What is R-PET? A clear guide to recycled PET for food packaging

If you sell meat, fish, cheese or ready meals, you've almost certainly held R-PET in your hands, even if nobody called it that. It's that tough, transparent tray under the film on the supermarket shelf. But what exactly is it, is it food-safe, and why are Europe's big brands switching to it? Here's the plain-language version.

R-PET, in simple terms

R-PET stands for recycled PET (recycled polyethylene terephthalate). PET is the same well-known plastic used for decades in water bottles and food trays. "Recycled PET" is that material collected, cleaned and processed so it can be used again, instead of being made from scratch out of virgin, oil-derived resin.

In other words: R-PET is plastic with a second life. The same performance, with a much smaller footprint.

How an R-PET package is made

A good R-PET package isn't simply melted bottles poured into a mould. Quality depends entirely on the process. At EcoPet Europa it works as a single, continuous, controlled cycle:

1. Sourcing — traceable recycled PET flakes arrive from trusted suppliers.
2. Sheet extrusion — the flakes are turned into multilayer PET sheet on a high-capacity extrusion line.
3. Thermoforming — that sheet is heat-formed into precise trays, in more than 150 formats.
4. Quality control and delivery — every batch is checked and shipped to the customer's line.

Because all four steps happen under one roof, there are no gaps in the chain where quality — or supply — can fail.

Is R-PET safe in direct contact with food?

Yes, when it's built properly. The clever part is the structure. EcoPet trays use a three-layer structure:

• A thin layer of 100% virgin PET on every food-contact surface (around 5% each), guaranteeing full food safety.
• A core of up to 90% recycled PET, which gives the tray its body and its sustainability.

This way, the food only ever touches new, food-grade material, while the bulk of the tray is recycled. You get the environmental benefit and full compliance with European regulations on recycled materials in contact with food. PET is also naturally free of substances that migrate into food and offers a good barrier against oxygen and CO₂, so it protects taste and shelf life very well.

Why brands are switching to R-PET

• It tells a better story. "Made with recycled material" is something shoppers notice and value.
• It performs. PET withstands low temperatures without cracking, so it's ideal for chilled and frozen products, and it's compatible with both MAP and SKIN.
• It's future-proof. European regulation keeps pushing towards recycled content. Brands already using R-PET are ahead of the curve, not chasing it.

What almost nobody mentions: consistency

Recycled material is only as good as the discipline behind it. The key question for a packaging supplier isn't "do you offer R-PET?" — almost everyone does today. It's: "can you deliver the same quality, in every batch, on time, every time?" That depends on how much of the process they actually control. A supplier that makes its own sheet from its own material can guarantee a consistency that a company buying finished sheet from third parties simply can't.

That's why EcoPet runs a complete production cycle: so reliability is built into the product, not added afterwards.
