Yeyiphi imigaqo-nkqubo enxulumene neshishini lepolypropylene ngo-2021? Ukujonga emva kwindlela yexabiso enyakeni, ukunyuka kwisiqingatha sokuqala sonyaka kwavela kwi-resonance ephindwe kabini yokunyuka kweoli ekrwada kunye nemozulu ebanda kakhulu e-United States. Ngo-Matshi, i-wave yokuqala yokubuyisela i-rebounds yangeniswa. Ifestile yokuthumela ngaphandle yavula kunye nomkhwa, kwaye unikezelo lwangaphakathi lwalunqongophele. Ityhalwe phezulu, kwaye ukubuyiswa okulandelayo kofakelo lwangaphandle kwacinezela ukunyuka kwepolypropylene, kwaye ukusebenza kwikota yesibini bekuphakathi. Kwisiqingatha sesibini sonyaka, ulawulo olubini lokusetyenziswa kwamandla kunye nokulinganiselwa kwamandla
