ʻO ka kiʻiʻoniʻoni metala PET
Hoʻolauna Huahana:
Loaʻa i kēia kiʻiʻoniʻoni nā waiwai pale maikaʻi loa, ke kūpaʻa i ka puncture, ke kūpaʻa i ka wela, ke kūpaʻa i ka makū, a me ka ʻōlinolino metala ʻālohilohi, e hoʻonui ana i ka nani o ka ʻōpala.
Nā Hoʻohana Huahana:
Hoʻohana nui ʻia i loko o ka ʻōpala o nā candies, nā pastries, nā meaʻai puffed, a me nā lāʻau lapaʻau.
Nā kikoʻī:
- **Mānoanoa**: ʻO ka maʻamau he 12 μm, hiki ke hoʻopilikino ʻia e like me nā koi o ka mea kūʻai.
