Iyi tepi inodzivirira kupisa inogadzirwa kubva kuPET (Polyethylene terephthalate) firimu rine yakakwirira tembiricha inodzivirira silicone adhesive.Yakanakira kuti mabhachi ako asabva panzvimbo dzekusangana, shinda, kana kupi zvako kwausingade kupfeka. Iyi tepi ndiyo chiyero cheindasitiri chepoda, e-coating, plating, pendi uye anodizing.Acid uye alkali kuramba, corrosion resistance, high pressure resistance, hapana glue rasara.Iko hakuna yakasara glue mushure mekugadzirwa.Mabhodhi edunhu akadhindwa, zvikamu zvemagetsi, resistors uye capacitors zvinogadziriswa panguva yekugadzira maitiro;midziyo yemumba, michina, zvemagetsi uye mamwe maindasitiri zvinoda yakakwirira-tembiricha pfapfaidzo pendi dziviriro uye yakakwirira-tembiricha adhesive fixation.
