Ice cream containers are primarily made from a special type of paperboard designed to withstand the harsh conditions of freezing temperatures.
The Material: Wet-Strength Paperboard
The key material is wet-strength paperboard. This isn't your average cardboard. It's engineered to resist the moisture and cold of freezers. This is achieved through a special manufacturing process.
Key Properties of Wet-Strength Paperboard:
- Resistance to moisture: The paperboard's structure prevents it from becoming soggy or disintegrating when exposed to cold, potentially wet ice cream.
- Strength at low temperatures: The material maintains its structural integrity even when frozen, preventing tears and damage.
The Construction: Paperboard and Plastic Lining
To further enhance its durability and prevent leakage, the wet-strength paperboard is often lined with polyethylene plastic. This plastic lining acts as a barrier against moisture and prevents the ice cream from soaking into the container and weakening the paperboard. This combination ensures that the container remains intact and prevents ice cream from becoming freezer-burned.
Additional Considerations:
- The manufacturing process involves specialized machinery to create the specific shape and size of the ice cream container.
- Printing processes are used to apply branding and other information to the exterior.
Other products using this same wet-strength paperboard include frozen food boxes and beverage carriers, highlighting its versatility and suitability for cold storage.
