Starting July, the EU mandates all plastic caps to be attached to bottles and cartons, stirring mixed reactions.

The law targets all drink packages under three liters to cut down plastic pollution, a growing concern.

While the attached caps annoy many, making spills more likely, advocates argue it's a necessary change.

Johanna Ragnartz of Keep Sweden Tidy highlights the alarming rate of plastic caps found in littering.

Producers are expected to develop more user-friendly designs over time.
