Chapter 1: What are Tamper Proof Bags?
For securing crime scene evidence, tamper-evident bags are crucial. These bags are constructed from heavy-duty, leak-proof polyethylene, which is resistant to tears and punctures. They feature a robust adhesive seal to ensure the contents remain secure.
In modern eCommerce, courier bags play a vital role. Tamper-proof courier bags are particularly valuable for companies looking to streamline their shipping and storage processes, as they facilitate professional and secure packaging of goods. These bags are commonly used by courier and logistics firms for items such as electronics (e.g., mobile phones, USB drives), jewelry, and watches, which are semi-fragile.
Self-adhesive or heat-seal technologies enhance the efficiency of sealing, while the integrated pod jacket eliminates the need to attach documentation separately. This makes it a cost-effective solution for large orders of custom designs. Additionally, courier bags are ideal for branding, as they allow for the direct printing of marketing and advertising materials on the package to increase brand visibility.
The tamper-proof courier bags feature a hot-melt adhesive strip that ensures once the bag is sealed, it cannot be opened without damage. Made from co-extruded film, these bags are fully recyclable and resistant to oil, water, and rough handling. The transparent pod jacket on the reverse side of the bag provides a convenient spot for inserting waybills, addresses, and other important documents.
Chapter 2: What are evidence bags and how are they used?
Evidence bags are specialized containers designed for collecting and preserving evidence. They can be made from paper or plastic, depending on the type of evidence they are intended to hold. Given that evidence bags may contain various items, including sharp or pointed objects, they are constructed to be highly durable to prevent ripping or breaking.
These bags often feature blank sections on the front where important information can be recorded, such as the chain of custody, the relevant case details, and the location where the evidence was originally found.
While related pieces of evidence may be stored together in a single bag, it is common practice to use separate evidence bags for each significant item. For example, shell casings of the same caliber from a gun might be stored together in one bag if they are believed to be fired from the same weapon.
Each evidence bag typically becomes an individual exhibit in the case, assigned an exhibit number for court and jury review. However, highly sensitive or hazardous items may not be displayed openly as exhibits, due to safety or confidentiality concerns.
Crime Scene Evidence Bags
Evidence bags are critical for securing a crime scene. These bags must be tamper-proof to ensure the integrity of the evidence. Additionally, they are usually translucent, allowing for clear visibility of the contents without opening the bag.
Forensic Bags
Forensic evidence bags are specialized airtight containers featuring two separate chambers. These bags are versatile and can be used to store various types of evidence, such as fingerprints, cell phones, and shoes collected from a crime scene.
Chain of Custody Bags
Police and forensic organizations use chain of custody bags to gather evidence for laboratory analysis, maintain accurate records, and ensure that the evidence is handled only by authorized personnel.
Tamper-Proof Evidence Bags
Tamper-proof evidence bags are made to collect significant samples or evidence from an accident or crime scene. These bags are made of thick plastic materials that are tear- and puncture-resistant and are designed to be leak-proof. The adhesive seal is also quite strong.
When sending sensitive documents, it is important to use tamper-proof mailers to ensure that only the intended recipient can access the contents. Tamper-evident mailers come with tracking codes and are designed so that any attempt to reopen them leaves visible evidence. These mailers are ideal for securely transmitting private or confidential materials, providing high levels of protection throughout the mailing process.

Reasons for Using Tamper-Evident Bags (TEB)
Criminal investigation officers must use Tamper-Evident Bags (TEBs) supplied by their home office.
Each TEB is designed to:
Preserve evidence
Produce that evidence as exhibits in court
Items collected from a suspect that could be valuable for future investigations must be securely stored and protected using these bags.
How to Use a TEB
A Tamper-Evident Bag (TEB) is a clear, leak-proof plastic bag featuring a robust adhesive seal. New nitrile gloves should always be worn when handling evidence. Items collected for forensic testing or analysis should be managed in the following manner:
In a clean environment
On a clean surface
To avoid contaminating the bag, handle it carefully by inflating it slightly, inserting your hand or arm, and then turning it inside out. This method helps maintain the bag's cleanliness and integrity.
Whenever possible, arrange the item inside the bag so that it remains visible without needing to open it. For instance, if a piece of paper contains crucial evidence, place it in the bag in a way that makes it visible. Additionally, scanning the contents is still advisable for thorough documentation.
How to Seal a TEB
The TEB seal features an adhesive strip that bonds with an orange and white security strip upon sealing, along with a blue "peel off" strip. When the blue strip is removed, the adhesive underneath adheres to the orange, white, and green security strip. It is important to ensure that the contents of the bag do not come into contact with this adhesive. To properly seal the bag, follow these steps:
Place the TEB on a flat surface.
Hold one corner of the orange security strip using one hand.
Pull the corner of the touching blue security strip away with the other hand.
"Smooth down" the sticky strip to the orange, white, and green security strip as usual.
