VII. Four Key Factors Affecting the Moisture-Proof Performance of 8079 Aliminyum folyo
Even among 8079 moisture-proof aluminum foil products, the moisture-proof effect can vary greatly between manufacturers. Performance is primarily influenced by four major factors: kalınlık, iğne delikleri, işlem, ve depolama. These are also core checkpoints for quality control.
7.1 Alüminyum Folyo Kalınlığı
Aluminum foil thickness is directly proportional to moisture barrier stability. Greater thickness results in higher base material density and stronger anti-permeation capability, leading to better stability in high-humidity environments.
Industry-preferred conventional thicknesses are: 7mikron, 9mikron, 12mikron, 15mikron, 20mikron. Bunların arasında, 7-12μm suits conventional food packaging, while 15-20μm suits high-requirement barrier scenarios like pharmaceuticals and electronics.
7.2 Number and Size of Pinholes
Pinholes are the core vulnerabilities for moisture penetration. Fewer pinholes and smaller aperture sizes result in better moisture-proof effectiveness.
High-end quality 8079 aluminum foil undergoes multiple precision rolling and filtration steps to remove impurities, achieving near-zero pinholes even in ultra-thin specifications, completely eliminating moisture penetration channels.
Inferior products have densely packed pinholes, drastically reducing moisture-proof performance.
7.3 Post-Lamination Process
The moisture-proof capability of aluminum foil relies on a perfect composite structure. The quality of adhesives, lamination uniformity, ve ısı yalıtımı bütünlüğü nihai bariyer etkisini doğrudan belirler.
Kalitesiz tutkal eskimeye ve delaminasyona eğilimlidir; Düzensiz laminasyon kabarcıklar ve boşluklar oluşturur; Eksik ısı yalıtımı sızıntıya neden olur ve bunların tümü genel nem bariyerini yok eder.
7.4 Bitmiş Ürün Depolama ve Taşıma Ortamı
8079 alüminyum folyo bobinler ve lamine bitmiş ürünler sabit sıcaklık ve nem depolaması gerektirir.
Yüksek sıcaklığa uzun süre maruz kalma, yüksek nem, asit, alkali, or corrosive environments can cause surface oxidation of the aluminum foil, damage to the composite layer, and coil deformation, destroying the barrier structure and ultimately reducing moisture-proof performance.
A standardized warehousing environment is a crucial link in ensuring stable product performance.
