Ni ubuhe buryo bwa Biaxically Orient Polypropylene Filime Yuzuye?

Biaxically yerekanwe polypropilene (BOPP) ni ubwoko bwa firime ipakira neza. Biaxically yerekanwe polypropilene overrap firime irambuye mumashini no guhinduranya. Ibi bivamo icyerekezo cyerekezo cyerekezo cyerekezo cyombi.

Ubu bwoko bwa firime yoroheje yo gupakira bwakozwe hakoreshejwe uburyo bwo gukora tubular. Igituba kimeze nk'igituba cyuzuye kandi gishyuha kugeza aho cyoroshya (ibi bitandukanye no gushonga) kandi birambuye hamwe n'imashini. Filime ireshya hagati ya 300% - 400%.

Ubundi, firime irashobora kandi kuramburwa n'inzira izwi nka firime ya tenter-frame. Hamwe nubu buhanga, polymers zisohorwa kumuzingo ukonje (bizwi kandi nkurupapuro rwibanze) hanyuma ugashushanya icyerekezo cyimashini. Gukora amahema yerekana amahema akoresha imirongo myinshi yo gukora iyi firime.

Inzira ya tenter-frame muri rusange irambura firime 4.5: 1 mu cyerekezo cyimashini na 8.0: 1 muburyo bwo guhinduranya. Ibyo bivuzwe, ibipimo birashobora guhinduka rwose.

Inzira ya tenter-frame irasanzwe kuruta tubular variant. Itanga firime nziza cyane, isobanutse. Icyerekezo cya Biaxial cyongera imbaraga kandi bikavamo gukomera gukomeye, gukorera mu mucyo, no kurwanya cyane amavuta namavuta.

Filime ya BOPP iragaragaza kandi imiterere ya barrière kumyuka na ogisijeni. Kurwanya ingaruka hamwe na flexcrack birwanya nibyiza cyane hamwe na BOPP na polypropilene shrink firime.

Biaxically yerekanwe na polypropilene firime ya firime ikoreshwa cyane mugupakira ibiryo. Barimo gusimbuza byihuse selofane kubisabwa harimo ibiryo bya snack hamwe nububiko bwitabi. Ibi ahanini biterwa numutungo wabo wo hejuru hamwe nigiciro gito.

Ibigo byinshi bihitamo gukoresha BOPP mu mwanya wa firime gakondo zigabanuka kuko zigaragaza imitungo yongerewe ubushobozi nubushobozi buruta ubwa firime zisanzwe zipakira.

Twabibutsa ko gufunga ubushyuhe bigoye kuri firime ya BOPP. Ariko, ibi birashobora koroha mugusiga firime nyuma yo gutunganyirizwa hamwe nibikoresho bifunga ubushyuhe cyangwa gufatanya na co-polymer mbere yo kuyitunganya. Ibi bizavamo firime nyinshi.
