PP strap (polypropylene strap) yi kumeka hi vukulu kusuka eka 0.35mm kuya eka 0.80mm, laha range yin’wana na yin’wana yifaneleke swilaveko swokarhi swa ndzhwalo na tinxaka ta switirhisiwa. Ti straps to olova (0.35–0.45mm) ti tirhela mabokisi yo vevuka na ku pakiwa ka e-commerce, kasi tindlela to tiya (0.65–0.80mm) ti khoma ti pallets to tika na ndzhwalo wa ti indasitiri. Ku enta swi khumba hiku kongoma matimba yo tshoveka, matirhelo ya seal, xikan’we naku tshembheka ka ku phamela ka muchini. Nkongomiso lowu wu hlamusela tindlela ta standard thickness leti kumekaka eka PP strap, ndlela leyi ku enta ku fambelanaka ha yona na matimba yo tshoveka, na ndlela yo hlawula specification leyi faneleke eka xitirhisiwa xa wena.

Ti dimensions ta core ti le xikarhi ka swihlawulekisi leswi honisiwaka ngopfu loko vaxavi va hlawula PET strap (polyester strap) eka matirhelo ya automatic strap. Xirhendzevutani lexi fikelelaka swilaveko hinkwaswo swa michini—ku anama lokunene, ku enta ni matimba yo tshoveka—xa ha ta vanga swiphiqo swa ku dya loko mpimo wa xona wa le ndzeni wu nga fambisani ni xitirhisiwa xo nyika nhloko ya xirhendzevutani. Core inner diameter, roll width, na roll outside diameter hinkwaswo swifanele ku fambisana na spindle ya muchini na unwinding mechanism. Nkongomiso lowu wu hlamusela swipimelo swa nkoka swa PET strap, ndlela leyi swi khumbaka matirhelo ya nhloko ya strapping ya otomatiki, na ndlela yo tiyisisa ku fambisana loko u nga si xava.

Ku hlawula exikarhi ka tigiredi ta PP strapping swi khumba matirhelo ya nkarhi wo leha ku tlula leswi vaxavi vo tala va swi lemukaka. High-viscosity polypropylene strapping—leyi humelerisiwaka kusuka eka resin leyingana intrinsic viscosity exikarhi ka 0.60 na 0.95 dl/g—yinyika ku leha ka molecular chain yale henhla, leswi endlaka leswaku kuva na matimba yale henhla ya tensile, creep resistance yo antswa, xikan’we naku antswisiwa ka performance retention hiku famba ka nkarhi. Standard-grade PP strapping yinga tirha kahle eka switirhisiwa swa nkarhi wo koma kumbe swo olova kambe yinga lahlekeriwa hi tension hiku hatlisa ehansi ka ndzhwalo lowu nga heriki. Xihloko lexi xi pimanisa tigiredi leti hatimbirhi eka xivumbeko xa molekhuli, swivumbeko swa michini, na matirhelo ya nkarhi wo leha ku pfuna vaxavi ku hlawula nxaxamelo lowu faneleke.

Ku hlawula exikarhi ka PET strap (polyester strap) na steel strapping i xin’wana xa swiboho leswinga na mbuyelo swinene eka ku pakiwa ka ti indasitiri. PET strap yinyika kufika eka 50% wa ku hlayisiwa ka ntsengo hi foot, yi herisa makhombo ya kuvaviseka kusuka eka matlhelo yo kariha na snap-back, naswona yinyika ku khomiwa ka tension yale henhla loko ndzhwalo wu tshamiseka hi nkarhi wa ku hundzisela. Ku bohiwa ka nsimbi swi tisa ku tiya lokukulu eka ndzhwalo lowukulu kambe swi rhwala swibalo leswi fihliweke ku katsa na swilaveko swa le henhla swa vatirhi, makhombo ya ku thyakisa rust, na ku onhaka ka switirhisiwa. Kuya hi data ya indasitiri, PET strap yinyika linear footage leyi phindhiweke ka mune hi thani loko ku pimanyisiwa na nsimbi, leswi cincaka hi xisekelo xiringaniso xa ntsengo.

