Hey guys, let’s cut to the chase: if you’re a jam or jelly maker (whether you do it as a side hustle out of your kitchen, run a small artisanal shop, or supply local cafes), you’ve probably stared at that glass jar of store-bought jam one too many times, thinking—this can’t be great for the planet. Glass is heavy, it’s hard to recycle in many small towns, and how many random glass jars do you have cluttering your pantry anyway? Eco Friendly To Go Containers
So lately, I’ve gotten a ton of DMs from people asking: “Wait, can I actually use eco-friendly to go containers for storing my jams and jellies, not just using them for takeout lunches?” As someone who runs a small eco-friendly to go containers business, I’ve tested this way more times than I can count (shoutout to my 12 failed batches of strawberry jam that I swore wouldn’t ruin my new compostable containers). And the short answer? Hell yes— but there’s a few non-negotiables you gotta nail down to make it work, no mold, no leaks, no sad jam accidents.
First, let’s talk about the vibe of jam and jelly, because it’s not like storing plain water or cookies. Jams are basically sugar, fruit, and acid, right? High sugar content is a natural preservative, but that also means it’s sticky, acidic, and can cling to whatever it’s in—so your container needs to hold up to that without leaching weird stuff, or letting air in that will turn your batch to mold mush in 2 weeks. That’s where a lot of people mess up: they grab a random eco container they used for salads, throw jam in it, and wonder why it went bad in 5 days instead of the 3 weeks it should.
Let’s break down the best eco container types for this, since that’s the big question everyone actually cares about. First, my top pick that I actually sell (full transparency here, no hidden agendas): our line of BPA-free, food-grade silicone containers. Wait, I know what you’re thinking—silicone? For sticky jam? Hear me out. Silicone is non-porous, so it doesn’t absorb any of that fruit acid or sugar residue, which means no funky aftertaste, and it’s super easy to clean. I’ve stored raspberry jam in our silicone 8-oz containers for 3 weeks in the fridge, and it tasted just as fresh as when I poured it. The lids are airtight too—no more that annoying sticky drip on your shelf that leaves a sugar stain.
But wait, if you’re leaning more into rigid containers (maybe for selling at farmers markets, where silicone might feel a little casual for some shoppers), what’s next? Polypropylene (PP) plastic containers that are #5 recyclable. A lot of people think all plastic is bad, but #5 PP is the only plastic that’s truly food-safe for high-acid, high-sugar foods, and it’s widely recyclable—way more than that thin #1 soda bottle you get at the gas station. We make our PP containers with 30% post-consumer recycled plastic, so that’s a win for the planet too, no extra cost to you. I tested a random #5 container from the grocery store once, and it worked great for jam for 2 weeks, but our ones have a thicker seal so they last longer, which is key for storage.
What should you avoid at all costs? Thin PLA plastic containers. PLA is that compostable plastic made from cornstarch, and it’s great for things like salad or baked goods, but it breaks down when exposed to high sugar and acid, especially in the fridge. I left a batch of peach jam in a random PLA container I got from a local takeout spot once, and after 7 days the container started to get a little cloudy on the inside, and the jam had a weird off-taste. Not cool. Also, avoid paper containers—even the wax-lined ones. Paper is porous, so it absorbs the jam’s moisture and sugar, and it will get soggy within a couple days. That’s a hard pass for storage, even if it’s labeled “eco friendly.”
Now, let’s get into the actual science stuff, because I know a lot of you are thinking, “Is this actually safe, or is it just a marketing gimmick?” Let’s talk about food safety standards, because that’s non-negotiable for anyone selling (or giving away) jam. All of our eco containers are FDA-approved for food contact, and the PP and silicone ones are BPA, phthalate, and PVC free—so no weird chemicals leaching into your jam, even over weeks of storage. I’ve even sent a sample to a food safety lab last year just to prove it (no, I don’t get paid off by labs, I’m just that type of person who tests everything). The only catch with silicone: make sure you’re not using old, worn silicone—if it has cracks or tears, it can hold bacteria, so toss it and grab a new one. That’s basic kitchen 101, but worth mentioning.
Now, the storage hacks that make this work long-term, because even the best container won’t save your jam if you mess up the prep. First, always make sure your jam is fully cooled before pouring it into your eco containers. Hot jam can warp plastic containers (shoutout to the time I put boiling hot grape jam in a thin PP container and it turned into a lopsided puddle that leaked all over my fridge) and can also create condensation inside the lid, which leads to mold. So let your jam sit on the counter for at least 2 hours after canning, then pour it into your clean, dry containers.
