Why the Size of Your Evidence Bag Matters

June 24, 2020

When police officers are called to the scene of a crime, investigating the scene and interviewing victims and witnesses are standard components of the job. The other crucial element is gathering evidence. As a result, every law enforcement officer understands the importance of a quality evidence bag when collecting data from a crime scene. 

Risks of Collecting Evidence

The risk of damaging evidence or its potential for tampering means that you need a reliable bag that is strong enough to resist simple tears and rips that could hinder an investigation and subsequent criminal prosecutions. Placing multiple pieces of evidence in a single bag, for example, will not only cause cross-contamination, but it can lead to damage, thereby hindering any needed evidence from the item to be tested by forensics.

At Superior Bag, our varied selection of evidence bag sizes means that law enforcement always has the best option for the situation. Not only is the Superior Evidence Bag™ easy to write on, but the durability of the plastic also makes it tamper-proof yet resealable, establishing a chain of custody that reduces further risk of tampering as evidence is tested and used in cases. 

Did You Know?

Did you know that when plastic sandwich bags came on the market, they were quickly used by law enforcement in crime scene investigations? It seemed like the perfect solution. However, the new-fangled bags were too good to be true, and police officers would inevitably put too many items into a single plastic sandwich bag, damaging the items and causing cross-contamination. The bags themselves would also get damaged in the process, leaving tears in the plastic with its contents no longer airtight. 

The Superior Difference

That’s why Superior Bags are made to resist tears. They are also printed for documentation by law enforcement departments, so each tamper-proof bag can be listed with information such as dates, locations, and officers examining the evidence, thereby creating a chain of custody that is simple to track. 

But are plastic bags always the best container for evidence? Anything involving fluids, such as sweat or blood, should never be placed in a plastic bag since it can damage any DNA traces. It’s important for law enforcement officials to maintain the integrity of the evidence by knowing what types of materials belong in either a paper or a plastic bag. 

Dry fibers, such as fabric or strands of hair, are safe to place in a plastic bag. However, items such as paint chips, glass, DNA samples, or anything moist should either be placed in a paper or metal containers so as not to risk damaging evidence. 

Choosing The Superior Evidence Bag™

As the bag of choice for law enforcement, Superior Bag offers evidence bags that tackle all investigative needs. The Superior Evidence Bag™ offers a large space to document in-depth evidence details, from agency name and item descriptors to an expansive table of chain of custody signoffs.  

Made of durable, clear plastic, The Superior Evidence Bag™ safeguards all contents from elements such as liquid and debris and allow law enforcement personnel to easily identify the bag’s components. Fastened with a patented, high-quality, tamper-evident seal, The Superior Evidence Bag™ will also help protect contents from contamination and tampering.
