Choose polycarbonate when you want to see what is inside and need tough, stackable storage in the cold. Choose polypropylene for light, budget friendly containers. Choose stainless steel when food goes near heat, a Bain Marie or an oven. Most busy kitchens end up using a mix.
Every kitchen ends up debating this at some point. Which container goes in the fridge, which one goes on the hot pass, and which one is cheap enough to hand over with a takeaway? The honest answer depends on temperature, handling and how much you want to see at a glance.
Is polycarbonate a good choice for food storage?
Polycarbonate is clear, tough and stackable, so it is a favourite for fridges, prep stations and cold displays. You can read the contents without opening a lid, which speeds up stock checks. The limits matter, though. The 1/1 clear polycarbonate GN pan we stock is rated from minus 40 to 100°C, and its product page says not to use it in a Bain Marie. Think cold storage, prep and presentation rather than hot holding.
When does polypropylene make more sense?
Polypropylene is light and usually the most affordable of the three. It copes well with many cleaning products, though it is typically cloudy rather than glass clear and can pick up colour from sauces based on tomato. It suits dry storage, sauce prep and takeaway portions, where weight and price matter more than a clear view. Temperature limits vary between products, so read the rating on each item before it goes near heat.
Why do so many kitchens still rely on stainless steel?
Stainless steel takes direct heat, Bain Marie service, ovens and hard washing without staining or holding on to odours. It costs more upfront and weighs more, and you cannot see inside it, so labelling becomes part of the routine. For stockpots, saucepans and anything that meets a flame, our stainless steel cookware range is the natural place to look.
Which Material Should You Choose for Each Job?
- Fridge shelves and cold prep: polycarbonate, for visibility and easy stacking.
- Dry goods, sauces and takeaway portions: polypropylene, for low weight and cost.
- Hot holding, Bain Marie and oven work: stainless steel, for heat tolerance.
- Buffets and displays: clear polycarbonate for cold food, stainless steel for hot.
How do you build a mixed set without waste?
Most kitchens do best with stainless steel for hot service and polycarbonate for cold prep, adding polypropylene where cost or weight is the concern. Gastronorm sizing is standardised, so pans in different materials usually share racking, though it is worth checking lids before you order. For a wider look at what a busy kitchen needs, our post on essential catering supplies for busy restaurants is a useful companion.
What should you check before ordering?
- The temperature range on the product page
- Whether the item is rated for Bain Marie use
- Capacity and depth (our 150mm deep 1/1 polycarbonate pan hold 19.5L at 530 x 325mm)
- Lid availability and washing instructions

Frequently Asked Questions About Polycarbonate, Polypropylene and Stainless Steel
Polycarbonate is better when you want to see the contents and need tough, stackable cold storage. Polypropylene is better when you want something light and affordable for dry goods or takeaway use.
Not the ones we list. Our polycarbonate GN pans are marked not for Bain Marie use and rated to 100°C, so use stainless steel for hot holding.
For heat, yes. Stainless steel tolerates direct heat, ovens and Bain Marie service, while plastics come with temperature limits that should not be exceeded.
Stainless steel resists staining and odours best. Polycarbonate wipes clean but can scratch under abrasive pads, and polypropylene may take on colour from strong sauces. Follow each manufacturer's care instructions.
A gastronorm (GN) pan is a standard sized catering container that fits racks, counters and Bain Maries. A 1/1 pan is the full size, measuring 530 x 325mm.
Stainless steel generally handles heat and rough handling best. Lifespan still depends on how an item is used, washed and stored, so no material lasts forever.
