Sezvo nyika inowedzera uye yakanyanya kuomararautongi hwekuchengetedzwa kwezvakatipoteredza, kuguma kwevatengi kutsvaga kukwana, maitiro ekuona uyezvakasvibirira zvakatipoteredzaKudzivirirwa kwekurongedza kwechigadzirwa chemhando dzakasiyana-siyana kwakakurudzira varidzi vazhinji vemhando kuti vawedzere chinhu chebepa kune dhizaini yekurongedza.Kusanganisira mupepeti pachake, iniwo ndinoda mapepa kurongedza zvakanyanya, uye ini ndinowanzo tora mamwe mabhegi ekurongedza emhando iyi.Zvigadzirwa zvekambani yedu zvakapedzwa zvinoshamisa zvakare, senge acoffee kraft paper zipper bag ine air valveizvo zvatichangobva kuita munguva pfupi yapfuura.
Dhizaini yepepa-yepurasitiki inosanganiswa packaging inyaya uye yakasarudzika, iyo yakaunza zvinoshamisa maitiro ekuita kune varidzi vemhando.Nekudaro, mukugadzira maitiro,, iwo anoumbwa maitiro anoshandiswa anosanganisira yakaoma composite, extrusion composite, solvent-isina musanganiswa, nezvimwe, izvo zvinoita kuti mamwe maitiro asagadzikane, senge akawanda emarara, kunhuwa, yakakwirira solvent masara, nezvimwe. Matambudziko akadai sekuvhara kupisa uye kuputika.Kuti uvandudze kunaka kwepepa-plastic composite packaging, zvakakosha kutanga nekugadzirisa pamusana pekunzwisisa kwakadzama kwemhando iyi yekuputira, kuitira kuti uwane kaviri chigumisiro nehafu yekuedza.
1. Mamiriro ezvinhu aripo epa-plastic composite packaging
Panyaya yechimiro, kune akasiyana siyana emapepa-epurasitiki ekugadzira zvigadzirwa pamusika, anowanzo kupatsanurwa kuita OPP//PAP, PET//PAP, PAP//CPP(PE), PAP//AL, etc. Kubva muchikamu. yepepa: mhando yega yega inosarudza marudzi akasiyana emapepa, ukobvu uye uremu hwepepa zvakasiyana, kubva pa20 kusvika ku100g.Nzira yekugadzira inosanganisiraextrusion compounding, yakaoma kusanganisa, solvent-isina kusanganiswa, nezvimwewo.
Kuburikidza nekuenzanisa kuri pamusoro, maitiro ega ega ane zvakanakira nekuipira.Mumashoko akareruka, zvigadziriswe-zvisina zvigadziriswe zvine zvakanakira mukushanda kwakazara, sekushanda, kurasikirwa, nezvimwewo. Kana huwandu hwekurongeka huri hudiki uye kurongeka kwakaoma, isu tichiri kukurudzira yakaoma kusanganisa (teerera kusarudzwa kwepepa, glue. , nezvimwewo).
2. Kusarudzwa kwezvinhu
Kune marudzi akawanda ezvigadzirwa zvemapepa zvinogona kushandiswa kugadzira mapepa epurasitiki anoumba zvinhu, zvinosanganisira bepa rakavharwa, chena kraft bepa, yero kraft bepa, rinonamira kaviri, bepa rekunyora, rakavharwa nechiedza, pearl bepa, nyoro pepa retishu, base bepa, zvichingodaro, uye zvinoenderana nekurongedza dhizaini zvinodiwa, inogona kugadzirwa kuita akasiyana akaumbwa zvinhu zvimiro, seOPP/ bepa, PET/ bepa, CPP// bepa, PE// bepa, AL// bepa, nezvimwe.
Kune angangoita gumi nemaviri ezvikamu zvinoenderana nekushandiswa kwakasiyana, maitiro, nezvimwewo, anowanzo shandiswa mumunda wekurongedza anochinjika ndeye kraft bepa, chena kraft bepa, nyoro bepa rekotoni, base bepa, pearl bepa, nezvimwe, huwandu hwehuwandu kubva ku25gsm. kusvika 80gsm.Nekuda kwekusiyana kwakasiyana kwepepa uye kushandiswa kwakasiyana, zvinotevera pfungwa dzinofanirwa kutariswa kana uchishandisa pepa rakasiyana:
① - Kazhinji kutaura, rutivi rwakatsetseka rwepepa rwuri nyore kusungirirana nefirimu, nepo rutivi rwakakasharara uye firimu racho rakaoma kubatanidza.Izvi zvinonyanya kukonzerwa nemakomba nemakomba ari padivi rakashata.Adhesive inozadza maburi.
