1. 3.Otsutsa / Polypropylene

Izi zikuwoneka bwino komanso zazikulu kwambiri pilo. Mikangano sikokwanira, zitha kunenedwa kuti palibe zovuta konse, ndipo kusindikiza ndikosavuta kungoganiza. Iyenera kuyikidwapo kwa nthawi mutasindikiza, kenako chikwamacho chimadulidwa.

1. 4. CPP / polypropylene / terminal tambasulira polypropylene

Izi zimawoneka bwino kwambiri, kuumitsidwa kwambiri kuposa kavi filimu, zomveka bwino, nthawi zambiri zimagwiritsidwa ntchito ngati filimu yazosakanikirana ndi mafilimu ena m'matumba, ndi kanema wabwino. CPP imakhalanso ndi zida zophikira zomwe zingagwiritsidwe ntchito kupanga matumba ophika.

1. 5. Pet / Polyethylene Terephthate

Izi zilinso ndiKukongola Kwabwino, Mphamvu ndi Udindondiyabwino kuposa polystyrene ndi pvc, osati yosavuta kuthyola, yosalala komanso yonyezimira. Ndi imodzi mwazinthu wamba zophatikizira.

1. 6. Pa / Nylon

Izi nthawi zambiri zimakhala ndi chikwama chophika / thumba lotentha limapanga zinthu zambiri, kulimba mtima, zofewa.

1. 7. Aluminium fol / al

Masochi a aluminium amapangidwa ndi oyera aluminity atatha nthawi zambiri zakulera. Ndiwochititsa kutentha kwambiri komanso chishango chopepuka. Mphamvu yabwino yamakina, kulemera kopepuka, yokhala ndi zolimba, mawonekedwe abwino, mawonekedwe abwino, olimba, ndipo amasungunuka. Zitsulo zotchinga, chotchinga cha mpweya, chotupa chazotsatira sichili bwino, pambuyo pophatikiza ndikosavuta kuwoneka ngati zigawo zosanjikiza.
