China PP75 flat cover can withstand high temperatures Manufacturers, Supplier

Food-grade PP plastic bowls are made from polypropylene (PP) and are classified as non-toxic, odorless semi-crystalline linear polymers. They possess high-temperature resistance (suitable for long-term use above 100°C), corrosion resistance, and lightweight properties, making them suitable for microwave heating and boiling water sterilization. The products have high surface gloss and excellent sealing and preservation performance, but they have weak low-temperature impact resistance, which requires enhancement of mechanical properties through filler modification. When purchasing, it is necessary to identify raw material safety labels to avoid confusion with ordinary plastics or BPA-containing polycarbonate (PC) materials.

  • Strong temperature resistance: Can withstand high temperatures of 100~120°C (microwave safe) and performs well in freezing environments.
  • Lightweight and cost-effective: Low density reduces transportation costs and is easy to mass-produce.
  • High transparency and customizability: Glass-like transparency and easy to color/print for brand recognition.
  • Environmental advantages: Fully recyclable (plastic number 5) and durable for multiple uses.
  • Moisture-proof and barrier properties: Prevents food from getting damp and can be enhanced via coating.

Feature Highlights

PP Lid: Specifically designed for scenarios requiring microwave heating. The PP material maintains excellent heat resistance while effectively preventing food from absorbing unwanted odors.

Introduction

PP (Polypropylene) is a versatile material used extensively across various sectors. In the industrial sector, it is favored for manufacturing chemical containers, pipes, and mechanical parts due to its corrosion resistance. In the medical field, medical-grade PP is essential for surgical tools and packaging.

In food packaging, it is the standard for food bags, containers, and straws due to its safety and hygiene. Furthermore, PP is critical in automotive and home appliance manufacturing, where it is used for car bumpers, instrument panels, and appliance exteriors because of its strength and electrical insulation properties. With ongoing technological progress, the application of PP continues to expand globally.
