What Is a Vacuum Sealed Dry Ice Pack Sheet?

Definition and Composition

A vacuum sealed dry ice pack sheet is a thin, sealed pouch that contains solid CO₂ pellets or blocks. The pouch is vacuum sealed to remove excess air and moisture, preserving the dry ice and slowing heat transfer. At atmospheric pressure, solid CO₂ sublimates directly into gas instead of melting, which keeps products dry. The sheet’s flexible design allows it to wrap around meals, vials or other items, distributing cold evenly and minimizing thermal shock.

These pack sheets typically consist of three layers:

Inner refrigerant core – solid CO₂ pellets or blocks deliver ultralow temperatures down to −78.5 °C.

Vacuumsealed pouch – an airtight film or nylon barrier prevents moisture ingress and keeps CO₂ inside while allowing gas to vent slowly through microperforations.

Outer protective layer – a moisture barrier made of LDPE or foil provides strength and minimizes condensation.

This construction allows the sheet to remain lightweight and easy to handle while delivering powerful cooling for 24–72 hours depending on its size and insulation.

Vacuum Insulated Panels vs. Vacuum Sealed Pouches

It’s important to distinguish between vacuum sealed dry ice pack sheets Dan vacuum insulated panels (VIP). The latter are rigid insulation panels with air removed to create a vacuum, dramatically reducing heat transfer. According to Aztec Container’s 2025 memandu, VIPs are a premium insulation option that “remove almost all air between panels, creating an incredibly effective barrier against heat transfer”. By pairing VIPs with dry ice, shipments require less ice, save weight and maintain precise temperature control. Vacuum sealed pack sheets focus on the refrigerant itself; VIPs are part of the outer packaging and can be used with dry ice sheets to boost performance.

How Vacuum Sealed Dry Ice Pack Sheets Work

Sublimation Science Simplified

Es kering (co₂ solid) does not melt; it sublimates directly to gas at −78.5 °C. When the CO₂ inside a vacuum sealed pack sheet absorbs heat from its surroundings, it transitions to gas and draws thermal energy away from the shipment. Because there’s no liquid phase, no water accumulates, preventing soggy boxes or damaged labels. The vacuumsealed barrier slows this heat exchange by reducing convection and keeping the cold concentrated inside the pouch.

Step by Step Cooling Process

Preconditioning – prefreeze the vacuum sealed dry ice pack sheet or fill refillable cells with dry ice pellets while wearing insulated gloves. Preconditioning ensures the sheet starts at its coldest temperature.

Penempatan – position the sheet on top of or around the product. Udara dingin tenggelam, so top placement provides even cooling; surrounding placement offers longer duration.

Sublimation and venting – as the dry ice absorbs heat, CO₂ gas escapes through microvents or container vents. Never seal a dry ice sheet in an airtight container; proper venting prevents dangerous pressure buildup.

Lamanya – a properly insulated and vacuum sealed dry ice sheet maintains temperatures from −78.5 °C to −18 °C for 24–72 hours depending on size and insulation quality.

Why Vacuum Matters

Vacuum sealing eliminates air pockets inside the sheet. Without trapped air, conduction and convection are minimized, so the cold energy from the dry ice stays focused on the product. Removing air also reduces moisture, preventing freezer burn and ensuring that gases vent in a controlled manner rather than causing the pouch to balloon. When paired with VIPs, the overall thermal efficiency improves further. Misalnya, 2025 guidelines suggest that switching from standard foam to vacuum insulated panels can reduce dry ice needs by 20 %.

Choosing the Right Vacuum Sealed Dry Ice Pack Sheet

Faktor kunci

Selecting the correct pack sheet requires careful consideration of your shipment’s requirements:

Duration and temperature range – mini sheets maintain −20 °C for 24 jam, while larger disposable sheets hold −18 °C to −78.5 °C for up to 72 jam. Match the sheet size to your transit time.

Sensitivitas produk – pharmaceuticals and biologics often require temperatures below −70 °C. A biotech case study described using mini dry ice foam sheets inside vacuum insulated shippers to maintain mRNA vaccine potency during a 36hour flight.

Weight and volume – heavier products absorb more heat. Gunakan 1:1 aturan: allocate about one kilogram of dry ice per kilogram of product for 24 jam. Increase the ratio by 15–20 % for hot climates or extended transit.

Kualitas isolasi – VIPs require less dry ice than standard foam because of their superior thermal resistance. Basic cardboard boxes offer minimal insulation and require more ice.

Kepatuhan Pengaturan – carriers like FedEx classify dry ice as UN 1845, requiring labels and weight declarations. Check your carrier’s maximum dry ice limits (MISALNYA., 200 kg for FedEx, 2.5 kg for many postal services).

According to Insulated Products Corp., after vacuum sealing your product you should assemble your insulated packaging with highperformance liners like PopupLiner or other vacuum insulated panels. Avoid flimsy molded coolers that compress easily and lead to poor insulation.

Prepare the product – vacuum seal or wrap items to prevent freezer burn and moisture exposure. IPC advises vacuum sealed packaging to prevent freezer burn before placing meat inside an insulated box with gel packs or dry ice.

Precondition the sheet – freeze the sheet or fill its cells with dry ice pellets while wearing insulated gloves. Prefreezing ensures maximum cooling power.

Place the sheet – lay the sheet on top of the payload for shorter journeys, or surround the product for longer trips. Use multiple sheets for heavy loads or extended durations.

Vent properly – ensure the container has vent holes or breathable membranes. Never seal dry ice in airtight bags or boxes. IPC’s PopupLiner design allows gas to offgas safely to prevent pressure buildup.

Label – clearly label packages with “Dry Ice (Dan 1845)” and indicate the net weight.

Memantau – use data loggers or IoT sensors to track internal temperatures. Itu 2025 guide recommends logging both core and wall temperatures during bench testing and realworld lane pilots.

Safety Gear and Handling Tips
