Can Cardboard Protect Wine from an Explosion? 'VS Cardboard: Explosion' Out June 3

KAYAC Inc. has produced the second installment of the 'VS Cardboard' video series, 'Explosion Edition,' for Sakura Paxx Co., Ltd., a cardboard manufacturer based in Toyama Prefecture. The video, set to be released on Sakura Paxx's official YouTube channel on June 3, 2026, tests whether a wine bottle strictly packaged in cardboard can survive the impact and flames of a massive explosion.

Following the success of the first video, which featured a 100-meter drop from a helicopter, Sakura Paxx engineers took on their president's challenge to create an explosion-proof cardboard structure. This initiative serves as a recruitment campaign to showcase the potential and social value of cardboard to job seekers.

Additionally, a commemorative giveaway campaign runs from May 20 to June 19, 2026, on the official X account (@SAKURAPAXX). By following the account and quote-reposting the campaign post with an idea for the next 'VS Cardboard' challenge, three lucky winners will receive the rocket-shaped 'strongest cardboard' featured in the previous helicopter video.
