Biodegradable Alternatives to Aluminum Foil for Food Packaging

Introduction

Aluminum foil is widely used in food packaging due to its excellent barrier properties, heat resistance, and lightweight nature. However, its environmental impact has raised concerns, as aluminum production is energy-intensive, and recycling rates remain low. As a result, businesses and consumers are seeking biodegradable and sustainable alternatives that provide similar benefits while being environmentally friendly.

This article explores the best biodegradable alternatives to aluminum foil for food packaging and their advantages.
