Few stores offer clamshells exclusively, he added, but most offer at least some clamshells.
The company plans to offer bicolor and tricolor packs for the first time this year, with two colors of grapes available in 2-pound clamshells and three colors in 4-pound containers.
But not everyone is a clamshell fan.
Nick Dulcich, an owner and director of sales for Jakov P. Dulcich & Sons, Delano, Calif., said some regional chains don’t take the clamshells because they cost too much.
“We’re a premium shipper,” he said. “If we pack in that thing, we’ll have a $10 cost.”
To counter the higher cost, some shippers pack smaller, third-quality fruit in the containers so they can retail at a more favorable price, he said.
“It’s kind of a scam,” he said, adding that a large bunch of premium fruit likely would not fit in a clamshell container.
Dulcich said his company will pack clamshells to order.
He asks customers to notify him a few days in advance if they want the containers.
