Dab tsi yog qhov sib txawv ntawm cov tshuaj txhuas ntawv ci thiab zoo tib yam dawb ntawv?
Medicinal aluminum foil and ordinary aluminum foil differ significantly in terms of composition, Cov Khoom Siv, and applications.
Medicinal Aluminum Foil:
Made of high-purity aluminum (feem ntau 99% or more).
Manufactured under strict pharmaceutical-grade regulations (e.g., FDA or GMP compliance).
Coated or laminated with specialized materials (e.g., ntawv nplaum, lacquard) to enhance chemical resistance and compatibility with medications.
Ordinary Aluminum Foil:
Contains slightly lower purity aluminum.
May include small amounts of impurities or alloys for cost reduction.
Not subjected to stringent manufacturing standards or coatings.
Medicinal Aluminum Foil:
Generally thinner (6-20 microns) and more precisely controlled.
Excellent flexibility and easy to mold into blister packs.
Ordinary Aluminum Foil:
Typically thicker (10-50 microns) for household or industrial use.
Structural properties prioritize durability for cooking, kev rwb thaiv tsev, or packaging.
Medicinal Aluminum Foil:
Exceptional barrier against light, ya raws, oxygen, thiab cov paug.
Protects sensitive drugs from degradation and maintains shelf life.
Ordinary Aluminum Foil:
Good barrier properties but less demanding standards.
More prone to pinholes or imperfections that allow minor permeability.
Medicinal Aluminum Foil:
Often coated with materials like heat-seal lacquers or primer layers.
Designed for compatibility with pharmaceutical-grade plastics and inks.
Ordinary Aluminum Foil:
Usually uncoated or minimally treated.
Not suitable for direct contact with sensitive substances.
Medicinal Aluminum Foil:
Used in blister packs, Sawb Pob, and sachets for tablets, tshuaj ntsiav, thiab hmoov.
Prevents contamination and maintains sterility.
Ordinary Aluminum Foil:
Widely used for food wrapping, ua noj, kev rwb thaiv tsev, and general household or industrial packaging.
Non-sterile applications.
| Yam | Medicinal Aluminum Foil | Ordinary Aluminum Foil |
|---|---|---|
| Kev coj dawb huv | ≥ 99% | ~98% or lower |
| Thickness | 6-20 microns | 10-50 microns |
| Cov Khoom Siv Teeb Meem | Zoo tshaj (ya raws, teeb, gas-proof) | Good but less stringent |
| Txheej | Heat-seal lacquers, tseem chaws | Minimal or none |
| Kev cai | Strict (pharmaceutical standards) | General manufacturing standards |
| Daim ntawv thov | Blister/strip packs, drug packaging | Food wrap, kev rwb thaiv tsev, general use |
| Nqi | Higher due to stringent processing | Lower due to relaxed standards |
| Ntiag tug | Medicinal Foil | Ordinary Foil |
|---|---|---|
| Dej Vapor Xa Tus Nqi | ≤ 0.1 G / M² / Day | 0.5–1.0 g/m²/day |
| Oxygen Permeability | ≤ 0.01 CC / M² / HNUB | 0.1–0.5 cc/m²/day |
| Pinholes per m² | ≤ 5 | 10Mais -50 |
These figures highlight the stringent requirements of medicinal aluminum foil for pharmaceutical safety and stability.
