Chidule ndi momwe chitukuko cha mafakitale osungiramo ziwiya za chakudya chofulumira chimakhalira

Bokosi la chakudya chachangu la pulasitiki lotayidwa ndi mtundu wa ziwiya zomwe zimakonzedwa ndi utomoni kapena zinthu zina za thermoplastic pogwiritsa ntchito ukadaulo wopangira pulasitiki wotentha kwambiri. Ponena za zinthu zopangira, mabokosi a chakudya chachangu a pulasitiki otayidwa amagawidwa m'mabokosi a chakudya chachangu a PP (polypropylene), bokosi la chakudya chachangu la PS (Polystyrene) ndi bokosi la chakudya chachangu la EPS (expanded polystyrene). Poyerekeza ndi mitundu ina iwiri ya zinthu zopangira, bokosi la chakudya chachangu la PP lili ndi kukana kutentha kwambiri. Ndilo bokosi lokhalo la chakudya chachangu lomwe lingatenthedwe mu uvuni wa microwave. Chifukwa cha kukhazikika kwake kwa mankhwala komanso kukana dzimbiri, lingagwiritsidwe ntchito pafupifupi pazakudya ndi zakumwa zonse.

Makampani opanga mabokosi a chakudya chofulumira omwe amatayidwa nthawi imodzi ndi omwe amapereka zinthu zopangira monga PP, PE, EPS, ndipo midstream ndi omwe amapanga mitundu yosiyanasiyana ya mabokosi a chakudya chofulumira. Zinthu zomalizidwa zimagwiritsidwa ntchito kwambiri pamsika woperekera zakudya komanso msika wotumizira chakudya.

Pofika mu 2019, pankhani ya ndalama zogulitsira, China ndiye kampani yayikulu kwambiri padziko lonse lapansi yopanga mabokosi a chakudya cha pulasitiki chogwiritsidwa ntchito nthawi imodzi, zomwe zimapangitsa kuti pakhale pafupifupi 44.3% ya makampani opanga mabokosi a chakudya cha pulasitiki chogwiritsidwa ntchito nthawi imodzi padziko lonse lapansi. Mu 2019, ndalama zomwe zimagulitsidwa m'mabokosi a chakudya cha pulasitiki chogwiritsidwa ntchito nthawi imodzi ku China zinali 9.55 biliyoni yuan, zomwe kuchuluka kwa pachaka kuyambira 2014 mpaka 2019 kunali 22.0%.

Kuchokera pamalingaliro a momwe ndalama zogulitsira zimagwiritsidwira ntchito m'mabokosi a chakudya chofulumira omwe amatayidwa ku China kuyambira 2014 mpaka 2019, makampani ogulitsa mabokosi a chakudya chofulumira omwe amatayidwa ku China amadalira kwambiri malonda a mabokosi a chakudya chofulumira omwe amatayidwa ku China. Mu 2019, mabokosi a chakudya chamasana a PP anali 60.94% ya msika wa mabokosi a chakudya chofulumira omwe amatayidwa ku China.
