Hunhu Maitiro echivhariso chakatambanudzwa firimu kuperekedza

Data2020-06-03

Pasinei nebudiriro yetekinoroji, kusvika parizvino chinhu chakakosha chinokanganisa mhando kana yakakwirira chipingamupinyi chakatambanudzwa firimu zvinhu uye magadzirirwo ekugadzira, yakakwira barriers yakatambanudzwa firimu repamusoro pekuita chikonzero nei nekuti ine inotevera maitiro.

Kuti utore mukana panguva imwe chete yezvivakwa zveakasiyana mapolymers, anowanzo shandiswa mukurongedza iyo multilayer chimiro, iyo multilayer barriers stretch film process ndiyo yakafanana muchimiro chemufirimu chinoumbwa kubva kune akasiyana mapolymers, imwe neimwe polymer inogona kuve kemikari. uye hunhu hwepanyama hwezvakanakira izvo zvinopihwa kune imwe, uye mhinduro dzekusangana neindasitiri yezvekudya, mishonga uye zvimwe zvakakosha zvezvinhu zvekurongedza, kunyanya muzvidzidzo zvehunyanzvi PA.EVOH a film barrier material.

Barrier stretching film packaging used physical method process, kusarudzwa kwezvinhu zvinozivikanwa pasi rose zvakatipoteredza kubva pakurwiswa, uye zvino kunyanya kushandisa composite kurongedza hazvina kufanana, usashandise zvinonamira, haina simbi inorema, asi hapana yakasara dambudziko rekunyungudutsa, girini, kurongedza zvokudya zvakachengeteka.

 CHERECHEDZA: chipingamupinyi chakatambanudzwa firimu chakaitwa nepurasitiki zvinhu zvine gasi rinopfuta uye rinokuvadza, pasi pe5 ~ 35 ℃ chengetedzo kuchengetedza yakaoma uye ine mhepo yekuchengetera nharaunda, kure nekupisa uye ingangoita 1 mita kure.
