Ntawv-yas composite hnab

Feem ntau cov txheej yas yog ua los ntawm cov ntaub npuag tiaj tus nrog PP lossis PE ua cov khoom siv hauv paus, thiab sab nraud yog ua los ntawm cov ntawv dawb kraft lossis cov ntawv daj. Kraft daim ntawv yog ua los ntawm refined composite tshwj xeeb kraft ntawv, uas muaj cov yam ntxwv ntawm siab zog, zoo dej kuj thiab zoo nkauj tsos. Nws yog ib qho ntawm cov khoom ntim nrov tshaj plaws thiab siv dav hauv cov khoom noj, khaub ncaws, khoom plig thiab lwm yam lag luam. Cov hnab ntim khoom sib xyaw tuaj yeem muab faib ua cov hnab ntim rov qab, lub hnab ntim peb sab, lub hnab ntim khoom, lub hnab zipper sawv ntsug, hnab ntim plaub sab, hnab ntim tshwj xeeb, thiab lwm yam.

Stand-up hnab yog laminated los ntawm PET / foil / PET / PE qauv, thiab tuaj yeem muaj lwm yam tshwj xeeb xws li 2 txheej thiab 3 txheej. Raws li cov khoom sib txawv ntim, cov txheej txheem tiv thaiv cov pa oxygen tuaj yeem ntxiv raws li xav tau los txo cov pa oxygen permeability thiab ua kom lub neej ntev ntawm cov khoom.

Raws li lub hauv paus ntawm lub hnab sawv ntsug zoo tib yam, peb tau tshaj tawm ntau qhov zoo-seal hauv qab sawv ntsug hnab, uas muaj cov txiaj ntsig hauv qab no:

1. Cov qauv ntsug, tuaj yeem sawv ntsug ntawm lub txee qhuav, lub xwmfab yog tiaj tus, thiab qhov chaw ruaj khov.

2. Cov zipper sealing ntxiv tuaj yeem muab ntxiv kom tsis txhob muaj qhov tsis zoo uas lub hnab ntim khoom tsis tuaj yeem zippered.

3. Ib txoj kev tso pa tawm tuaj yeem txuas nrog, uas tuaj yeem siv rau hauv kas fes thiab lwm yam kev lag luam.

4. Cov khoom ntim khoom sib xyaw ua ke tuaj yeem ua ke los ua kom muaj kev sib txawv tsis zoo los ntawm cov dej thiab cov pa oxygen permeability ntawm cov khoom sib txawv.
