Japanese snack makers reduce plastic packaging

Japan's major snack-food makers are trying to go green by reducing plastic packaging.

This month, Calbee started using paper as a main material for packages of some potato-chip products. The bags contain half as much plastic as before.

Potato-chip packaging has a plastic film to maintain the chips' taste and crispy texture. Calbee officials say their technology enables them to make the film thinner and to combine it with paper.

Calbee's goal is to halve its reliance on petroleum-derived plastics for packaging by 2030.

Koike-ya is also using paper for packages of some products, including potato chips.

Lotte employs thinner plastic for chewing-gum containers and chocolate packages.

The companies say the moves cut their plastic reliance by more than 10 percent.
