Chii chinonzi PET Strap uye Chii Chinoita Kuti Isiyane nePP Strap?

The Strapping Dilemma

Famba nemunzvimbo ipi neipi yekuchengetera zvinhu kana nzvimbo yekugovera, uye uchaona machira epurasitiki achichengetedza zvese kubva kumakatoni akareruka kusvika kune inorema simbi coils. Asi kwete ese mabhandi epurasitiki akafanana. Zvinhu zviviri zvinonyanya kuzivikanwa -PET strap (polyester) uye PP strap (polypropylene) -inotarisa zvakafanana asi inoita zvakasiyana zvikuru. Kusarudza zvinhu zvisiri izvo zvinogona kutungamirira kukutadza kwekutakura, zvinhu zvakakuvadzwa, uye mari isingakoshi.

Sekureva kwaSignode, inotungamira kugadzira tambo, sarudzo pakati pePET nePP inoenderana nehuremu hwemutoro, mamiriro ekunze, uye kureba kwekutumira. Kunzwisisa mutsauko kwakakosha pakurongedza nyanzvi kuita sarudzo dzine ruzivo rwekutenga.

PaJushuo Packaging , data redu rekugadzira rinoratidza kuti kududzira kusawirirana pakati pemhando yezvinhu uye zvinodiwa zvemashandisirwo ndezvimwe zvezvikonzero zvinowanzoitika zvekusashanda zvakanaka kwetambo kunotaurwa nevatengi.

1. Chii chinonzi PET Strap?

1.1 Tsanangudzo uye Kuumbwa Kwezvinhu

PET tambo (polyethylene terephthalate strap, inozivikanwawo sepolyester strap) ndeyepamusoro-simba rekusunga zvinhu zvakagadzirwa kubva ku polyethylene terephthalate resin. Inowanzo kunzi 'simbi yepurasitiki' tambo nekuda kwekusimba kwayo-ku-huremu reshiyo, iyo inoswedera kune iyo yesimbi ichiramba ichireruka uye yakachengeteka kubata.

Maitiro ekugadzira anosanganisira extrusion, biaxial kutambanudza, uye kupisa kuseta kuti uwane mamolecular orientation iyo inowedzera simba rekusimba. Yepamusoro-inoshanda PET tambo inogona kuwana kusimba kwekusimba kwe200–300 MPa, yakanyanya kukwirisa kupfuura PP strap's 100–150 MPa renji.

1.2 Maitiro Akakosha Ekuita

PET tambo inopa akati wandei akasiyana maitiro ekuita:

• Simbi-yakafanana nekusimba simba : 200-300 MPa, inogonesa basa rinorema-basa

• Low elongation : Kazhinji 10-18% panguva yekuzorora, kuchengetedza kusawirirana nekufamba kwenguva

• Superior tension retention : Kuzorora kudiki, kunyangwe mitoro inogadzika kana kuderera panguva yekufamba.

• Yakanakisa kudzivirira kwezvakatipoteredza : Inomira kuratidzwa kweUV, unyoro, uye kushanduka kwetembiricha kubva -40°C kusvika 80°C.

• Kuchengeteka : Hapana mipendero yakapinza, inobvisa njodzi yekusvibisa ngura

PAC Strapping Products inocherekedza kuti PET tambo inosanganisa kusimba kwesimbi tambo nekuchengetedza uye hupfumi hwepurasitiki, zvichikonzera mitoro yakachengeteka pamutengo wakaderera.

1.3 Zvishandiso zvakajairika

PET tambo ndiyo yakasarudzika sarudzo ye:

• Mitoro inorema sezvidhinha, matanda, simbi, uye mitoro mikuru ine palletized

• Kuchengetera kunze uye kwakaomarara mamiriro ekunze

• Kuendesa kure-kure uko kuchengetedzwa kwekunetseka kwakakosha

• Zvishandiso zvinoda kuchinjwa kwetambo yesimbi

2. Chii chinonzi PP Strap?

2.1 Tsanangudzo uye Kuumbwa Kwezvinhu

PP tambo (polypropylene tambo) ipurasitiki isingaremi inogadzirwa kubva ku polypropylene resin. Iyo inogadzirwa neextruding, kutonhora, uye kutambanudza zvinhu kuti iwane molecular orientation inopa simba rakakwana rechiedza kusvika pakati-basa maapplication uchiramba uchichinjika.

