Microwave-Safe Black PP Base Tray — A Safe and Practical Food-Grade Polypropylene Container

This product is a food-grade black polypropylene (PP) container, specifically designed for microwave heating applications. It is widely utilized in sectors such as ready-to-eat meal kits, takeout packaging, frozen food trays, and supermarket pre-packaged goods, balancing both aesthetic appeal and functional utility.

PP is the only plastic material internationally recognized as safe for use in microwave heating. This base tray is manufactured using high-purity, food-grade PP raw materials. It complies with regulatory standards for plastic materials and articles intended for food contact, and is free from harmful substances such as BPA and plasticizers, thereby ensuring that no toxic components are released even under high-temperature conditions.

In terms of heat resistance, this black PP base tray can withstand continuous operating temperatures of up to 120°C, fully meeting the requirements for standard microwave heating (where the internal temperature of food typically does not exceed 100°C). With a melting point ranging from 160°C to 170°C, the tray will not soften or deform under normal usage conditions. Please note: When heating, any lids made of non-PP materials (such as PET or PS) should be removed. Additionally, users should avoid prolonged high-power operation while empty, or heating foods with extremely high fat content (such as fried chicken or butter), to prevent localized overheating.

The black finish not only enhances the product's visual quality but also provides a degree of light-blocking capability, helping to protect light-sensitive contents. Furthermore, the PP material itself possesses excellent rigidity, impact resistance, and sealing compatibility, facilitating secure heat-sealing with lid materials such as aluminum foil or composite films to ensure safety during transport and storage.

Moreover, this base tray offers full-temperature-range functionality—from deep freezing (-30°C) to microwave heating. It is suitable for reuse and is 100% recyclable, aligning perfectly with current trends in sustainable packaging.
