It is necessary for many different industries to prohibit unauthorized access to contents in bags. Tamper evident is a term used to describe a product or process that protects an object with seals, markings, or other resistant techniques.
The purpose of these features is to protect the integrity of the contents and ensure that the consumer or end user receives the bag in its intended form. Many tamper evident bags are designed to reveal if they have been inappropriately opened so that action can be taken right away.
This article will discuss the various types of tamper evident technology used in bags and which types are most frequently used by different industries.
Some tamper evident bags, envelopes, and labels are made with void seals so that when the seal is removed, the word “void” appears and is left behind. These types of bags are often used by retailers who are shipping electronics and other valuable goods. They are particularly useful if a warranty applies to the product contained inside the bag. Void seals are often used on packages, plastic containers, and steel drums and are able to stick on a variety of surfaces.
Another great way to keep your contents safe and out of the wrong hands is to buy tamper evident bags with thermochromic ink. This type of technology verifies the quality of a sealed package by applying heat to form a seal. Upon inspection of the bag, you will be able to determine seal quality and whether it has been previously opened. It is common for bags with thermochromic seals to be tested for quality verification with non-contact and non-destructive techniques. These types of seals can useful for individuals who work in the pharmaceutical industry, for example.
In addition to these seals, tamper evident deposit bags are often made with graphics like webbing and gridding. This type of technology is often utilized by individuals who are transferring cash in the banking and retail industries. Both webbing and gridding provide extra strength and durability for transfer bags to ensure that they stay closed and do not rip or tear to expose the contents. For this reason, it’s important to look for tamper evident bags with webbing or gridding if you work in law enforcement and are handling evidence.
Tear tape technology is often used to address the risk of tampering, authentication, and product coding. Some packaging materials use tear tape because it makes it impossible to remove the tape without destroying the entire package. Since it is not possible to open and reseal these packages without detection, it becomes very obvious that the integrity of the bag has been compromised. This type of technology is often used in the pharmaceutical industry to ensure that a patient receives the drug or medical product in its original form.
