Polypropylene (PP) disposable food containers are widely used in the food service industry, households, and catering businesses globally, favored for their excellent performance, safety, and cost-effectiveness. Below is a detailed introduction to their core characteristics, advantages, applications, and environmental considerations.
Polypropylene (chemical formula: (C₃H₆)ₙ) is a thermoplastic polymer derived from propylene monomer. It is recognized as one of the safest food-contact materials by regulatory bodies worldwide, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA).
A key identifier for PP products is the recycling symbol “5” (stamped on the bottom of containers), which helps consumers and recyclers distinguish PP from other plastics (e.g., PET “1”, PE “2”).
PP disposable food containers stand out due to their unique physical and chemical traits, making them ideal for food storage and transportation:
