While there have been reports of people finding shards of plastic in their Lays potato chips, it is unclear if the plastic came from the chips themselves or the packaging. Most bags for potato chips are made with three layers of polymer materials, which are a type of plastic. However, companies like Frito-Lay, a division of PepsiCo Inc. that includes Lays, are experimenting with alternative packaging materials that reduce the use of plastic.
| Characteristics | Values |
|---|---|
| Plastic in Lays Chips | There have been claims of plastic shards found in Lays chips bags. However, in one instance, Lays claimed it was an accumulation of potato dust that fell into the fryer. |
| Plastic in Chips Bags | Chips bags typically contain layers of polyethylene and polypropylene, which are types of plastic. These bags are single-use plastic that ends up in landfills or waterways, contributing to microplastic consumption by aquatic life and humans. |
| Alternative Packaging | Companies like Frito-Lay (which includes Lays) and Kettle Chips are experimenting with corn starch and other materials to reduce plastic use while preserving taste. Frito-Lay has introduced compostable and biodegradable bags for some of their products. |

What You'll Learn
Plastic found in Lays chips bags
While Lays chips are made of potatoes, salt, and seasoning, the bags they come in are not plastic-free. In fact, a typical potato chip bag is made up of multiple layers of polymer materials. These include Biaxially Oriented Polypropylene (BOPP) on the inside, which acts as a moisture barrier and is resistant to oils and grease. There's also a layer of low-density polyethylene (LDPE) in the middle, which is resistant to vegetable oils and provides strength and flexibility. The outer layer is made of Surlyn®, a thermoplastic resin, which gives the bag its bright colour.
While these materials ensure that the chips stay fresh and tasty, they also have an environmental impact. Plastic pollution is a significant issue, and chip bags are a contributing factor. Recognizing this, some companies, including Frito-Lay, are experimenting with alternative packaging materials like corn starch and calcium carbonate to reduce their plastic waste.
Despite these efforts, it appears that plastic is still present in Lays chips bags, as evidenced by a recent Reddit post where a user claimed to have found a shard of plastic in their Lays potato chips bag. This incident highlights the potential risks associated with plastic packaging, such as accidental ingestion and injury. It also raises concerns about the potential presence of plastic fragments in other chip bags, underscoring the importance of effective packaging testing to ensure consumer safety.
While it is unclear how prevalent these incidents are, it is essential for consumers to be vigilant and for companies to prioritize the safety and well-being of their customers. It is worth noting that Lays responded to the customer's inquiry, offering an explanation that attributed the shard to an accumulation of potato dust that compressed and fell into the fryer. Nonetheless, this incident serves as a reminder to approach snack foods with caution and to be mindful of the potential presence of foreign objects, including plastic fragments.

Lays chips bags are made of polymers
Lays chips bags, like most potato chip bags, are made of polymers. A typical potato chip bag is made up of multiple layers of polymer materials, each with a specific function. The inner layer is usually made of Biaxially Oriented Polypropylene (BOPP), which serves as an effective moisture barrier and also resists oils and grease. The middle layer is made of low-density polyethylene (LDPE), which is resistant to vegetable oils and provides strength and flexibility to the bag. The outer layer is a thermoplastic resin, such as Surlyn®, which is also strong and flexible.
These polymer materials ensure that the chips remain fresh and tasty, and they also prevent the bag from breaking easily. The packaging is designed to meet the needs of both the food manufacturer and the customers while also adhering to regulatory requirements.
However, there is a growing concern about the environmental impact of these polymer bags. Polymers, like all plastics, are derived from petroleum and do not easily decompose. This has led to a significant amount of plastic waste, with the UN Environment Programme estimating that humans produce about 400 million tons of plastic waste annually. As a result, many snack companies, including Frito-Lay, are exploring alternative packaging materials that are more environmentally friendly.
Frito-Lay, for example, has committed to making all its packaging 100% recyclable, compostable, biodegradable, or reusable by 2025. They have introduced bags made of polylactic acid, derived from corn starch, for some of their products. Other companies, such as Cuétara Foods, are also experimenting with materials like corn starch and calcium carbonate to reduce their plastic waste. These efforts are a response to consumer demands and potential regulations, aiming to create more sustainable packaging solutions for snack products.

