A major Japanese discount chain in Hong Kong has begun packaging sushi in cardboard boxes following the city’s plastic ban. While some customers prefer the traditional transparent plastic boxes for better visibility and perception of freshness, others prioritize comfort and air conditioning in the store’s seating area. However, the cardboard boxes offer no visual guidance on the sushi’s appearance, raising concerns about presentation and hygiene. The store has posted notices reminding customers of the plastic ban and encouraging the use of cardboard boxes for dine-in. Some customers express concerns about not being able to inspect the freshness of the sushi in cardboard packaging, while others believe the freshness should be consistent regardless of packaging. The ban’s grace period allows businesses time to adapt, but offenders may face fines.
