PP vs PET Plastic - Choosing the Right Material
PP vs PET Plastic: Choosing the Right Material for the Hospitality Industry
In the ever-evolving hospitality and foodservice industry, selecting the right packaging material is more than just a practical decision — it's a strategic one. With growing emphasis on sustainability, food safety, cost-efficiency, and presentation, understanding the differences between PP (Polypropylene) and PET (Polyethylene Terephthalate) plastics can help hospitality businesses make informed choices for their packaging needs.
What is PP Plastic?
Polypropylene (PP) is a versatile plastic known for its high heat resistance, durability, and lightweight nature. It is widely used in food containers, microwaveable trays, and takeaway packaging.
Key Benefits of PP in Hospitality:
-
🔥 Heat Resistance: PP can withstand temperatures up to 120°C, making it ideal for hot food applications like microwaveable meal trays and lids.
-
💪 Durability: Tough and flexible, PP packaging resists cracking under pressure, which is perfect for takeout and delivery services.
-
💧 Moisture Barrier: Prevents food from becoming soggy or leaking — crucial for saucy or oily dishes.
-
♻️ Recyclability: Classified as #5 plastic, PP is recyclable in many local council programs.
What is PET Plastic?
Polyethylene Terephthalate (PET) is best known for its clarity and strength. It’s commonly used in cold food containers, beverage bottles, and salad bowls.
Key Benefits of PET in Hospitality:
-
👀 Crystal Clear Presentation: PET is highly transparent, enhancing visual appeal — ideal for cold salads, desserts, or drinks.
-
❄️ Cold Application Strength: Withstands refrigeration and freezing, maintaining structural integrity for cold storage.
-
♻️ Recyclability: Widely accepted as #1 plastic, PET is among the most recycled plastics globally.
-
♻️ Eco Appeal: Many PET products are now made from rPET (recycled PET), helping businesses boost their sustainability credentials.

Which One is Better for Your Business?
It depends on what you're serving:
-
Cafés & Takeaway Restaurants: PP containers are ideal for hot soups, noodles, curries, and microwave-ready meals.
