I have not bought any of the Sun Chips with compostable bags yet but if Frito Lay is withdrawing them from the market, then these bags must be very noisy indeed.
According to this article from the USA Today, Frito Lay is returning five of six SunChips flavors on its original packaging after complaints of the compostable bags’ noisiness spread like a virus all across media outlets.
Here’s a YouTube video comparing the noise level of the SunChips bags over other chip bags. SunChips sales are said to have declined more than 11% over the past 52 weeks (excluding Wal-Mart, which doesn’t share its data), according to market research group SymphonyIRI.
As reported by the Green Blog before, the compostable bag uses NatureWorks’ polylactic acid plastic Ingeo in the packaging’s outer print web film and inner barrier web film. The adhesive layer gluing the two films together is also made with other eco-friendly material.
The bag fully decomposes within 14 weeks. Frito Lay said the compostable bag will still be used in the Original flavor SunChips. The company said it is still working on next-generation biodegradable bags.
As everyone knows by now, it ain’t easy being green!
