Permanent flavors include original, Harvest Cheddar, French Onion, Sweet and Spicy BBQ,and Garden Salsa. Current limited edition flavors include Honey Graham and Apple 'n Caramel. A previous limited edition flavor was Cinnamon Crunch early in 2007 (the flavor is still produced as a seasonal item in the US, reappearing near the end of the year for the holidays), the first time sweet flavors were added since Apple Cinnamon and Honey Nut in 1999.
In the past, some Frito-Lay brand seasoned products, including some flavors of Sun Chips, contained pork enzymes in addition to herbs, cheese, and other seasonings. Frito-Lay's web site states that they use enzymes from pigs (porcine enzymes) in some of their seasoned snack products to develop "unique flavors". The presence of pig-derived ingredients made them haram (forbidden) for Muslims, not kosher for Jews, and not vegetarian. As of April 5, 2011, Frito-Lay's online list "U.S. Products Made Without Pig (Porcine) Enzymes" catalogs nine flavors of Sun Chips "made and distributed in the U.S." that do not contain porcine enzymes.
In April 2008, Frito Lay introduced compostable packaging for the SunChips product line. The bag is made of plant-based material. It will break down within 14 weeks in a hot, active compost pile.
In October 2010, Frito-Lay stated that the compostable package would be pulled back in the United States. The bag created excessive noise, which prompted Facebook groups and complaints. In response to various complaints, Frito Lay announced that they would only use the compostable bag for original flavor chips from the SunChips US line moving forward. The other US flavors will use traditional SunChips packaging.
On February 24, 2011, Frito Lay announced that they were releasing a new, quieter biodegradable bag starting with the Original Sun Chip brand. Closely resembling traditional bags, the compostable packaging uses adhesives sandwiched between the outer and inner layers of the bag to substantially reduce the excessive noise. Current bags are not labeled as compostable, as of 2015.
