Tom qab ntawd, Yuyao Plastics General Factory thiab Yuyao Engineering Plastics Factory kuj tau pib koom nrog kev tsim cov khoom yas.

Xyoo 1970, cov tuam txhab yas uas Yuyao Second Light Industry Bureau tau pib tsim los ntawm ib lub tuam txhab tom qab ib lub. Thaum kawg ntawm xyoo 1991, muaj 708 lub tuam txhab tsim khoom yas thiab ua cov khoom lag luam, suav txog 4.5% ntawm tag nrho 15,864 lub tuam txhab tsim khoom hauv Yuyao. Tsis tas li ntawd, muaj ze li ntawm 1,000 tsev neeg nyob deb nroog uas koom nrog kev tsim khoom yas thiab ua cov khoom lag luam yas. Yuyao tau raug hu ua "Lub nroog ntawm cov yas" vim tias yuav luag muaj cov tuam txhab tsim khoom yas hauv cov zos thiab cov khoom lag luam yas ua cov khoom lag luam hauv txhua lub zos.
Nrog rau kev loj hlob ntawm cov lag luam yas hauv nroog thiab nyob deb nroog, ib pawg neeg muag khoom tshwj xeeb hauv kev lag luam ntawm cov khoom siv yas tau tshwm sim. Thaum ntxov xyoo 1980, lub tuam txhab Yuyao Chemical and Building Materials Company thiab lub khw muag khoom Yuyao Chengbei Material Scaling Store los ntawm Zhang Qingjian tau ua tus thawj coj hauv kev ua lag luam yas raw khoom ze ntawm Yuyao North Bus Station (tam sim no Shunquan Hotel) nrog kev thauj mus los yooj yim.

"Lub sijhawm ntawd, peb tau coj cov tuam txhab cuam tshuam mus rau thaj tsam North Automobile Station, yog li pab txhawb rau kev tsim lub chaw faib khoom yas thiab North Road tshiab "Plastic Street" uas ntev li ib mais." Shao Feng hais.
Vim yog qhov zoo, tus nqi qis, thiab ntau yam khoom tiav, cov tub lag luam los ntawm thoob plaws lub tebchaws tab tom tuaj.

Thaum pom zoo los tsim kom muaj Yuyao Plastics Market, lub tswv yim ntawm kev tsim China Plastics City yog nyob rau hauv cov txheej txheem. "Wenzhou muaj lub khw muag khawm, Shaoxing muaj lub khw muag ntaub, thiab Haining muaj lub nroog tawv. Peb txhua tus xav tias, Yuyao tuaj yeem muaj dab tsi?" Shao Feng hais tias, "China Plastics City tau tsim los ntawm kos hauv kev tshawb nrhiav."

Qhov laj thawj uas ua rau Yuyao Plastics txoj kev lag luam ua tiav yog vim peb muaj lub siab ncaj ncees thiab lub siab xav ua haujlwm nrog lwm tus. PebNingbo Prestige Hlau Khoom Co., Ltd.kuj tau kis tus kab mob los ntawm tiam neeg dhau los, thiab peb muaj tib lub hom phiaj qub thiab tsim ua ke. Peb cov khoom tseem ceeb yogpwm, cov diav yas, cov raj yas, thiab lwm yam,
