Ubumenyi bw'ibanze ku bijyanye na filime ya pulasitiki

Mu magambo y’igihugu agenga ipaki (GB4122-83), ibisobanuro by’ipaki yoroshye ni: ipaki yoroshye bivuga ipaki ishobora guhindura imiterere y’ikintu nyuma yo kuzuza cyangwa gukuramo ibirimo. Ubwoko bwose bw’amasakoshi, amasanduku, amapaki n’amabahasha bikozwe mu mpapuro, aluminiyumu, fibre, filime ya pulasitiki n’ibice byabyo ni ipaki yoroshye. Muri rusange, plastike ifite ubugari buri munsi ya 0.25mm yitwa filime. Filime ya pulasitiki irabonerana, yoroshye, ifite ubushobozi bwo kwirinda amazi, ifite ubushobozi bwo kwirinda ubushuhe n’umwuka, ifite imbaraga nziza za mekanike, ifite ubushobozi bwo kudahinduka, ifite ubushobozi bwo kudahinduka bw’amavuta, ifite uburyo bwo gucapa neza, ifite ubushobozi bwo gushyushya ipaki. Ishobora guhaza ibisabwa mu ipaki y’ibintu byose, ikoreshwa mu ipaki y’ibiryo byoroshye kubika, ifite uburyo bworoshye bwo gushyiramo ibiryo, ibikoresho bya buri munsi, ifite ibikoresho bito byo gupakira mu maduka. Guangdong Danqing Printing Co., Ltd ifite uburambe bw’imyaka 30 mu gukora ipaki yoroshye, ikora cyane cyane isakoshi y’umunwa, isakoshi ya zipu, filime ya pulasitiki n’ibindi; Itanga icapiro ryiza, ishobora gucapa amabara agera kuri 13.

Gucapa amapaki yoroshye hashingiwe kuri pulasitiki bigira uruhare runini mu gucapa amapaki. Dukurikije imibare, kuva mu 1980, amapaki ya pulasitiki mu bihugu bimwe na bimwe byateye imbere ku isi agize 32.5% ~ 44% by'amapaki yose acapwa.

Muri rusange, kubera ko ibikoresho bya firime imwe atari byiza mu kurinda imbere, bityo ubwoko burenze bubiri bwa firime zikoreshwa mu guhuza urwego rwa firime ivanze, kugira ngo huzuzwe ibisabwa mu kubungabunga ibiribwa, ikoranabuhanga ryo gupakira ridafite aside. Guhitamo ibikoresho byo hanze bya firime ivanze ntabwo byoroshye gukurura, kwangirika, imikorere myiza y'amatara, imikorere myiza yo gucapa ibikoresho, nko: impapuro, cellophane, polypropylene ifatana, polyester, nibindi; Urwego rwo hagati ni polimeri irinda, nko: foil ya aluminium, aluminiyumu ishyushye, polyvinyl diazene electrolyte imbere ibikoresho ahanini bitoranywamo bitari uburozi, polyethylene idafite uburyohe n'indi resin ya thermoplastic.
