Chikwama chavavu cham'munsi chokhala ndi doko la valve chimapanga thupi lalikulu mutadzaza, makamaka yosavuta kuyimirira ndikuyika.Mbali za thumba zimatha kusindikizidwa, kupereka malo okwanira kuti alengeze zambiri za mankhwala.Chikwama cha valve pansi chili ndi njira yapadera yotulutsa mpweya: kachipangizo kakang'ono kwambiri kapena kachipangizo ka labyrinth, choyenera kudzaza zinthu za ufa.Pali mawonekedwe ambiri a doko la valve (doko la valavu yam'mphepete, khomo la valve yowonjezera, khomo la valve, etc.).

Chikwama cha valve pansi pamunsi chikhoza kupangidwa ndi ma gramu osiyanasiyana a pulasitiki kapena filimu yophatikizika, yodzaza pakamwa pa valve, pakamwa pa valve imatha kusindikizidwa yokha mutadzaza, kupewa kudzaza.

Mankhwala gulu

Matumba a valve amatha kugawidwa m'matumba a PP valve, matumba a valve a PE, matumba a valavu opangidwa ndi mapepala apulasitiki, matumba a vavu a kraft ndi matumba a valve a kraft.PP vavu mthumba amapangidwa polypropylene nsalu nsalu, General PP nsalu thumba akhoza kusintha ma CD Mwachangu;PE valavu thumba lapangidwa polyethylene nsalu nsalu;Phukusi la valavu lopangidwa ndi mapepala apulasitiki limapangidwa ndi thumba la pulasitiki loluka ndi pepala;Kraft valve pocket zakuthupi zimapangidwa makamaka ndi pepala la kraft, lomwe limagawidwa m'mapepala a kraft otumizidwa kunja ndi mapepala apakhomo.

Thumba la valavu likhozanso kugawidwa mu: thumba lapamwamba lotsegula la valve, thumba lotsegula la valve, thumba lapamwamba ndi lotsika lotsegula la valve.

Kugwiritsa ntchito pocket ya valve

Mthumba valavu zimagwiritsa ntchito kulongedza chakudya ufa, ufa mankhwala, feteleza mankhwala, zipangizo kupanga, chakudya, mchere, mchere ndi zina powdery kapena granular olimba zinthu ndi zosintha.Makamaka oyenera mabizinesi kunja ntchito, akhoza kusintha ma CD kalasi ya mankhwala.

BC ma CD oyamba: Mu 2006, WenZhou Bai Chuan Pulasitiki Makampani ochepa kampani anakhazikitsa, kulembetsa likulu mamiliyoni asanu, msonkhano 3000 lalikulu mita, kampani kale anayamba kulembetsa likulu kuchuluka kwa 32 miliyoni tsopano, latsopano msonkhano kumanga dera anawonjezera kwa 20000 lalikulu mita. .Kupanga ndi kuchuluka kwa bizinesi kumaphatikizapo: thumba la pulasitiki loluka, thumba la pulasitiki la pepala, thumba la valve, ndi zina.
