Yes. In fact, Zip Top containers are made from the Platinum Silicone, the most pure Food Grade Silicone available. You can rest easy knowing that Zip Top containers do not contain chemicals or fillers that could leach into your food.
Zip Top containers are 100% platinum-cured silicone ("platinum silicone" for short), the highest grade available that passes all U.S. and European safety standards. It is food safe, microwave safe, freezer safe, and dishwasher safe. Other products may claim that their product is "food safe" but unless it is pure platinum silicone, you should be cautious of how it can be safely used.
Traditional plastic containers are petroleum based and can contain harmful chemicals. Because Zip Top is made from 100% platinum silicone, it is free of BPA, lead, phthalates and PVC. It is also hypoallergenic.
YES! They were designed for the dishwasher, so all Zip Top containers have large rounded corners for easy cleaning. Most importantly, all Zip Tops stay open for better cleaning and drying! They are top or bottom rack safe.
Yes! Zip Top containers are completely microwave safe. And because they do not contain any plastics, they will not leach harmful chemicals when used in a microwave. If you leave the zipper partially or completely closed during heating, be careful when opening the zipper due to accumulated steam.
Most foods will not stain your Zip Top containers. There are a few foods, however, which can stain pure silicone such as tomato sauce, curries, watermelon, cooked carrots and other red/orange foods. Try rubbing with a baking soda and water mixture and let sit for 4 hours. Rinse well and then wash as usual.
Zip Top containers seal differently than traditional plastic zippered baggies which have tiny, hard, flat plastic zippers. Zip Top containers have large, soft, rounded zippers that flex. Because of this, your containers may, at times, leak a small amount of air if squeezed. In addition, once sealed, because of the pull of the wide, rounded opening, air will sometimes want to seep back in. If so, the small amount of air in your Zip Top will act like air trapped in a typical lidded container.
Zip Top containers are designed to hold liquids upright in a kitchen environment. This is why every container says on the back to “keep liquids upright" (which is simple since all Zip Top containers stand up due to their sturdy flat bases). When kept upright, Zip Top containers are completely leak proof. Zip Top containers were never designed, for instance, to fill with water and hold upside down or for taking liquids on the go.
Zip Top containers are not designed for taking liquids on the go. Just like you would typically not take soup in a plastic zippered bag in your backpack, Zip Top containers are designed to hold liquids in a kitchen environment. This is why every container says on the back to “keep liquids upright” (which is simple since all Zip Top containers stand up due to their sturdy flat bases). Zip Top containers are wonderful on the go for leftovers, sandwiches, dry snacks, veggies, fruit, nuts, etc.
In general, no. From our internal testing as well as our personal use over the past year, we have been thrilled with how well the seals hold during typical scenarios such as being knocked over. Because of the flexibility of silicone, they are durable and malleable when sealed. However, as stated in this FAQ, we recommend liquids be kept upright to be safe.
We do not recommend completely submerging Zip Top containers in water for sous vide or other applications. Due to the flexible zipper seal, some water may, at times, seep into a fully submerged bag. However, Zip Top containers are great for steaming and cooking where the zipper seal may fully or partially be left open while heating.
We ship to most countries around the world. We currently ship all orders from our fulfillment center in the United States so international shipping rates could be high. Soon, we hope to open a fulfillment center first in Europe and then in strategic locations around the globe to facilitate more economical and timely shipments. If you sign up for our newsletter, we will alert you when new markets are opened around the world.
Products purchased on our website, ziptop.com, can be exchanged or returned within 14 days of receipt if they are in new, unused condition and in the original packaging. Qualifying refunds are issued for the purchase price and any taxes paid. Shipping is not refunded. If you would like to return an item you received as a gift, it's our pleasure to offer an exchange for an item of equal or lesser value, subject to availability.
Our prices DO NOT include VAT, GST or other country taxes.
Our terms of sale for international orders are FOB destination. This means that you pay all freight and duties or taxes. As we are shipping these products all over the world, it is impossible for us to build in the various duties, VAT and GST tax for each location through Kickstarter.
If you would like to estimate your duties, you can use this online tool (remember to convert the U.S. dollars to your local currency):
For international customers who are required to pay customs, you will receive an email from your local customs authorities asking for payment to have your order processed through customs. Unfortunately, there is no legal way around customs (including marking an order as a gift, which we cannot do). Once you make that payment to the customs broker your order will be processed for final delivery.
The amount you paid for shipping covers our cost to transport your perks to you. Some countries will also assess Duties and Taxes upon entry to your country. This is your responsibility as it varies greatly by country. Please review the detailed information on our FAQ page under the heading of "How are international taxes and duties collected?" so that you are not surprised by these charges.
