Cold-Formed Blister Packaging: The Premium Choice for High-EndPharmaceutical Solutions_foil_the_and
发布日期：2025-06-26 06:01 点击次数：98
Cold-formed blister packaging delivers exceptional barrier properties, reliable sealing, and operational efficiency, making it the preferred solution for premium pharmaceutical packaging. The cold-stamped rigid film typically comprises three functional layers:
Surface strength support layer
Middle aluminum foil barrier layer
Inner heat-seal layer
8021 aluminum foil

Role & Advantages of 8021 Foil in Cold-Stamped Blister Packaging
Unlike conventional flexible packaging, the aluminum foil barrier layer in cold-stamped blisters must provide:
✅ Triple-function performance: Barrier protection + structural support + stamping resistance
✅ Optimized mechanical properties:
High strength withstands pressure/impact to protect products
Exceptional elongation (≥3%) prevents cracking/deformation during stamping
Ensures blister cavity precision and dimensional stability
✅ Unmatched barrier protection:
Blocks >99.9% oxygen, moisture, and UV penetration
Extends shelf life of sensitive pharmaceuticals and nutraceuticals
✅ Enhanced processability:
Superior printability for brand customization
Excellent heat-sealing performance (seal strength ≥3.5N/15mm)
