Buyers ask this before almost anything else, because it decides whether bagasse can replace the
plastic containers they are using now. The short answer: Heat resistant to about 100–120 °C, short-term oven tolerance up to 200 °C, freezer-safe to about −20 to −25 °C.
What the temperature figures mean in practice
- Microwave reheating (up to about 100–120 °C) — the normal case for takeaway,
canteen and delivery food. - Short-term oven exposure (up to about 200 °C) — useful for holding hot food,
not for long baking. Keep it short and do not use it under a grill. - Freezer storage (about −20 to −25 °C) — you can freeze in it and reheat after.
These are the figures for our own tableware. If your programme has a specific temperature step that
worries you — a hot-hold cabinet, a combi oven, a long freeze-then-blast-reheat cycle — say so when you
enquire and we will tell you honestly whether we can support it.
Where bagasse beats the alternatives
Heat tolerance is the practical reason moulded fibre is chosen over PLA. PLA — the material used in
many biodegradable food containers — starts to soften at far lower temperatures, which rules it
out for hot meals. Moulded bagasse fibre holds its shape across the microwave-and-freezer range that
foodservice actually uses.
It is also a different proposition from coated paperboard: there is no polyethylene lining, so there
is no plastic layer to separate from the food residue, and no PFAS is needed to get grease resistance.
How to get the best out of it
- Use it for reheating rather than long high-power cooking.
- Let frozen items stand briefly before microwaving — a big temperature step is hard on any fibre product.
- Do not use it under a grill or over an open flame.
- Store it dry before use; that applies to any moulded fibre tableware.
What this article does not claim
It does not claim the tableware is indestructible, and it does not come with a shelf-life
guarantee — we do not quote a shelf life, because we do not have tested data for one. If a storage
specification matters to your project, ask us and we will tell you what we can and cannot confirm.
Where it fits in your range
Heat tolerance matters most for bowls & cups,
trays and
clamshells — the formats that carry hot meals. Plates and
the lids and cutlery that go with them are covered by the
same material. See the full catalogue on our collections page.

Frequently asked questions
Can bagasse tableware go in the microwave?
Yes. It is heat resistant to about 100u2013120 u00b0C, which covers normal reheating. Use normal microwave times rather than extended high-power cycles.
Can it go in a conventional oven?
Short-term oven exposure up to about 200 u00b0C is tolerated. It is a moulded fibre product, so keep oven use short and do not put it under a grill.
Is it freezer safe?
Yes u2014 freezer-safe to about u221220 to u221225 u00b0C, so it can go straight from the freezer.
Can I move it straight from the freezer to the microwave?
The material handles both ranges, but a large temperature step is hard on any moulded fibre product. Letting it stand briefly reduces the risk of warping.
What is the minimum order?
100 cartons per model.
