For users seeking efficient, sustainable food storage solutions, we are thrilled to announce the launch of our precision-engineered Advanced Food Sealing Lid—also a high-performance food cover from Yinghua, designed to redefine freshness retention through its cutting-edge sealing technology.

The standout feature of this innovative food cover is its post-cooking negative pressure preservation function, the core of its food freshness extension capability. Unlike ordinary food storage lids or silicone lids that merely cover food without forming a tight seal, this Yinghua food cover utilizes state-of-the-art vacuum-sealing technology to create a complete airtight environment immediately after food is cooked. As soon as the food is ready, the lid seamlessly activates negative pressure suction, extracting excess air from the container to eliminate oxygen—one of the primary culprits behind food spoilage. By isolating food from oxygen, this negative pressure seal significantly slows down the oxidation process that causes ingredients to lose their original color, flavor and nutritional value. It also effectively inhibits the growth and reproduction of harmful microbes and bacteria, which are prone to multiplying in oxygen-rich environments and leading to food deterioration. This means cooked food, whether it’s delicate vegetables, tender meats, flavorful soups or freshly baked pastries, can maintain its just-cooked taste, tender texture and essential nutrients for far longer. Compared to traditional food storage methods or common silicone lids, the negative pressure preservation function of this food cover extends food freshness by up to 50%, ensuring that every bite retains the same deliciousness as when it was first prepared, while also reducing unnecessary food waste caused by spoilage.

Complementing its exceptional negative pressure preservation performance is the patented quick-release pressure valve, engineered with both efficiency and safety in mind to enhance the user experience of this food storage lid. After the negative pressure sealing process, the container remains in a sealed, low-pressure state, which could make opening the lid difficult or even cause spills if forced. To solve this problem, the Yinghua food cover is equipped with a one-touch quick-release pressure valve, a patented design that sets it apart from ordinary silicone lids and food covers. With a simple press of the valve, it instantly equalizes the internal and external pressure of the container, eliminating the suction force and allowing the lid to be opened easily and smoothly. This not only simplifies the operation process but also ensures safety—preventing hot steam or food from splashing out when opening the lid, which is particularly important when handling freshly cooked, high-temperature food. The quick-release pressure valve also adds convenience for repeated use: after opening and taking food, users can reactivate the negative pressure sealing function without any cumbersome steps, maintaining the freshness of the remaining food efficiently. This patented design fully considers the actual usage scenarios of users, making the advanced sealing technology more user-friendly and practical.

Suitable for both home and professional use, this premium food storage lid from Yinghua embodies our brand’s commitment to integrating smart technology into daily food storage, focusing on delivering exceptional sealing performance to users.

By blending superior negative pressure sealing performance and user-friendly design, we empower users to reduce waste, save costs, and maintain consistent food quality. Interested in integrating this advanced food cover into your life or business?
