Professional Gastronorm Containers – Complete Guide, MOCA Regulations and Compatibility

Professional Gastronorm Containers – Complete Technical Guide for Ho.Re.Ca. and Food Processing Environments

Gastronorm containers (GN) represent the international standard for modular food containers used in professional kitchens, food laboratories, catering services, hotels, canteens, refrigerated counters, display buffets, and industrial food environments. Their standard dimensions—defined for perfect compatibility with ovens, refrigerated units, blast chillers, bain-marie systems, trolleys, dishwashers, and storage elements—have made the Gastronorm system essential for efficiency, hygiene, and operational organisation.

What Is the Gastronorm System?

The Gastronorm system was introduced in Switzerland during the 1960s to standardise the sizing of containers, trays, and equipment used for professional food preparation. Today, the GN system is recognised as an international reference point and is widely implemented in the Ho.Re.Ca. sector.

The fundamental unit of measurement is GN 1/1 (530 × 325 mm), from which all other formats—multiples and submultiples—are derived. Thanks to this modular approach, containers from different manufacturers can be combined without needing structural modifications.

Why Gastronorm Containers Are Essential in Professional Kitchens

• Universal compatibility: ovens, blast chillers, fridges, counters, bain-maries and trolleys are designed around GN standards.
• Optimised workflows: operations become faster, cleaner and more organised.
• Food safety: certified food-contact materials ensure compliance with hygiene requirements.
• Space efficiency: modularity allows maximum use of every shelf, trolley and preparation area.
• High durability: stainless steel AISI 304 and BPA-free polycarbonate ensure long-lasting reliability.

Gastronorm Materials: Stainless Steel and Polycarbonate

ItaliaGroup offers a complete range of Gastronorm containers made from:

✔ Stainless Steel AISI 304

Stainless steel 18/10 AISI 304 is the benchmark for professional kitchens due to its resistance to corrosion, shocks, temperature changes and intensive washing cycles. Its chrome and nickel composition ensures superior durability, hygienic performance and structural stability under heavy use.

✔ Polycarbonate (BPA-Free)

Polycarbonate GN containers guarantee transparency, lightness and resistance to temperatures from –40°C to +100°C, making them suitable for refrigerated storage, preparation counters and cold buffets. All ItaliaGroup polycarbonate GN containers are MOCA-certified and free of bisphenol A (BPA).

MOCA Certification: A Fundamental Requirement

All ItaliaGroup containers are compliant with the European MOCA regulation (Materials and Objects in Contact with Food), ensuring:

• complete traceability of raw materials;
• laboratory tests confirming suitability for food contact;
• absence of harmful substances migration;
• safe usage in professional environments.

MOCA-certified containers are essential for restaurants, laboratories, food industries and all businesses subject to HACCP requirements.