2.2 Maitiro Akakosha Ekuita

PP tambo inopa mabhenefiti akasiyana kune mamwe maapplication:

• Yakareruka uye inochinjika : Zviri nyore kubata uye kushandisa

• High elongation : Inobvisa kuvhunduka uye inogadzika mitoro inomanikidzika

• Mutengo unoshanda : Yakaderera mutengo wezvinhu pane PET tambo

• Kusimba pakati nepakati : 100-150 MPa, inokodzera kureruka kusvika pakati mitoro

2.3 Zvishandiso zvakajairika

PP tambo ndiyo yakasarudzwa sarudzo ye:

• Makatoni, masumbu, uye mapallets akareruka kusvika pakati

• Unitized zvigadzirwa izvo zvisingawedzere kana kusimuka panguva yekufambisa

• Indoor, tembiricha-inodzorwa nharaunda

• Yakakwira-vhoriyamu, inodhura-isinganzwi kurongedza mabasa

3. PET Strap vs PP Strap: Side-by-Side Kuenzanisa

3.1 Simba uye Mutoro Kukwanisa

Musiyano wakanyanya kukosha pakati pePET nePP tambo iri mukusimba kwesimba uye mutoro wekutakura.

PET tambo yakavakirwa simba. Kusimba kwayo kwepamusoro kunoibvumira kuchengetedza zvinorema-basa pallets uye zvigadzirwa zvakaita sezvidhinha, matanda, kana simbi. PP tambo , neimwe nzira, inopa tension yakakwana ye-light-duty bundling uye inova nechokwadi chekubudirira kwemutengo wekushandiswa kwehuwandu.

3.2 Elasticity uye Tension Retention

Zvinoenderana neYS Strapping, PP tambo yakawedzera elastic uye inogona kutora kuvhunduka, asi inogona kurasikirwa nekunetsekana nekufamba kwenguva, ichiita kuti isakodzere kuchengetwa kwenguva refu kana kureba kutakura. PET tambo inopa kuchengetedza kwakanyanya uye kushoma kurebesa, zvichiita kuti ive yakanakira kutumira kunze kwenyika kana zvinhu zvakachengetwa kwenguva yakareba.

Signode anocherekedza kuti PET tambo ine yakaderera yakatambanudzwa kuchengetedza kushushikana nekufamba kwenguva, ine yakakwirira simba rekusimba rinofananidzwa netambo yesimbi kune inorema basa rekushandisa. PAC Strapping Products inosimbisa kuti PET inochengetedza tension yakakwira, ichigara yakasimba kupfuura simbi uye polypropylene, zvichikonzera kutakurwa kunoramba kwakachengeteka kunyangwe panguva yakakosha kufamba.

3.3 Kuramba Kwezvakatipoteredza

Mamiriro ekunze anogona kukanganisa zvakanyanya kuita kwetambo. Tambo yePP inogona kudzikisira pasi pekuratidzwa kweUV uye tembiricha yakakwira, zvichiita kuti ive yakanakira kushandiswa kwemukati kana kwenguva pfupi. PET tambo inopa yakakwirira kuramba kuUV mwenje, kupisa, uye kutonhora, zvichiita kuti ive yakanakira kuchengetedza kwekunze uye kutumira kune dzimwe nyika.

