Filimi yo gupfunyikaho ya Polypropylene ishingiye ku ruhande rumwe n'urundi ruhande ni iki?
Filimi ya polypropylene ishingiye ku murongo wa biaxial (BOPP) ni ubwoko bwa filime yo gupfunyika ikoresha uburyo bworoshye. Filimi yo gupfunyika ishingiye ku murongo wa biaxial iramburirwa mu mashini no mu cyerekezo cyo kuzenguruka. Ibi bituma habaho icyerekezo cy’uruhererekane rw’ibice byombi. Ubu bwoko bwa filime yo gupfunyika ikoreshwa mu buryo bworoshye ikorwa binyuze mu buryo bwo gukora umuyoboro. Umubyimba wa filime umeze nk'umuyoboro urashyuha ugashyuha kugeza aho woroshye (ibi bitandukanye n'aho ushongesha) kandi uramburirwa n'imashini. Filimi ishobora kandi kuramburirwa hakoreshejwe uburyo buzwi nka tenter-frame manufacturing. Hamwe n'ubu buryo, polimeri zishyirwa ku mugozi ukonje (uzwi kandi nk'urupapuro rw'ibanze) hanyuma zigakururwa mu cyerekezo cy'imashini. Tenter-frame filime idukorera... -
