What Are Insulated Shipping Bags?
Insulated shipping bags are a versatile and efficient solution for transporting temperature-sensitive products safely and securely. Designed to maintain consistent internal temperatures, they protect goods such as fresh food, pharmaceuticals and perishable samples from heat, cold and moisture during transit.
At Hydropac, we specialise in developing high-performance insulated bags that combine functionality, durability and sustainability. Built with advanced thermal insulation materials and a secure sealing system, our bags offer reliable protection for every delivery. Whether used for home food deliveries, medical shipments or chilled e-commerce goods, Hydropac’s insulated bags ensure products arrive fresh, safe and at the right temperature.
Discover Insulated shipping bags
Reliable Temperature Control for Real-World Deliveries
In modern cold chain logistics, insulated shipping bags provide lightweight protection with strong thermal performance. They keep temperature-sensitive goods stable through depot dwell times, courier routes and doorstep delays, without the bulk of rigid containers.
Hydropac designs insulated shipping bags for sectors where precision matters, including food, pharmaceuticals and laboratory shipments. Each bag creates a controlled microclimate that shields contents from external temperature swings and routine handling, so products arrive in the right condition.
Built Around Hydropac Coolants
Performance starts with the right coolant. Pair Hydropac insulated bags with Ice Packs by Hydropac in either water-based or gel formulations to achieve the target range for the full delivery window. Cooling loads are sized to the route profile, helping maintain chilled conditions at 2–8°C or frozen conditions down to −18°C when correctly configured. Our coolants are produced using seal through water technology for a hygienic, leak-resistant finish that stands up to repeat freeze cycles.
Wool Postal Pockets for Smaller Shipments
Not every consignment requires a bag. For compact items that still need temperature protection, Hydropac’s Wool Postal Pockets provide a natural insulation option that is well suited to e-commerce and sample logistics. They are easy to pack, space efficient and designed to complement our ice packs for short to medium transit times.
Their durability, reusability and proven performance make them a dependable choice for temperature management, while Hydropac’s complementary range of recyclable cooling products provides sustainable options for the future of cold chain logistics.
Practical Features That Matter
Hydropac insulated shipping bags are engineered for dependable day-to-day use across busy delivery networks. Typical features include secure closures, wipe-clean interiors and durable outer layers that resist scuffing and compression. The result is packaging that protects against common in-transit risks while remaining easy to handle at the pack bench.
Why operators choose Hydropac insulated bags:
- Consistent thermal performance when paired with correctly conditioned ice packs.
- Lightweight format to reduce shipping weight and improve courier efficiency.

Validated for the Cold Chain
Every configuration is tested in Hydropac’s climate chamber against realistic courier timelines and seasonal ambient profiles. This validation helps businesses meet Good Distribution Practice requirements for medicines and Food Standards Agency expectations for temperature control. It also reduces spoilage risk by ensuring the bag and coolant work together as a single, predictable system.
Hydropac’s approach combines tested insulation, proven coolants and practical form factors. The outcome is a family of insulated shipping bags and supporting components that deliver stable temperatures, efficient packing and dependable performance from dispatch to delivery.
