What Are Polycarbonate Gastronorm Pans?

Understanding Polycarbonate Material

Polycarbonate is a thermoplastic polymer renowned for its exceptional strength-to-weight ratio and optical clarity. In foodservice applications, polycarbonate gastronorm containers leverage these material properties to create food storage solutions that are:

Virtually Unbreakable: Polycarbonate material exhibits remarkable impact resistance, able to withstand drops from counter height without cracking or shattering. This durability dramatically reduces replacement costs compared to glass or acrylic alternatives.

Crystal Clear: The transparency of polycarbonate gastronorm pans rivals glass, allowing kitchen staff to instantly identify contents, assess food quality, and determine inventory levels at a glance. This visibility reduces unnecessary container opening, helping maintain food temperatures and minimize contamination risks.

Temperature Versatile: Quality polycarbonate gastronorm containers safely operate across a wide temperature range from -40°C (-40°F) to +99°C (210°F). This versatility means the same polycarbonate gastronorm pan can move from freezer storage to refrigeration to hot holding applications.

Lightweight: Despite their strength, polycarbonate gastronorms weigh significantly less than stainless steel equivalents, reducing physical strain on staff during repeated handling and transport.

Chemical Resistant: Polycarbonate resists acids, fats, and most food-related chemicals, preventing staining and odor absorption that plagues some other plastic materials.

The Gastronorm Standard Explained

The gastronorm (GN) standard, formally known as EN 631-1:1993 in Europe and similar standards globally, establishes unified dimensions for food storage containers and compatible equipment. This standardization originated in Switzerland during the 1960s to address compatibility issues between kitchen equipment from different manufacturers.

Standard Base Size: The gastronorm system uses GN 1/1 (full size) as its base measurement: 530mm × 325mm (20.87″ × 12.80″). All other gastronorm sizes represent precise fractions or multiples of this dimension.

Universal Compatibility: Equipment designed to gastronorm specifications—including refrigerators, blast chillers, bain maries, prep tables, and transport carts—accepts any gastronorm-sized container regardless of manufacturer. This interoperability simplifies equipment procurement and operational flexibility.

Fraction System: The naming convention (1/2, 1/3, 1/6, etc.) indicates how many containers of that size fit into a full GN 1/1 footprint. For example, two polycarbonate gastronorm 1/2 pans equal one GN 1/1 space.

Why Choose Polycarbonate Over Other Materials?

Versus Stainless Steel:

Polycarbonate gastronorm containers cost 40-60% less than equivalent stainless steel
Transparency allows content identification without opening
Lighter weight reduces handling fatigue
No metal transfer reactions with acidic foods
However, stainless steel offers higher temperature tolerance for cooking applications

Versus Standard Plastic (Polypropylene):

Superior clarity—polypropylene tends to be translucent or opaque
Greater impact resistance and durability
Better low-temperature performance without becoming brittle
Maintains clarity longer without clouding
Polypropylene offers slightly higher heat resistance (up to 120°C)

Versus Glass:

Dramatically more impact-resistant—won’t shatter if dropped
Significantly lighter weight for easier handling
Lower cost per unit
Glass offers better scratch resistance and doesn’t cloud over time

For food service operations prioritizing durability, visibility, and value, polycarbonate gastronorm pans deliver an optimal combination of properties that neither metal nor alternative plastic materials can match.