3.4 Kuenzanisa Kwemari

Mutengo unowanzoita basa rakakosha mukurongedza sarudzo. PP kusungirira kune bhajeti-inoshamwaridzika, yakanakira makambani anorongedza zvinhu zvisingaremi muhuwandu hukuru. PET tambo ine mutengo wepamusoro wepamberi, asi inoda kushoma kusungwazve uye kushoma kutsiva, ichipa zvirinani kwenguva refu kukosha kune inorema kana maindasitiri mitoro.

Zvinoenderana nemaindasitiri masosi, PET strap inogona kuderedza mari yekufambisa ne30-40% kana ichienzaniswa nedzimwe simbi uye inogona kushandiswazve 2-3 nguva, ichipa 20-25% mari yekuchengetedza pamusoro pesimbi.

3.5 Kuchengetedza uye Kubata

PET tambo ine mipendero yakatsetseka isina njodzi yekuchekwa kana kumwaya kana yatyoka. PP tambo inopawo zvakanakira kuchengetedza pamusoro pesimbi asi inogona kutsemuka zviri nyore pasi pemitoro inorema.

4. Ungasarudza sei Pakati pePET nePP Strap

4.1 Mamiriro ekusarudza

Paunosarudza pakati pePET tambo uye PP tambo , funga:

Sarudza PP Strap apo:

• Mitoro yakareruka kusvika pakati nepakati (pasi pe300kg)

• Packaging ndeyemukati, tembiricha-inodzorwa nharaunda

• Mutengo ndiwo mutyairi wekutanga

• Zvigadzirwa zvakabatana uye hazviwedzere kana kusimuka panguva yekufambisa

Sarudza PET Strap apo:

• Mitoro inorema kana yakaoma (zvidhinha, matanda, simbi)

• Zvigadzirwa zvichachengetwa kunze kana mumamiriro ezvinhu akaoma

• Zvinotakurwa zvinofamba nzendo refu zvinoda tension kuchengetedza

• Iwe unofanirwa kutsiva tambo yesimbi

Chikwata cheinjiniya cheJushuo Packaging chinopa kubvunzana kwekunyorera kubatsira vatengi kusarudza iyo chaiyo tambo zvinhu zvinoenderana nerudzi rwemutoro, mamiriro ekubata, uye mutengo zvinangwa.

4.2 Indasitiri-Yakananga Nhungamiro

Summary

PET tambo uye PP tambo inoshanda zvakasiyana zvinangwa mumaindasitiri ekurongedza. PET tambo inopa simba-sesimbi, kureba kwakadzika, kuchengetedza kwepamusoro-soro, uye yakanakisa kuramba kwezvakatipoteredza-ichiita kuti ive sarudzo yakasarudzika yemitoro inorema, kuchengetedza kwekunze, uye kutakura kureba. PP tambo inopa kuchinjika, kuvhunduka kunyura, uye mutengo unoshanda-yakanakira kureruka kusvika pakati mitoro mukati memukati, inodzorwa nharaunda.

Sarudzo pakati pePET nePP inofanirwa kuenderana nehuremu hwemutoro, mamiriro ekuchengetedza, kureba kwekutumira, uye kufunga kwebhajeti. Hapana chinhu chiri 'nani' pasi rose - sarudzo yakakwana inobva pane zvaunoda zvekushandisa.

Jushuo Packaging inopa akazara ese ari maviri PET uye PP mabhanhire ekugadzirisa, ane customizable zvirevo, zvakanyorwa vimbiso yemhando, uye kuvimbika kweketani. Kugona kwedu kugadzira — 4 PET uye 5 PP mitsetse yekugadzira ine 20,000 matani epagore kugona, SSP viscosity control, uye 99% + mitengo yekupasa — iva nechokwadi chekushanda kwakafanana pamativi ese akatsanangurwa.

Kana iwe uchida rubatsiro kusarudza pakati pePET nePP tambo yebasa rako rekurongedza kana uine mibvunzo nezve zvakatemwa zvezvinhu, ndapota tumira email ku. sales@jushuopackaging.com , uye timu yedu yehunyanzvi ichapa rutsigiro rwemunhu-pamwe.
