How Can I Keep Products Safe & Fresh?

Products in the food, beverage, hardware and cosmetic industries want their products to be sealed and fresh in the right containers to meet customer needs. To maintain that airtight seal and freshness without any tampering, companies rely on tamper evidence and protection in a wide variety of styles, shapes and sizes.

It is important to understand what a tamper-evident container is and why it matters to products, companies and especially customers.

What Is a Tamper-Evident Container?


A tamper-evident container can be described as a tub-shaped container with a lid that produces a tight seal. This airtight seal is able to keep products safe for consumption and use. To prevent any tampering from occurring, a visible deterrent is put on or around the container.

There are certain components of a tamper-evident container that should be present in order for certain packaging to be considered as such.


What Is Required to Be Considered Tamper-Evident?


According to the Food and Drug Administration (FDA), any tamper-evident container needs to have some form of visible deterrent that can show users that tampering has occurred. Tampering can be anything from physical damage to the packaging or the fact that it has been opened at some point.

These visible deterrents can be seen on a wide variety of tamper-evident products. They include:

Airtight Seal from Container Lid

An "open" tab is commonly found on a tamper-evident tub. It is the area where the lid and container meet to create the tamper-evident airtight seal. It also assists in the opening process.

Tear Strip (Capseals)

Capseals, commonly used on IBC totes and drums, will have a tear strip across. An open capseal is noticeable when the the strip has been removed or pulled.

How Can People Achieve This?

Users can help make tamper-evidence and protection possible by: 

1. Recognizing products have been tampered with.

2. Keeping products safe by putting them in areas they are supposed to be (certain shelves, storage spaces, etc.).

3. Always being on the lookout for objects that may cause tampering, whether by accident or on purpose.


Tamper-Evident Components & Examples


There are a few things that make tamper-evident packaging stand out. Here are some popular components and examples.

The container and lid combine for an airtight seal. Both parts of the packaging need to be used in order to be classified as tamper-evident. One of the most important things that matter to customers is making sure the products they order are fresh and safe for either consumption or use. 

This can be the case for fast-food restaurants handling quick to-go orders or grocery stores and bars having products on shelves to sell. With tamper-evident packaging, it makes it happen.

Some tamper-evident containers come with a tab in the front to show users where it can be easily opened. The container will have a tab near the front that can help users align the lid and tub as well as create the tamper-evident airtight seal by putting the two together.

Tamper-evident tubs are available in different shapes and sizes, all designed to fit various products. Some of the more popular examples include:
