Filime za PP ni iki?

IMITUNGO

Polypropylene cyangwa PP ni thermoplastic ihendutse kandi isobanutse neza, irabagirana cyane kandi ifite imbaraga zo gukurura. Ifite aho ishongesha cyane kurusha PE, bituma ikoreshwa mu buryo busaba koroshya ubushyuhe mu gihe cy'ubushyuhe bwinshi. Ifite kandi imiterere mike y'ubushyuhe n'urumuri rwinshi. Muri rusange, ubushobozi bwa PP bwo kuziba ubushyuhe ntabwo ari bwiza nk'ubwa LDPE. LDPE kandi ifite imbaraga zo gushwanyagurika neza no kudakora neza mu bushyuhe.

PP ishobora guhindurwamo icyuma, bigatuma habaho imiterere myiza y’imyobo irinda gazi mu buryo busaba imbaraga nyinshi aho igihe kirekire cyo kubika ibicuruzwa ari ngombwa.Filime za PPzikwiriye cyane mu bikorwa bitandukanye by’inganda, abaguzi, n’imodoka.

PP ishobora kongera gukoreshwa neza kandi ishobora kongera gukoreshwa mu bindi bicuruzwa byinshi bitandukanye. Ariko, bitandukanye n'impapuro n'ibindi bicuruzwa bya selulose, PP ntabwo ibora. Ku rundi ruhande, imyanda ya PP ntitanga ibintu birimo uburozi cyangwa byangiza.

Ubwoko bubiri bw'ingenzi ni polypropylene idakoresha icyuma (CPP) na polypropylene ikoresha icyuma gifata impande zombi (BOPP). Ubwo bwoko bwombi bufite urumuri rwinshi, urumuri rudasanzwe, ubushobozi bwiza cyangwa bwiza bwo kuziba ubushyuhe, ubushobozi bwo kurwanya ubushyuhe kurusha PE, hamwe n'ubushobozi bwiza bwo kubuza ubushuhe.

Filimi za Polypropylene (CPP)

Polypropylene idakoresha icyuma (CPP) muri rusange ibonekamo ibintu bike ugereranyije na polypropylene ikoresha icyuma kimwe (BOPP). Ariko, CPP yakomeje kuzamuka nk'amahitamo meza mu buryo busanzwe bwo gupakira ndetse no mu buryo budakoresha icyuma kimwe. Imiterere ya filime ishobora guhindurwa kugira ngo ihuze n'ibisabwa mu gupakira, imikorere, no gutunganya. Muri rusange, CPP ifite ubushobozi bwo kurwanya gucika no kwangirika, ubushyuhe bukonje kandi irinda ubushyuhe kurusha BOPP.

Filimi za Polypropylene zishingiye ku ruhande rumwe (BOPP)

Polypropylene cyangwa BOPP1 ifite umurongo wa kabiri w’imyanya ni yo filime y’ingenzi cyane ya polypropylene. Ni ubundi buryo bwiza bwo gusimbura cellophane, impapuro zasizweho irangi, na aluminiyumu. Icyerekezo cyongera imbaraga zo gukurura no gukomera, igabanya uburebure (bugoye kurambura), kandi ikongera imiterere y’urumuri, kandi ikongera imiterere y’imyuka. Muri rusange, BOPP ifite imbaraga zo gukurura, gukomera cyane (gukomera), uburebure buke, imbogamizi nziza ya gaze, n’ibihu bito kurusha CPP.

IBISABWA

Filimi ya PP ikoreshwa mu bikorwa byinshi bikunze gupfunyikamo nk'itabi, bombo, utuntu two kurya n'udupfunyika tw'ibiryo. Ishobora kandi gukoreshwa mu gupfunyika, udupfunyika twa kaseti, udupira two kwambara imyenda n'udupfunyika twanduye bikoreshwa mu buvuzi. Kubera ko PP ifite ubushobozi bwo kubuza umwuka gusa, akenshi iterwa n'izindi polymer nka PVDC cyangwa acrylic bituma irushaho kunoza ubushobozi bwayo bwo kubuza umwuka.

Bitewe n’impumuro nkeya, ubushobozi bwo kurwanya imiti myinshi no kudakora neza, ubwoko bwinshi bwa PP bukwiriye gukoreshwa mu gupfunyika hakurikijwe amabwiriza ya FDA.
