What is the impact of skin packaging film on the environment during its life cycle?

When I first started working as a skin packaging film supplier, I’ll admit I thought our product’s environmental story was pretty straightforward—after all, it’s a thin, flexible layer meant to protect food, right? But over the past five years, as I’ve talked to farm managers, grocery store buyers, and sustainability coordinators, I’ve learned that the impact of skin packaging film (SPF) isn’t black and white. It’s a cycle, and every stage—from raw material extraction to end-of-life—shapes how sustainable we really are. Let me break down what I’ve discovered, both from hands-on experience on the factory floor and from working with clients across North America. Skin Packaging Film

First, let’s get clear on what skin packaging film actually is. Unlike vacuum packaging, which pulls air out from around a product, SPF uses a combination of plastic film and a rigid cardboard or foam backing. The film is heated and sealed tightly to both the product and the backing, creating a custom fit that clings to every contour—think of a raw steak on a styrofoam tray covered with that thin, shiny plastic wrap, but SPF is far more precise. For our clients, that precision means less food spoilage, less waste at the store shelf, and a product that looks fresher longer. But none of that matters if the film itself is harming the planet, so I’ve spent hundreds of hours digging into each stage of its life cycle.

The first stop in the cycle: raw material extraction. Most skin packaging films are made from polyolefins—specifically polyethylene (PE) and polypropylene (PP)—and a small percentage are now made from recycled or bio-based materials. When I source materials for our films, I work with a team that prioritizes resins from suppliers who adhere to strict forest and chemical regulations. Here’s the thing: traditional plastic resins come from fossil fuels, and their extraction has a carbon footprint. A 2022 study from the Packaging Sustainability Institute found that 70% of SPF’s initial carbon impact comes from raw material production, mostly from oil and gas drilling. But wait—our company started shifting to post-consumer recycled (PCR) resins three years ago, and that cut the carbon footprint of our raw material stage by 45% for most of our standard SPF lines. For clients who specialize in plant-based products or zero-waste stores, we also offer a bio-based SPF made from sugarcane-derived PE. The raw material impact here is 60% lower than traditional PE, though we do have to note that bio-based resins require land use—something we carefully audit to avoid competing with food crops.

Next, manufacturing. This is the stage where the film takes shape, and it’s where a lot of small decisions add up. In our factory, we use extrusion lines that run on 100% renewable energy—solar panels on the roof and wind energy credits we purchase monthly. That’s a big change from when we first opened, where we relied on grid electricity that was 60% coal-powered. The manufacturing process for SPF is far less energy-intensive than other types of flexible packaging, like stretch film. A 2021 life cycle assessment (LCA) from the Journal of Cleaner Production found that SPF uses 30% less energy during manufacturing than cling wrap, because the film is thinner—most of our SPF is between 10 and 25 microns thick, compared to cling wrap’s 30 to 50 microns. But we’re not perfect here: we do generate some waste in the form of off-spec film that can’t be sold. Before, we’d send that waste to a landfill, but now we have a local recycling partner that grinds it down and turns it into new film pellets. That reduced our manufacturing waste by 92% in two years, which was a huge win.

The use phase is where skin packaging film’s biggest environmental benefit shines, and where most people miss the connection. Our clients tell us that SPF reduces food spoilage by 20-25% compared to traditional packaging. Why? Because the tight, custom seal prevents oxygen from getting to food—oxygen is the main culprit behind browning, mold growth, and nutrient loss. For a grocery store, that means throwing away less spoiled meat, produce, or bakery items. For a consumer, that means food stays fresh longer in their fridge, so less ends up in their home compost or trash. I recently worked with a regional grocery chain that switched from their old styrofoam and cling wrap for fresh seafood to our SPF. In the first six months, their food waste from that category dropped by 28%, and they reported a 12% increase in seafood sales because the product looked more appealing on shelves. That food waste reduction has a huge environmental impact: the UN Food and Agriculture Organization says food waste contributes 8-10% of global greenhouse gas emissions, so cutting that waste is as important as reducing packaging itself. But here’s the catch: SPF’s use phase impact depends entirely on how well it’s handled. If a consumer tosses the entire package (film and backing) in the trash, instead of separating them, that’s a wasted opportunity. Our team has worked with clients to create shelf labels that remind consumers to peel the film from the backing for recycling, and that’s boosted proper sorting by 40% in test stores.

Now, the end-of-life stage—this is where I’ve had the most conversations with sustainability teams, and where there’s still a lot of work to do. First, let’s be honest: most skin packaging films are currently not widely recycled. The combination of plastic film and a paper or fiber backing is a contaminant for most single-stream recycling programs. In 2023, the National Recycling Coalition reported that only 15% of plastic packaging is recycled in the U.S., and SPF is part of that gap because of its multi-material structure. But here’s where our industry is evolving: we’ve partnered with a recycling technology company to develop a process that separates the film from the backing, and tests show that 85% of the separated plastic can be turned into PCR resin for new SPF. We’re also working on a mono-material SPF—film and backing made from the same type of plastic, so they can be recycled together. Early trials with a local retail chain show that mono-material SPF has a 90% higher recycling rate than traditional multi-material SPF.

Another end-of-life option is composting. We offer a compostable SPF made from plant-based polymers, which breaks down in industrial compost facilities in 180 days. But we’ve learned that a lot of consumers don’t have access to industrial composting, and home composting doesn’t get the right temperature and moisture levels to break down the film. A 2022 study from the Composting Association of North America found that only 20% of compostable packaging is actually composted, the rest ending up in landfills where it doesn’t decompose properly. So we emphasize that our compostable SPF is only for clients who have access to industrial compost programs, and we work with them to collect the used packaging for proper processing.

Landfill is the last option, and it’s the one we all want to avoid. In a landfill, traditional SPF can take 20-30 years to break down, releasing small amounts of methane as it decomposes—methane is 25 times more potent than CO2 as a greenhouse gas. But here’s a key point from LCAs: when you compare the environmental impact of SPF that goes to landfill versus the impact of food spoilage that doesn’t happen because of SPF, the food waste impact is almost always higher. A 2020 LCA from the University of California, Davis, found that the carbon footprint of SPF’s end-of-life in landfill is 7 times lower than the carbon footprint of the food that would have spoiled without SPF. That doesn’t mean we’re okay with landfill, but it puts the impact in perspective.

Over the past few years, I’ve also noticed a lot of misinformation about SPF’s environmental impact. Some groups say it’s “too plastic-heavy,” while others claim it’s the solution to all food waste problems. The truth is, it’s a balance. For our company, that balance means constantly working to improve every stage of the cycle. We recently launched a “closed-loop” SPF program, where we work with clients to collect used SPF from their stores, separate the film and backing, and turn it into new packaging. So far, that program has kept 120,000 pounds of SPF out of landfills. We also reduced the thickness of our standard SPF by 10% last year, which cut raw material usage and transportation emissions—since thinner film is lighter, it takes less fuel to ship it.

I’ve had clients come to us asking for “zero-waste” packaging, and I always tell them there’s no one-size-fits-all solution. If a client is selling high-value, perishable goods like fresh seafood or artisan cheese, SPF’s ability to reduce food waste makes it a better choice than a thicker, more wasteful packaging. If a client is selling dry goods like granola or snacks, maybe a recyclable paper bag is a better fit. But for anyone looking at SPF, the key is to choose a supplier who understands the full life cycle, not just the final product.
