The need for packaging innovation

Impractical stickers and hazardous staples

Major foodservice and restaurant brands are leaning more heavily than ever on third-party food delivery platforms, yet a persistent packaging issue remains through these delivery channels.

Once delivery bags leave restaurant premises, foodservice brands lose control over the security of the packaged food. Delivery bags can easily be opened, resulting in a surge of customer complaints reporting missing items. This poses a significant operational cost, both for restaurant brands and their third-party delivery platforms.

Foodservice brands have attempted to deal with this issue through a number of approaches, each of which has shown notable disadvantages.

Stickers placed over closed delivery bags increase packaging costs, create additional packaging items that complicate stock management, and present a challenge in ensuring seal labels are consistently applied correctly.

A common alternative solution, staples also present a number of issues. This primarily centres around food safety concerns either when sealing or opening the bag.