PP strapping (polypropylene strapping) i switirhisiwa swo strapping leswi tirhisiwaka ngopfu eka switirhisiwa swo olova kuya eka swa le xikarhi swa ku paka. Yi endliwe kusuka eka polypropylene resin hiku tirhisa maendlelo ya extrusion na stretching, PP strapping yihlanganisa ku cinca cinca, ku durha ka mali, xikan’we naku olova ka kutirhisiwa. Kuya hi Signode, muendli wa swirhangiso loyi a rhangelaka, PP strapping yi endleriwe ku palletizing, unitizing, bundling, ku pfala ti carton xikan’we naku tiyisisa

PET strap (polyester strap) yi kumeka hi standard widths kusuka eka 9mm kuya eka 32mm, na vukulu lebyi tolovelekeke kukatsa na 12mm, 16mm, 19mm, 25mm, na 32mm. Ku hlawuriwa ka ku anama swi khumba hi ku kongoma matimba yo tshoveka, ku hangalasiwa ka ndzhwalo, na ku fambisana ka switirhisiwa. 19mm PET strap hi ntolovelo yi tisa matimba yo tshoveka ya 450–550kg, kasi 25mm strap yinga tlula 900kg—yi tshinelela matirhelo ya steel strapping hi ntiko wale hansi swinene na ntsengo.

PP strap (polypropylene strap) yi kumeka hi ku anama ka ntolovelo kusuka eka 5mm kuya eka 19mm, laha kungana vukulu lebyi tolovelekeke kukatsa na 5mm, 9mm, 12mm, 15mm, na 19mm. Ku hlawuriwa ka ku anama swi khumba hi ku kongoma ku hangalasiwa ka ndzhwalo, matimba yo tshoveka, na ku fambisana ka switirhisiwa. Nkongomiso lowu wu hlamusela swihlawulekisi swa ku anama swa ntolovelo leswi kumekaka, ndlela yo hlawula ku anama loku faneleke eka xitirhisiwa xa wena, na switandzhaku swa matirhelo ya sayizi yin’wana na yin’wana. Swipimelo swa indasitiri swikombisa leswaku ku anama swiboha matirhelo ya strap eka tindzhawu tinharhu ta nkoka: ku hangalasiwa ka ndzhwalo eka swiphemu swa phasela, matimba yo tshoveka na vuswikoti bya ndzhwalo, na ku fambisana ka chute ya switirhisiwa.

PET strap (polyester strap) na PP strap (polypropylene strap) i switirhisiwa swimbirhi leswi tolovelekeke swinene swo hlanganisa plastiki, hambiswiritano swi tirhela swikongomelo swo hambana hi xisekelo. Loko PP strap yinyika ku cinca cinca xikan’we naku hunguta ntsengo eka ku paka ka ntirho wo olova, PET strap yi tisa matimba yofana na nsimbi hiku leha ka le hansi, leswi endlaka leswaku yiva kahle eka ndzhwalo wo tika, vuhlayiselo byale handle, na ku rhumeriwa ka mpfhuka woleha. Nkongomiso lowu wu hlamusela leswaku PET strap i yini, ndlela leyi yi hambanaka ha yona na PP strap eka swivumbeko swa swilo na matirhelo, na ndlela yo hlawula ndlela leyinene eka xitirhisiwa xa wena xo karhi.

PP strap (polypropylene strap) i xitirhisiwa xo strapping lexi tirhisiwaka ngopfu eka switirhisiwa swo paka swo olova kuya eka swa le xikarhi emisaveni hinkwayo. Xihloko lexi xi hlamula swivutiso swimbirhi swa xisekelo: kahle-kahle PP strap i yini, naswona yi tirhisiwa yini? Hi hlamusela ndlela leyi PP strap yi endliwaka ha yona—kusuka eka polypropylene resin extrusion kuya eka molecular orientation leyi tisaka matimba na ku cinca cinca—naswona hi lavisisa matirhiselo ya yona yosungula eka ku tsemakanya palletizing, bundling, carton closure, na ku hetiseka ka e-commerce. Hi swihlawulekisi swa ku anama kusuka eka 5mm kuya eka 19mm, ku enta kusuka eka 0.35mm kuya eka 0.8mm, na matimba yo tshoveka kusuka eka 45kg kuya eka 230kg, PP strap yi pfumelelana na swilaveko swohambana hambana swa ku paka loko yirikarhi yinyika matirhelo lawa yanga durhiki .

Ku tiyisisa khwalithi ya PET strap (polyester strap) loko yinga se amukeriwa swi sivela ku tsandzeka ka ndzhwalo lowu durhaka xikan’we naku kavanyeteka ka matirhelo. Nkongomiso lowu wu katsa magoza ya nkoka yo tiyisisa ku katsa na ku kamberiwa ka matimba yo tshoveka, ku pima ku pakanisa ka tidimenxini, ku kamberiwa ka le henhla, na ku kamberiwa ka matsalwa. Hikuya hi swihlawulekisi swa ASTM D3950, ku tiyisisiwa ka khwalithi swifanele ku tiyisisa matimba ya tensile, elongation, na dimensional tolerances . Ku landzelela endlelo ro tiyisisa leri hlelekeke swi pfuna vatshila va ku xava ku tiyisisa leswaku bandi leri amukeriweke ri fikelela swilaveko leswi boxiweke.
