With the gradual popularization of online food ordering services, the takeaway industry is developing rapidly, and the takeaway delivery workers shuttling through the streets and alleys have become a landscape of modern cities.

There are many kinds of takeaway food, and most of them need to be kept warm. Nowadays, most of the boxes used by delivery workers are made of traditional polystyrene foam, which has high thermal conductivity and poor heat preservation performance, and can't meet the heat preservation requirements of customers for takeaway food in high temperature summer and cold winter or other bad weather conditions.

On the other hand, the traditional polystyrene foam has very low strength and poor toughness, and the takeaway delivery box made of this material is very easy to be damaged, which greatly reduces its service life.

Currently, polyurethane rigid foam is a kind of excellent thermal insulation material generated by the reaction of polyether polyol and isocyanate, which has excellent thermal insulation performance, mechanical strength, acoustic performance and chemical resistance, and is widely used in the field of refrigerator and freezer, wall insulation, pipe insulation and so on.

Based on the actual needs of the takeaway delivery industry, the takeaway delivery box is prepared to pursue its low thermal conductivity and high mechanical strength, as well as the safety of the material. Takeaway delivery boxes need to have good impact resistance and deformation resistance, so the toughness of the material puts forward high requirements. Therefore, with high mechanical strength, low thermal conductivity, high toughness, can meet the takeaway delivery box with polyurethane rigid foam material has great application value.

Aluminum foil + polyurethane composite panel, the material is more secure, whether it is hot summer or cold winter, can perfectly achieve long-lasting insulation such as freshly baked.

Not only that, the polyurethane insulation box is more widely used:

1, suitable for the cold chain health industry need to be refrigerated and insulated goods and companies. For example: biological preparations, vaccines, blood, blood products, health epidemic prevention stations, biological vaccine companies, drug logistics, and other distribution and storage.

2. It is suitable for food industry which needs cold storage and freshness of food in large quantities for storage or transportation. For example: fruits, vegetables, milk, dairy products, ice cream, cold meat, beverages and other foods.

3, suitable for pharmaceutical logistics companies and refrigerated food logistics companies in the distribution of the use, such as: frozen fresh food, biological reagents, need to maintain low temperature or room temperature of the drugs.
