Innovations in packaging protect temperature-sensitive drugs.

Innovations in temperature-controlled packaging center on sustainability, performance, and cost.

Sustainability innovations

To improve sustainability, OptumRx, a pharmacy care services provider, has transitioned from rarely recycled foam packaging to recyclable packaging made from renewable cotton-based Kodiakotton from Kodiakooler, which was recently acquired by Airlite Plastics. The Kodiakotton insulating material is biodegradable, compostable, reusable, and recyclable. OptumRx projects the new packaging will save millions of gallons of water, pounds of carbon dioxide, and kilowatt-hours of energy (1). “OptumRX has had great success with our sustainable products,” reports Corbin. “Part of the initiative is ongoing education for their consumers on the benefits of recyclable materials,” he adds. 

In addition to Kodiakotton liners, Kodiakooler offers the patented Kwikpack system. This is a bundled kit of two Kodiakotton liners with an easy-to-remove, recyclable band. The liner bundle cuts insertion time and results in a packout-ready shipper in less than six seconds (2). 

Fiber-based options, which can be recycled in the corrugated or waste-paper streams, also are popular. To address this market, Thermo Fisher Scientific has developed the Invitrogen Paper Cooler. The 100% paper alternative to EPS foam coolers meets thermal requirements for overnight shipments (3). Another paper-based product, ClimaCell insulation from TemperPack, is designed to replace EPS insulation and reduce packaging waste. In addition to being recyclable in the corrugated stream, the ClimaCell material protects temperature-sensitive shipments for up to 80 hours. The material also is moisture-resistant and can be customized with printed graphics/messages (4). 

Another player in the insulation market, va-Q-tec, has opened a US headquarters and production facility in Langhorne, PA, to manufacture its small boxes and containers. The location also serves as a rental and repair station. The company, which is headquartered in Germany, specializes in vacuum insulation panels and phase-change materials that offer five-day temperature protection without the need for external energy sources. A rental service business offers a fleet of cold-chain containers and boxes (5).

Reuse is possible with the AcuTemp Plus Series of shippers from CSafe Global through its Repaq program. Proprietary, high-performance ThermoCor vacuum-insulated panels control payload temperatures. Simple to deploy, the shippers are available in multiple sizes and temperature profiles with integrated track-and-trace options (6). 

Although reusable packaging has gained ground, one-way shippers remain a viable choice and continue to evolve. AeroSafe Global, a supplier of reusable shippers, has added a disposable option to its portfolio. The A20 insulated shipper is designed to serve shipments needing protection for 24 to 48 hours. It is fully prequalified to ISTA 7D summer and winter profiles. Minimal components simplify packouts (7).

 

Gore Sta-Pure flexible freeze containers from Gore PharmBIO Products are designed to protect high-value bulk drug substances from container breakage or leakage during frozen handling. “Traditional single-use bags are constructed from materials that typically become brittle when exposed to temperatures below -40 °C, which can lead to cracks or leaks in the bags,” explains Cintavy. The proprietary high-strength fluoropolymer material used for the Sta-Pure flexible freeze containers is durable after freezing at -86 °C (-123 °F) and offers the convenience and scalability of a single-use system that efficiently uses freezer space. In addition to durability, the container’s chemically inert, biocompatible, high-purity fluoropolymer composite film has a low extractables profile (8).

Gore Sta-Pure flexible freeze containers come in sizes from 50 mL to 12 L with tubing and connector options to meet different pharmaceutical and bioprocess applications. A hard-shell carrier is available for easier handling. If carbon dioxide or oxygen permeation is a concern, an optional, vacuum-sealable, secondary barrier wrap minimizes ingress (9).

Introductions from Pelican BioThermal include a new version of its ProEnvision web-based asset management track-and-trace software, which allows integration of its CoolPall Flex bulk shipper into the Internet of Things. The CoolPall Flex shipper serves refrigerated, frozen, and room temperature ranges. A high level of flexibility allows the system to address different time, weight, and payload requirements. 

For cryogenic products, SAVSU Technologies has expanded its portfolio of dry vapor shippers, which maintain biologic payloads at -196 °C during storage and transport. Positioned between the DV4 and the DV10 shippers, the DV7 unit offers seven days of thermal autonomy and a more compact form factor with a payload capacity similar to the DV10 shipper. With its smaller size, the DV7 shipper is easier to handle and store and less expensive to ship (10). 

Cryoport Express Advanced Therapy Shippers from Cryoport have been developed to meet demand from biopharma customers and in anticipation of more stringent government regulations. The shippers are dedicated to human use and certified as such. Validated to ISTA 3A and 7E Transportation Standards, a new vapor plug design further doubles the holding time if shippers are mis-orientated during transit. The shippers also provide complete traceability of use history and assurance that each dewar is requalified for each trip for physical suitability, cleanliness, liquid nitrogen capacity, and shipment hold times. Validated cleaning processes reduce the risk of cross-contamination during use, delivery, and distribution (11). 

Sustainability continues to be a major driving force with suppliers and users of temperature-controlled packaging. As a result, work continues on developing designs that meet performance requirements that will be more renewable, recyclable, reusable, and/or compostable. Kodiakooler, for example, is working on biodegradable EPS foam. “We are constantly looking for ways to reduce the carbon footprint of temperature-controlled packaging materials,” says Corbin.
