When I first started out as an RPET bag supplier three years ago, the most common question I got from potential buyers wasn\u2019t about the material\u2019s sustainability or how much carbon footprint it cuts compared to virgin plastic\u2014it was, \u201cWait, do these recycled plastic bags actually come with zippers? Not just those flimsy drawstrings that snap after two uses?\u201d RPET Bag<\/a><\/p>\n

<\/p>\n

I get it. A lot of people still associate reusable bags with thin, single-use-adjacent tote bags that you grab for groceries and toss in the trunk until they get crumpled beyond recognition. Or, worse, the cheap drawstring bags you get at trade shows that fray after a month of light use. But RPET\u2014recycled polyethylene terephthalate, which is just another way of saying plastic bottles that have been collected, sorted, shredded, melted down, and spun into durable fabric\u2014has come a long way, and so have the closures for bags made from it. Over the last three years, I\u2019ve worked directly with our manufacturing partners in Vietnam and India to test every type of closure under the sun, from heavy-duty zippers to custom drawstrings, and today, I want to break down exactly what\u2019s available, what works for different use cases, and why a lot of suppliers still get this wrong.<\/p>\n

First, let\u2019s clarify what RPET fabric is, because that\u2019s the foundation of every closure we use. Our RPET fabric is made from 100% post-consumer plastic bottles\u2014each yard takes about 15 bottles, so that\u2019s a good chunk of waste that would otherwise end up in landfills or oceans. But unlike cheap fabric made from recycled plastic that\u2019s thin and tears easily, we use a heavyweight 600D RPET polyester for most of our bags; that\u2019s the same denier rating used for many outdoor nylon bags, so it\u2019s tough enough to hold laptops, groceries, or gym gear without stretching. The fabric\u2019s durability is key because a closure is only as good as the material it\u2019s attached to. If the fabric rips when you pull a zipper, that closure doesn\u2019t matter.<\/p>\n

Now, to the core question: yes, RPET bags are absolutely available with different closures. I can count on one hand the number of buyers who only ask for drawstrings, and most of those are looking for basic gym bags or shoe bags. For everything else, from corporate branded tote bags to travel toiletry kits to school backpacks, there are multiple closure options that work just as well (if not better) than closures on virgin plastic bags.<\/p>\n

Let\u2019s start with the most commonly misunderstood closure: zippers. For years, suppliers tried using cheap plastic zippers on RPET bags, and they snapped, got stuck, or pulled away from the fabric after a few uses. So we spent the first year of my company testing different types of zippers to fix that. Today, we use two main types of zippers for our RPET bags, and they\u2019re not the flimsy ones you find on disposable bags. The first is a nylon coil zipper, which is lightweight, flexible, and perfect for tote bags, laptop sleeves, and toiletry kits. We pair 5-coil zippers (the standard size for most everyday bags) with reinforced RPET fabric tape along the zipper edges, so the stress of pulling doesn\u2019t tear the bag. We tested this with 10,000 open-close cycles\u2014way more than the average user would do in a year\u2014and the zippers didn\u2019t budge. The second type is a heavy-duty plastic molded zipper, usually size 8 or 10, which we use for duffel bags, cooler bags, and even bike panniers. These zippers can hold up to 50 pounds of pressure without separating, which is way more than any RPET bag will ever need to hold, and they\u2019re water-resistant too\u2014important if you\u2019re using a bag for beach trips or rainy commutes.<\/p>\n

A lot of people ask if metal zippers work with RPET bags, and the short answer is yes, but with a caveat. Metal zippers add a bit more weight to the bag, and if they\u2019re not coated, they can scratch the RPET fabric over time. We only use metal zippers for very specific cases\u2014like custom branded bags for luxury corporate clients who want a premium look\u2014and even then, we use zinc-alloy zippers with a nylon coating to prevent scratching and to keep the weight manageable. We also make sure to add double stitching around the zipper base, which is a step we had to learn the hard way: our first batch of metal zipper laptop sleeves had a few that came loose because we only used single stitching, so we revised that immediately and haven\u2019t had an issue since.<\/p>\n

Next, drawstrings. I know, I said drawstrings are common, but modern drawstrings for RPET bags are a far cry from the thin, stretchy cotton strings that come on cheap promotional bags. We offer two types of drawstrings for our RPET bags. The first is a flat woven RPET drawstring, which is made from the same recycled polyester as the bag itself. It\u2019s sturdy, doesn\u2019t stretch out, and can hold the weight of a full gym bag without cutting into your shoulder or neck. We also add an adjustable cord lock to every drawstring bag, so you can tighten the top to keep contents secure\u2014something most cheap drawstring bags skip. The second type is a bungee drawstring, which we use for smaller bags like shoe bags or phone pouches. The bungee gives a bit of flexibility, so you don\u2019t have to worry about the string snapping if you yank the bag open quickly, and it\u2019s perfect for casual, lightweight use.<\/p>\n

