Air column bag for cold chain transportation

Abstract

The invention belongs to the technical field of air column bags and discloses an air column bag for cold chain transportation. The air column bag comprises an upper film used for making contact with foods, and a lower film forming an outer surface after wrapping foods. A plurality of vertical heat seals are arranged between the upper film and the lower film and separate the upper film and the lower film into a plurality of air columns. The two ends of the multiple air columns are connected through the upper heat seals and the lower heat seals correspondingly. The ends, close to the upper heatseals, in the air columns are each provided with an air valve film. The outer surface of the lower film is provided with an antiskid structure used for preventing water in air from coagulating into asmooth ice layer. The antiskid structure is arranged, thus when the air column bag is placed in a freezing chamber, the water in the air is prevented from coagulating into the smooth ice layer, the points of force during taking of the air column bag and the foods therein are increased, and grabbing and transportation are convenient.

Description

technical field [0001] The invention relates to the technical field of air column bags, more specifically, it relates to an air column bag for cold chain transportation. Background technique [0002] Air column bag, also known as cushioning air column bag and inflatable bag, is a new type of patented packaging material filled with natural air. It is currently the most economical and environmentally friendly cushioning packaging material. The air column bag utilizes a fully covered air column for buffer protection, disperses pressure, and minimizes the loss rate of product transportation. [0003] In the prior art, the air column bag is provided with an air valve film to automatically lock the air, which is simple and convenient. A kind of anti-shock cushioning air column bag proposed by the Chinese patent whose patent publication number is CN106315019A is made by bonding the first film and the second film to each other and hot pressing; the first film and the second film ar...

Problems solved by technology

[0005] In practical use, the air column bags are made of smooth plastic as the raw material. During cold chain transportation, a layer of smooth ice is easy to form on the surface of the air column bags. When taking the above air column bags, it is inconvenient for people to focus and grab For this problem, the purpose of the present invention is to propose an air column bag for cold chain transportation. The lower film is provided with a non-slip structure to prevent the moisture in the air from condensing into a smooth ice layer, thereby increasing the focus when taking the air column bag and the food in it. , easy to grab and transport, the specific plan is as follows:
