Printing: Aluminum foil back sealing bags can be printed in up to 12 colors, or they can be made transparent without printing, or in natural colors such as aluminum foil.

Bag making: Aluminum foil back sealing bags are usually made on the middle sealing bag making machine. 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 aluminum foil back sealing bags or side sealing organ bags.

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

Aluminum foil back sealing bags, like self standing bags, have a more suitable appearance for sales and display images. Aluminum foil back sealing bags can also be made to withstand drop, so they 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 aluminum foil back sealing bags are 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.

真空袋及高溫蒸煮袋也基本上都是三邊封形式，主要是考慮熱封強(qiáng)度、氣密性等原因。

三邊封袋子還可以做成各種高阻隔袋子，一般高阻隔都是用鋁箔作為阻隔層，但考慮到透明度及鋁箔易折斷，所以有時(shí)也會(huì)用氧 化鋁PET、氧化硅PET、K鍍層材料、EVOH材料等高阻隔但同時(shí)又是透明的材料來替代鋁箔，但這些材料一般采購(gòu)周期較長(zhǎng)，并且價(jià)格也比較貴。

三邊封袋子使用范圍較廣，可以用在食品、藥品、電子產(chǎn)品、農(nóng)藥、面膜等各個(gè)領(lǐng)域。

袋子可以自動(dòng)給袋式包裝機(jī)使用，也可以人工灌裝使用。
