Is PP Plastic Sheet the Best Material for Thermoforming Disposable Lunch Boxes?

What Is PP Plastic Sheet for Thermoforming?

Polypropylene (PP) plastic sheet is a lightweight, food-grade thermoplastic material widely used in thermoforming disposable lunch boxes, takeaway containers, and microwave-safe trays. With excellent heat resistance, impact strength, and chemical stability, PP is considered one of the most reliable materials for hot food packaging applications.

At PULIXIN, we produce high-quality PP plastic sheets in roll or cut sheet form that are ideal for high-speed thermoforming machines. Available in customized thicknesses, colors (white, transparent, or black), and with optional additives (anti-fog, anti-static, high clarity), our PP sheet rolls are suitable for both automatic and manual forming processes.

Why Choose PP Sheet for Lunch Box Thermoforming?

PP sheet offers several unique properties that make it ideal for disposable food containers:

• High Heat Resistance (up to 120°C) – Microwave and hot-fill safe
• Food Contact Approved – BPA-free, non-toxic, odorless
• Flexible & Crack-Resistant – Maintains shape during forming and use
• Recyclable & Eco-Friendly – Conforms to sustainable packaging trends
• Cost-Effective for Mass Production – Low material weight, excellent yield
