As a high-end flexible packaging substrate with superior barrier properties, 8079 O-temper 0.013mm aluminum foil has become the core barrier layer in premium coffee stand-up pouches, vacuum fresh-lock bags, one-way valve coffee bags, and drip coffee packaging. It is widely recognized as the “heart of freshness preservation” for specialty coffee packaging.

mi. Ro-shealladh toraidh & Bun-buannachdan

8079 O-temper 0.013mm coffee packaging aluminum foil is an ultra-thin, soft-tempered foil made from the 8xxx series premium aluminum-iron alloy. It is manufactured through precision rolling, làn annealing, and precision slitting processes, specifically customized for high-barrier flexible laminates requiring aroma lock-in for premium food products. Unlike common 8011 general-purpose foil, this product maintains an extremely low pinhole defect rate, sùbailteachd sàr-mhath, and stable surface properties even at ultra-thin specifications. Tha e gu math freagarrach airson suidheachaidhean mòr-chinneasachaidh leithid lamination aig astar àrd, àrd-astar clò-bhualadh, cruthachadh falamh, agus pasgadh/seulachadh.

Faodar geàrr-chunntas a dhèanamh air na prìomh bhuannachdan aige ann an seachd prìomh tomhasan, gu cinnteach a’ freagairt ri riatanasan àrd pacaidh cofaidh sònraichte:

1. Lock Aroma Àrd-chnap-starra mu dheireadh

Bidh an còmhdach tiugh meatailt a’ coileanadh tar-chuir ocsaidean faisg air neoni (OTR), sgaoileadh bhalbhaichean uisge neoni (WVTR), agus sgaoileadh solais neoni, a’ glasadh gu daingeann ann an todhar cùbhraidh cofaidh agus a’ cur casg air call blas no crìonadh oxidative.

2. Ìre easbhaidh toll-pìne ultra-ìosal

Tha an 8079 tha alloy a’ tabhann seasmhachd air leth ann an roiligeadh ultra-tana. Aig an aon thiugh 13μm, tha an àireamh tuill prìne aige gu math nas ìsle na àireamh foil àbhaisteach, cuir às do chunnartan bho aoidion falaichte no taiseachd a’ tighinn a-steach aig an stòr.

3. Sàr-mhath O-Temper Ductility & Formability

Tha an teòthachd bog làn annealed a’ toirt seachad deagh sheasamh an aghaidh lùbadh, tuiteam falamh, agus pògan poca, dèanamh cinnteach nach bi meanbh-sgàinidhean ann nuair a thathar a’ cruthachadh, mar sin a 'cumail suas ionracas bacaidh.
