Why Cardboard Gets Soggy in the Freezer (And How Packaging Solves It)

The Freezer Moisture Problem

If you've ever put cardboard in the freezer, you know what happens.

It gets soft and soggy.

This happens because paperboard absorbs moisture.

Freezers create humidity cycles that cause condensation on packaging.

Without protection, cardboard begins to weaken.


The Solution: PE Coated Paperboard

Many frozen dessert boxes use PE coated board.

PE stands for polyethylene, a thin plastic layer applied to the surface of the paperboard.

This coating:

• blocks moisture
• prevents absorption
• maintains structural integrity


Common Applications

PE coated board is used for:

• frozen cheesecake boxes
• ice cream containers
• frozen pie packaging
• frozen pastry cartons

Without this coating, packaging would quickly degrade.


Designing Frozen Dessert Packaging

When designing packaging for frozen baked goods, you need to consider:

• freezer durability
• moisture barrier
• stacking strength
• branding visibility

At Cheetah Pak, we help bakeries design freezer-ready packaging systems that balance protection and brand presence.
