Daim ntawv khob kas fess feem ntau yog ua los ntawm cov ntaub ntawv hauv qab no:
Ntawv los ntawm ntawv (cov khoom tseem ceeb):
Cov ntoo pulp: Cov khoom siv tseem ceeb rau cov ntawv paperboard, uas yog los ntawm cov ntoo fibers. Cov pulp raug ua tiav thiab tsim ua ib daim ntawv paperboard.
Daim ntawv rov ua dua tshiab: Feem ntau siv los ua kom cov ntawv ua los ntawm ntoo zoo rau ib puag ncig, txawm hais tias qhov zoo yuav txawv.
Txheej polyethylene (rau kev tiv thaiv dej):
Feem ntau cov khob kas fes ntawv muaj ib txheej yas polyethylene nyias nyias sab hauv (qee zaum ob qho tib si sab hauv thiab sab nraud) kom lawv tsis txhob ntub dej thiab tiv thaiv cov kua kom tsis txhob nkag mus rau hauv daim ntawv. Cov txheej no kuj ua kom lub khob tuav tau cov dej kub.
Kua cwj mem (rau kev luam ntawv):
Cov kua mem uas siv tau rau zaub mov yog siv rau kev sau hom lossis kev tsim qauv luam tawm rau sab nraud ntawm lub khob. Feem ntau cov no tsis muaj tshuaj lom thiab muaj kev nyab xeeb rau kev siv rau ntawm cov thawv zaub mov.
Cov tshuaj pleev xim (xaiv tau):
Qee zaum, cov khob yuav muaj me ntsis xim lossis xim kom muab xim rau lawv, txawm hais tias feem ntau cov qauv khob ntawvs yog dawb los yog dawb.
Lub hau (xaiv tau):
Cov hau feem ntau yog ua los ntawm cov yas (xws li polystyrene lossis polypropylene), thiab qee zaum, lawv yog ua los ntawm cov ntawv nrog cov yas txheej nyias kom ua rau lawv tsis ntub dej.
Cov kev xaiv zoo rau ib puag ncig:
Muaj ib txhia chaw tsim khoom siv PLA (polylactic acid), uas yog ib yam khoom siv uas lwj tau los ntawm pob kws los yog qab zib, es tsis txhob siv polyethylene ua txheej. Qhov no ua rau cov khob zoo rau ib puag ncig thiab yooj yim dua rau kev ua chiv.
