Ibhande le-PP (ibhande le-polypropylene) lizuza amandla ayo ngenqubo yokukhiqiza ebizwa ngokuthi i-molecular orientation. Ngesikhathi sokukhiqiza, ibhande elikhishiwe linwetshwa ngaphansi kwezimo ezilawulwayo, kuqondanisa amaketanga e-polymer ngobude bebhande.

Ukupakishwa komkhakha osindayo kudinga ibhande elibamba ngaphansi kwengcindezi eqhubekayo, limelana nokuhuzuka, futhi likwazi ukulondoloza isitoreji sangaphandle nokuhamba olwandle. Ibhande le-PET (ibhande le-polyester) nentambo ye-polyester zombili zisetshenziselwa ukuvikela umthwalo, kodwa zisebenza ngendlela ehluke kakhulu. Intambo ye-polyester iyelula ngaphansi komthwalo, ilahlekelwa ukushuba lapho impahla izinza, futhi ihubeka ngokushesha emaphethelweni ensimbi acijile.

I-PP strapping (i-polypropylene strapping) itholakala ngobubanzi obujwayelekile ukusuka ku-5mm kuya ku-19mm, no-9mm, 12mm, 15mm, kanye no-19mm osayizi abavame ukugcwala. Ukukhetha ububanzi kunquma ukusatshalaliswa komthwalo, amandla ekhefu, nokuhambisana kwemishini. Izintambo ezincane (5–9mm) zihambisana namabhokisi alula kanye nokupakishwa kwe-e-commerce, kuyilapho izinketho ezibanzi (15–19mm) ziphatha amaphalethi asindayo nemithwalo yezimboni. Lo mhlahlandlela uchaza ububanzi obujwayelekile obutholakalayo be-PP strapping rolls, ukuthi ububanzi buthinta kanjani ukusebenza, nokuthi ungakhetha kanjani ukucaciswa okulungile kohlelo lwakho lokusebenza.

Ibhande le-PET (ibhande le-polyester) litholakala ngobukhulu obusukela ku-0.4mm kuya ku-1.25mm, ububanzi ngalunye bufanele izidingo ezithile zomthwalo kanye nezinhlobo zemishini. Amabhande azacile (0.4–0.55mm) anikezela ngemithwalo emincane yephalethi nokupakishwa okuvamile, kuyilapho izinketho eziwugqinsi (0.8–1.25mm) zibamba amakhoyili ensimbi, amabhala kakotini, kanye nezinhlelo zokusebenza ezidingeka kakhulu zezimboni.

Ibhande le-PP (ibhande le-polypropylene) litholakala ngogqinsi ukusuka ku-0.35mm kuya ku-0.80mm, futhi uhla ngalunye lufanele izidingo ezithile zomthwalo nezinhlobo zemishini. Izintambo ezincanyana (0.35-0.45mm) zinikeza amabhokisi alula kanye nokupakishwa kwe-e-commerce, kuyilapho izinketho eziwugqinsi (0.65-0.80mm) ziphatha amaphalethi asindayo nemithwalo yezimboni. Ubukhulu buthinta ngokuqondile amandla ekhefu, ukusebenza kophawu, nokuthembeka kokuphakelwa komshini. Lo mhlahlandlela uchaza izinketho ezijwayelekile zokujiya ezitholakalayo zebhande le-PP, ukuthi ukujiya kuhlobana kanjani nokunqamuka kwamandla, nokuthi ungakhetha kanjani ukucaciswa okulungile kohlelo lwakho lokusebenza.

