The U.K. postal service has implored its public to stop mailing empty potato chip bags addressed without an envelope after a surge in chip bag mailings was encountered by its courier offices. The mailings are part of an environmental campaign urging the most popular brand of British crisps, Walkers, to reevaluate its plastic packaging. Walkers, owned by PepsiCo, is being met with a petition signed by more than 310,000 people and an online campaign that is sending unknown numbers of empty bags right to the company’s doorstep.

Twitter is buzzing about the environmental activists, who have been posting pictures of themselves mailing the empty packets of chips through the Royal Mail service. The rebels are using the hashtag #PacketInWalkers to comment on the company’s latent efforts to revamp its packaging. An emailed statement from a Walkers spokesperson, released by CNN, stated, “We have received some returned packets and recognize the efforts being made to bring the issue of packaging waste to our attention. The returned packets will be used in our research, as we work towards our commitment of improving the recyclability of our packaging.” The company has announced that it plans to achieve plastic-free packaging by 2025.

.@walkers_crisps 2025 is too long to wait for you to use plastic free packaging. It’s just not good enough. You produce 4 billion packs per year. I’m sending these back to you so you can deal with your own waste. #PacketInWalkers pic.twitter.com/S13uiZXpdx — Jarred Livesey (@Jaz_Livesey) September 22, 2018

For many campaign participants, such as Jarred Livesey, the commitments are vague and inadequate. “2025 is too long to wait for you to use plastic free packaging. It’s just not good enough,” he commented on Twitter last week. Despite PepsiCo working on a pilot project in the U.S., India and Chile that features compostable packaging, consumers are adamant about stopping the polluters as soon as possible.

Lisa Ann Pasquale went a step further in her Twitter commentary, suggesting, “What if — instead of buying crisps and posting the packages back to @walkers_crisps — we just save our planet AND cholesterol levels by not buying crisps… .” Pasquale makes a sound argument, considering the 11 million bags of potato chips Walkers produces daily in order to keep up supply for its spud-loving consumers, who consume approximately 6 billion packs of chips a year.

The Royal Mail service is caught in the cross-hairs of this environmental argument. Bound by U.K. law to treat the empty potato chip bags as mail as long as they are properly addressed, there is not much else the national communications carrier can do. “If an item is addressed properly and carries the correct postage, then Royal Mail is obliged by law to handle and deliver the item to the stated address,” a Royal Mail spokesperson told CNN. “If they are taking part in this campaign, we would urge them to put crisp packets in an envelope before posting,” because improperly packaged bags could cause delays or be tossed from the sorting sequence.
