Food contact and container resin

Before a plastic bulk container touches food, ask which resin it is made of, whether that resin and its colour are FDA-compliant for food contact, and get it in writing for the exact model. Don't assume it from the colour or the word "food grade" in a listing.

The two resins you will meet

Most bulk containers are high-density polyethylene (HDPE) or polypropylene (PP). The ORBIS AG4048-32 is HDPE (ORBIS AG4048-32 product page); the MACX macro bin is HDPE (SJF MACX bin listing); the Rehrig Pacific field bin is high-impact copolymer polypropylene with up to 30% recycled content (Rehrig Pacific 40 x 48 field bin page). Both resins are used for food contact. Whether a particular container is suitable depends on the exact compound, the colourant and any recycled content.

Colour is part of the question

Containers are coloured with pigments, and the pigment has to be suitable too. That is why some makers sell an "FDA-approved colour" alongside standard and non-heavy-metal colours, as Rehrig Pacific does for its field bin. If food touches the walls, ask for the food-contact colour, not just any colour that looks clean.

Recycled content

Recycled resin is good for the world and often fine for parts and scrap, but its history is harder to document. Where a container has recycled content and will touch food, ask the maker how that content is qualified.

What sellers say, and what to get

Listings use phrases like "meets USDA/HACCP standards for food product handling", which is how SJF describes MACX bins. That is the seller's statement. For your food-safety file, ask for the maker's own written statement on resin and colour for the model you buy. We get it and attach it to the quote.

Beyond the resin

• Solid walls for anything wet, and to keep fines in.
• Smooth insides and rounded corners so nothing cakes in.
• Lids for storage and transit.
• A washing plan: what cleans the bins, how hot, and how often.

The FDA Food Traceability Rule sets record-keeping for certain foods. A numbered reusable bin can carry a lot code through the plant; ask for numbering if you need it.

What "FDA compliant" means for a container

The US Food and Drug Administration lists which plastics, and which additives in them, may be used in contact with food. A container maker who sells a food-contact model is saying its resin and colourant are made from substances on those lists, for the kind of food and temperature in question. That statement belongs to a specific compound. A container moulded from a different batch or a different colour isn't covered by it automatically, which is why the statement has to be for your model and colour.

USDA and HACCP

Meat, poultry and egg plants answer to USDA as well as FDA, and most food plants run a HACCP plan. A container doesn't "have" HACCP; your plan covers how you clean, inspect and use it. What a container can do is make that easier: smooth surfaces, no crevices, colours that show dirt, and a material your plan already accepts.

Temperature

Polyethylene stays tough in the cold, which is one reason it is used for freezer and cooler bins. Polypropylene can become brittle at low temperatures unless it is a copolymer grade made for impact. If your bins go into a blast freezer or out into winter yards, say so and we check the model is rated for it. Hot washing matters too: ask the maximum wash temperature.

Allergens and segregation

Plants that handle allergens often keep bins for each one, or for raw and cooked product, separate by colour. Order the colours at the start, because adding a colour later can mean a different batch and a new statement.

Inspecting bins in service

A deep scratch or a crack in a food bin can hold product and bacteria that washing won't reach. Inspect bins as they come out of the washer and take damaged ones out of food service; they can often carry packaging or non-food items instead.

Virgin versus recycled

Virgin resin has known history; recycled resin may carry traces of whatever it held before. For direct food contact, most buyers want virgin resin or recycled resin that has been approved for food use.

Metal detection

Some food plants use detectable plastics, with metal particles mixed in so a broken piece is caught downstream. Bins themselves are rarely made this way, but small parts on them sometimes are.

Documents to keep on file

Auditors for food safety schemes, such as those benchmarked by the Global Food Safety Initiative, ask to see a letter of guarantee or compliance statement for every food-contact material. Keep the statement for each bin model in your food safety file, with the date you received it.

Ask early

Request the resin statement before ordering, not after delivery.
