Modern plastic jars often come with user-friendly features that are difficult or expensive to achieve with other materials:
Wide Mouths: Easy to scoop out product.
Secure Lids: Prevent leaks and spills.
Stackable: For easy storage.
Recyclable: Many plastics used in jars (like PET #1, HDPE #2, and PP #5) are widely recyclable, though local facilities vary.
Lightweight: As mentioned, its light weight reduces transportation emissions.
Innovation: The industry is rapidly advancing with the use of Recycled Materials (e.g., PCR - Post-Consumer Recycled plastic) and Bio-based Plastics made from renewable resources like sugarcane.
