Engineering the Future of Drug Delivery: A Multi-Layer Adhesive Breakthrough

Engineering the Future of Drug Delivery: A Multi-Layer Adhesive Breakthrough

How advanced adhesive technology is transforming pharmaceutical delivery systems

Introduction

The pharmaceutical industry is undergoing a quiet revolution in drug delivery. While oral medications and injections remain common, transdermal delivery systems—which administer medication through the skin—are emerging as game-changers for patient compliance, consistent dosing, and reduced side effects.

At the heart of this innovation lies an often-overlooked component: the adhesive system that makes it all possible.

At The Tape Lab, we recently partnered with a pharmaceutical developer to engineer a multi-layer adhesive system that fundamentally reimagines how medications interact with the body. This breakthrough demonstrates how sophisticated adhesive engineering is not just supporting medical innovation—it’s actively driving it.

The Challenge: Beyond Simple Adhesion

When our pharmaceutical partner approached us, they outlined multiple complex requirements that far exceeded conventional adhesive functionality:

  1. Directional Drug Delivery: The system needed to ensure medication moved downward into the skin, not laterally or outward 
  2. Temperature-Activated Release: The medication needed to be released only when in contact with body temperature (98.6°F) 
  3. Moisture Balance: The adhesive needed to maintain an appropriate moisture environment for effective drug absorption 
  4. Extended Wear Performance: The system needed to remain adhered for the full therapeutic duration while remaining waterproof 
  5. Biocompatibility: All materials needed to meet stringent biocompatibility standards for prolonged skin contact 

Creating a solution that addressed all these requirements simultaneously required rethinking the fundamental structure of transdermal delivery systems.

The Solution: A Purpose-Built Layered System

Rather than approaching this as a simple adhesive application, we engineered a comprehensive multi-layer system where each component serves a specific therapeutic purpose:

Layer 1: Waterproof Barrier

The outermost layer utilizes our TTL 6840 long-term wear tape technology, a specialized breathable but waterproof barrier that protects the entire system from external moisture while allowing natural skin transpiration. This material maintains its protective properties during showering, exercise, and daily activities, ensuring consistent drug delivery regardless of conditions.

Layer 2: Drug Reservoir

The middle layer features a custom-engineered absorbent matrix designed to hold the pharmaceutical agent in suspension until activation. This layer was specifically calibrated to work with our partner’s proprietary medication formulation, ensuring compatibility and stability throughout the product’s shelf life.

Layer 3: Hydrophilic Directional Interface

The innovation that truly transformed this system was the development of a specialized hydrophilic material that creates a one-way pressure differential. When activated by body heat at precisely 98.6°F, this layer undergoes a controlled phase change that generates downward pressure, directing the medication into the skin rather than allowing lateral diffusion.

This directional pressure ensures maximum therapeutic efficiency by focusing medication delivery exactly where it’s needed—into the underlying tissue rather than spreading across the skin surface.

Technical Execution: Material Science Meets Pharma Necessity

Developing this solution required pushing the boundaries of adhesive material science:

Temperature-Sensitive Polymer Development

The temperature-activation mechanism was achieved through a specialized polymer blend that undergoes a precisely calibrated phase change at body temperature. This required extensive testing across different environmental conditions to ensure that premature activation wouldn’t occur during storage or transport, while guaranteeing consistent activation when applied to the skin.

Hydrophilic Engineering

The directional flow characteristic was achieved by creating a gradient of hydrophilic properties within the adhesive matrix itself. This required precise control of material porosity and surface chemistry to establish the necessary pressure differential that drives medication downward.

Biocompatibility Optimization

Throughout development, each material component underwent rigorous biocompatibility testing according to ISO 10993 standards. This involved iterative reformulation to eliminate potential irritants while maintaining the critical functional properties of the system.

Results: Performance Beyond Expectations

The final system delivered exceptional performance across all requirements:

  • Directional Efficiency: Testing showed a 68% improvement in drug penetration compared to conventional transdermal systems
  • Consistent Release Profile: Medication release maintained ±4% consistency throughout the wear period
  • Waterproof Performance: The system maintained full functionality through water exposure testing equivalent to daily showering
  • Extended Wear Time: Reliable adhesion for the full 7-day therapeutic duration with minimal degradation
  • Patient Comfort: Reduced skin irritation by 72% compared to previous transdermal solutions

Implications for the Future of Drug Delivery

This technological breakthrough has implications extending far beyond this single application:

Expanding the Range of Transdermal Medications

Many medications previously unsuitable for transdermal delivery due to diffusion limitations can now be reconsidered with this directional delivery technology. This has the potential to transform treatment regimens for conditions ranging from chronic pain management to hormone replacement therapy.

Personalized Medicine Applications

The precision control offered by this system opens possibilities for more personalized medication delivery, with potential for custom formulations tailored to individual patient needs and metabolism rates.

Combination Therapy Possibilities

The multi-layer structure creates opportunities for delivering multiple therapeutic agents with different release profiles from a single application, potentially simplifying complex treatment regimens.

From Innovation to Implementation

The journey from concept to commercial application required close collaboration between our adhesive engineering team and our pharmaceutical partner’s medical specialists. This interdisciplinary approach was crucial in bridging the gap between adhesive technology and therapeutic requirements.

Key elements of this successful partnership included:

  • Iterative Prototyping: More than 14 prototype iterations were developed and tested
  • Real-World Simulation Testing: Performance evaluation under various environmental conditions and activity levels
  • Regulatory Pathway Planning: Proactive design considerations to support FDA approval processes

Conclusion: Adhesive Innovation as Medical Advancement

This case demonstrates how advanced adhesive technology is not merely a component of medical innovation but often the enabling factor that makes breakthrough treatments possible. By approaching adhesive development as a fundamental therapeutic challenge rather than simply a means of attachment, we’ve helped create a system that significantly advances the possibilities for transdermal drug delivery.

For medical device engineers and pharmaceutical developers, this underscores the importance of considering adhesive technology as an integral part of the therapeutic solution rather than an afterthought.

The future of drug delivery will increasingly rely on sophisticated adhesive systems that do far more than simply stick—they will actively participate in the therapeutic process, improving efficacy, patient compliance, and treatment outcomes.

Patient comfort and medical stick-to-skin products

Various sizes of adhesive bandages on blue background.

Medical stick-to-skin products represent a significant opportunity for manufacturers because of how frequently they are used in today’s healthcare industry. Patient monitors, wound dressings, sensors, surgical tape, diagnostic tape and other wearable adhesive products have all become critical components of modern approaches to patient care. But in order for these products to be effective, manufacturers need to limit patient discomfort as much as possible, particularly for outpatient applications. Not only that, but the complexity of these items make them more akin to consumer electronics goods than other tape products. So, there’s a lot you need to think about when creating a product that will be successful in the market. Here’s a look at some of the top issues manufacturers need to consider when developing comfortable and effective medical stick-to-skin products.

The pillars of medical stick-to-skin products

When developing medical stick-to-skin products, there are three main concepts every manufacturer needs to keep in mind above all others:

Autonomy – In an in-patient setting, medical professionals can assist with applying and removing stick-to-skin medical tape. But for outpatient care, patients need to be able to manipulate devices themselves, sometimes with one hand. So, product developers should use adhesives that won’t be too painful or difficult to remove while also considering how the liner system and overall design of the product impacts a patient’s autonomy.

Discretion – There is some expectation in an in-patient setting that medical devices may be somewhat intrusive or would otherwise be considered unsightly in other circumstances. In other words, medical devices aren’t expected to be especially discreet. But for outpatient applications, it’s another story. Product developers need to design products that can be worn discreetly while still achieving intended performance goals.

Mobility – Regardless of where the patient is, stick-to-skin medical devices need to be designed in such a way that patients can practice normal movements without damaging the device or hindering its effectiveness. Product developers need to consider activities like showering, exercising, sleeping and other natural, daily movements when designing devices and selecting materials.

By developing products with these principles in mind, medical device manufacturers can create comfortable products that work for real-world applications and achieve the desired medical outcome.

Other considerations for medical tape products

Moisture management

Moisture management is important for any stick-to-skin product, but particularly for medical devices. Where wounds and other medical conditions create high moisture environments, keeping the skin as dry as possible can be key to the healing process, protecting skin from becoming damaged and having a direct impact on patient comfort. Therefore, moisture management should be a main consideration for any medical product developer.

Sweat, blood, natural oils, medicated ointments, lotions and other substances create a challenge for medical tape products because they can impact adhesive effectiveness. The key to overcoming that challenge is to select the right adhesive materials for your particular application. In short, there are two ways that adhesives manage moisture: vapor transmission and fluid absorption. Each method has distinct advantages and disadvantages, so selecting the appropriate approach will depend on the specific function of your device. An experienced engineering professional can help you select the right medical adhesives materials for each layer of your product to achieve the desired outcome.

Skin as a surface

Part of what makes medical stick-to-skin products so challenging to develop is that skin is an incredibly dynamic surface. Cells are constantly regenerating, the body exudes fluids, the age of skin impacts its properties and the entire surface is elastic. Accounting for all of these factors is no easy feat. So, partnering with a converter that has experience in the medical industry can help you go from concept to commercial production by offering guidance and support throughout the product development cycle.

Optical clarity for site checks

If treatment providers need to be able to visually inspect the application site without removing the stick-to-skin product, you will need to choose optically clear materials, including your adhesives. This type of product need should be identified early in the development cycle so you can streamline materials selection and bring your product to market faster.

Whether you’re developing a new type of bandage or a truly revolutionary product that will forever change the practice of medical care, patient comfort always needs to be a top consideration. That starts with selecting the right materials and making the right design decisions. By staying focused on both patient and product needs, you can develop great medical products that help improve the lives and health outcomes of your users.