Frito-Lay's alternative packaging
Frito-Lay, the North American food division of PepsiCo, has been working on sustainable packaging alternatives. The company has announced its sustainability agenda, PepsiCo Positive (Pep+), which outlines its commitment to creating growth and value while operating within planetary boundaries and driving positive change for the planet and people.
Frito-Lay has set an ambitious goal for its entire brand portfolio: by 2025, it aims to design 100% of its packaging to be recyclable, compostable, biodegradable, or reusable. As part of this initiative, the company has introduced at-home and industrially compostable snack packaging. The Off the Eaten Path packaging, made using PLA, is industrially compostable and produces 60% lower greenhouse gas emissions than traditional packaging. Frito-Lay has also partnered with TerraCycle to collect empty bags for commercial composting, with each returned bag resulting in a donation to Ocean Conservancy.
Frito-Lay's commitment to sustainability extends beyond packaging. The company has invested in a new electric fleet, starting with a pilot Ford eTransit truck, and its Supplier Diversity Program supports diverse-owned businesses by removing barriers and providing mentorship.
In April 2023, Frito-Lay debuted its commercially compostable packaging, made from 85% renewable plant materials, at the Coachella Valley Music and Art Festival. Festival-goers were able to dispose of empty bags in clearly marked compost bins throughout the festival campgrounds. This initiative is a testament to Frito-Lay's commitment to creating a more sustainable food system and driving towards a circular economy.

Plastic waste in waterways
The mismanagement of plastic waste upstream has a direct impact on the amount of plastic observed in rivers. Plastics accumulate in terrestrial and aquatic environments, acting as a long-term source of pollution for freshwater and marine ecosystems even after the primary leakage of mismanaged waste has ended. This accumulation is influenced by factors such as waste generation, population density, and settlement distribution.
The impacts of plastic waste in waterways are far-reaching. Plastic debris injures and kills wildlife, including birds, whales, fish, and turtles, through ingestion, suffocation, entanglement, and internal injuries. It also affects domesticated farm animals and contributes to biodiversity loss by transporting invasive alien species. Moreover, plastic pollution releases carcinogenic chemicals into the soil, which can contaminate groundwater and river systems, posing risks to human health and ecosystems.
Addressing plastic waste in waterways requires a multifaceted approach. It involves reducing the production of plastic products, improving waste management practices, increasing circularity in supply and value chains, and changing consumer behaviour to favour reusable and refillable options. Public and private investments in infrastructure are also crucial for effectively managing plastic waste throughout its lifecycle.

Plastic-free packaging alternatives
While there are no definitive sources confirming the presence of plastic in Lays chips, plastic pollution is a pressing environmental concern. The best way to reduce plastic waste is to adopt sustainable, compostable, and biodegradable alternatives.
Plant-Based Plastics
Also known as bioplastics, these are made from cornstarch and bamboo fibres, which are then converted into polylactic acid. They possess similar characteristics and durability to conventional plastics, and many of them are biodegradable in industrial landfills or home composts. Bioplastics have been used to manufacture drink bottles, food containers, and films.
Hemp Plastics
Hemp plastics are one of the newest innovations in the quest for plastic alternatives. They can be used to create strong and durable packaging materials.
Bagasse
Bagasse is the dry fibrous residue left after sugarcane juice extraction. It is increasingly being used as a substitute for single-use plastic tableware and utensils. Bagasse is biodegradable, compostable, malleable, and relatively more sustainable to produce.
Paper-Based Materials
Paper-based materials offer a shower-friendly and water-resistant alternative to plastic. For instance, beauty companies like Seed Phytonutrients have launched bottles made from recycled paper on the outside and recycled plastic lining inside, reducing plastic content by 60%.
Aluminum and Cardboard Packaging
Some companies, like Bee Your Organics, use aluminum bottles and renewable cardboard boxes for their health and beauty products. They also offer refill services to ensure that containers are not single-use.
Eco-Friendly Accessories
Brands can adopt eco-friendly accessories like custom stickers, paper-based water-activated tape, and shipping labels on recyclable liners to enhance the sustainability of their packaging.
These alternatives can help reduce plastic pollution and its detrimental impact on the environment, contributing to a more sustainable future.
