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(lái)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。
