What Are The Processes Of Making a Flexible Packing Bag?

1. Kudhinda

Nzira yekudhinda inonzi gravure printing.Yakasiyana nedhijitari kudhinda, gravure kudhinda kunoda masilinda ekudhinda.Isu tinoveza magadzirirwo mumasilinda anoenderana nemavara akasiyana, tobva tashandisa zvakatipoteredza uye ingi yegiredhi rekudya kudhinda.Mutengo wecylinder unoenderana nemhando dzebhegi, saizi uye mavara, uye ingori imwe nguva mutengo, inotevera kana iwe ukarongedza imwe chete dhizaini, hapasisina mutengo wecylinder.Kunyange zvakajairika isu tichachengeta masilinda kwemakore maviri, kana mushure memakore maviri pasina kurongeka, masilinda anoraswa nekuda kweoxidation uye kuchengetedza nyaya.Iye zvino tawana michina 5 inodhinda inomhanya zvikuru, inogona kudhinda mavara gumi nekumhanya kwemamita 300 paminiti.

Kana iwe uchida kuziva zvakawanda nezve kudhinda, unogona kutarisa mavhidhiyo:

2. Laminating

Flexible bag inonziwo laminated bag, cos most flexible bag is laminated with 2-4 layers.Lamination ndeyekuzadzisa chimiro chebhegi rose, kuti uwane kushanda kwekushandisa kwebhegi.Surface layer ndeyekudhinda, inonyanya kushandiswa ndeye matt BOPP, inopenya PET, uye PA (nylon);yepakati layer ndeyekumwe kushandiswa kunoshanda uye nyaya yekutaridzika, senge AL, VMPET, kraft bepa, nezvimwe;yemukati layer inoita ukobvu hwese, uye kuita kuti bhegi rive rakasimba, chando, vacuum, retor, nezvimwe, zvinhu zvakajairika iPE neCPP.Mushure mekudhinda pamusoro pekunze kwepamusoro, isu tichava laminated yepakati uye yemukati layer, uye ipapo laminated navo nekunze kwejira.

Kana iwe uchida kuziva zvakawanda nezve kudhinda, unogona kutarisa mavhidhiyo:

3. Kusimbisa

Solidifying, ndiyo nzira yekuisa iyo laminated firimu mukamuri yekuomeswa kuita iyo main agent uye inoporesa adhesive ye polyurethane adhesive react uye cross-link uye kupindirana nepamusoro peiyo composite substrate.Chinangwa chikuru chekusimbisa ndechekuita kuti mumiriri mukuru uye mumiririri wekurapa aite zvizere mukati meimwe nguva yenguva kuti awane yakanakisa composite simba;yechipiri ndeyekubvisa yakasara yakanyungudutsa ine yakaderera kuvira, senge ethyl acetate.Solidifying nguva inobva kumaawa makumi maviri nemana kusvika kumaawa makumi manomwe nemaviri ezvigadzirwa zvakasiyana.

4. Kucheka

Kucheka ndiyo danho rekupedzisira rekugadzirwa, pamberi pedanho iri, zvisinei kuti ndeapi mabhegi awakaraira, ane roll rose.Kana iwe ukaodha mafirimu rolls, isu tinongozvimedura kuita saizi yakakodzera uye uremu, kana iwe ukaraira mabhegi akaparadzana, saka ndiyo nhanho yatinopeta nekuacheka kuita zvidimbu, uye zvakare iyi ndiyo nhanho yatinowedzera zipper, hang hole, kubvarura notch, chitambi chegoridhe, etc. Kune akasiyana muchina maererano nemhando dzakasiyana dzebhegi-flat bhegi, bhegi rekusimuka, bhegi rekudivi regusset uye mabhegi epasi.Zvakare kana iwe ukaodha mabhegi akaumbwa, iri zvakare nhanho yatinoshandisa mold kuapinza muchimiro chaunoda.

Kana iwe uchida kuziva zvakawanda nezve kudhinda, unogona kutarisa mavhidhiyo:
