Tamper-Evident Packaging That Protects Prescription Medicine and OTC Products

Why Tamper-Evident Packaging Matters for Regulated Products

Regulated industries such as pharmaceutical, over-the-counter (OTC), and wellness sectors have a responsibility to keep products secure until they reach consumers. In addition to protecting end-users, manufacturers must demonstrate compliance with regulatory requirements and safeguard brand integrity.

The U.S. Food & Drug Administration (FDA), under 21 CFR § 211.132, defines tamper-evident packaging as packaging that provides visible evidence if a product has been opened or altered. Tamper-evident packaging does not necessarily prevent access, but it clearly indicates when access has occurred.

This differs from tamper-resistant packaging, which is designed to make opening more difficult but may not provide visible proof of interference.

PLPS focuses on tamper-evident solutions delivered through pressure-sensitive labels and shrink sleeve formats, providing regulated brands with scalable, compliant options.

For a deeper overview of tamper-evident label formats and applications, see our Guide to Tamper-Evident Labels.

How Tamper-Evident Labels and Seals Work

Pressure-sensitive labels and seals incorporate elements that serve as warning signs of tampering. Many companies choose pressure-sensitive labels because they can be applied quickly from a roll and provide options for serialization and traceability. The three most commonly used types of pressure-sensitive tamper-evident labels are:

• Destructible: In the simplest sense, labels can be applied as a seal on a cap or lid, keeping the container sealed and being destroyed once it is opened. This provides the user with an easily visible sign that it has been opened and potentially tampered with before purchase.
• Void: Similarly, labels can be printed with special adhesive patterns that can leave behind the word “VOID” or related messaging. This serves to alert the consumer that a seal that had been applied at the production facility has been removed.
• Perforated: Shrink sleeves featuring perforated tear-away tabs for removal can be printed to make them highly visible to consumers. This makes them easy enough for a consumer to open but still provides an obvious sign that the product has already been accessed.
• Residue: In the same way that “VOID” labels function, these leave behind a visible pattern when removed. This notifies whoever is handling the packaging that it has been opened already and possibly interfered with in some way.

Premium Label & Packaging Solutions offers a wide range of options to make pressure-sensitive labels an effective deterrent to tampering. Our solutions ensure our clients gain the speed, traceability, and compatibility needed to support their product lines.

Shrink Bands and Shrink Sleeves for Secure Closures

Shrink bands and shrink sleeves can provide highly visible tamper-evident features when applied around caps or closures. These components must be torn or removed before opening, making interference immediately apparent.

Shrink sleeves are commonly used for:

• Bottles
• Vials
• Jars

Shrink neck bands are often preferred when brands require full-cap coverage or additional visual assurance at the point of purchase.

PLPS manufactures shrink sleeve solutions engineered for regulated markets, including options compatible with sustainability goals.

Selecting the right shrink sleeve solution depends on supplier capabilities, material expertise, and production scalability. Brands should carefully evaluate these factors when choosing the right shrink sleeve supplier for their brand.

Tamper-Evident vs. Tamper-Resistant Packaging

While tamper-resistant packaging is designed to make access more difficult, tamper-evident packaging is intended to show clear, visible signs if access has occurred.

Although they may sound similar, there is a clear difference between tamper-resistant and tamper-evident packaging. The latter is designed primarily to make opening the packaging as difficult as possible to prevent tampering before the product reaches consumers. However, it may not provide evidence that it has been breached the way tamper-evident packaging does.

Therefore, many brands prioritize tamper-evident labeling and packaging because although it may not prevent tampering, it provides a clear warning to consumers that the product may have been compromised and should not be used.

Compliance and Market Expectations

Packaging plays an important role in helping manufacturers in highly regulated industries meet their compliance objectives. In many cases, regulations call for tamper-evident packaging for clinical trials as well as for consumer-ready products.

Visible tamper evidence is often expected to support patient safety, documentation standards, and audit readiness in regulated environments.

PLPS helps our clients stay in compliance with the regulations that are most important to their businesses, with tamper-evident packaging and labeling options as well as labels that support documentation requirements. We understand the importance of consistency in operating procedures as well as support for audit requirements.

Sustainable and Earth+ Tamper-Evident Options

As sustainability becomes a bigger concern for manufacturers and consumers, it’s important for healthcare, pharmaceutical, and wellness product packaging to be sustainable without sacrificing safety. Fortunately, PLPS offers a solution in the form of our Earth+ lineup of sustainable and recyclable packaging.

PLPS Earth+ solutions for tamper-evident packaging include recyclable shrink sleeves as well as downgauged label facestock that use less material. At the same time, these options also provide the same level of protection as standard tamper-evident packaging.

Choosing the Right Tamper-Evident Format

No matter what form products take, there is a way for its packaging to protect consumers by displaying evidence of tampering. Shrink bands and tamper-evident labels can be used on their own or in combination to ensure pharmaceutical and OTC compliance as well as meet clinical trial labeling requirements.

PLPS has the expertise and range of options to help manufacturers and packagers choose the options that make the most sense considering their line speed, regulatory needs, and material requirements.
