacture not published. No warranty. Myer’s listing carries no material, BPA, PVC or phthalate statement at all on a children’s product. [2]

• Tritan is marketed as BPA-free by design, so the “BPA & Phthalate-free” claim is consistent — but it says nothing about the other bisphenol analogues used as substitutes. [1]
• “Silicone seal system” — named, with no cure type and no standard body. [1]
• No certification mentioned, no country of manufacture, no warranty on the product page. [1]
• “Dishwasher safe (top shelf)*” — the asterisk points to conditions that are not shown on the page. [1]

• The combined materials line is “18/8 304 grade stainless steel, food grade plastic & silicone” — three materials, one of them a real specification and one of them a placeholder. [1]
• The silicone gasket is removable and named as silicone. Cure type not stated, no standard body cited. [1]
• “FDA, CPSIA, CPSA compliant” is self-declared with no certificate or lab published. [1]
• Leakproof only “for up to 1 teaspoon liquid”, which is an unusually honest limit. One year limited warranty. Country not published. [1]

• Marketed as leakproof, and the same page says “Do not pack water or watery food. Yumbox does not hold water.” [1]
• The seal is described elsewhere as a “precision silicone seal” — named, no grade, no standard. [1]
• “FDA and CPSIA compliant” is self-declared. No certificate, no lab. [1]
• One year warranty. Country of manufacture not published. [1]

• “PP and silicone” is a material family, not a specification. No food-contact standard is named for the polypropylene and no grade for the silicone. [1]
• No country of manufacture stated anywhere we could find. b.box describes itself as “an award-winning, Australian-owned company” — ownership is not manufacture. [1]
• No third-party testing, no certification, no laboratory named. [1]
• The six-month guarantee excludes “rips, spills, scratches, chips, mould, fading, stains and odour” — which covers essentially every way a child’s lunchbox fails. [1]
• Cheap, widely stocked and genuinely popular. The score is about disclosure, not whether your kid will like it.

• “Made in New Zealand” — and this is the ONLY product in the entire lunchbox category, from any brand, that states a country of manufacture on the maker’s own product page. [1]
• The range page carries a “BPA-free” claim. The individual product page carries no BPA claim at all. Category-level claim, product-level silence. [1] [2]
• Gasket material not published, on a product with a “seal-tight screw-top lid”. [1]
• The care guidance is the best-documented in this category: top-rack dishwasher, microwave without the lid, freezer safe, and an explicit list of what not to do — no conventional oven, hot plate, grill, stovetop or convection microwave. [1]

• We score the maker, so the resin is unstated. But the retailer’s breakdown is worth knowing, and it should not have to come from a shop. [1] [2]
• Bentgo is the only brand in this category making a PFAS-free claim, and it names no test method, lab or standard behind it. BPS and BPF are not excluded. [1]
• The same retailer adds “FDA-approved, food-safe materials”. The FDA does not approve food-contact materials, so that line is simply wrong. [2]
• Best care disclosure of the plastic group: tray freezer safe, microwave safe, top-shelf dishwasher; hand wash the outer shell. Warranty one to two years. Country not published. [1]

• No grade, no cure type, no “food grade” qualifier, no LFGB or FDA reference. Just the word silicone. [1]
• “BPA free” on a silicone product. BPA is a polycarbonate and epoxy monomer; silicone never contained it. The claim is attached to the material where it cannot apply, and withheld from the lid where it might. [1]
• “Do not reheat food for more than 2 minutes at a time” on the Target listing, with no reason given. [2]
• Big W’s K-D Silicone Bento at $8 is the same story: silicone in the product name, no grade, and a “Removable Lid” whose material is not published. Its care text is also truncated mid-sentence on the live page. [3]

• No BPA claim at all, while its sibling K-D hard bento claims “No added BPA”. Two children’s products, one range, two different standards of claim. [2]
• The care text contradicts itself: “Dishwasher and microwave safe” in one breath and “For reheating only and not suitable for cooking” in the next, with no temperature ceiling given. [1]
• That care sentence is truncated mid-clause on the live page: “Do not use sharp utensils to cut directly in this”. [1]
• No certification, no country of manufacture, no warranty. [1]

• Water- and stain-resistant bag linings are a known PFAS application. This is the one product category in this table where a PFAS question is genuinely open, and the page is silent on it. [1]
• The lining is a de facto food-contact surface whenever food is unwrapped in the bag, and its material is not published. [1]
• Insulation, zip and hardware: all unstated. [1]
• “Easy to clean” is the entire care instruction. No warranty, no country of manufacture. [1]

• For a wipe-clean insulated lining, PFAS is the open question, and it is the one the page does not address either way. With the lining material unnamed there is no way to reason about it at all. [1]
• The cooling panel is the only component described: “290ml of liquid”, “non-toxic purified salt water”. Credit where it is due — most gel packs say nothing. [1]
• This is a bag rather than a food-contact tray, so it scores differently from the rest of this category. The lining still meets unwrapped food. [1]
• No certification, no country of manufacture, no warranty. [1]

• No polymer type for the body. No material for the lid or seal. For a food container aimed at children, this is the thinnest disclosure on the Australian list. [1]
• “BPA free” on an unnamed plastic tells you one molecule is absent from a material you have not been told the identity of. See why that claim is narrower than it sounds. [1]
• No warranty found on the product page. [1]
• None of this means the product is unsafe. It means nothing about it can be checked from outside the company — and under Australian law they are not required to tell you. That is the finding.
