Mabhokisi efodya emhando chena ane seti yekuratidzira (seti yega yega yemabhokisi gumi, bhokisi rega rega rine mapaketi manomwe)

Kadhibhodhi jena ipepa gobvu rine kusimba uye huremu hwakakura. Nekuti pamusoro paro hapana ruvara, rinowanzonzi kadhibhodhi jena. Kadhibhodhi jena rekuChina rakakamurwa kuita magiredhi matatu A, B, C. Kuchena kwegiredhi A hakusi pasi pe92%; B haisi pasi pe87%; C haisi pasi pe82%.
Zvinhu zvakabikwa pakadhibhodhi chena zvine 100% bleached chemical
Makadhibhodhi machena emapaketi efodya anoda kuomarara kwakanyanya, kuramba kutyoka, kutsvedzerera uye kuchena. Zvinodiwa pamusoro pepepa zvakati sandara, hapana mitsetse, mavanga, maburi uye mapundu, kutenderera uye kuchinja kwekugadzirwa. Sezvo paketi yefodya ine kadhibhodhi machena ichinyanya kushandisa muchina wekudhinda wegravure unokurumidza kudhinda, saka zvinodiwa zve cardboard tension index zvakanyanya. Kuramba kwekumanikidzwa kunozivikanwawo sesimba rekudhonza kana simba rekudhonza, zvinoreva kushushikana kwakanyanya kunogona kutsungirira bepa kana ratyoka, kunoratidzwa mu kN/m. Muchina wekudhinda wegravure unokurumidza kudhonza mapepa, kudhinda nekukurumidza kutsungirira kushushikana kukuru, kana chiitiko chekutyoka kwepepa kazhinji, chinosungirwa kukonzera nguva yekudonha kazhinji, kuderedza kushanda, asi zvakare kuwedzera kurasikirwa kwepepa.
Kune mhando mbiri dzemakadhibhodhi machena emapakiti efodya, rimwe iFBB (yellow core white card), rimwe iSBS (white core white card), mapaketi efodya anoshandisa FBB neSBS ari makabhodhi machena akaputirwa nerutivi rumwe chete, FBB ine zvikamu zvitatu zvepulp, chikamu chekumeso nechepasi chichishandisa sulfate wood pulp, chikamu chikuru chichishandisa chemical mechanical grinding wood pulp. Rutivi rwepamberi (printing side) ichikamu chekufukidza, chinoiswa nezvidimbu zviviri kana zvitatu, nepo chikamu chekumashure chisina chikamu chekufukidza. Sezvo chikamu chepakati chakagadzirwa nemapuranga emapuranga akakuyiwa nemakemikari uye nehunyanzvi, pulp ine goho rakakura rehuni (85%-90%), uye mutengo wekugadzira wakaderera, saka mutengo weFBB cardboard wakaderera.
FBB pulp ine fibers refu uye fibers diki shoma uye fiber bundles, saka ukobvu hwepepa rapera huri nani, uye gramu imwechete yeFBB yakakora kupfuura SBS, iyo inowanzo umbwa nezvikamu zvitatu zve pulp, chikamu chepamusoro, chikamu chepakati nechikamu chepasi zvese zvinoshandisa bleached sulfate wood pulp. Rutivi rwepamberi (divi rekudhinda) i coating layer, iyo inoiswa kaviri kana katatu ne squeegee yakafanana neFBB, nepo reverse side isina coating layer. Sezvo core layer yakagadzirwawo ne bleached sulfate pulp, kuchena kwacho kwakanyanya, saka inonzi white core white card. Panguva imwe chete, pulp fibers idiki uye bepa racho rakamanikana, saka SBS yakatetepa kupfuura FBB ine huremu hwakafanana hwe gram. Semuenzaniso, ukobvu hwe 230g/m2 FBB yeHongta Renheng huri 320μm, nepo ukobvu hwe 230g/m2 SBS huri 295μm.
