Kemasan fleksibel untuk biji kopi dan kopi bubuk

Jenis Kemasan yang Direkomendasikan

• Coffee bags with one-way degassing valve (essential for freshly roasted coffee releasing CO2), flat bottom pouches (five printable panels, box-like shelf stability for premium brands), stand-up zipper pouches (bottom gusset, resealable zipper, cost-effective for retail), kraft paper bags (natural kraft appearance with barrier lamination for organic/specialty coffee). Side gusset bags and quad seal pouches are also available for larger volume coffee packaging.
• PET/VMPET/PE (most common for coffee, good moisture and light barrier with metallic appearance), Kraft/VMPET/PE (natural kraft look with improved barrier for organic brands), PET/AL/PE (strongest oxygen, moisture and light barrier for aroma-sensitive coffee; cost is higher), PET/EVOH/PE (transparent high-barrier option for product visibility). The final structure should be confirmed based on coffee type (whole bean/ground), roast level, shelf life target, storage conditions and valve/zipper requirements.
• Each batch undergoes print color check, lamination bond strength test, heat seal strength test (ASTM F88), valve function verification (one-way flow test), zipper opening/closing durability test, aroma barrier testing (OTR), moisture barrier testing (WVTR), puncture resistance test and visual appearance inspection. Pre-shipment inspection with retained batch samples.
• Coffee type (whole bean/ground/instant), roast level and degassing rate, filling weight and target bag dimensions, bag style (flat bottom/stand up/side gusset), valve requirement and valve position, zipper type (press-to-close/slider), material structure preference, surface finish (matte/gloss/kraft), printing colors and artwork file, estimated order quantity, target shelf life and storage conditions, destination country or region.
• Coffee Bags with Valve, Flat Bottom Pouches, Stand Up Zipper Pouches, Kraft Paper Packaging Bags, Side Gusset Bag, Quad Seal Pouches, Food Packaging Roll Film.
• Q: What packaging is best for coffee beans? A: Coffee bags with one-way degassing valve. The valve releases CO2 from freshly roasted beans while preventing oxygen from entering. Q: Can coffee bags be made with kraft paper look? A: Yes, kraft/AL/PE or kraft/VMPET/PE laminated structures combine natural kraft appearance with barrier protection. Q: What material structure keeps coffee fresh longest? A: PET/AL/PE provides the strongest oxygen, moisture and light barrier. The specific structure should match your roast level and shelf life target. Q: Can coffee packaging have both valve and zipper? A: Yes, valve and zipper are standard options for most coffee bag formats.

Saran Material

Material recommendations by product type: dry products typically use PET/PE or BOPP/CPP; oily or high-aroma products benefit from PET/VMPET/PE or PET/AL/PE for better barrier; liquids and sauces need NY/PE or PET/AL/PE for chemical resistance and leak-proof sealing; frozen products use cold-resistant PE layer; high-temperature sterilization uses PET/AL/CPP or PET/AL/PA/CPP retort-grade structures. Huasheng Packaging recommends suitable structures based on specific product type and shelf life requirements.

Poin Kontrol Kualitas

Each batch undergoes: print color consistency check, lamination bond strength test, heat seal strength test, dimensional tolerance measurement, visual inspection. Application-specific: puncture resistance, chemical resistance, moisture barrier, cold impact resistance, seal integrity (leak/burst). Pre-shipment inspection with retained samples.