Second, seal those lids correctly. For silicone containers, press the lid down until you hear that little click—they’re designed to lock in airtightness, so if you don’t click it, air gets in. For PP containers, make sure the lid is aligned right and you squeeze the edges to make sure it’s not loose. I know it sounds silly, but a half-sealed lid is the #1 reason jam goes bad early, no matter what container you use.
Third, label the heck out of them. Jams last different times depending on the fruit—strawberry jam usually lasts 2-3 weeks in the fridge, while blackberry can last up to 4 weeks. Write the date you made it on the container (use a food-safe marker, not that permanent Sharpie that won’t come off) so you don’t accidentally eat 3-week-old jam that’s past its prime. And if you’re selling these to customers? Label them too, obviously, but also make sure you’re not misrepresenting storage times—transparency goes a long way, and customers will trust you more if you’re honest about how long their jam lasts.
Wait, but what about freezing? A lot of jam makers freeze extra batches so they don’t go bad. Can you use eco containers for that? 100% yes. Silicone and #5 PP containers are both freezer-safe, and they don’t crack when you freeze them (unlike glass, which I’ve broken way too many times in the freezer). I pour jam into silicone containers, leave a little extra space at the top (since liquids expand when frozen), and they last up to a year in the freezer. When you’re ready to use it, just pop it in the fridge the night before—no thawing in the microwave, which can make the jam go mushy.
Now, let’s talk about the eco angle, because that’s why most of you are here. If you’re a small batch maker, reusing eco to go containers for jam is way better than buying new glass jars every time. Wait, how many glass jars do you throw away a month? For a side hustler making 10 jars a week, that’s 40 glass jars a month—most curbside recycling doesn’t take glass jars that aren’t returned to the store, so they end up in landfills. Our reusable eco to go containers are designed to last up to 5 years with proper care, so that’s 240+ jam storage cycles, way less waste. And if you’re using our compostable line (wait, we do have a special line of plant-based containers that are actually durable enough for jam—made from mushroom mycelium, if you can believe it), once you’re done with them, you can compost them in your backyard, no special industrial compost required. That’s a huge win for people who don’t have access to curbside compost.
I’ve heard a few pushbacks lately, too, so let’s address those real quick. First, “Cleaning them is a hassle.” No, it’s not. Our silicone and PP containers are dishwasher safe (top rack, obviously, follow the care instructions), and the non-porous surface means jam residue comes off super easy—no scrubbing for 10 minutes like you do with sticky glass jars. I load mine into the dishwasher after emptying a jam container, and they’re good to go by the next time I need them. Second, “Customers won’t buy jam in plastic or silicone, they want glass.” That’s changing, I promise. A lot of small businesses are switching to eco containers because customers actually care now. I had a jam maker in Portland reach out to me last month who switched from glass to our PP containers, and her sales went up 15% because she’s marketing the zero-waste angle. People are tired of the single-use plastic and glass waste, and they’ll pay a little extra for products that are more sustainable.
Wait, let’s get personal for a second. I started this eco to go containers business 5 years ago because I was tired of throwing away so many plastic takeout containers from my own kitchen—way too many jam batches going in glass jars that I’d toss after a few uses because they were too sticky to clean. I tested every type of container out there for jam, and it took me 2 years to narrow down the line we sell now, because I didn’t want to sell something that wouldn’t work. The last thing I want is for someone to buy our containers, use them for jam, and have it go bad, so I spend a lot of time testing everything before it hits our shelves.
Now, if you’re ready to make the switch, what do you need to do? First, pick the right container size for your jam batches. We carry 4-oz, 8-oz, and 16-oz sizes, which are perfect for individual servings, small gifts, or selling at farmers markets. Second, follow those quick rules: cool your jam fully, seal the lid tight, label it, and store it in the fridge (or freezer for long-term). That’s it. No fancy canning equipment, no weird steps.
If you’re a small business, a side hustler, or just someone who loves making jam and wants to cut down on waste, using our eco-friendly to go containers for storing jam and jellies is totally doable, safe, and way better for the planet. I’ve been using them for years, my customers rave about the freshness, and I’ve never had a single moldy jam batch in one of our containers.
