Why Tamper Evident Neck Banding Continues to be a Top Trend in Packaging


One of the most popular trends in the packaging industry is the use of tamper evident neck banding. Especially common for pharmaceutical, food and beverage products, heat shrinkable tamper evident seals offer a number of significant benefits. Below, we'll take a look at the top reasons why tamper evident banding continues to be a foundational packaging method.

Security is Number One

Tamper evident seals serve as a way to ensure consumer safety. For many products such as pharmaceuticals, tamper evident banding is a requirement, as it greatly increases the integrity of the product. The banding helps to prevent opening of the product without detection, as it can’t be resealed once it’s open, without a clear visual indicator. Tamper evident banding, therefore, ensures that the product remains untouched since its bottling, preventing many forms of contamination. 

Consumer Confidence – At the Point of Purchase

Tamper evident bands make products more appealing to consumers. If a customer is purchasing a pharmaceutical or food product, or one that they intend to consume, they want to know that the product is sterile and untouched. Tamper evident banding gives them that peace of mind at the point of purchase when, choices between brands are made. Unlike an inner seal hidden by the cap, when a customer buys a product that has a neck band they can easily tell if it has been opened or not. Consumers can rest assured that the product has not been touched or tampered with at any point since it was packaged.

"Grazing" Prevented

Grazing, or eating foods off the shelf that has not been purchased, is a real problem in many supermarkets. However, tamper evident banding prevents this from being a concern. Not many people are willing to work at breaking a seal to try out a product, and even if they do, employees will be able to recognize that the product has been opened and take it off the shelf. This enables tamper evident banding to serve as both a deterrent to grazing as well as a way to notice when grazing has occurred.  

Maintains Integrity of Packaging  

Tamper evident banding can help improve the integrity of packaging by securing the lid of the package to the container. While this provides security against tampering, it can also help maintain freshness and prevent accidental mishaps in which the lid is separated from the container as well.

Bottle Fill Line Coverage

Tamper evident seals can be applied down the neck of bottles, hiding the fill line. Fill line coverage compensates for the variability of liquid filling machines and container volumes, particularly of glass. Brands don’t want to give consumers the impression that bottles are “under filled” due to package variability. A neck band in this area also can serve as a surface for graphics and marketing design elements such as logos and colors, enhancing package appeal.

Tamper Evident Banding Machinery Capabilities

Any machinery applying tamper evident banding needs to be flexible in order to fit various packaging shapes and sizes. PDC manufactures a broad range of neck banding machinery for the application of heat shrinkable tamper evident seals. PDC tamper evident banding machinery is engineered for maximum flexibility with regard to product shape. Our F Series, for example, is ideal for tapered and straight walled containers used for ice cream, dried fruit, cultured products, and dips; containers that don’t have a shoulder on which the band can rest. Our machines can also produce various types of perforations, from vertical to horizontal and angular, via a range of cut-to-land ratios of perforator blades. It is the perforations that are broken during opening that provide the visual tamper evidence.

By building additional consumer confidence, increasing the security of the product, improving the integrity of the packaging, and more, tamper evident banding continues as one of the most beneficial packaging methods.
