Importance of Tamper-Proof Evidence Bags in Forensic Investigations

Tamper proof bags are designed to ensure the safety of sensitive materials stored in them. These bags play an indispensable role across industries, such as pharmaceutical and law enforcement, in ensuring the integrity of the contents from production to delivery. Are you intrigued to know how these bags work? Or applications of these bags? Or do you want some guidance in choosing them for your applications? If answers to all these questions or any of these sound yes, then this post is for you. It discusses these tamper-evident bags in detail and offers you the possibility to consider them for your storage and transportation purposes.

Tamper-Evident Bags and Their Features

It is quite obvious to ask how tamper-evident bags differ from regular plastic packaging bags. The following pointers on their features will help you understand them better.

  • These evidence bags are made from strong, tear-resistant materials that help protect the contents inside.
  • Tamper-evident seals are one of the most important characteristics of tamper proof evidence bags. These seals are intended to indicate whether the bag is in the same state or has been opened or tampered with.
  • There are numerous features like adhesive strips, serial numbers, or distinctive markings that add security to these bags. These features also help users understand if the contents have been tampered with or changed or if someone has tried opening the bag.
  • Another important feature of these tamper-evident transport bags is their transparency which makes it simple to view the stuff stored inside the bag.
  • These bags are also sometimes used in the pharmaceutical packaging industry as they enhance the safety of pharmaceutical products and provide a barrier against tampering or contamination.

Why Are Tamper Proof Bags in Demand across Forensic and Pharmaceutical Industries

Tamper proof bags are in demand across these industries due to the following reasons.


  • Preservation of Evidence Integrity: Preserving the integrity of the forensic evidence is the major goal of tamper-proof evidence bags. Investigators reduce the possibility of evidence tampering or degradation by sealing evidence in tamper-proof bags as soon as it is collected. This keeps the evidence immaculate and trustworthy for analysis.
  • Chain of Custody Management: Establishing a clear and unbroken chain of custody is essential for establishing the authenticity and reliability of evidence in court. Tamper-proof evidence bags are equipped with features such as tamper-evident seals, serial numbers, or barcodes that serve as documented records. This meticulous tracking helps prevent unauthorized access or tampering, thereby bolstering the credibility of the evidence.
  • Legal Admissibility: In legal proceedings, the admissibility of evidence is based on its integrity and the reliability of the chain of custody. Tamper-proof evidence bags provide tangible evidence of proper handling and storage, which strengthens the evidentiary value of the collected items. Courts are more likely to admit evidence that has been securely sealed and documented in tamper-proof bags, enhancing the prospects of a successful prosecution or defense.
  • Protection against Contamination: Forensic evidence is susceptible to contamination or human abuse. Tamper-proof evidence bags create a barrier that shields the contents from external pollutants, biological materials, or hazardous substances. By minimizing the risk of contamination, these bags help preserve the integrity of the evidence and facilitate accurate analysis in the laboratory.
  • Compliance with Professional Standards: Forensic science and law enforcement agencies adhere to strict protocols and standards governing evidence-handling procedures. The use of tamper-proof evidence bags is often mandated by these standards to ensure consistency, reliability, and accountability throughout the investigative process.

Pharmaceutical Industry

  • Drug Safety: Tamper-proof packaging is widely used for medical packaging because medications should not be altered, contaminated, or tampered with.
  • Brand Protection: Tamper-proof packaging helps pharmaceutical companies prevent counterfeit medications from flooding the market shelves.
  • Regulatory Compliance: The pharmaceutical packaging industry is one of the most highly regulated due to the safety concerns involved. Regulatory bodies in the US mandate stringent packaging requirements for pharmaceutical manufacturing companies to avoid potential product recalls and legal hassles.
  • Improved Customer Confidence: Tamper proof bags such as security pouches are used in the pharmaceutical industries to store syringes, prescription medications, clinical trial samples, over-the-counter (OTC) drugs, controlled substances, high-value pharmaceuticals, vaccines, medical devices, diagnostic kits, and so on. By looking at these bags, customers are likely to feel confident about the safety of the medications.
  • Efficient Logistics and Distribution: Tamper evident transport bags can withstand the rigours of transportation, which helps reduce the risk of damage to high-value sensitive medicines.

Keep in Mind While Buying Tamper Evident Transport Bags

If you are planning to buy tamper proof bags, you must consider the factors below to ensure their effectiveness.

  • Tamper-Evident characteristics: Check if the bags have characteristics to state whether they have been opened or tampered with. These bags can have features like security seals, sticky closures, or locking mechanisms which makes it easier to reveal their exact state.
  • Material Quality: Choose bags composed of strong materials that do not tear, puncture, or get tampered with. Security pouches made from high-density polyethylene (HDPE), polypropylene, or multi-layered films can resist harsh handling and climatic conditions.
  • Security Seals: Consider the potency of the seals used to secure the bags. Adhesive seals, security tapes, numbered seals, and barcoded seals are examples of tamper-evident seals.
  • Chain of Custody Documentation: A few tamper proof bags have built-in features, like written surfaces where details about the evidence, like dates, times, signatures, and identification numbers, can be recorded. These characteristics aid in keeping an accurate and traceable record of how the evidence was handled.
  • Size and Capacity: If you select bags in appropriate sizes and capacities, it is easier to accommodate items that are going to be stored or transported. Additionally, you must consider the dimensions and volume of the evidence to ensure a proper fit within the bags so that you don’t end up overcrowding or excessive empty space.
  • Compatibility with Types of Evidence: Storage and transportation needs for various types of evidence and medicines may differ. You must select bags that are appropriate for the kinds of evidence you frequently deal with in your field, such as documents, biological samples, clothing, medicines, weapons, and other objects.
  • Compliance with Standards and Regulations: Ensure that the tamper-proof bags meet relevant industry standards, guidelines, and regulatory requirements for evidence or drug handling and storage.
  • Supplier Reputation and Support: To receive quality bags, it is vital that you select a manufacturer or supplier who has a solid track record of manufacturing and supplying tamper-proof bags of the highest potential and offers first-rate customer service. Think about things like responsiveness, dependability, warranty choices, and the availability of customization or technical support.
