Cape Elizabeth officials are considering proposals that would require retailers to charge a fee for single-use shopping bags and ban the sale and use of plastic foam containers by food vendors.

The proposals mirror ordinances passed in recent years in Portland and South Portland, where retailers must charge 5 cents for single-use paper or plastic shopping bags.

The Town Council has forwarded the proposals to its ordinance committee for in-depth review on Jan. 17, according to the town’s website.

The bag fee would apply to retail stores where food sales account for at least 2 percent of revenue. The plastic foam container ban would apply to all vendors, including school and municipal departments.
