Blow molding insulated boxes, also known as hollow blow molding, is a rapidly developing plastic processing technology. This process is mainly used in a variety of plastic materials such as polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The hollow containers produced are often used for industrial packaging. The blow molding process includes two basic methods: extrusion blow molding and injection blow molding. In recent years, new technologies such as multi-layer blow molding and stretch blow molding have also emerged.

History

With the development of social economy and the progress of the medical and catering industries, blow molding insulated boxes have gradually become an important tool for medical transportation and takeaway delivery. In developed areas abroad, this product is already quite common; in China, its use is also becoming increasingly popular. In the early takeaway industry, a wide variety of insulation equipment was used, such as metal cabinets, foam boxes, etc., which were not only large in size and inconvenient to carry, but also had poor hygiene conditions. It was not until 1998 that a company in Beijing, China successfully developed and promoted a new type of insulated box, making this product popular nationwide in a short period of time, especially in Beijing, and has become a standard in the field of cold chain logistics.

Features

1. Heat and cold resistance: It can withstand high and low temperature environments, will not deform even in hot water, and is suitable for boiling water disinfection.

2. Durability: It has excellent impact resistance and firmness, can withstand heavy pressure and collision without breaking, and is not easy to scratch on the surface, with a long service life.

3. Sealing: Good sealing performance is one of the key characteristics of the incubator. Different brands may use different sealing methods, but they are all to ensure the long-term preservation of the food inside.

4. Fresh-keeping ability: Internationally, the fresh-keeping effect of the incubator is usually evaluated through moisture permeability tests. High-quality products perform well in this indicator and can significantly extend the freshness of food.

5. Versatility: Incubators of different specifications can be designed according to actual needs, and can be used with reusable high-tech ice packs. The ice packs can be used for both refrigeration and heating, and the size is flexible and adjustable.

6. Environmental protection: Made of food-grade environmentally friendly material LLDPE, it is non-toxic and odorless, can resist ultraviolet radiation, and is not easy to fade.

7. Easy to clean.

Classification

According to different usage scenarios and needs, blow-molded insulation boxes can be divided into many types, the most common of which include vehicle-mounted, shoulder-back and portable.
