Kodi mawonekedwe a hollow blowing ndi chiyani?

Njira yopangira nkhonya yopanda kanthu imakhala ndi mawonekedwe a kuumba kosavuta, kupanga bwino kwambiri, mtengo wotsika wazinthu, komanso ntchito yosavuta.Zotengera zonyamula zimatha kupangidwa ndikuwumba kuchokera m'mabotolo oponya m'maso okhala ndi milliliters angapo mpaka zotengera zosungira ndi zonyamulira zokhala ndi malita masauzande angapo.Mapulasitiki omwe amagwiritsidwa ntchito popanga phokoso lopanda kanthu akuphatikizapo: polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyester ya thermoplastic, polyamide, cellulose acetate, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri ndi polyethylene.
