Microwave food packaging bags

The new generation of microwave food packaging bags produced by Shanghai San Ying Packaging Materials Co., Ltd. is suitable for a wide range of applications, ranging from liquid foods to solid foods, and can be freely selected for refrigerated, high-temperature cooking two specifications and different barrier material requirements. The bag can be heated in a completely sealed state, without opening or opening, it will not cause secondary pollution to the food in the bag, and avoid the loss of nutrients and taste of the food. It also avoids heating or heating of the traditional microwave package. Uneven situation occurs.

The bag has a special inner membrane and a uniquely designed pressure relief device at the steam vent. After heating in a microwave oven, the steam in the bag reaches a certain pressure, and the steam port can be automatically opened to the most suitable size, and steam can be safely discharged outside the bag. Moreover, even if the content is a liquid, it will not leak from the steam vent, which avoids the situation of the conventional microwave food bag bursting under high temperature and high pressure. The unique pressure-relief design keeps the steam inside the bag under a certain pressure during the heating process. After a part of the steam is discharged from the steam outlet outside the bag, the bag is still filled with steam, so that the food is heated evenly and the heating time is shortened.

The bag has a novel design and environmental protection, and can be directly used as an alternative to the existing microwave food packaging film and sealed container, which can greatly reduce costs. At the same time, the bag uses a transparent high barrier material instead of aluminum foil, can be recycled and used, in line with international environmental protection concept, and can operate on the original packaging equipment.
