Custom PP140 bowl lid can withstand high temperatures Manufacturer, Factories

Food-grade PP plastic bowls are made from non-toxic, odorless polypropylene (PP), a versatile thermoplastic polymer known for its durability and safety in food contact applications. These bowls offer high-temperature resistance, capable of withstanding temperatures above 100°C, making them suitable for various cooking methods including microwave heating and boiling water sterilization. Additionally, they exhibit excellent corrosion resistance, ensuring longevity even when exposed to acidic or alkaline substances. The lightweight nature of PP plastic makes these bowls easy to handle and transport, adding convenience to their practicality.

Key features of food-grade PP plastic bowls include a high surface gloss that enhances aesthetic appeal and makes cleaning easier. Their excellent sealing properties ensure that food remains fresh for longer periods, reducing waste and maintaining nutritional value. Preservation performance is another significant advantage, as these bowls can effectively maintain the integrity of food items over time without leaching harmful chemicals.

However, it is important to note that PP plastic has weak low-temperature impact resistance, which means it may become brittle and prone to cracking at very low temperatures. To mitigate this issue, manufacturers often incorporate filler modifications to improve the material's overall performance across different temperature ranges. Ensuring the use of raw materials that meet food safety standards is crucial to avoid confusion with ordinary plastics or potentially hazardous materials such as BPA-containing polycarbonate (PC) plastics. Proper labeling and adherence to regulatory guidelines help guarantee the safety and reliability of food-grade PP plastic bowls.