When to Use a TEB
Whenever possible, a Tamper-Evident Bag (TEB) should be used for any property collected during investigations. TEBs come in various sizes, including options up to 2.2 by 3 feet (0.675 × 0.9 m), and are suitable for almost all types of seizures, including large-scale ones. If sealing the bag’s opening is not feasible, an alternative seal can be used, and the item should be clearly marked. Sharp objects should be enclosed in a suitable container before being placed in the TEB. Clothing should be placed in a paper bag, sealed, and labeled as an exhibit. For moist or wet materials, use breathable TEBs if available; otherwise, these items can be placed in an open bag inside a TEB. For best practices, cash and items requiring forensic analysis should be double-bagged: first placed in one TEB, sealed, then placed in a second TEB, sealed again, and ensure that all relevant details on the TEB label are completed accurately.
Leading Manufacturers and Suppliers
Chapter 3: What are tamper-proof bags and envelopes with bubble wrap used for?
When customers order products, they expect their goods to arrive intact and untampered. Failure to meet these expectations can lead to customer loss and negative reviews about the company's quality control. To ensure products reach clients without damage or tampering, using tamper-proof packaging with bubble wrap is highly effective. This method is employed across various industries to safeguard shipments.
These tamper-proof bags are cost-effective and serve their purpose well. They are widely used in retail, finance, e-commerce, education, healthcare, and pharmaceutical sectors.
Applications for tamper-proof bags with bubble wrap include online retail, logistics, and courier services. They are ideal for transporting sensitive items such as private documents, bank statements, invoices, exam papers, business documents, marketing materials, and fragile, valuable goods.
These bags are lightweight yet strong, and they offer moisture resistance. They feature an adhesive strip that creates a permanent seal once the contents are secured inside. This packaging helps prevent tampering, providing clear evidence if the bag has been compromised.
Additionally, manufacturers of tamper-evident bags produce recyclable, dependable, and strong items. They come in various sizes and colors and are simple to use. Even better, one can alter it to suit custom professional needs. These bags allow for the imprinting of a brand, a company name, and other information.
Tamper-proof bags with bubble wrap effectively absorb shocks during the supply chain, protecting the contents from damage. They are commonly used for shipping delicate items to ensure they arrive in pristine condition.
Due to their benefits, tamper-evident envelopes are in high demand. In the digital and e-commerce era, these envelopes are crucial for safely delivering goods, important documents, confidential correspondence, and business reports.
Plain envelopes leave documents vulnerable to theft. High-quality tamper-proof envelopes help prevent unethical behavior by couriers and other intermediaries, ensuring secure delivery of sensitive materials.
Chapter 4: What are deposit bags
A deposit bag is a durable, reusable container designed for transporting checks and cash to the bank for deposit. Constructed from strong materials to resist tearing, these bags often feature locking mechanisms to secure the contents. Banks commonly provide these bags at no cost to commercial clients who handle large volumes of cash and checks, while private customers can usually obtain them upon request.
Deposit bags are typically compact and rectangular, often featuring a subtle design with a bank emblem. They are designed to fit neatly into a briefcase or similar carrying case. Locking deposit bags usually come with secure zippers and may include a tag slot for adding personal identification details such as names and contact information.
When transporting cash to the bank, deposit bags help ensure the security of the money, reducing the risks associated with handling cash directly.
These bags are particularly useful for night deposits, allowing customers to drop off payments after banking hours. Some banks provide specialized tamper-evident bags that reveal if tampering has occurred by the morning. While standard deposit bags can be used, sealed bags are often preferred to prevent contents from spilling during nighttime drops. If a deposit bag is mistakenly sent to the wrong financial institution, the bank will typically arrange for its return or contact the account holder. For after-hours deposits at closed branches, deposit bags offer significant practicality.
However, deposit bags do not offer theft protection. A determined thief might still find ways to access a locked bag and remove its contents. To enhance security, it is advisable to keep the bag concealed among other items and be vigilant for signs of potential theft. Employees handling large amounts of cash may also request a police escort when making night deposits for added safety.
Deposit bags can be purchased from suppliers who offer a range of products, including checkbooks and coin rolling supplies, as well as directly through banks. For those seeking bags with specific features, ordering from these suppliers might be more cost-effective than obtaining them through the bank.
Chapter 5: What are bank coin bags?
Businesses that manage and transport large volumes of currency often find bank coin bags to be both popular and practical. Given the weight and bulk of coins, handling them can be time-consuming and labor-intensive. An effective alternative to traditional options is canvas coin bags, which offer durability and convenience. Bank coin bags are particularly useful in environments like retail stores, bars, and restaurants. They come in various sizes, which makes them ideal for managing small amounts of cash. For instance, a stadium employee selling food or souvenirs can easily handle transactions with a coin pouch that is easy to maintain. These bags are also beneficial for businesses that need employees to carry cash for providing change.
The largest available size, measuring 14” H by 28” W, is made from 10oz natural, untreated cotton duck fabric. This material provides ample space for carrying and helps ensure the longevity of the bag, even with frequent use and some wear and tear.
