I-AD*Isikhwama senkanyezi sisho isikhwama esincane esilukiwe se-polypropylene esigcwaliswa kusetshenziswa ivalvu.Futhi zivame ukubizwa ngokuthi izikhwama ze-valve ezingaphansi kwe-block noma izikhwama ze-valve ezilukiweyo ze-PP noma izikhwama ze-valve ezingezansi eziyisikwele.Asebenza ngokufana nesikhwama sevalve enamaphepha amaningi;noma kunjalo, kusetshenziswa ungqimba olulodwa kuphela lwento, futhi akukho okunamathelayo okudingekayo ukuze uvale isikhwama.Izikhwama ze-AD *Star nazo zingakhiqizwa ngephepha noma izendlalelo ze-PE uma kudingeka.Kubalulekile ukuqaphela ngenkathi kunezinto ezimbalwa ezithatha indawo lapho, izikhwama ze-AD*Star zithathwa kabanzi njengesikhwama se-valve esilukiwe esisezingeni eliphezulu esitholakala emakethe.

Izikhwama ze-AD*Star zingaphrintwa kusetshenziswa uyinki ojwayelekile(isibonelo, sisebenzisa uyinki wamanzi) kanye nokuphrinta kwesitayela sokucindezela noma sifakwe i-BOPP (Biaxially-Oriented Polypropylene) ukuphrinta kwekhwalithi yesithombe.noma Ifakwe ifilimu ye-matte ukuze iphrinte.

Nazi isibonelo sezikhwama zokumboza ifilimu ye-matte:
