Materials Used To Manufacture A Gastronorm Container Bag

A Gastronorm (GN) container bag is an essential tool in professional kitchens, catering services, and food transport operations. Designed for durability, functionality, and temperature control, these bags must safely carry standardized gastronorm containers while protecting food quality. To meet these demands, manufacturers use a combination of high-performance materials for different parts of the bag—each serving a specific purpose in strength, insulation, water resistance, and usability.

Core Materials and Their Functions

Cordura Nylon

Cordura nylon is a premium synthetic fabric renowned for its exceptional strength-to-weight ratio and resistance to abrasions, tears, and scuffing. In gastronorm container bags, it forms the primary outer shell, providing structural integrity and long-term durability even under heavy daily use.

Its rugged construction makes it ideal for catering companies, chefs, and delivery services that frequently transport equipment across various environments. Despite its toughness, Cordura remains lightweight, ensuring the bag doesn’t add unnecessary bulk or weight when empty—making it easier to carry over extended periods.

PVC Coating

To enhance protection, the Cordura or other fabric layers are often treated with a Polyvinyl Chloride (PVC) coating. This layer provides full waterproofing, preventing moisture from penetrating the bag during spills, rain, or cleaning.

The seamless application of PVC ensures no water seeps through stitching or fabric pores, keeping both the container and its contents dry. Additionally, the coating increases the material’s stiffness and wear resistance, contributing to the bag’s overall lifespan and ease of cleaning—simply wipe down with a damp cloth for maintenance.

Foil Insulation

For temperature-sensitive transport, many GN bags incorporate foil insulation between inner and outer fabric layers. This reflective thermal barrier works by minimizing heat transfer—keeping hot foods hot and cold items cold during transit.

The aluminum-based foil reflects radiant heat, while the insulating core (often foam or fiber-based) reduces conductive heat loss. This combination is especially valuable for caterers, meal prep services, and mobile kitchens where maintaining food safety temperatures is critical. Depending on thickness and design, some insulated GN bags can maintain internal temperatures for several hours.

YKK Zippers

High-quality YKK zippers—produced by the Japanese company Yoshida Kogyo Kabushikigaisha—are the industry standard in premium gastronorm bags. Known for their precision engineering, smooth operation, and long-term reliability, YKK zippers ensure secure closure and prevent accidental spills.

These zippers resist corrosion, withstand repeated use, and maintain alignment even under load, which is crucial when carrying heavy containers. Their dependable performance enhances safety and convenience, especially in fast-paced environments where quick access and secure storage are equally important.

Padded Dividers

Inside many multi-compartment GN bags, you'll find padded dividers made from closed-cell foam or soft fabric padding. These dividers separate individual gastronorm containers, preventing them from knocking into each other during transport.

This not only protects the containers from dents and scratches but also stabilizes the load, reducing shifting that could lead to imbalance or dropped bags. The padding also adds an extra layer of insulation and shock absorption, improving both food safety and equipment longevity—especially important when transporting delicate dishes or moving between locations quickly.

Reinforced Handles & Stitching

While not always listed separately, reinforced webbing handles and double or triple stitching are critical structural components. Made from polyester or nylon webbing, these handles are designed to support heavy loads without tearing or straining.

Strategic reinforcement at stress points (like corners and attachment zones) prevents premature wear. Combined with bar-tacking at high-tension areas, this ensures the bag remains functional even after years of rigorous use in commercial settings.
