Zithini iipolisi ezinxulumene nomzi-mveliso we-polypropylene ngo-2021? Xa sijonga emva kwindlela amaxabiso ahamba ngayo kunyaka, ukunyuka kwesiqingatha sokuqala sonyaka kwavela kwi-resonance ephindwe kabini yokunyuka kwe-oyile ekrwada kunye nemozulu ebanda kakhulu eMelika. NgoMatshi, kwangena igagasi lokuqala lokunyuka kwee-rebounds. Ifestile yokuthumela ngaphandle yavulwa kunye nale ndlela, kwaye ukunikezelwa kwempahla ekhaya kwakunqongophele. Kwanyuswa, kwaye ukubuyiselwa kwezinto zangaphandle okwalandelayo kwacinezela ukunyuka kwe-polypropylene, kwaye ukusebenza kwikota yesibini kwakuphakathi. Kwisiqingatha sesibini sonyaka, ulawulo oluphindwe kabini lokusetyenziswa kwamandla kunye nokwahlulwa kwamandla kuye kwabangela ukuba kubekho i-resonance eninzi.
