Product Information

What this product is used for — Coffee bags with valve and zipper are commonly used for roasted coffee beans and ground coffee packaging. Flat bottom, stand up and kraft paper laminated structures can be selected based on shelf display, aroma protection and barrier requirements. Common options may include PET/VMPET/PE, Kraft/VMPET/PE or aluminum foil laminated structures. Buyers should provide bag size, filling weight, valve requirement, zipper requirement, material preference, surface finish (matte/gloss), quantity and artwork before quotation.

バルブ、ジッパー、バッグスタイルオプション

Valve, Zipper and Bag Style Options — Coffee bag performance depends on both material barrier and functional accessories. A one-way degassing valve helps release carbon dioxide from roasted coffee while reducing outside air entering the bag. Resealable zipper or pocket zipper options help consumers close the bag after opening. Bag styles: flat bottom coffee bag (box-like shelf stability, five printable panels), stand up coffee pouch (bottom gusset, cost-effective), side gusset coffee bag (expandable sides for larger volume). Buyers should confirm valve position, zipper type, bag style and surface finish (matte/gloss) before production.

  • Heat seal inner layer — PE for standard coffee bags, selected for sealing strength and food contact safety
  • One-way degassing valve — allows CO2 from freshly roasted coffee to escape while reducing oxygen ingress; valve position confirmed during artwork design
  • Resealable zipper — press-to-close or slider zipper for consumer reclosure after opening; zipper type and position reviewed with bag design
  • Bottom gusset or flat bottom — expands when filled for stable shelf standing; bottom panel size confirmed with filling weight

よくある質問

Why do coffee bags need a degassing valve?

Fresh roasted coffee can release carbon dioxide after packing. A degassing valve helps release gas from the bag while reducing outside air entering the package, which helps protect aroma and reduce bag swelling risk.

What bag types are commonly used for coffee packaging?

Common coffee packaging formats include flat bottom coffee bags, stand up zipper pouches, side gusset bags and kraft paper laminated coffee bags. The choice depends on filling weight, shelf display, zipper requirement and brand design.

What material structure is suitable for coffee bags?

Coffee packaging often needs good aroma, oxygen and moisture barrier. Common structures may include PET/VMPET/PE, PET/AL/PE, kraft paper laminated structures or other high-barrier options. The final structure should be confirmed based on shelf life and storage condition.

Can coffee bags be customized with zipper and matte finish?

Yes. Coffee bags can be customized with zipper, degassing valve, matte finish, glossy finish, kraft paper surface, rounded corners and custom printing. The exact options depend on bag type, size and order requirements.

What information should I provide for a coffee bag quotation?

Please provide bag type, size, filling weight, material preference, valve and zipper requirement, printing colors, quantity, artwork file and destination country. If you have an existing coffee bag sample, photos can help us review the structure more accurately.
