Imishini eminingi esetshenziswayo ye-co-extrusion ingaveza obala. Umbala ophindwe kabili, i-monochrome, umbala ogcwele kanye nohlobo oluhlukahlukene lweshidi le-OO .Futhi ishidi le-PP lisebenza ekupakisheni kokudla, ithreyi lamahhala, izitsha zokulahla, ukupakisha ngogesi, i-tableware elahlwayo neminye imikhiqizo yochungechunge.

1. Ubuningi 
Ishidi le-PP ubukhulu obuncane bawo wonke amashidi, kuphela u-0.90-0.93g / cm3, cishe u-60% wobukhulu be-PVC .Lokhu kusho ukuthi ngesisindo esifanayo sezinto eziluhlaza kungakhiqiza imikhiqizo eminingi yevolumu efanayo.

Izici 2.Thermal 
Kupulasitiki ojwayelekile ojwayelekile, ukuzinza kwe-PP thermo yiyona engcono kakhulu. Imikhiqizo yepulasitiki ingasebenza amahora amaningi ngaphansi kuka-100 ° c, ngokungabi bikho kwamandla angaphandle, imikhiqizo ye-PP ngeke ikhubazeke lapho ishubile ibe ngu-150 ° c. Ngemuva kokusebenzisa i-ejenti ye-nucleating ithuthukise i-crystallization ye-PP, ukumelana kwayo nokushisa nakho kungathuthukiswa, kungenza nemikhumbi yokudla efudumeza ngemicrowave.

I-3.PP ye-oxygen, i-carbon dioxide nomphunga wamanzi inamandla athile, uma kuqhathaniswa nenayiloni (i-PA) ne-polyester (i-PET) inomehluko osobala, wempahla ephezulu yesithiyo, njenge-PVDC, i-EVOH, umehluko mkhulu .Kodwa uma kuqhathaniswa ezinye izinto ezingezona ezepulasitiki, ukuqina kwegesi yayo kuhle impela .Ngokwengeza impahla yesithiyo noma ukumboza impahla yplastiki ebusweni, kungakhuphula kakhulu ukuqina kwegesi yayo.

PP ishidi ukusetshenziswa polypropylene resin njengoba impahla main eluhlaza. Faka inqubo ehlukahlukene ye-masterbatch toughening agent kanye ne-agent ekhanyayo.production ngokuxuba, i-plastic plastifying extrusion, i-Three-roll calendering, ukupholisa, i-traction kanye ne-rolling-up.PP ishidi linezici ezingezona ezinobuthi, ezinganambitheki, ezokuhlanzeka, amandla aphezulu womshini nokuhle ukumelana, lokho kungasetshenziselwa ukupakisha izimboni zezimboni, ezolimo nezithelo.

Ishidi le-PP aligcini nje ngokungenabuthi, alinambitheki, linenhlanzeko, linamandla amakhulu futhi limelana kahle, Futhi lingaphinde lisebenze kabusha. uhlobo lwezinto zokupakisha eziluhlaza.Iphepha le -PP lingenziwa ngemikhiqizo eyahlukahlukene ngokucubungulwa kwesibili njengokushisa okwenziwe ngokushisa. Ingasetshenziselwa ukupakisha kokudla ngokucubungula ibhokisi le-jelly, ibhokisi lokupakisha ubisi, ibhokisi lokudla okusheshayo, isitsha sesiphuzo esibandayo, ithileyi, into esebenza nge-microwave oven njalonjalo; Kusetshenziselwe ama-bubble caps kungasetshenziselwa amaphilisi ezemithi, amaphilisi namanye amalungiselelo aqinile Ukupakisha. Emazweni angaphandle, ikakhulukazi emazweni athuthukile nasezifundeni, ishidi le-PP elibonakalayo lisetshenziswa kakhulu ekupakisheni ukudla.

Izici Zemikhiqizo ye-PP Plastic: isici semvelo, i-aesthetics, ukuphrinta kwesikrini, ukwakha, ukumelana nokushisa okuphezulu, ukumelana namazinga okushisa aphansi, ukungafihli lutho, ukumelana nokugoba kulula ukugoba, kungaba yi-microwave, Imikhiqizo ihlangabezana nezindinganiso zokuhlola ukudla.
Inkampani yethu ingaphinde ikhiqize i-PP ishidi elikhethekile lomshini wokwenza inkomishi, elifanele inkomishi yamanzi elahlwayo, itiye lobisi, inkomishi ye-jelly, ibhokisi lokupakisha kanye neminye imikhiqizo yesitsha.Lolu hlobo lweshidi lungamelana nemicrowave, ukumelana nokushisa okuphansi, ukwenza izinto obala okuphezulu, futhi ingamelana nokwelula okukhulu.

Okufakiwe Yekuchumana: Common Antistatic PS amashidi & imiqulu zigcwele cellophane & ifilimu futhi esigaxe umucu, bese wakufaka ejwayelekile esitsheni pallet
Imbozwe ngephepha lobuciko noma ifilimu le-PE ezinhlangothini ezimbili nge-pallet
Ukupakisha izimpahla ngobuningi: amathani ama-2 ngethreyi ngalinye, sebenzisa amaphalethi wokhuni ezansi, ngamaphakeji wefilimu okupakisha nxazonke aqinisekisa ukuphepha kokuhamba.
Ukupakisha umthwalo wesitsha esigcwele: amathani ayi-18-20 esitsha esinezinyawo ezingama-20 esinethreyi eli-10.
