Made in Sweden from the unbleached pulp of Scandinavian spruce trees ? a natural, renewable resource ? If You Care Sandwich and Snack Bags are greaseproof, and provide a natural barrier which prevents grease or fat from penetrating. They are not treated with petroleum based paraffin wax or any other wax. Like all of our If You Care paper products, these sandwich and snack bags are totally chlorine-free, as a result of which, no chlorine is dumped into our lakes, rivers and streams. Perfect for sandwiches, snacks, cookies, muffins, nuts, chips and much more.