②Teerera kune density yepepa.Mafiibha emamwe mapepa akasununguka.Kunyange zvazvo bepa uye firimu zvakanyatsobatanidzwa kana zvakasvibiswa, zvinowanzoita delamination mushure mekupisa chisimbiso.
③ Hunyoro hwemukati hwebepa zvakare hune imwe pesvedzero pane yekubatanidza maitiro.Zvinoenderana neruzivo rwemunhu, mwando wepepa haufanire kudarika 0.4%.Ipfungwa yakanaka kusiya pepa muchoto kwemazuva 1 kusvika 2 isati yagadzirwa
④ Chengetedza kuchena kwepepa repamusoro.
3. Magadzirirwo ekugadzira
Paunenge uchigadzira chimiro chebepa-purasitiki yekurongedza mudziyo, zvinodikanwa kuti unzwisise zvimiro zvepakeji uye sarudza yakakodzera zvinhu uye chimiro.
Panyaya yekugadzirwa kwebhegi, inonyanya kushandiswa kurongedza zvinhu zvakasimba, uye chimiro chakapfava.Tichifunga nezve basa rekurongedza uye zvigadzirwa zvekuratidzira zvinodiwa, chimiro chinogona kukamurwa kuva marudzi matatu: hapana hwindo remhando, strip hwindo mhando uye yakakosha-yakaita hwindo.
Bhegi risina hwindo ndiro rinowanzozivikanwa bhegi-mhando chimiro.Muviri mukuru ipepa zvinhu (senge kraft paper), uye mukati nekunze zvidimbu zvinowanzochengetedzwa nemafirimu epurasitiki akadai sePE (polyethylene) uye PP (polypropylene), iyo inogona kunyatsovhara unyoro uye oksijeni kudzivirira kugutsikana. , uye maitiro ekuumba akafanana neaya epurasitiki anochinjika kurongedza.Kutanga, pepa racho rinosanganiswa nefirimu yepurasitiki uyezve kupisa-kuvharwa kuita mabhegi;
Iyo bhagi remahwindo bhegi uye yakasarudzika-yakaita hwindo ndeyemhando yefafitera chimiro bhegi, uye bepa rinoshandiswa kugadzira mativi emhepo maburi, kuitira kuti kurongedza kunogona kuratidza akasiyana masitaera.Pamusoro pekuchengetedza kujeka kwebhegi rekurongedza, rinogona zvakare kuve nekugadzirwa kwepepa.Nzira yekugadzira bhegi remahwindo ndeyekubatanidza firimu repurasitiki rakatetepa-paupamhi uye mapepa maviri emapepa nerimwe firimu repurasitiki rakafara.Pane nzira mbiri dzekugadzira mahwindo akasarudzika.Imwe ndeyekuvhura hwindo mune zvemapepa zvinhu pachine nguva kuti uite maumbirwo akasiyana, uye wozobatanidza zvinhu.Izvo zvinhu zveiyo composite layer zvinogona zvakare kushandurwa uye kugadzirwa munzvimbo yakakura kuvandudza kuchinjika kwemaitiro ekugadzira.
4. Nzira yekugadzira
Iyo yakaoma yekubatanidza maitiro inenge yakakura.Mabhizinesi anosarudza solvent-based two-component glue, uyewo sarudza-single-component glue uye mvura-based glue.Pano isu tinokurudzira kuti zvisinei kuti chii chinoshandiswa glue, zvinotevera zvinofanirwa kutariswa kune:
a.Kusarudzwa kwepepa kunokosha zvikuru;
b.Kudzora kwehuwandu hwemvura pamapepa;
c, pepa glossy uye matte kusarudzwa;
d.Ngwarira kuchena kwepepa;
e, kutonga kwehuwandu hweglue;
f.Kumhanyisa kudzora kudzivirira masara esolvent kubva pakunyanya kukwira.
