Final answer:
SunChips were once sold in a compostable bag that crinkled at 95 decibels, which faced consumer backlash due to the loud noise, leading the company to revert to traditional packaging.
Step-by-step explanation:
The brand of chips that was once sold in a bag that crinkled at 95 decibels is SunChips. In 2010, Frito-Lay introduced a compostable bag made from plant-based materials for their SunChips product line. However, the initiative faced criticism as the bags were noticeably louder than traditional chip packaging, with the crinkling noise measured at 95 decibels, which can be compared to the noise level of a busy street. Due to consumer complaints, the company eventually returned to a quieter, but less environmentally friendly packaging option.
