As the global leader in temperature assurance packaging, Sonoco
ThermoSafe is recognized for its expertise and advanced solutions. We also realize that our customers require solutions tailored to address the needs of a wide range of shipping conditions.
For that reason, we’ve applied our engineering expertise to create Envoy ®
Insulated Shippers — a simple, economical solution for less complex shipping needs, with testing data and design qualification from ISC Labs.
Our engineers are experts in Ambient Temperature Profiles. Envoy is designed to the ISCsilver™ ambient temperature profile, which reflects more moderate shipping conditions, such as express air and moderate to controlled distribution lanes.
• A simple solution ideal for 1-2 day shipments and small payloads
• Seasonal packouts that are simple to follow and use foam bricks that maintain their shape for easy assembly
• Standard components
• An economical option from Sonoco
ThermoSafe
• A convenient off-the-shelf product with an effective temperature performance
When it comes to shipping temperature sensitive products, one solution doesn’t fit all. If Envoy doesn’t meet your needs, contact us to determine the best solution for your products.
