Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a food packaging bag with good heat resistance. Background Technology

[0002] Food packaging bags are a form of packaging design aimed at bringing convenience to life. They come into direct contact with food, ensuring it remains undamaged during transportation and storage through preservation and storage functions. Food packaging bags also prevent food from contacting oxygen and moisture in the air through barrier properties, thus extending its shelf life. The choice of material for food packaging bags is crucial. Commonly used materials include polymers such as polyethylene, polypropylene, polyester, and polyamide. These materials possess different physical and chemical properties to meet the packaging needs of various foods. When selecting packaging materials, it is necessary to comprehensively consider the characteristics of the product, consumer needs, and environmental requirements.

[0003] Heat-resistant food packaging bags are typically made of polypropylene, a type of plastic bag that is more durable than PE bags. It has properties such as high transparency, heat resistance, bend resistance, and resistance to breakage. However, existing heat-resistant food packaging bags usually have certain defects. They are usually designed with a one-time sealing structure, which means that the packaging bag cannot be resealed after it has been opened, so it cannot continue to preserve food and cannot be reused. In addition, the inside of the one-piece food packaging bag is not easy to clean, and it is inconvenient to store other items after use. It is also not environmentally friendly. Therefore, there is a need for an environmentally friendly food packaging bag with good heat resistance. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a food packaging bag with good heat resistance. This solves the problem that existing heat-resistant food packaging bags are usually designed with a one-time sealing structure, which makes it impossible to reseal the packaging bag after it is opened and reused. In addition, the inside is not easy to clean, making it inconvenient to store other items after use, which is not conducive to environmental protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a food packaging bag with good heat resistance, comprising a food packaging bag and a detachable heat-insulating base assembly, the detachable heat-insulating base assembly comprising an annular shell, a heat-insulating base, a slot, a heat-insulating bottom plate, a locking block, an anti-slip ridge, and a return spring, the annular shell being fixedly connected to the outer surface of the food packaging bag, the heat-insulating base being disposed at the bottom of the annular shell, the slot being formed on the surface of the annular shell, the heat-insulating bottom plate being fixedly connected to the top of the heat-insulating base, the locking block being slidably connected to the inside of the heat-insulating bottom plate, the anti-slip ridge being fixedly connected to the surface of the locking block, and the return spring being fixedly connected to the inside of the heat-insulating bottom plate, the return spring being fixedly connected to the locking block, and the locking block being slidably connected to the inside of the slot.
