Most takeaway containers are made from polypropylene (PP). However, PET, PS, HDPE, and PLA are also widely used depending on the food application.
Material choice directly affects food safety, heat resistance, cost, and recyclability. Choosing the wrong plastic can cause container failure, regulatory issues, or added waste costs for your operation.
What Are The 5 Main Plastics Used In Takeaway Containers?
PP (#5) — The All-Rounder For Hot And Cold Food
PP is the most common plastic in disposable plastic takeaway food containers. It handles temperatures from –20°C to 120°C, making it suitable for microwaving, hot soups, and refrigerated storage. PP is widely accepted in kerbside recycling programs globally.
PET (#1) — Clear, Recyclable, Cold-Food Favourite
PET offers excellent clarity and structural rigidity at low temperatures. It is the standard choice for cold food retail displays, salad boxes, and beverage cups. PET is not suitable for hot food — it softens above 60–70°C. Learn more in the PET cups and containers production and recycling guide.
PS (#6) — Lightweight But Controversial
PS (polystyrene) is inexpensive and lightweight. It is commonly found in foam cups and clamshell containers. However, PS has limited heat resistance and poor recyclability. Many markets are actively restricting or banning its use in food packaging.
HDPE (#2) — Sturdy For Heavy-Duty Use
HDPE is a harder, denser plastic used in buckets, tubs, and large disposable plastic takeaway food containers for bulk or institutional foodservice. It resists oils and chemicals well and is one of the easiest plastics to recycle.
PLA (Bio-Based) — The Compostable Alternative
PLA is derived from plant starches rather than petroleum. It is BPI-certified commercially compostable under controlled industrial conditions. PLA is suitable for cold to warm foods, but breaks down under high heat or humidity if stored incorrectly.

How Can You Identify The Plastic In Your Container?
1. Check The Recycling Symbol
Every container carries a resin identification code — a number from 1 to 7 inside a triangle. PP is #5, PET is #1, PS is #6, and HDPE is #2. This number tells you both the material and its recyclability.
2. Use The Feel And Flexibility Test
PP containers feel slightly waxy and flex without cracking. PET is rigid and crinkles when bent. PS snaps cleanly under pressure. HDPE is stiffer and heavier. PLA looks similar to PET but turns cloudy faster when heated.
3. Check Clarity
PET produces the clearest containers. PP is translucent to opaque. PS can be clear or foamy. HDPE is typically opaque. If a clear container softens in warm water quickly, it is likely PLA or PS — not PET.
Which Plastic Is Best For Your Menu?
The right container depends entirely on what you are serving. Use this matrix as a starting point:
| Food Type | Recommended Plastic | Why |
| Hot soups, rice, curries | PP (#5) | High heat resistance, microwave-safe |
| Cold salads, sushi | PET (#1) | Clear, rigid, food-grade |
| Oily or fried foods | PP (#5) or HDPE (#2) | Oil-impermeable, structurally stable |
| Acidic foods (citrus, sauces) | PP (#5) | Chemically inert at low pH |
| Frozen-to-oven meals | CPET | Validated to 220°C, no deformation |
| Eco-compliant markets | PLA or rPET | Compostable or GRS-certified recycled |
Disposable containers with lids for hot food require PP or CPET as a minimum standard. For cold food retail or delivery programs, PET or anti-fog rPET are better suited.
When sourcing disposable plastic containers with lids for food at scale, check the resin code first.
Whether you buy through wholesale, bulk, or direct manufacturers, the material must match your food application. Make sure the plastic suits your food temperature, storage conditions, and handling needs.
What Is The Right Choice For Your Takeaway Packaging Program?
Material selection affects shelf life, food safety compliance, logistics performance, and sustainability reporting. Getting it right at the specification stage prevents costly failures downstream.
SOWINTOP manufactures PP, PET, rPET, CPET, and CPLA food packaging formats across a 110,000 m² facility, supported by a near-100-person R&D team and 30+ years of manufacturing experience. All formats ship FDA, EU 10/2011, GRS, BPI, and BRCGS-compliant as standard, with a 20-day lead time and full OEM/ODM capability for foodservice chains, QSR operators, distributors, and retail programs.

Frequently Asked Questions
What Plastic Is Most Commonly Used In Takeaway Containers?
PP (#5). It handles heat, resists oil, and suits hot food.
Are Takeaway Containers Safe For Hot Food?
PP, HDPE, and CPET are. PET, PS, and PLA are less suitable for high heat.
Can I Recycle My Takeaway Container?
Usually PP, PET, and HDPE. PS is less accepted. PLA needs industrial composting.
What Does The Number Inside The Recycling Triangle Mean?
It identifies the plastic type, such as PP #5 or PET #1.