Ubukhulu obuyisisekelo buphakathi kokucaciswa okunganakwa kakhulu lapho abathengi bekhetha ibhande le-PET (ibhande le-polyester) ukuze basebenze ngokuzenzakalelayo. Ibhande elihlangabezana nazo zonke izidingo zomshini—ububanzi obulungile, ukujiya, namandla okuphuka—lisazobangela izinkinga zokuphakela uma usayizi walo oyinhloko ungafani nesikhiphi sekhanda esibophayo. Idayamitha emaphakathi engaphakathi, ububanzi beroli, kanye nobubanzi be-roll yangaphandle kufanele konke kuhambisane ne-spindle yomshini kanye nendlela yokuqaqa. Lo mhlahlandlela uchaza ubukhulu be-PET strap core, ukuthi buthinta kanjani ukusebenza kwekhanda lokubopha okuzenzakalelayo, kanye nendlela yokuqinisekisa ukuhambisana ngaphambi kokuthenga.

Ukukhetha phakathi kwamabanga ahlanganisa i-PP kuthinta ukusebenza kwesikhathi eside kunalokho abathengi abaningi abakuqaphelayo. I-high-viscosity polypropylene strapping-ekhiqizwe kusuka ku-resin ene-viscosity yangaphakathi phakathi kuka-0.60 no-0.95 dl/g-inikeza ubude be-molecular chain, okuholela ekuqineni okuphezulu, ukumelana nokukhamba okungcono, nokugcinwa kokusebenza okuthuthukisiwe ngokuhamba kwesikhathi. Ibhande le-PP elisezingeni elijwayelekile lingase lisebenze ngokwanele ezinhlelweni zesikhashana noma ezilula kodwa lingalahlekelwa ukungezwani ngokushesha ngaphansi komthwalo oqhubekayo. Lesi sihloko siqhathanisa womabili amamaki esakhiwo samangqamuzana, izakhiwo zemishini, nokusebenza kwesikhathi eside ukusiza abathengi bakhethe ukucaciswa okulungile.

Ukukhetha phakathi kwebhande le-PET (ibhande le-polyester) kanye nebhande lensimbi kungenye yezinqumo ezibaluleke kakhulu ekufakweni kwezimboni. Ibhande le-PET linikeza ukonga izindleko ezingafika ku-50% ngonyawo ngalunye, liqeda izingozi zokulimala emiphethweni ebukhali kanye ne-snap-back, futhi linikeza ukugcinwa kwengcindezi ephakeme njengoba imithwalo ithula ngesikhathi sokuthutha. Izintambo zensimbi ziletha ukuqina okukhulu kwemithwalo enzima kakhulu kodwa ithwala izindleko ezifihliwe ezihlanganisa nezidingo eziphezulu zabasebenzi, ubungozi bokugqwala, kanye nokugqokwa kwemishini. Ngokwemininingwane yemboni, ibhande le-PET lihlinzeka ngokuphindwe kane komugqa ngethani ngalinye uma liqhathaniswa nensimbi, lishintsha ngokuyisisekelo isibalo sezindleko.

I-PP strapping (i-polypropylene strapping) yinto esetshenziswa kakhulu yokubopha ama-packaging aphakathi nendawo. Yenziwe nge-polypropylene resin ngokusebenzisa izinqubo zokukhipha kanye nokwelula, ukubopha kwe-PP kuhlanganisa ukuguquguquka, ukuphumelela kwezindleko, kanye nokusebenziseka kalula. Ngokusho kuka-Signode, umkhiqizi ohamba phambili wokubopha izintambo, izintambo ze-PP zenzelwe ukuhlanganisa, ukuhlanganisa, ukuhlanganisa, ukuvalwa kwebhokisi nokuqinisa.

I-PET strap (i-polyester strap) itholakala ngobubanzi obujwayelekile obusuka ku-9mm kuya ku-32mm, enobukhulu obuvamile obuhlanganisa i-12mm, 16mm, 19mm, 25mm, ne-32mm. Ukukhetha ububanzi kuthinta ngokuqondile amandla ekhefu, ukusatshalaliswa komthwalo, nokuhambisana kwemishini. Ibhande le-PET elingu-19mm livamise ukuletha amandla okuphuka angu-450–550kg, kanti ibhande elingu-25mm lingadlula u-900kg—ukusondela ekusebenzeni kwebhande lensimbi ngesisindo esiphansi kakhulu nezindleko.
