Description

Technical Field

[0001] The invention relates to the technical field of packaging bags, and in particular to an environmentally friendly, large-capacity, heat-insulating and portable food packaging bag. Background Art

[0002] Food packaging bags are bags used to package food. They have many important functions. From the perspective of materials, there are many types such as plastic, paper, and composite materials. For example, common potato chip packaging bags are mostly made of plastic, which can effectively prevent potato chips from being crushed and block oxygen to prevent potato chips from oxidizing and deteriorating. Food packaging bags can provide protection to prevent food from being physically damaged, such as collisions and squeezing. At the same time, they can also block external pollutants such as dust and microorganisms. It can also play a certain role in preserving freshness. Some packaging bags can adjust the internal gas composition and extend the shelf life of food.

[0003] In daily life, most of the common food packaging bags we see are designed with an opening at the top. This traditional bag is widely used in the field of food packaging. However, as people's requirements for food quality and packaging convenience continue to increase, its limitations are becoming increasingly prominent. For freshly made food, such as freshly baked bread and freshly fried dough sticks, people want them to maintain temperature and taste delicious, but also need proper ventilation to prevent the surface of the food from becoming soggy and soft due to water vapor accumulation, affecting the taste. However, it is difficult for current ordinary food packaging bags to take both of these into account.

[0004] In addition, traditional food packaging bags have many disadvantages. In terms of capacity, they are usually small. Once more food needs to be packaged, the bag will easily fall after the capacity is expanded. This not only causes the hand to be squeezed when carrying, which brings great inconvenience to consumers, but also makes the food easily roll over in the bag when placed directly on the table, which is extremely unstable. If there are multiple different types of food in the bag, it is easy to mix them together, which is not only unhygienic, but also affects the original flavor and quality of the food.
