What Is Food-Grade Plastic and Which Materials Are Used in Professional Environments?

Food-grade plastic refers to plastic that manufacturers have produced and assessed for use in direct or indirect contact with food without endangering human health or altering the product’s characteristics. The food industry, commercial kitchens, cold rooms, warehouses, supermarkets, laboratories and catering companies commonly use these materials.

However, not every plastic is suitable for this purpose. A material’s suitability depends not only on whether it consists of PVC, polyethylene or polypropylene, but also on its formulation, manufacturing process and specific conditions of use.

Temperature, contact time, food type and cleaning products can all influence the choice of material. It is therefore important to distinguish between general-purpose plastic and material specifically formulated and certified for food environments.

What requirements must food-grade plastic meet?

Materials intended to come into contact with food must remain sufficiently inert to prevent substances from transferring into quantities that could endanger human health. They must not cause unacceptable changes to the composition, smell, taste or appearance of food, in accordance with Regulation (EC) No 1935/2004.

For plastic materials specifically, Regulation (EU) No 10/2011 sets requirements for authorised substances, migration limits and conditions of use. Manufacturers must also follow the good manufacturing practices established in Regulation (EC) No 2023/2006.

Essential properties for professional environments

In addition to meeting regulatory requirements, materials suitable for food use must withstand the demands of each professional environment. The most important characteristics include:

• Smooth, easy-to-clean surfaces.
• Low moisture absorption.
• Resistance to corrosion.
• Ability to withstand frequent cleaning.
• Stability at the expected operating temperatures.
• Resistance to impacts, loads and continuous use.
• No cracks or areas where dirt can accumulate.

Equipment design also plays a key role. Even when the material itself is suitable, joints that are difficult to clean or inaccessible corners can make it harder to maintain proper hygiene.

Most used materials

The food industry uses different types of plastic because no single material suits every application. Each option offers specific properties, so businesses must select it according to the type of food, expected contact and working conditions.

Food-grade PVC

Food-grade PVC uses a formulation designed to meet the requirements that apply to food contact under specific conditions of use. Its resistance to moisture, durability and ease of maintenance make PVC shelving and other thermoplastic equipment particularly well suited to professional environments with strict hygiene requirements.

However, not every PVC product is suitable for direct food contact. Businesses must check that its composition, documentation and intended use match the type of food, temperature and contact conditions. The same applies to so-called sanitary-grade PVC: although manufacturers design it for environments that require high hygiene standards, the relevant documentation must confirm its suitability for food contact.

Polyethylene and polypropylene

Polyethylene and polypropylene are widely used in the food industry. Polyethylene, particularly in its high- and low-density forms, offers moisture resistance and low weight, making it suitable for packaging, tanks, chopping boards, bags and machine components. Polypropylene also provides good chemical resistance and, in certain formulations, withstands higher temperatures. Manufacturers therefore use it for reusable containers, trays, boxes, lids, utensils and packaging exposed to thermal processes.

As with PVC, products made from polyethylene or polypropylene do not automatically qualify as food-grade. The manufacturer’s technical documentation must support both the formulation and the intended conditions of use.

Applications in the food industry

Food-grade plastics play a role throughout food production, handling, storage and distribution. Common applications include:

• Food packaging, boxes and containers.
• Trays and food-handling surfaces.
• Tanks and piping systems.
• Components for machinery and production lines.
• Curtains and partitions for cold rooms.
• Shelving, lockers and furniture for work areas.
• Trolleys for transporting utensils, products or raw materials.
• Cladding and components for areas exposed to moisture.

Storage in cold rooms and warehouses

In warehouses, food preparation areas and cold rooms, moisture-resistant, easy-to-clean equipment helps maintain order and simplify hygiene routines.

For example, cold room shelving can withstand low temperatures and constant humidity. Its design helps businesses organise products and containers while making better use of the available space.

Equipment for hospitality and catering

Commercial kitchens, hotels, restaurants and catering companies need furniture that can withstand intensive use and frequent cleaning. In these environments, catering shelving provides a durable, easy-to-maintain way to organise food, utensils and work materials.

PVC trolleys can also make it easier to move products, containers and utensils around warehouses, kitchens and other professional facilities.

In every case, it is important to distinguish between items that come into direct contact with food and those designed to organise or equip the surrounding environment. An ingredient container must meet different requirements from a changing-room locker, a shelving unit for storing equipment or a transport trolley.

How to choose the right material

Before selecting a food-grade plastic, businesses must assess the facility’s actual operating conditions. Appearance or a commercial product name alone cannot determine whether a material is suitable.

Type of contact and conditions of use

First, determine whether the product will come into direct contact with food or whether it will simply form part of the food-handling environment. Then consider the type of food, as the material may behave differently when exposed to fatty, acidic, aqueous or dry products.

You should also consider the operating temperature, contact time, cleaning frequency and chemicals used. In professional facilities, it is also advisable to assess the required resistance to loads, impacts, moisture and intensive use.

Documentation and equipment design

Where food contact will occur, businesses should request the relevant declaration of compliance and technical documentation. These documents identify the uses for which the material has been assessed and any applicable limitations.

Finally, the equipment must suit both the cleaning system and the layout of the space. Durable, hygienic and well-designed materials can reduce maintenance requirements and support more efficient organisation.

Why choosing the right materials matters in food environments

Food-grade plastic plays an essential role in many professional environments thanks to its resistance, versatility and ease of cleaning. Businesses can use materials such as food-grade PVC, polyethylene and polypropylene for a wide range of applications, but they must always verify suitability according to the formulation, type of contact and actual conditions of use.

At Decoplastic, we provide functional, hygienic and durable PVC equipment for cold rooms, commercial kitchens, warehouses and other food-industry facilities. Choosing materials that withstand moisture, temperature changes, frequent cleaning and intensive use helps extend equipment life while keeping work areas organised and safe.
