Material composition and characteristics of pure white opaque PVC coated PVDC high barrier drug blister packaging
PVC substrate: polyvinyl chloride (PVC) has good molding properties, is easy to process into blister packaging of various shapes, and is relatively cheap, which can provide certain strength and stability for the packaging.
PVDC coating: polyvinylidene chloride (PVDC) has extremely high barrier properties, with high molecular density, regular structure, and high crystallinity. It has an effective barrier effect on water vapor, oxygen, odor, and grease, which can significantly improve the moisture-proof and oxygen-proof properties of the packaging and extend the shelf life of the drug.
Color and transparency: The pure white opaque design can, on the one hand, play a shading role to prevent the drug from being deteriorated by light exposure, and on the other hand, make the packaging simple and beautiful, which meets the standardization and professional requirements of drug packaging.
Performance advantages
High barrier properties: It has excellent barrier properties against water vapor and oxygen, which is 10 times higher than that of pure PVC materials in terms of oxygen barrier properties and 5-10 times higher in terms of water vapor barrier properties. It can effectively prevent drugs from getting damp and oxidized, and maintain the stability and effectiveness of drugs.
Good blister performance: PVC/PVDC materials have good blister performance. Through the blister molding process, they can accurately shape a packaging cavity that matches the shape of the drug, tightly wrap the drug, and play a good role in fixing and protecting it.
Chemical stability: PVDC is chemically resistant and has good tolerance to most common solvents, organic acids, weak bases, alcohol, fruit acids, preservatives and other chemicals. It will not react chemically with drugs, ensuring the quality and safety of drugs.
Good sealing performance: The lid of the blister packaging can effectively block the entry of air and moisture, further enhancing the protective performance, and can almost completely isolate water vapor, oxygen, ultraviolet rays, etc. before the drug is taken.
High mechanical strength: This packaging material has good impact and pressure resistance, can withstand large external pressure and impact force, is not easy to be damaged during transportation and storage, and protects the medicine from being squeezed and broken by external force.
Processing technology
First, select a PVC hard sheet of suitable thickness and quality as the substrate and perform surface treatment on it to improve the surface adhesion.
Then, apply a water-based adhesive on the PVC hard sheet, and dry and solidify the adhesive by means of hot air evaporation of the solvent.
Next, apply PVDC emulsion or solution multiple times, and dry it after each application to make PVDC evenly adhere to the PVC substrate to form a multi-layer composite hard sheet.
Finally, the composite PVC/PVDC hard sheet is made into a blister package with a specific cavity according to the shape and size of the medicine through a vacuum blister molding process, and then the medicine is filled into the cavity and heated and bonded with the aluminum foil coated with adhesive to form an independent sealed package.
Application fields
It is mainly used in the pharmaceutical field and is suitable for the packaging of solid medicines such as capsules, tablets, and pills. It can provide reliable protection for medicines and ensure the quality and efficacy of medicines within the validity period.
Market prospects
With the continuous development of the pharmaceutical industry and the increasing requirements for drug quality and safety, the demand for high-barrier pharmaceutical packaging materials continues to grow. Pure white opaque PVC coated PVDC high-barrier pharmaceutical blister packaging has broad application prospects in the pharmaceutical packaging market with its excellent performance and good cost-effectiveness. It will gradually replace some traditional pharmaceutical packaging materials and become one of the mainstream choices for pharmaceutical packaging.
