When a food manufacturer, restaurant, or retail buyer reaches out to my company to source PE cling film, one of the first questions they ask—before pricing, thickness, or roll length—is whether our products meet international standards. It’s a fair question, too: for businesses, compliance isn’t just a box to check; it’s the difference between staying open and facing fines, damaging brand reputation, or endangering customers who rely on food packaging to keep meals safe and fresh. As a supplier of nearly a decade, I’ve walked through every step of how we ensure compliance, and I want to pull back the curtain on what that actually means, because it’s not just about a sticker on a box. PE Cling Firm
First, let’s start with what PE cling film is, for anyone who might be new to the space. Low-density polyethylene (LDPE), which is the core material of PE cling film, is a flexible, lightweight plastic that sticks to itself and surfaces, making it ideal for wrapping food, covering bowls, or securing bulk ingredients. The problem is that not all LDPE is created equal, and standards around the world have evolved dramatically in the last 20 years, driven by research into chemical migration, food safety, and environmental impact. When a buyer asks about compliance, they’re usually referencing three key sets of standards: those from the U.S. Food and Drug Administration (FDA), the European Food Safety Authority (EFSA), and the International Organization for Standardization (ISO). For our part, we design every product to meet all three, because most of our clients sell in multiple regions, and single-region compliance just isn’t enough for a global supply chain.
Let’s break down each standard, because that’s where the confusion often lives. The FDA, for example, regulates food contact materials through 21 CFR Part 177, which specifically covers polymers and their components. Under this rule, any substance that could migrate from the cling film into food must be proven safe at levels that don’t pose a health risk. For years, the big concern was chemical additives like phthalates, which were once used to soften plastics. In the early 2000s, studies linked high phthalate exposure to hormonal disruptions, so the FDA updated its rules to ban certain phthalates in food contact plastics entirely. Our team was one of the first small suppliers to invest in testing to confirm our formulations were phthalate-free—something we still audit every six months, even though the rule is in place.
On the other side of the Atlantic, EFSA has its own set of strict thresholds for chemical migration, especially for substances like bisphenols (though BPA isn’t common in PE cling film, we still test for it) and nonylphenol ethoxylates, which are surfactants once used in cling film manufacturing. EFSA’s approach is more conservative in some ways than the FDA’s: they set “tolerable daily intake” levels that are lower, to account for cumulative exposure from multiple packaging products. A few years back, EFSA revised its guidance on certain plasticizers, and we responded by switching to a new generation of food-safe plasticizers that are approved by both EFSA and the FDA. The key here is that we don’t just meet one standard; we test against both, because a product that’s compliant in Europe might not pass muster in the U.S., and vice versa.
ISO standards add a layer of consistency that’s important for buyers when comparing suppliers. ISO 17299, which covers polyethylene films for food packaging, outlines specific test methods for things like tensile strength (how much the film can stretch before breaking), cling strength (how well it sticks to itself without sticking to food), and water vapor transmission rate (to keep food fresh). A lot of suppliers will say they “meet ISO standards,” but not everyone tests for the same metrics. We run three key ISO tests on every production batch: one for migration of substances into food simulants (like water, 3% acetic acid, and 95% ethanol, which mimic different types of food), one for physical properties that affect usability, and one for labeling accuracy—so buyers know exactly what they’re getting, no hidden defects.
But here’s the thing: standards aren’t static. Every three to five years, regulatory bodies update their guidance based on new research, so being compliant isn’t a one-time achievement. For example, in 2021, the EU introduced a ban on intentionally added microplastics in food contact materials, and while PE cling film doesn’t typically contain microplastics, we had to adjust our manufacturing processes to confirm we weren’t creating microplastic fragments during production or use. That meant investing in new testing equipment that can detect particles as small as 100 nanometers—something most small suppliers can’t afford, but we knew we had to, because our clients rely on us to stay ahead of changes. Last year, we also added testing for PFAS (per- and polyfluoroalkyl substances), even though PFAS aren’t used in PE cling film, because some regulatory bodies are considering adding limits on unintentional PFAS contamination in food packaging. Ignoring that would put our clients at risk, so it was a necessary expense.
I often get asked if “compliant” means a product is 100% safe, and the answer is no—no food packaging can make that claim. What compliance means is that a product has been tested to meet the maximum safe levels set by independent, regulatory bodies, so the risk of harm is negligible. That’s a distinction that’s easy to miss, especially with all the misinformation about plastics and food safety online. Some buyers will come to us saying they saw a social media post that all PE cling film is bad, but when we walk them through the testing data, they realize that most of the “bad” products are unregulated, cheap films made with recycled plastic that hasn’t been cleaned or tested.
Which brings me to recycled PE cling film, because that’s a big growth area right now. A lot of clients are asking for sustainable options, so we developed a line of cling film made with 30% post-consumer recycled PE. The tricky part here is that recycled plastic can carry contaminants from previous uses, like food residues or chemicals, so ensuring compliance is even more important. We work with a certified recycling partner that sorts, cleans, and processes the plastic to meet FDA and EFSA standards, and every batch of our recycled product goes through the same migration testing as our virgin film. We even publish the test results on our website for clients who ask, because transparency is key to building trust.
Of course, no supplier is perfect, and we’ve had a batch that didn’t pass testing a few years back. It was a small order for a local grocery chain, and the issue was a minor deviation in the manufacturing process that caused a small amount of an unregulated plasticizer to be present. We caught it before it shipped, recalled the batch, and adjusted our quality control steps to prevent it from happening again. That’s another part of compliance: having a system in place to catch issues before they reach clients. We have a third-party auditor come in every quarter to inspect our facility and review our testing records, so there’s no way for us to cut corners without being held accountable.
So what does all this mean for a buyer looking to source PE cling film? It means you should ask for more than just a certificate of compliance—ask for the test data. Ask what standards the product is tested against, what substances are screened for, and how often the testing is done. A lot of suppliers will give you a generic FDA certificate, but it might only cover a single ingredient, not the final product. We provide our clients with a batch-specific test report for every order, so they can see exactly what our product meets.
At the end of the day, our job as a supplier isn’t just to sell plastic film—it’s to help our clients keep their customers safe. Whether it’s a small café wrapping sandwiches or a large supermarket chain storing bulk produce, compliance is the foundation of that. If you’re a buyer who’s currently sourcing PE cling film and wants to confirm your products are up to standard, or if you’re looking for a reliable supplier that prioritizes compliance, we’re here to help. We can walk you through our testing processes, share our latest audit reports, and work with you to find a product that meets your specific needs and regulatory requirements.
We believe that compliance shouldn’t be a barrier to sourcing quality packaging, and that’s why we invest in every step to make sure our products are not only up to code, but also transparent, affordable, and sustainable.
