Keep Containers Tight & Tamper Free with Tamper-Evident Packaging!

When companies in the food and beverage, personal care and pharmaceutical industries rely on keeping items fresh, the airtight seal with tamper-evident packaging can work for food, beverages and other products. Tamper-evident packaging works to ensure that no one has tampered with the product inside and allows for safe consumption.

There are containers, caps and other packaging options available that have tamper-evident capabilities. Read more about what tamper-evident packaging is, how different industries rely on them and how exactly they can keep your products secure.

What Is Tamper-Evident Packaging?

Tamper-evident packaging is designed to both produce a tight seal that keeps products safe for consumption and let users know that the container or product has not been tampered with. Whether the seal forms from a cap or a container, tamper-evident packaging has a distinct way of showing users that tampering has occurred. Tampering can be a container being opened before using or noticeable damage (a tear to the container or seal).

Closures, containers and pails are popular choices for tamper-evident packaging. Here are some popular applications across industries.

Tamper-Evident Food Containers

Tamper-evident packaging is a popular choice in the food industry. Outside of being used for fast food to-go orders, these containers are available in square, round and rectangular sizes. Additionally, the containers are commonly used in grocery stores, restaurants and bars. 

Tamper-evident containers are commonly made of polypropylene (PP) plastic, which offers good impact resistance and some hot fill applications. The air-tight containers are used with plastic container lids to create a seal that keeps the food and other products fresh, essential for repeat purchases. Tamper-evident containers are also popular due to their in-mold labeling capabilities, opening the door for companies to creatively promote brands with a cost-effective option.

Some beverage bottles are designed to work with tamper-evident caps to hold and keep a wide variety of beverages fresh, from teas and cold pressed juices to water and milk. There are different bottle styles available ranging from classic round and square styles to bullet and rectangular.

One of the most popular examples of tamper-evident beverage caps is a ratchet cap. Commonly used on top of milk jugs, it is tamper-evident due to the ring on the bottom of the cap. When the ring is separated from the cap, it is a clear indication that the jug or bottle was previously opened.

Industrial Plastic Pails & Lids

Most plastic pails are widely considered to be tamper-evident when paired with the right lid. A classic example of a tamper-evident lid has a tear tab or tear strip.

It is important to keep in mind that when the tear tab has been removed, it will not have the same sealing and tamper-evident capabilities. This type of pail lid is made of high density polyethylene (HDPE).

Capseals are commonly sized at 3/4" and 2" to work with most drum and IBC tote fittings. Some capseals require crimping tools in order to have a secure fit on all sides and allow for tamper-evident protection. They are available in a wide variety materials and colors.
