How paper packaging works for ice cream

Recent trends in packaging demand a more environmentally conscious approach to food packaging, including ice cream. While plastic has traditionally been used for individual and family-sized portions of ice cream, paper containers are becoming more popular. However, ordinary paper containers are not ideal for frozen desserts as ice cream is cold and contains moisture, which can cause it to begin melting during storage, transport or consumption. For paper packaging to be effective, it needs to be designed with the right barriers and construction to resist moisture, and Univest packaging https://univest-pack.com/ has successfully met all the challenges:

1. Conventional untreated paper absorbs moisture, meaning that melted ice cream can eventually weaken the material and cause it to become soggy. For this reason, ice cream cups and tubs are generally made using specially treated paperboard or paper-based structures with a moisture-resistant inner barrier. Depending on the application, this barrier may be created using a suitable coating or another layer that is compatible with food contact and prevents liquid from quickly penetrating the paper.
2. A paper container alone does not provide the same thermal protection as specialised insulated packaging. However, ice cream containers do not necessarily need to keep the product frozen for long periods if it is to be served immediately. Additional insulation may be required for takeaway and delivery applications, particularly when the product must remain frozen during an extended journey.
3. A thicker paperboard construction provides more resistance to temperature changes than very thin paper. Double-wall or multi-layer designs can also create an extra barrier between the frozen product and the outside world. However, the exact level of insulation depends on the entire packaging system, not just the thickness of the paper.
4. A well-fitting lid helps to prevent leakage and contamination of the ice cream, while limiting its exposure to warmer air. It should remain securely attached during transportation, yet still be easy for customers to remove. For delivery orders, the closure must also be able to withstand movement and handling without becoming detached.
5. The selected paperboard and barrier must remain stable under frozen or refrigerated conditions, and should not become excessively brittle or lose their structural integrity. Therefore, manufacturers need to test the complete package under the temperatures and handling conditions expected during normal use.
6. Packaging should be considered as part of the wider cold-chain system. Even a well-designed paper cup cannot prevent melting if the product is left outside of suitable temperature conditions for too long. Depending on the delivery distance and applicable food-safety practices, insulated bags, thermal liners, dry ice or other temperature-control measures may be required.

Paper packaging is particularly practical for ice cream shops as it can be manufactured in a variety of sizes and shapes. Small cups can be used for individual servings, while larger tubs can accommodate take-home portions. Packaging can also be printed with logos, colours, illustrations, nutritional information or promotional messages, thereby becoming part of the brand experience.