Heavy Duty Clear Tamper-Evident Coin Security Deposit Bags
These coin deposit bags are crafted from a specialized, three-layer film designed to be thick and durable, ideal for securing loose change from laundromats, coin-operated vending machines, arcades, and similar establishments. They are well-suited for any business that relies on coin operations.

Each bag features a tamper-proof locking adhesive strip and is constructed from 0.002 inch (0.06 mm) extra-strength polyethylene, making it well-suited for use as a banker's money bag holder. The bags include a writable white area on the front, allowing for easy documentation with spaces for the register number, date, cashier's signature, currency total, coin total, check total, credit card total, total contents, comments, and additional signatures. These bags are ideal for professional applications, including diplomatic, private, financial banking, notarial, and similar uses.
Clear Deposit Bags
These tamper-evident deposit bags are designed to provide security when handling money. Constructed from a durable co-extruded film, they are tamper-evident, offer superior self-sealing capabilities, and are resistant to water and tears. Their transparent design allows for easy identification of contents, while clear, legible writing areas facilitate straightforward documentation. High-visibility federal-compliant barcodes ensure that handheld scanners can easily capture the data.
The tamper-evident seal ensures contents remain secure during transit. Each bag features detailed written instructions, a unique matching barcode, sequential numbering, and a peel-off receipt for efficient tracking. Additionally, a printed dotted line at the bottom of the bag indicates where it should be cut once received by the recipient.
These bags are ideal for various business-related purposes, including diplomatic, private, and financial transactions. Their bulk availability ensures that companies can maintain a steady supply over an extended period.

Chapter 7: What are zippered lock bags?
Zippered lock bags, sometimes called zipper bank deposit bags, are plastic bags with zipper-locked mouths manufactured of PE plastic. This design makes it easier for the bag to be airtight, which helps preserve the product well. Due to that, they are widely used in various industries, particularly for storing food, sanitary products like masks, and medical supplies.
Advantages of Zippered Lock Bags
Tough and long-lasting
Waterproof
Food lasts longer, doesn't mold or smell, and doesn't leak liquid
Safe
Zipper can be separated by hand
Comfortable to carry and easy to pack
Made without a lanyard and has a zipper lock
Common Models of Zip-Top Bags
Zippered flat-bottom bags
Zippered bags in silver
Bags with clear zippers
Bags with zippers and handles
Intricate zip-top bag
Zippered food bags
One common question among consumers is whether zip-top bags are suitable for food storage.
In fact, zip-top bags are often referred to as food-safe bags due to their excellent properties for preserving food and their convenience for use and transport.
These bags offer impressive heat resistance, ranging from -76°F to 230°F (-60°C to 110°C), making them suitable for storing both frozen and hot foods. Their ability to maintain safety through sterilization ensures that the food remains safe for consumption. While zip-top bags are frequently used for food storage because of these safety features, it is important to choose the right type of bag based on the specific food being stored.
Chapter 8: What is the difference between tamper-proof and tamper-evident bags and seals?
Different tamper-evident bags and seals are described using various names, which often reflect the level of security they provide. However, these terms can sometimes be misleading. Therefore, it’s important to understand the terminology used in the security seal industry.
Take the term "tamper-proof," for example. While "proof" is commonly associated with terms like waterproof or soundproof, implying complete imperviousness, in the security seal industry, it often refers to tamper-resistant systems. This can be confusing because "proof" also means "evidence" in other contexts. Although many security bags and seals provide a substantial deterrent against tampering, no security measure is completely impervious without showing evidence of tampering. Robust seals, such as metal-indicative and cable seals, require specialized tools to breach and have medium-to-strong break resistance.
Another commonly used term is "tamper-obvious." Tamper-obvious bags and seals are designed to visibly indicate any tampering attempts. These seals vary widely in their resistance to tampering, from low to strong. They are intended to discourage theft through visible signs of tampering, supported by additional security measures like barcodes, sequential numbering, color coding, employee screening, and thorough record-keeping practices.
Safe custody tamper-evident bags, which feature several sabotage-exposing processes, are more examples of tamper-evident devices. The closure includes a liner, membrane, adhesive, perforation lines, and a security edge print that will make any manipulation (such as cutting, freezing, heating, or using solvents) clear. Additionally, adhesive void labels, padlocks, and a selection of biodegradable polyethylene seals are tamper-evident. These can be hacked away with a sharp knife or strong hands, although doing so will make any disruption noticeable.
Metals and tough polymers are the primary components of high-security seals. The phrase "high security" refers to locking mechanisms that have undergone rigorous testing to evaluate their sturdiness and strength and have received certification to an international standard for use in bringing in and bringing out goods through customs. The ISO (International Organization for Standardization) has provided this compliance standard, delivered by the standards needed by the ISO/IEC Directives, Part 2. "Uniform methods for the classification, acceptance, and of mechanical freight container seals" are guaranteed by the ISO 17712 rating. It gives information about mechanical seals that can be used to secure freight containers in global trade from a single source. This classification includes cable steels and bolt seals; instruments like cable cutters and angle grinders are required to remove them after application. The latter is also a great indicator of a breach because it has defective cabling that frays when cut.
