Introducing the first ever thermal insulated envelope mailer with Integrated PCM refrigerants for shipping temperature-sensitive parcels

Pre-qualified mailer provides temperature stability for last-mile pharmaceutical delivery without needing a cooler and separate gel packs

thermal insulated mailers

The increasing demand for temperature-controlled packaging necessitates a lower-cost solution that is cost-effective and better for the environment.

The first-of-its-kind thermal insulated envelope mailer integrates PCM refrigerants into its construction, allowing specialty pharma and mail order drug organizations to send individual doses of medications at a stable room temperature with an envelope form factor. The solution removes the need for EPS coolers, a corrugated box, and separate refrigerants by integrating a proprietary phase change material (PCM) into the lining of the mailers and envelope:

  • Reduces shipping costs and minimizes the space required for CRT shipments
  • Reduces pack-out error by simplifying the packing process since there is only one fully cohesive component
  • Decreases packaging waste as no cooler or corrugate box is required
  • Envelopes are vacuum sealed and shipped in compressed bundles, which allows companies to stock inventory with ease until ready to use

Refrigerant Built into The Envelope

The thermal insulated mailers contains a Phase Change Material (PCM) selected for the specific temperature it maintains when transitioning between its solid and liquid states. 

In this case, the PCM will change from solid to liquid and protect from extreme heat, while the additional PCM will change from liquid to solid and protect from extreme cold.

Integrated PCM with Durable Envelope Construction

The insulated shipping envelopes uses layers of PCM enclosed and vacuum sealed within an open-cell polyurethane matrix insulated pouch to protect the product. The PCM is arranged in a mat format allowing the mailer to be flexible even in its solid state, making it ideal for parcel delivery at the lowest possible cost.

Qualified To the ISTA 7E Standard for URAC Requirements

Controlled room temperature (CRT) regulations and requirements are traditionally defined as 20–25°C, with allowable excursions of 15–30°C, as long as their mean kinetic temperature remains in the specified range. 

Recent URAC requirements have a potential CRT range of 2-25°C if the drug stability supports it per USP 659.

TempAid CRT Thermal Insulated Shipping PCM Envelope and Mailers are tested against the ISTA 7E Summer, Winter, Fall/Spring, and intermediate profiles using lane data gathered from real-world conditions and tested with several different product payload boxes and instrumented with calibrated RTD temperature monitors.
