Meet the Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box: First Thoughts
As an equipment specialist with over a decade of field experience, I’ve learned that the devil is often in the details, especially when it comes to maintaining the integrity of evidence. This led me to investigate the Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box, a product designed for a critical role in chain-of-custody procedures. My search for a reliable sealing solution was driven by a need for tamper-evident methods that were both practical and cost-effective for routine use. I considered generic adhesive tapes, but their lack of specific evidence-marking features and potential for easy removal made them unsuitable. The initial impression of these Sirchie strips is one of straightforward functionality; the materials feel robust enough for their intended purpose. This pack promises a simple yet effective way to secure evidence, and my first reaction was one of cautious optimism, hoping it would live up to its specialized billing.
Real-World Testing: Putting Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box to the Test
First Use Experience
My initial testing of these integrity strips occurred within the controlled environment of a workshop, simulating the initial bagging and tagging of evidence items. I applied them to various surfaces, including plastic evidence bags, cardboard boxes, and even sealed paper envelopes, to gauge their adhesion and tamper-evident properties. The strips performed adequately in these controlled conditions, adhering well to standard materials.
During this first use, I noted that the adhesive had a good initial tack, allowing for repositioning if needed before firm pressure was applied. There were no immediate issues with the strips tearing prematurely or the ink smudging under light handling. The prominent red color with black “evidence” text immediately signals its purpose, which is a key functional aspect.
Extended Use & Reliability
After several weeks of intermittent use in various professional settings, these Sirchmark strips have held up reasonably well. I’ve used them to seal evidence bags containing everything from small tools to larger documents, and they’ve consistently maintained their adhesion. The material has shown no signs of degradation, such as becoming brittle or losing its color, even when exposed to moderate temperature fluctuations common in field storage.
Cleaning and maintenance are non-existent, as these are single-use security strips. Their disposable nature simplifies workflow significantly, eliminating the need for complex upkeep. When compared to generic sealing tapes I’ve used in the past, these strips offer a much clearer indicator of tampering, a critical advantage in evidence handling.
Breaking Down the Features of Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box
Specifications
The Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box comes as a 100-pack bulk offering. Each strip measures 1-3/8 inches in width by 7 inches in length, providing a substantial surface area for sealing various containers. The material appears to be a durable plastic film, designed to show clear signs of tampering if attempts are made to remove or reseal it.
The bright red color of the strip, coupled with the bold black print that reads “evidence,” is a crucial specification. This high-visibility design immediately communicates the strip’s purpose and the sensitive nature of the item it secures. The generous length ensures it can be applied across the opening of most standard evidence bags or containers, offering a secure closure.
Performance & Functionality
The primary function of these integrity strips is to provide a tamper-evident seal, and they perform this role effectively. When applied correctly, any attempt to lift or peel the strip results in it tearing or leaving behind a clear residue, indicating that the seal has been compromised. This makes them a reliable tool for maintaining the chain of custody.
The strength of these strips lies in their visual deterrence and the clear indication of tampering. While they may not be impenetrable, they significantly raise the bar for unauthorized access. They meet expectations for their intended purpose, offering a straightforward solution for evidence security without complex mechanisms.
Design & Ergonomics
The design of these evidence integrity strips is intentionally simple and functional. The 1-3/8 inch by 7 inch dimensions are practical for sealing standard evidence bags and containers. Their matte finish on the printable surface (though not explicitly used here for writing) suggests a potential for additional annotation if needed.
The material itself feels sturdy, not flimsy like some standard packaging tapes. This perceived sturdiness contributes to the feeling of security when applying them. The pre-printed “evidence” text is clear and unambiguous, which is excellent for quick identification and communication.
Durability & Maintenance
As single-use items, these Sirchmark strips are designed for immediate application and are not intended for long-term durability beyond their role as a temporary security seal. Their expected lifespan is tied to the duration the evidence remains in their custody, during which they should maintain their integrity. They do not require any maintenance; once applied, their function is complete until removed.
There are no apparent failure points that would cause them to malfunction under normal application. However, extreme temperatures or harsh chemical exposure, while not typical for evidence sealing, might affect adhesive performance over extended periods, though this is speculative.
Accessories and Customization Options
The Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box are sold as a 100-pack bulk item, so the primary “accessory” is the sheer quantity provided. No other accessories are included or necessary for their primary function. The strips are pre-printed with “evidence” and do not offer inherent customization options beyond their application.
The design does not easily lend itself to writing on with standard pens without smudging unless a permanent marker is used carefully. However, their core purpose is the visual tamper-evident feature rather than extensive annotation space.
Pros and Cons of Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box

- High Visibility: The bright red color and bold “evidence” text ensure immediate recognition of purpose.
- Generous Size: The 1-3/8 inch X 7 inch dimensions offer ample coverage for most evidence containers.
- Cost-Effective Bulk Pack: A 100-pack bulk option provides good value for frequent use.
- Simple Application: Easy to apply with a strong initial adhesive bond.
Cons
- Limited Writeability: While designed for sealing, writing directly on the strip can be challenging without smudging.
- Not for Extreme Conditions: May not be suitable for long-term exposure to harsh environmental factors like extreme heat or solvents.
- Single-Use Only: As a security measure, they are designed for one application and cannot be reused.
Who Should Buy Sirchie – Sirchmark Evidence Integrity Strips Red W/ Black Evidence 1-3/8inch X 7inch 100/box?
These integrity strips are ideal for law enforcement agencies, forensic investigators, and any professionals who handle and secure evidence that requires a clear chain of custody. They are also well-suited for laboratories processing sensitive samples or any situation where proving the integrity of a sealed package is paramount. Individuals or organizations requiring a visual deterrent and clear indication of tampering will find this product highly beneficial.
Those who need to label evidence extensively directly on the seal might want to consider using separate labels or markers alongside these strips. Anyone requiring absolutely impermeable seals against extreme environmental conditions might need to explore more specialized, and likely more expensive, security solutions. Essential complementary items would include standard evidence bags, collection kits, and permanent markers for annotating the evidence bag itself, not necessarily the strip.
