Problems solved by technology
[0003] However, after the general gas packaging bag is inflated, the bending area at the bottom usually cannot show a flat shape, and the problem of protruding outward due to the pressure of the gas is more common, which makes the bottom protrude after the general gas packaging bag is inflated. As for the inability to place the gas packaging bag on the table smoothly

Embodiment Construction
[0077] see figure 1 , figure 2 , image 3 and Figure 4 , which is a buffer air bag with a preset opening in the turning area of the air column disclosed in the present invention.
[0078] The buffer air bag with the preset opening in the turning area of the air column according to the embodiment of the present invention includes:
[0079] An air column sheet 200 is composed of a plurality of vertical heat sealing lines 21 and a plurality of transverse heat sealing lines 22 followed by two outer films 1a to form a plurality of air columns 1;
[0080] A plurality of turning points 4a, 4b are formed on the air columns 1 or the vertical heat-sealing lines 21 by heat-sealing the outer films 1a;
[0081] a turning center line M, located on the air column sheet 200, substantially parallel to the transverse heat sealing line 22;
[0082] A plurality of nodes 31a, 31b are located on both sides of the inflection center line M, and are spaced from the inflection center line M ...

The invention relates to a buffer air bag with an opening preset in an air column turning region and a method for manufacturing the buffer air bag. The buffer air bag comprises an air column sheet, turning points, a turning midline, nodes and side heat sealing lines. The air column sheet is composed of a plurality of air columns which are formed by connecting of a plurality of vertical heat sealing lines and a plurality of transverse heat sealing lines with two outer films; the turning points are formed by heat sealing connection of outer films and arranged on the air columns or the vertical heat sealing lines; the turning midline is disposed on the air column sheet; the nodes are arranged on two sides of the turning midline at preset intervals; and the side heat sealing lines are in heat sealing connection with two sides of the air column sheet after turning and extend from one end of the air column sheet to the nodes, and a turning non-heat-sealing section is formed between the nodes and the turning midline. When the air column sheet is inflated, a bottom is formed among the turning points, the non-heat-sealing section of the turning region forms an opening with a polygonal side, and a support face is formed at the bottom of the opening. The bottom of the buffer air bag is flat and free of sharp angles, so that the buffer air bag can abut against the table surface stably.
Description
technical field [0001] The invention relates to the technical field of object packaging, in particular to a buffer air bag with a preset opening in the turning area of an air column and a manufacturing method thereof. Background technique [0002] At present, when packaging items, most of them are covered with bubble wrap or styrofoam, but there are still problems such as poor buffering effect or environmental pollution. In order to solve the defects of bubble paper and styrofoam, a gas packaging bag has been developed, which is sealed by heat sealing to form an air column, and is provided with an inflation port for inflation. When the gas is inflated into the air column through the inflation port After that, the gas packaging bag can be used in the inner packaging as a buffer material. [0003] However, after the general gas packaging bag is inflated, the bent area at the bottom usually cannot show a flat shape, and the problem of outward protrusion naturally occurs due ...
