Air column bag and air way for buffer air column

Abstract

The invention discloses an air way for a buffer air column. The air way comprises a first air way and multiple second air ways. The first air way is used for allowing external air to be inflated in and transversely flow. The second air ways communicate with the first air way and are used for allowing the air to flow to an air storage chamber to form the air column. Any second air way comprises anair guide passageway and an air guide opening for allowing the air in the first air way to flow to the air guide passageway, wherein the air guide opening and the air guide passageway can adjust the speed and the pressure of airflow in order to avoid air leakage. The invention further discloses an air column bag with the air way for the buffer air column. By means of the air way for the buffer aircolumn, the air retaining time can be greatly prolonged, the air inflow speed and the reflux speed of the air in the air column can be reduced, impact force of the air for an external film is reduced, thus, the quality of products can be more reliable, and the air closing effect is better.

Description

technical field [0001] The invention relates to the technical field of packaging and transportation, in particular to an air channel for a buffer air column. The present invention also relates to an air column bag having the air channel for buffering the air column. Background technique [0002] Air column bag, also known as buffer air column bag, is a new type of shockproof packaging filled with natural air. Compared with traditional foam cushioning packaging, air column bags have excellent characteristics such as recyclability, low cost, high protection, and space saving, so they are widely used in product transportation packaging. [0003] The air channel of the air column determines the flow direction and velocity of the gas. At present, the main function of the air channel is to allow the gas to flow in a certain direction to form an air column. The air passages in the prior art are mainly formed by multiple transverse heat-sealing lines, multiple longitudinal heat-se...

AI Technical Summary

Problems solved by technology

The air passages in the prior art are mainly formed by multiple transverse heat-sealing lines, multiple longitudinal heat-sealing lines and heat-sealing patterns. The air passages are one of the key factors affecting the formation of the air column. However, the traditional heat-sealing patterns have There are many kinds of eight-shaped, smiling face, etc., but these patterns have the disadvantages of simple structure and insufficient connection strength, which will easily lead to gas scurrying, uneven flow rate, too large gas flow range, gas damage to the film, poor gas retention effect and backflow Defects such as high rate

[0004] Therefore, how to avoid the large gas flow range and poor gas retention effect caused by the air channel of the traditional air column bag is a technical problem that those skilled in the art need to solve at present.
