Printing: The back sealing bag of the organ can be printed in up to 12 colors, or it can be made into transparent or natural colors such as aluminum foil without printing.

Bag making: Organ back sealing bags are usually made on the middle sealing bag making machine, and the main attention should be paid to the heat sealing fastness at the intersection of the four layers, which may cause air leakage due to poor sealing.

There are many cases of making organ back sealing bags or side sealing organ bags.

The bag making machine for organ back sealing bags is quite special, and the zipper is installed horizontally, which is different from the direction of bag making.

The drop resistant aluminum foil back sealing bag, like the self standing bag, has a more suitable appearance for sales and display images. The organ back sealing bag can also achieve good drop resistance, so it can be used to make 25kg particle bags or other heavy packaging. However, the overlap of the four layers of materials can easily cause air leakage due to poor sealing, so the back sealing bag of the organ is generally not used for vacuum pumping or liquid filling. If vacuum pumping or liquid filling is necessary, special attention should be paid to the overlap of the four layers of materials.

真空袋及高温蒸煮袋也基本上都是三边封形式，主要是考虑热封强度、气密性等原因。

三边封袋子还可以做成各种高阻隔袋子，一般高阻隔都是用铝箔作为阻隔层，但考虑到透明度及铝箔易折断，所以有时也会用氧 化铝PET、氧化硅PET、K镀层材料、EVOH材料等高阻隔但同时又是透明的材料来替代铝箔，但这些材料一般采购周期较长，并且价格也比较贵。

三边封袋子使用范围较广，可以用在食品、药品、电子产品、农药、面膜等各个领域。

袋子可以自动给袋式包装机使用，也可以人工灌装使用。
