Reusable bottles, flasks and food containers

This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
The material page does the work: 18/8 against 18/10 against 316 stainless, copolyester, glass and lined aluminium, and what the EU food-contact rules plus the 2024 bisphenol A ban now mean for a "BPA-free" sticker.
The second anchor is a repeatable insulation test — measured water temperature at 6 and 12 hours, written so a reader can run it on the flask already in the cupboard. ~14 item pages including lids and biofilm, a cleaning schedule with the published swab findings, dishwasher damage to a vacuum wall, acidic drinks, kids' straw parts, collapsible and filter bottles, published microplastic release, and what cracks when frozen.
How to use it
Use Reusable bottles, flasks and food containers to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: Regulation (EU) No 10/2011 and Regulation (EU) 2024/3190 on bisphenol A (EUR-Lex, reusable), published bottle-hygiene swab studies and microplastic release studies (cited); insulation test method own writing. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
