Kev tuag yog qhov tseem ceeb ntawm biaxially oriented cam khwb cia ntawv, txiav txim siab ncaj qha rau nrum daim ntawv zoo thiab tuab tsis sib xws. Qhov no biaxially taw qhia cov ntawv tuag txais yuav lub tsho khuam khiab mis ntws channel tsim, thiab nruab nrog cov kws tshaj lij khoos phis tawj tsom xam software, Flow channel CFD tsom xam thiab ua kom zoo dua, kom tau txais cov dej zoo tshaj plaws. Kev qhib qhov kev hloov pauv tau txais kev thawb-rub yam tsis siv neeg tuag di ncauj hloov pauv ， los ntawm kev ntsuas qhov tuab ntawm qhov tuab ntawm cov ntaub ntawv kuaj pom los ntawm khoos phis tawj kev ua haujlwm tom qab tawm tswv yim rau qhov tshwj xeeb tuag di ncauj thermal nthuav dav tswj cov ntsia liaj qhov rooj, rau kev qhib ntawm lub di ncauj tuab tuab tsis siv neeg nplua-tuning, tswj tau zoo ntawm cov khoom lag luam. Qhov no tuag siv rau: BOPP, BOPS, BOPA, BOPET, BOPI cov khoom lag luam thiab lwm yam.

Cov di ncauj tuag ncaj, ntxhib thiab qhov loj ntawm daim di ncauj ntse yog qhov cuam tshuam ncaj qha rau cov khoom lag luam zoo. Tom qab
kev sim thiab rov ua qauv qhia, siv cov nthwv dej luv mem tes hauv lub zog kho kom zoo tuaj yeem txhim kho kev tuag zoo. yog li ntawd ua kom tawv tawv tawv, ua kom zoo dua microstructure, hnav tsis kam zoo dua li txheej txheem quenching. Tuag daim di ncauj ncaj thiab puas ua haujlwm kuj zoo dua.
