Mabigat man ang laman,
dapat panatag pa rin ang loob

Heavy-Duty Paper Bags | Cement Bags · Chemical Bags · Feed Bags · 25kg Industrial Kraft Paper Bags

Ang mabigat na pakete na sako ng papel ng Chia Huang ay gumagamit ng multi-layer long-fiber kraft paper bilang core, na nagbibigay ng balanseng lakas ng pagdadala, resistensya sa moisture, at resistensya sa pagkapunit — isang maaasahang pagpipilian para sa 25kg na pakete sa industriya ng semento, kemikal, feeds, at pataba sa agrikultura.

Heavy-Duty Bags

Heavy-duty paper bags, bearing strength is the bottom line

Kapag napunit ang sako, hindi lang ang laman ang nawawala — maaaring mahinto ang buong production line, gumuho ang mga pallet, o maging sanhi ng reklamo mula sa mga customer sa downstream. Kaya naman para sa mabigat na pakete, hindi maaaring ikompromiso ang lakas ng pagdadala at resistensya sa pagkapunit.

Ang mabigat na pakete na sako ng papel ng Chia Huang ay gumagamit ng long-fiber kraft paper, kung saan ang long-fiber structure ay nagbibigay ng mas mataas na lakas ng pagdadala at resistensya sa pagkapunit, na kino-customize pa ang bilang ng layers at functional processing ayon sa katangian ng laman.

From 25kg cement bags to specialized chemical bags, this product line covers the core heavy-duty packaging needs of manufacturing.

FAQ

Heavy-duty paper bag FAQs

What is the maximum weight capacity of heavy-duty paper bags? Is 25kg the limit?

Ang 25kg ay ang pinakakaraniwang specification para sa mabigat na pakete tulad ng semento at pataba, ngunit hindi ito ang limitasyon. Maaaring i-customize ng Chia Huang ang sako ng papel na may iba't ibang kapasidad sa pagdadala, ayon sa katangian ng laman, sa pamamagitan ng pag-adjust ng bilang ng layers at istruktura ng materyales. Kapag humihingi ng quotation, ipaalam ang bigat ng laman at paraan ng pagpuno, at magbibigay ang aming sales team ng angkop na mungkahing istruktura.

Will contents absorb moisture? Is the paper bag moisture-proof enough?

Para sa mga laman na madaling humigop ng moisture, maaaring pumili ng optional na coating (PE/PP) sa ibabaw ng multi-layer structure upang palakasin ang resistensya sa moisture, o dagdagan ang bilang ng layers. Ang aktwal na solusyon ay depende sa sensitivity ng laman sa moisture at kondisyon ng imbakan. Tingnan ang Coating Processing para sa detalye.

Can we print our brand LOGO?

Oo, posible. Nag-aalok ang Chia Huang ng 4-color printing, na maaaring mag-print ng brand logo at disenyo, angkop para sa mga produktong tulad ng feeds at pataba sa agrikultura na nangangailangan ng brand recognition. Pagkatapos magbigay ng design file, makakapagbigay kami ng digital file ng layout ng printing at katulad na sample ng bag style bilang reperensya.

Our filling line is automated; are the paper bags compatible?

May malawak na karanasan ang Chia Huang sa pakikipagtulungan sa automatic filling production lines, at maaari kaming mag-disenyo ng bag style at exhaust structure ayon sa specification ng iyong filling equipment. Kapag humihingi ng quotation, ibigay ang impormasyon tungkol sa paraan ng pagpuno at kagamitan, at susuriin ng aming sales team ang compatibility.
