Ngokwezinto ezisetyenziselwa ukuveliswa kwefilimu ye-polyester kunye nokuhlelwa kwenkqubo yokuvelisa.

Ngokutsho kwezixhobo ezahlukeneyo kunye neenkqubo zokudweba ezisetyenziselwa ukuveliswa kwefilimu ye-polyester inokwahlulwa ibe ziindidi ezimbini ezilandelayo.

1. Umboniso bhanyabhanya we-Bidirectional we-Stretch Polyester (BOPET)

Ifilimu ye-BOPET ngokubanzi kukusetyenziswa kwemathiriyeli yokukhanya (ekwabizwa ngokuba yimathiriyeli enkulu yokukhanya, oko kukuthi, umxholo we-polyester chip titanium dioxide ye-0.1%, emva kokumisa, ukunyibilika, ukukhupha, ukuphosa kunye nokwelula okuthe tye kunye nokuthe tye kwefilimu yodidi oluphezulu. , isetyenziswa ngokubanzi).Ifilimu ye-BOPET ineempawu zamandla aphezulu, ukuqina okuhle, ukungafihli kunye neglosi ephezulu.Ayinavumba, ayinancasa, ayinambala, ayinatyhefu, amandla abalaseleyo kunye nokuqina;Amandla ayo anamandla ngamaxesha e-3 yefilimu ye-PC, ifilimu ye-nylon, amandla empembelelo yi-3 ukuya kwi-5 amaxesha efilimu ye-BOPP, inokumelana nokugqwesa okugqwesileyo, ukuchasana nokugoqa, ukuxhathisa i-pinhole kunye nokuchasana nokukrazula;I-shrinkage ye-thermal incinci kakhulu, kwi-120 ℃, kuphela i-1.25% iyancipha emva kwe-15min;Inepropathi elungileyo ye-antistatic, kulula ukuyicoca i-aluminization, kwaye inokufakwa kunye ne-PVDC ukuphucula ukutywinwa kwayo kobushushu, ipropathi yesithintelo kunye nokubambelela kokuprinta;I-BOPET ikwanayo ukumelana nobushushu, ukumelana nokupheka okugqwesileyo, ukumelana neqondo lomkhenkce eliphantsi, ukumelana neoyile elungileyo kunye nokuxhathisa imichiza.Ifilimu ye-BOPET ngaphezu kwe-nitrobenzene, i-chloroform, i-benzyl alcohol, iikhemikhali ezininzi azikwazi ukuyenza inyibilike.Nangona kunjalo, i-BOPET iya kuchithwa yi-alkali enamandla, kwaye kufuneka ihoywe ingqalelo xa usebenzisa.Ifilimu ye-BOPET inomfunxa ophantsi wamanzi, ukuxhathisa okulungileyo kwamanzi, kwaye ifanelekile ukupakisha ukutya okunomxholo ophezulu wamanzi.

2. Unidirectional Stretch Polyester Film (CPET)

Ifilimu ye-CPET ngokubanzi kukusetyenziswa kwe-semi-matting material (i-chips ze-polyester ekrwada zongeza i-titanium dioxide), emva kokumisa, ukunyibilika, ukukhupha, ukuphosa kunye nokwelula ubude befilimu, ibakala eliphantsi kunye nexabiso kwifilimu ye-polyester, esetyenziselwa ithebhulethi yamachiza. ukupakishwa.Ngenxa yokusetyenziswa okuncinci, abavelisi abancinci bemveliso ephantsi, bebalelwa malunga ne-5% yecandelo lefilimu ye-polyester, amashishini aseTshayina athengiswa ngaphantsi, ubukhulu obuqhelekileyo be-150μm.
