Foodservice Industry Navigates Sustainable Packaging Choices

Structure and selection of paper-based cups

Modern disposable cups are made primarily from cellulose-based paperboard. To give the container the liquid barrier it needs, manufacturers typically apply a polyethylene (PE) film to the inner surface or to both sides of the board. For hot drinks, single-sided coating is the most widely used approach. Water-based barrier coatings have also entered the market as an alternative technology.

For restaurants and HoReCa operators — hotels, restaurants and cafes — safety is the first procurement criterion. Low-grade plastic coatings can release harmful substances at high temperatures and compromise food safety. Buyers are therefore advised to prioritise suppliers certified to international quality standards such as FSSC 22000 and ISO 9001:2015, ensuring the product does not alter the taste or aroma of the beverage it contains.

Environmental misconceptions and sustainability

A common industry assumption holds that reusable tableware — ceramic or glass cups among them — is always the more sustainable option. In practice, the water, energy and detergent required to wash those items often produce a larger environmental footprint than disposable cups. The labour cost of washing is also an operational factor that food-service businesses must weigh.

From a hygiene standpoint, single-use paper cups carry a clear advantage in reducing the risk of infection transmission, a point of particular weight at a time of heightened public-health sensitivity. At the recycling stage, a soaking process separates paper fibre from the plastic film, and the recovered cellulose can be returned to the cycle. Although recycling itself consumes labour and energy, paper-based packaging generally has a more contained negative impact across its full lifecycle than plastic alternatives.

Performance limits and how to manage them

Even certified cups of high quality have limitations in real-world use, and buyers need to balance them against the demands of their operation:

• Heat resistance: structural stability at specific temperatures should be confirmed before purchase.
• Moisture absorption: after prolonged storage, paper materials may lose performance under ambient humidity.
• Recycling infrastructure: the effectiveness of cup recycling depends heavily on local waste-handling facilities.

Expert guidance: cutting waste at the source

Operators are encouraged to adopt low-waste production strategies, tightening inventory management to prevent the build-up of raw material and selecting suppliers that treat material efficiency and end-of-life responsibility as core design priorities. As emphasised at Packaging Innovations & Empack 2026 in Birmingham, the future of the packaging sector lies in a close integration of manufacturing craft and sustainable design.
