በፋርማሲቲካል ማሸጊያ መስክ, PVC (ፖሊቪኒል ክሎራይድ) እና pvdc (ፖሊቪኒል ክሎራይድ / ፖሊቪኒል አሲቴት ኮፖሊመር) ብዙውን ጊዜ በአሉሚኒየም ፎይል ለመልበስ ያገለግላሉ. Both have certain strengths and applicability, but may have different applications in specific situations.

PVC and aluminum foil composite:

እንቅፋት አፈጻጸም: The composite film of PVC and aluminum foil has good oxygen and water vapor barrier performance, which can protect medicines from the influence of moisture and oxygen.
ግልጽነት: PVC and aluminum foil composite film can have a certain degree of transparency, making the medicines in the package visible and easy to observe.

ኬሚካዊ የመቋቋም ችሎታ: PVC and aluminum foil composite film has a certain chemical resistance, which can protect the drug from the influence of the external environment.

ወጪ ቆጣቢነት: The cost of PVC and aluminum foil lamination is relatively low, which is suitable for some affordable pharmaceutical packaging needs.

PVDC and aluminum foil composite:

ከፍተኛ እንቅፋት አፈፃፀም: The composite film of PVDC and aluminum foil has excellent oxygen and water vapor barrier performance, which can better protect drugs from oxygen, moisture and other external factors.
High chemical resistance: PVDC and aluminum foil composite film has excellent chemical resistance, which can effectively protect the stability and expiration date of drugs.

ደህንነት: PVDC is generally regarded as a food-grade material with good safety and stability.
Applicable to humidity-sensitive pharmaceuticals: PVDC and aluminum foil composite film has good barrier performance to moisture, and is suitable for humidity-sensitive pharmaceutical packaging.

ስለዚህ, the choice of PVC and aluminum foil composite or PVDC and aluminum foil composite should be comprehensively considered according to the characteristics of specific drugs, የማሸጊያ መስፈርቶች, cost factors, እና የቁጥጥር መስፈርቶች. In some pharmaceutical packaging that requires high barrier properties and is sensitive to humidity, PVDC and aluminum foil composite films may be more suitable; while in some cases that are more sensitive to cost requirements, PVC and aluminum foil composite films may have more advantages.
