PVC/PVDC For Medicine Blister Pack

What is pvc blister?

Pharmaceutical packaging has a layer of the most basic material is PVC,PVC bubble cover layer for pharmaceutical dosage form to provide structural rigidity and physical protection, prevent moisture oxygen into the bubble cover.The main advantages of PVC are its low cost and ease of thermal molding. In the case of blister packaging, PVC sheet material does not contain any plasticizer and is sometimes called rigid PVC or PVDC.

The thickness of PVC sheet is usually between 200µ and 300µ, depending on the cavity size and shape. Most PVC sheets used for medicinal blister covers are 250µ or 0.250 mm thick.

In order to overcome the lack of barrier performance of PVC film, it can be coated with PVDC or laminated PCTFE to increase the protection performance. Pvc-based multilayer blister films are commonly used in pharmaceutical blister packaging where PVC serves as a thermoforming framework for the structure. Better packaging of drugs.

Pharmaceutical Pvc Overview

Medicine pvc can be used to make tablets, capsules, and medicine packaging. It has a strong barrier to water, oxygen, and ultraviolet radiation, and then plays a role in protecting medicinal products. It is especially suitable for drugs with high sensitivity range and drugs with strong hygroscopicity or light-sensitive.

Pharma Pvdc Overview

PVDC is also a very popular and commonly used pharmaceutical packaging material, also known as PVC composite film. It is the most commonly used blister packaging material in pharmaceutical packaging. About 67% of blister packaging use PVDC composite film. PVDC composite film is a material with the best barrier properties and has an excellent barrier effect on air, moisture, and fine particles. It can be used under high temperature and high humidity conditions, and other properties are similar to PVD, such as good compatibility, ease to form and seal, and low price.

Pharma Alu Pvc/Pvdc Packaging Prospects

With the increase in the use of pharmaceutical products, the demand for aluminum/aluminum foil in the pharmaceutical industry is increasing, because the pharmaceutical packaging materials made of PVC/PVDC have the highest barrier to moisture, oxygen, other gases, and ultraviolet rays. Under ICH conditions It keeps the barrier performance under the lower part, and it ensures easy packaging due to its unique structure. Its tighter blister structure allows higher blister density to reduce blister size and material usage, saving costs.

PVC pharmaceutical packaging series composite sheet is mainly composed of PVC pharmaceutical sheet and another one or several new polymer material films and sheets, through extrusion, compounding, coating and other processing methods, it is another kind of pharmaceutical packaging that meets the requirements of pharmaceutical packaging. Novel combination of materials required.

Pvc pharmaceutical packaging combines the rigidity and good molding of PVC and the excellent barrier properties of PVDC to water vapor, oxygen, and CO2 odors. Packaging requirements for preserving fragrance. At the same time, it still uses the PTP aluminum-plastic packaging type, and the packaging equipment and process are exactly the same as the PVC pharmaceutical packaging materials. This series of composite materials can customize packaging materials for pharmaceutical factories according to the degree of moisture and oxidation of drugs, and become a higher-level PTP packaging type.

In addition, there are PVC/PE packaging materials instead of glass bottles to fill liquid and suppository drugs, which greatly improves the drug safety of this type of drugs.

PVDC is a high-barrier polymer material. The special physical properties of PVDC have attracted more and more attention, and are increasingly used in pharmaceutical packaging. These special physical properties include excellent barrier properties and chemical stability to oxygen, water vapor, carbon dioxide, and organic compounds. When more and more polymer materials are processed for pharmaceutical packaging, only PVDC has high barrier properties to water vapor and oxygen. Many polymer materials have inherently more barrier properties to water vapor, and coating a thin layer of PVDC on top of them will greatly enhance this performance.

In addition, PVDC coating can also isolate oxygen and other substances and keep fragrance. PVDC also has the properties of acid resistance, alkali resistance, fat resistance, solvent resistance, and drug resistance, making it more suitable for various types of pharmaceutical packaging, especially those that are easy to deliquesce, easy to oxidize, or contain chemically active substances and need to be protected. Pharmaceutical packaging that smells or absorbs odors.

What is the difference between pvc and pvdc

pvdc vs pvc

PVC has high mechanical strength, excellent electrical properties, acid and alkali resistance, and good chemical stability. Its disadvantage is the low thermal softening point. PVC is often used in decorative films and edge banding materials, and hard materials are used in various plates, pipes, profiled materials, doors and windows. Semi-rigid, foamed and composite materials are used for floors, ceilings, wallpapers, etc.

PVDC has the characteristics of flame resistance, corrosion resistance and good air tightness. Due to its strong polarity, it is insoluble in common solvents at room temperature. The disadvantage is poor light and thermal stability and difficult processing.

Pvc/Pvdc Aluminium Pharmaceutical Packaging Produce Guarantee

All medicinal packaging products (polyester/aluminum/polyethylene medicinal composite film) are produced in the purification workshop, and the PE bags used for product packaging are fully monitored by professional production personnel. A clean environment can maintain the same production cost while ensuring stable product quality.

Pvc/Pvdc Pharma Packaging Selection Considerations

The choice of packaging materials for medicinal packaging, the nature of the main medicines (moisture, oxidation, fragrance retention, etc.), and the shelf-life requirements are determined. It should be noted that this is a very prudent choice. It is necessary to consider both the quality of the drug and the development and cost of the company. It is recommended to determine the choice of packaging materials with a competent packaging material factory or packaging material experts. Huawei Aluminum is a company A supplier with more than ten years of aluminum foil manufacturing experience.

The basic principle of selection: general medicines, PVC medicinal tablets can be used if the requirements for moisture resistance are not high. PVC/PVDC or PVC/PE/PVDC composite sheets can be used for medicines that require moisture resistance and oxidation resistance or require a long shelf life. PVC/PE composite tablets can be used for oral liquid and suppository medicines.
