Are RPET Laminated Bags available with zippers?

Hey there, RPET Laminated Bag

If you’re deep in the market for sustainable packaging (or just started dipping your toes into ditching single-use plastics), I’m guessing you’ve stumbled on RPET laminated bags more than once. As someone who’s been supplying these bad boys for over seven years now, I get it—there’s so much confusion out there about what they can actually do, beyond just holding snacks or shipping small items. The question I get asked all. the. time. lately? “Are RPET laminated bags available with zippers?” Let me cut through the noise and give you the real, unfiltered answer—no corporate jargon, no fluff, just what I tell every single buyer who calls my line.

First, let’s get one thing straight: RPET isn’t some new, untested material that only works for basic drawstring totes. RPET stands for Recycled Polyethylene Terephthalate, which means it’s made from post-consumer plastic bottles (think the ones you toss in your blue bin after soda or water). We collect those bottles, shred ’em, wash ’em, melt ’em down, and spin ’em into yarn before laminating them with a thin layer of food-safe polymer (usually LDPE or PP, depending on the bag’s use case) to make it tear-resistant and moisture-proof. That lamination is key here—it’s why people ask about zippers, right? Because not all laminated bags can handle hardware that’s supposed to close them tight.

When I first started making RPET bags back in 2016, zippers were a no-go. We’d mess around with cheap plastic zippers that snapped after a few uses, or metal ones that would scratch the laminated surface and leave little rust spots that ruined the bag’s look. But we listened to our customers—grocery chains that wanted resealable bulk nut bags, small-batch candle brands that needed airtight packaging to keep wax from drying out, even pet food companies that needed bags that could be sealed and reopened multiple times without spilling kibble. So we started testing, and testing, and testing again for two whole years.

Today? Let me be crystal clear: 100% of our RPET laminated bag lines come with zipper options. No fine print, no “only certain sizes.” We have three main zipper styles that work seamlessly with our laminated RPET, and I’ll break ’em down because picking the right one matters a lot more than you’d think.

First up, the standard resealable plastic zipper (you know, the kind you see on snack bags). We use heavy-duty #5 zippers here—way thicker than the flimsy ones on drugstore sandwich bags. Why #5? Because it’s wide enough to stay locked even when the bag’s fully stuffed with, say, 5 pounds of organic rice or a 10-pack of socks. And we don’t use cheap zippers that break at the first tug; we source ours from a manufacturer that’s just as strict about sustainability as we are, so the zippers are either made from recycled plastic too or certified BPA-free. We test every batch by filling a bag with 10 pounds of grain, sealing the zipper, and shaking it upside down for 30 seconds—no leaks, no unzipping, every single time. That’s non-negotiable for us.

Second, we have the Eurostyle zipper, which is perfect if you want a bag that looks a little more polished. It’s a tiny bit sleeker than the standard one, with a little pull tab that’s easy for everyone—including kids or people with limited dexterity—to grip. We use this for our flat RPET laminated bags, which are super popular with cosmetic brands that want their skincare samples to stay fresh, or tea companies that need bags that look good on store shelves. The Eurostyle zipper doesn’t stick out as much, so it doesn’t catch on stuff when you’re pulling the bag off a display. The best part? It’s still 100% compatible with our food-safe lamination, so you don’t have to worry about any weird leaching if you’re packaging edible goods.

Third, and this is the one that surprises a lot of people, we have metal zippers too. Wait—metal on RPET laminated bags? How does that work without scratching? We had to figure that out, obviously. We line the area where the metal zipper attaches to the bag with a thin strip of our laminated RPET (wait, it’s like a little buffer zone) and use a reinforced stitch to hold the zipper in place. No more scratches, no more rust, because the metal never actually touches the main laminated surface. We make these for customers who need something super durable—think construction supply brands that want bags for small hardware parts (screws, nails) that need to stay dry, or outdoor gear companies that want lightweight bags for trail snacks that need to be sealed in wind and rain. A metal zipper RPET laminated bag can take way more abuse than you’d expect; I’ve had one last a full year of being tossed in a truck toolbox and still sealing tight.

But here’s the thing I don’t think enough people talk about: it’s not just about slapping a zipper on any RPET laminated bag. The lamination itself matters, because that’s what the zipper adheres to. If you have a thin, low-quality lamination, the zipper will pop right off after a few uses. That’s why we only use either 2-mil or 3-mil lamination, depending on the bag size and intended use. For smaller bags (like sample-sized bags or snack bags), we use 2-mil—light enough that the zipper doesn’t feel bulky, but strong enough to stay sealed. For larger bags (like 25-pound bulk pet food bags), we bump it up to 3-mil, so the zipper holds even when the bag is fully loaded. We also do a special heat-seal on the zipper area, not just stitching, so there’s no gap between the zipper and the bag that lets air or moisture in. That’s how we keep things airtight for months, not just weeks.

I get it—some people still ask, “Wait, is an RPET laminated bag with a zipper actually more eco-friendly?” Because I know a lot of folks hear “zipper” and think “that’s plastic I can’t recycle.” Let’s clear that up too. All the zippers we use are either made from post-consumer recycled plastic (PCR) or are fully recyclable on their own. The metal zippers? They’re 100% recyclable at standard scrap metal centers, and we even include a little info card in every bulk order that tells customers how to separate the zipper if they want to recycle the entire bag. Plus, since RPET is made from 100% post-consumer plastic bottles, using it for bags with zippers keeps even more plastic out of landfills than basic RPET bags—because they’re reusable way more times (you can seal and reopen a zippered bag dozens of times, whereas a non-zippered heat-seal bag is only good for one use). We’ve had customers tell us their zippered RPET bags are still going strong after two years of being used for bulk groceries, and that’s exactly the kind of circular economy win we’re here for.

Now, I should also mention that we can customize the size, color, and even the zipper pull for you. Want a navy blue RPET laminated bag with a neon green zipper pull for your specialty coffee brand? Done. Want a 10-pound bag of birdseed with a silver metal zipper and a custom logo printed on the front? No problem. We work with every client, from small Etsy sellers to national retail chains, so no order is too big or too small. I’ve had a mom-run candle company order 500 small zippered RPET bags for their soy wax tins, and I’ve had a grocery chain order 200,000 zippered bulk nut bags for their stores. We make it work.

Wait, let’s address the one catch I know is out there: some suppliers will tell you they have zippered RPET laminated bags, but they skip the proper testing. Don’t fall for that. A lot of cut-rate suppliers will glue a cheap zipper to a thin laminated bag, and it’ll fall apart after the first use. We test every single one of our zippered batches before they ship, because our reputation is on the line. I’m not the kind of guy who will sell you something that breaks in your customer’s hands—word of mouth is everything in this space, and I’d rather lose a small order than get a bad review that ruins my business.
