Takeout Seals That Stick: How to Choose the Right Tamper-Evident Labels

Take a look at your last few takeout orders—you’ve probably noticed something they all have in common. Just about every delivery, from big-name chains to neighborhood spots, comes with a tamper-evident seal. And it’s no coincidence. These simple stickers have become the industry norm because they work.

When a customer opens their delivery bag, the first thing they notice isn’t the food—it’s whether the package looks sealed and safe. Tamper-evident labels are designed to give that peace of mind. They show that the food hasn’t been touched or opened since it left the restaurant. If someone tries to peel it off or open the container, the label breaks, leaving visible damage or a “void” message. It’s a simple but powerful way to say, “We care about your safety.”

With more people ordering takeout than ever, especially through third-party apps, food businesses need a reliable way to protect their orders in transit. For example, 2-inch round "SEALED FOR SAFETY" stickers are perfect for sealing paper bags or clamshell boxes in fast-casual restaurants. Direct thermal tamper-evident labels let restaurants print order numbers or timestamps directly on the spot—great for high-volume ghost kitchens. For oily or cold-packaged foods, waterproof BOPP seals ensure the sticker stays in place, even on greasy burger wraps or chilled dessert boxes. Brands looking to stand out often use custom logo labels on kraft paper or matte film to reinforce a premium, eco-friendly identity.

Tamper-evident labels don’t just help prevent contamination or tampering—they also send a strong message about your brand’s professionalism and attention to detail.

In the U.S., takeout seal stickers—also known as tamper-evident labels—have become standard in restaurants, cafés, and delivery services. A quick look at any food delivery bag today will show you how common these labels have become. Depending on the shape, material, and purpose, these stickers can be grouped into several types:

Color Seal Labels
Colorful labels do more than just seal a package—they also help your brand stand out. Available in red, blue, green, orange, and other eye-catching shades, these seals are often printed with messages like “SEALED FOR DELIVERY”, “TAMPER EVIDENT”, or custom logos. Many of them are tamper-proof by design: they break easily when torn or display a “VOID” message when removed. Some are compatible with direct thermal printing for adding order numbers or timestamps. These colorful options are ideal for restaurants using third-party platforms like Uber Eats or DoorDash and looking to improve both safety and brand visibility. We recommend Brother color continuous labels . You can customize label length with them, which is perfect for takeout food that need longer and narrow labels.

Round Seal Labels
Round stickers (usually 1.5"–3" in diameter) are commonly used to seal paper bags, drink lids, or small takeout boxes. Many carry messages like “SEALED FOR SAFETY” or “THANK YOU.” They’re compact, affordable, and don’t take up much visual space—perfect for cafes, sandwich shops, or bubble tea stores.

Rectangle or Strip Stickers
These long, narrow labels—such as 1" x 3" or 2" x 6"—cover a wider area, providing more secure adhesion. Some come with perforated lines so customers can easily tear them when opening a meal box. These are commonly used by meal prep services, bento-style packaging, or home-cooked delivery businesses.

Custom Branded Seals
Looking to promote your restaurant while securing your packaging? Custom-printed seals let you add your logo, contact info, or even QR codes. Materials range from glossy or matte paper to waterproof PET film and kraft paper. These are perfect for independent eateries or small chains looking to leave a lasting impression.

Greaseproof and Water resistant Labels
For oily, steamy, or refrigerated foods, waterproof seals are a must. These are made from synthetic materials like BOPP or PET, which resist wrinkling and falling off. They're ideal for fried chicken, soups, or desserts stored in coolers.

Drink Seals and Straw Hole Stickers
To-go beverages often use small round or strip seals to cover straw holes and lids. These prevent spills and show if someone has already inserted a straw. Popular for bubble tea, juice, and coffee shops, some even use shrink-wrap film or full cup seals for added protection.

Each of these types serves a specific purpose—and with the right choice, your takeout not only stays secure but also reinforces your brand’s quality and care.

Before applying a seal, always make sure the surface is clean and dry. Grease, condensation, or crumbs can weaken the adhesive and cause the label to peel off during transit. A quick wipe with a paper towel can go a long way in helping the label stick properly.

When placing the seal, apply firm pressure with your fingers to secure it in place. This simple step helps the adhesive bond better to the packaging surface, especially on materials like kraft paper or plastic containers.

Be thoughtful about where you position the seal. Place it across the main opening of the bag or box—like over a folded top or container flap—so that any attempt to open it breaks the label. This gives the customer instant visual proof that their food hasn’t been tampered with.

Try not to overstretch the label when applying it. Some tamper-evident seals are designed to tear easily, and pulling too hard might cause premature breakage. A gentle, even application works best, even during a busy lunch rush.

These small tricks may seem simple, but they can improve your packaging presentation and help your seals hold up better during delivery.

Tamper evident labels have become a more and more important role in today’s takeout industry. Like what mentioned earlier, though not a legal requirement, they are required by main good delivery platforms. They are easy to make, help ensure food security during the delivery, and reduces the risk of food being tampered with or stolen. In turn, this helps prevent disputes between customers and restaurants and create a smoother, more trustworthy delivery experience.
