Marudzi ese emabhegi, mabhokisi, maseti nemaenvelopu akagadzirwa nepepa, aluminium foil, fiber, plastic film uye complexes dzawo zvinochinjika kurongedza. Kazhinji, mapurasitiki epepa ane ukobvu husingasviki 0.25mm anonzi mafirimu. Firimu repurasitiki rinoonekera, rinochinjika, rine simba remvura, simba rehunyoro uye remhepo, simba rakanaka remakanika, hunhu hwemakemikari hwakagadzikana, simba remafuta, nyore kudhinda zvinyorwa zvakanaka, bhegi rekuisa chisimbiso rinogona kupisa. Rinogona kusangana nezvinodiwa zvekurongedza zvezvinhu zvemarudzi ese, rinoshandiswa mukupakata zviri nyore kuchengeta, zviri nyore kuisa chikafu chiri nyore, zvinodiwa zvezuva nezuva, zvinhu zvepakeji diki zvesupamaketi zvinhu zvakanaka. Guangdong Danqing Printing Co., Ltd ine makore makumi matatu eruzivo mukugadzira kurongedza kunochinjika, kunyanya kugadzira pouch yemuromo, bhegi rezipi rinomira, firimu repurasitiki nezvimwewo; Inopa kudhinda kwakanaka, inogona kudhinda kusvika kumavara gumi nematatu.

Kudhinda mapurasitiki anochinjika kunobva papurasitiki kunoita basa guru mukudhinda mapurasitiki. Zvichienderana nehuwandu, kubvira muna 1980, mapurasitiki anodhinda mune dzimwe nyika dzakabudirira pasi rose anoita 32.5% ~ 44% yekudhinda kwese kwepurasitiki.

Kazhinji, nekuti firimu rimwe chete harina kunaka pakudzivirira mukati, saka mafirimu anopfuura maviri anoshandiswa kusanganisa firimu rakasanganiswa, kuti zvienderane nezvinodiwa zvekuchengetedza chikafu, tekinoroji yekurongedza isina utachiona. Kusarudzwa kwezvinhu zvekunze zvefirimu rakasanganiswa hakusi nyore kukwenya, kupfeka, kushanda zvakanaka kwemaziso, kushanda zvakanaka kwekudhinda kwezvinhu, zvakaita se: bepa, cellophane, tensile polypropylene, polyester, nezvimwewo; Bhokisi repakati ipolymer inodzivisa, senge: aruminiyamu foil, steamed aruminiyamu, polyvinyl diazene electric inner layer zvinhu zvinonyanya kusarudzwa zvisina chepfu, polyethylene isina kunaka uye mamwe maresin ethermoplastic.
