Embodiment Construction
[0092] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0093] figure 1 An example in which the reclosable self-standing packaging bag of the present invention is applied to a reclosable packaging bag is depicted. The self-standing reclosable bag 10 includes a main bag body 14 and a linear fastener 15 . The main bag body 14 is formed from 2 sheets of film material to form the opposite sides 11, 12 of the bag and a sheet 13 of film material forms the bottom of the bag. On the inner surface of the opening portion of the main packaging bag body 14, linear fasteners 15 are provided.
[0094] The above-mentioned main bag body 14 is made by folded film material 13 which is arranged between the lower parts of the respective sheets 11 , 12 of film material. So that the folded edge 13a of the film material 13 is directed upwards, the opposite edge portions of the film material sheets 11, 12 are heat-seal...

The present invention relates to a re-closable packaging bag and method for manufacturing same, the packaging bag includes: a mainly packaging bag body which has an opening part at above, and which is composed of a pair of relative folding sheets; A linearity fastening which is installed on the opening part on the mainly packing bag body, extending at horizontal direction, having prearranged length; and a sleeved element which is installed in the mainly packing bag under the plainness and cave-in state in generally, under the state, whole of the external surface of the sleeved element connecting with the inner surface of the mainly packing bag body, the sleeved element being not folded in the mainly packing bag body to make the sleeved element and the mainly packing bag body move between the common plainness cave-in state and the expansion state, the expansion state is limited by the sleeved element and the volume of the mainly packing bag body in the mainly packing bag body, while contacting between the outer surface of the sleeved element and the inner surface of the mainly packing bag body, the sleeved element being provided with the bottom of the basic opening at the state of expansion.
Description
[0001] This application is a divisional application of an application with a filing date of March 7, 2001 and a Chinese application number of 01117241.X. technical field [0002] The present invention relates to packaging bags which can be re-opened and reclosed, and to a method of making such reclosable packaging bags. Background technique [0003] Such as Figure 25 As shown, a commonly used reclosable packaging bag 1 includes a main packaging bag body 7 and a wire fastener 9 . The main packaging bag body 7 is formed by placing two sheets of plastic film material 2, 3, one on top of the other, heat sealing the opposite side and lower edges of the packaging bag body 7, so that the main The packaging bag body 7 has an upper opening portion 8 and sealing portions 4, 5, 6. On the inner surface of the opening portion 8 of the main bag body 7, a linear fastener 9 is provided. After filling the contents into the packaging bag 1, the opening edge of the reclosable packaging bag ...
