Māhele ʻia i ʻelua ʻano: Lepili pepa, Lepili Film.
 
1. Hoʻohana nui ʻia ka lepili pepa i nā huahana holoi wai a me nā huahana mālama pilikino kaulana; Hoʻohana nui ʻia nā mea kiʻiʻoniʻoni i nā huahana kemika i kēlā me kēia lā. I kēia manawa, ʻoi aku ka nui o nā huahana mālama pilikino kaulana a me nā huahana holoi wai wai i ka mākeke, no laila ua hoʻohana hou ʻia nā mea pepa e pili ana.
 

Hoʻohana pinepine ʻia ka lepili kiʻiʻoniʻoni PE, PP, PVC a me kekahi mau mea synthetic ʻē aʻe, ʻo nā mea kiʻiʻoniʻoni he keʻokeʻo keʻokeʻo, matte, transparent ʻekolu. No ka mea ʻaʻole maikaʻi loa ka paʻi ʻana o nā mea kiʻiʻoniʻoni lahilahi, mālama ʻia ia e ka mālama corona a i ʻole ka hoʻohui ʻana i ka uhi ma luna o kona ʻili e hoʻonui ai i kona hiki ke paʻi. I mea e pale aku ai i ka deformation a i ʻole ka haehae ʻana i kekahi mau mea kiʻiʻoniʻoni i ka paʻi ʻana a me ka hoʻopaʻa inoa ʻana, e kau ʻia kekahi o nā mea i ka unidirectional a biaxial stretching. No ka laʻana, hoʻohana nui ʻia ʻo BOPP ma hope o ka biaxial tension.
 
Wahi noi:
ʻO nā lepili no ka ʻoihana lāʻau lapaʻau, ʻoihana kūʻai, ʻoihana hoʻopihapiha, ʻoihana lāʻau lapaʻau, ʻoihana uila a me ka uila, ka inoa logistic a pēlā aku. ʻO kekahi mau kiʻi e like me lalo:
