Food-grade plastics are deemed safe for contact with food and beverages
Food-grade plastics are plastics that are deemed safe for contact with food and beverages. They are used in the manufacturing, packing, packaging, storage, and transportation of food and drinks. Food-grade plastics have a certain level of purity and do not contain dyes or recycled materials that could be hazardous to humans if consumed.
Some common food-grade plastics include rPET (recycled polyethylene), PP (polypropylene), and rHDPE (recycled High-Density Polyethylene). Polypropylene, for example, is often used for single-serve containers like yoghurt cups and is microwave-safe and non-volatile, meaning it will not react with any type of food stored in it. Polyethylene Terephthalate (PET), on the other hand, is used for larger soft drink bottles and peanut butter jars and is unique in that both virgin and recycled PET are considered food-grade plastic. It can repel microorganisms and is non-corrosive.
Food-grade plastics can be recycled, but there are some challenges. For instance, rHDPE must be reviewed on a case-by-case basis by the FDA because it can become unsafe for food contact during the recycling process. However, recent technological advancements have made it much easier to recycle rHDPE into food-grade recycled plastic. Another challenge is that, according to EU legislation, recycled input waste must be sourced from at least 98% former food contact packaging, but there is no pre-separated post-consumer collection system in most of mainland Europe.
Despite these challenges, there is a growing demand for recycled food-grade plastics. Surveys show that customers have positive feelings towards companies incorporating more recycled plastic in their packaging and are more likely to buy products with recycled plastic packaging. Additionally, companies like Coca-Cola and Unilever have committed to reducing their use of virgin plastic in their packaging.

Food-grade approval requires recycled input waste be sourced from >98% former food contact packaging
Food-grade virgin plastic is commonly used in food packaging. However, there is a growing demand for recycled plastics in the industry. The use of recycled plastics in food packaging requires approval from regulatory bodies such as the European Food Safety Authority (EFSA) and the United States Food and Drug Administration (FDA). These agencies ensure that recycled plastics intended for food contact applications meet stringent safety standards, particularly regarding potential contaminants from post-consumer waste.
To achieve food-grade approval in the EU, recycled input waste must be predominantly sourced from former food contact packaging. Specifically, EFSA requires that no more than 5% of the plastic waste input used for recycling originates from non-food contact applications. This translates to a requirement that at least 95% of the recycled content come from former food packaging. EU legislation further raises this threshold, mandating that recycled input waste be sourced from >98% former food contact packaging for food-grade approval.
The high standards for food-grade recycled plastics aim to prevent contamination and protect consumer safety. Any contaminants remaining in the packaging could be harmful to human health. To address these concerns, companies employing recycled plastic for food-contact applications in the United States must submit detailed descriptions of both the waste source and the recycling process. They are also required to provide results from tests that prove the elimination of possible contaminants.
The stringent requirements for food-grade approval pose challenges for the industry. The low volume and quality of post-consumer waste, along with the costly technologies needed to eliminate contaminants, hinder the widespread adoption of recycled plastics in food packaging. However, advancements in technology, such as NEXTLOOPP's use of UV-fluorescent markers, offer innovative solutions for identifying and separating food-grade packaging. These developments hold promise in transforming the landscape of recycled food-grade plastics and contributing to a more sustainable future.