But here\u2019s a part that a lot of RPET bag suppliers don\u2019t talk about: hybrid closures. We\u2019ve had a lot of success with bags that combine two different closures, because one size never fits all use cases. For example, our best-selling RPET laptop tote has a top drawstring that cinches the bag closed for commuting, plus a hidden zipper inside the main compartment that keeps the laptop secure when you\u2019re walking through a crowd or on public transit. Another popular hybrid is our RPET duffel bag, which has a main zipper for the large compartment, plus a small drawstring pocket on the side for water bottles or keys that you want to grab quickly. We also made a custom order recently for a university that wanted RPET backpacks with a main zipper, a drawstring top for easy access to textbooks, and a small magnetic closure on the front pocket for student IDs.<\/p>\n

I should also mention specialized closures, because RPET isn\u2019t just for everyday bags. We work with outdoor brands that need RPET bags for hiking and camping, and for those, we offer roll-top closures, which are super popular now for water-resistant bags. A roll-top works by folding the top of the bag over three or four times and securing it with side straps\u2014we use RPET straps with plastic buckles, so no virgin plastic, and it creates a completely waterproof seal, which is perfect for hiking gear or beach bags. We also make RPET bags with magnetic closures, which are great for toiletry kits or small crossbody bags. The magnets are strong enough to keep the bag closed when it\u2019s in your purse, but easy to open with one hand, which is a huge convenience for people who travel.<\/p>\n

Now, you might be wondering why more suppliers don\u2019t offer this range of closures. It comes down to two things: cost and expertise. Cheap RPET bags are made with the cheapest possible closures to keep the price low, so they cut corners on zipper quality or use thin drawstrings. And a lot of small manufacturers don\u2019t have the experience testing different closures with RPET fabric\u2014they stick to what they know, which is usually basic drawstrings or simple zippers. As a supplier, we prioritize quality over bulk, so we partner with closure manufacturers who specialize in sustainable materials, not just the standard virgin plastic closures. That\u2019s why we can offer everything from heavy-duty zippers to roll-top closures without driving the price up unreasonably.<\/p>\n

I also want to address a common myth: that using different closures on RPET bags undermines their sustainability. Some people think that adding metal zippers or plastic buckles makes the bag less \u201cgreen,\u201d but that\u2019s not true. All of the hardware we use\u2014zippers, buckles, cord locks\u2014are either made from recycled plastic or recyclable metal, and we design all our bags to be easily disassembled at the end of their life, so you can separate the RPET fabric from the hardware for recycling. In fact, we work with a textile recycling company that takes our old bags, shreds the fabric, and melts down the hardware, so nothing goes to waste. We\u2019ve also found that bags with durable, long-lasting closures actually have a lower environmental impact over their lifetime, because they don\u2019t need to be replaced as often as cheap bags with broken closures.<\/p>\n

Over the last three years, we\u2019ve had hundreds of customers test these closures, and the feedback has been consistent. A corporate client that ordered 5,000 RPET laptop bags with zippers told us that not a single zipper failed in the first six months of use, which is unheard of with their old virgin plastic bags. A school that ordered 2,000 RPET backpacks with hybrid zipper-drawstring closures said that students loved how easy it was to open their bags in the hallway without fumbling with a stuck zipper. And an outdoor brand that ordered roll-top RPET bags for hiking said that the closures worked better than the ones on their previous nylon bags, because the RPET fabric was just as durable and the roll-top sealed tighter.<\/p>\n

At the end of the day, the choice of closure for an RPET bag depends on what you\u2019re using it for. If you need a basic bag for groceries, a drawstring closure is perfect, but if you need a bag for a laptop or travel, a zipper is better for security. If you want something that works for both, a hybrid closure gives you the best of both worlds. And as an RPET bag supplier, we\u2019re always testing new closures to meet our customers\u2019 needs\u2014we just rolled out a magnetic fold-over closure for small crossbody RPET bags, and we\u2019re working on a snap button closure for kids\u2019 lunch bags.<\/p>\n

<\/p>\n

If you\u2019re looking for RPET bags with specific closures\u2014whether it\u2019s zippers, drawstrings, roll-tops, magnetic closures, or something else entirely\u2014we can customize them for you. We work with businesses, universities, outdoor brands, and individual buyers, and we\u2019re happy to walk you through every option, from fabric type to closure style, to make sure you get exactly what you need.
