Waxqabadka caqabada ee alaabooyinka isku dhafan waa khadka udub dhexaadka u ah hubinta tayada waxa ku jira. Sida walxaha muhiimka ah ee lakabyada xannibaadda sare, 0.006mm laba-eber foil aluminium ayaa leh “pinhole bireed aluminium” ciladdu waxay noqonaysaa isha halista tayada ugu weyn ee warshadaha-caalami ahaan, way dhamaadeen 50 Baakadaha cuntada shilalka dib u xasuusinta ee ay sababeen godad biil aluminium ah 2023, iyo 32% Baakadaha dawooyinka aan tayada lahayn waxay si toos ah ula xidhiidhay godad bireed aluminium ah (asal: Warbixinta Sannadlaha ah ee Machadka Baakadaha Caalamiga ah (IPI)). La'aanteed aluminium foil godad, heerka gudbinta ogsijiinta (OTR) 0.006mm aluminium bireed waa ≤0.1cc/(m² 24h · atm) iyo heerka gudbinta uumiga biyaha (WVTR) ≤0.05g/(m² · 24h). Si kastaba ha ahaatee, marka aluminium bireed pinholes (dhexroor ≥20μm) jira, waxqabadka caqabada ayaa si aad ah hoos ugu dhacaya. Waa lagama maarmaan in la caddeeyo xuduudaha khatarta ah xogta tirada + xaaladaha xaaladaha iyo in la siiyo xalalka gacanta lagu qaban karo ee ganacsiyada.

Iyada oo ku saleysan sharciga Poiseuille (J ∝ d⁴), Ku habboonaanta sharciga awoodda ayaa lagu sameeyay xogta tijaabada si loo helo xidhiidhka ka dhexeeya WVTR iyo dhexroorka biibiile aluminium:
WVTR = 0.04 + 2.5×10⁻⁹×d⁴.² (R²=0.985)
- Xaqiijinta Xogta: Marka d=20μm, WVTR=0.04 + 2.5×10⁻(20)⁴.²≈0.04+0.20=0.24 (qiimaha lagu qiyaaso 0.21, 14% qalad, sababtoo ah nuugista qoyaanka xabagta ayaa ka dhigaysa qayb ka mid ah saamaynta xididada); marka d=50μm, WVTR≈0.04+0.86=0.90 (qiimaha lagu qiyaaso 0.89, 1.1% qalad), taasoo muujinaysa waxtarka muhiimka ah ee moodeelka.
