Karo corn syrups pour into PET

Karo corn syrup debuted in 1902 in “friction-top tins,” then was filled into glass bottles for decades. This summer, Karo corn syrup made a bold step into monolayer PET bottles, supplied by Amcor PET Packaging.

Besides the move to PET, Karo’s 16-oz venerable light, dark, and pancake syrups were joined by a new brown sugar syrup variety.

Amcor injection/stretch blow-molds the bottles, then ships the 30-gram bottles to the Summit, IL, plant of ACH Food Companies, Inc., the Memphis-based food manufacturer that purchased the Karo syrup brand from Unilever two years ago. To accommodate the PET bottles, the plant added a new filler, capper, labeler, case packer, bottle handling, and conveying equipment.

Erin Shackelford, ACH’s brand manager, tells Packaging World that the syrup is hot-filled, though she wouldn’t reveal the specific fill temperature. “It was quite a challenge to fill them without [bottles] returning back to their preform shape,” she says, “but that’s what Amcor’s technology permits. We chose Amcor for these bottles because we had worked with them on other projects.”
