What is a Blister Pack for Medications?
A blister pack is a type of pre-formed packaging that consists of a cavity or pocket made from a formable plastic, aluminum, or other materials, sealed with a backing such as aluminum foil or paper. It is widely used for pharmaceutical tablets, capsules, and other solid dosage forms to ensure product protection, patient compliance, and extended shelf life.
Why Are Blister Packs Used for Medications?
Blister packaging provides several benefits for pharmaceuticals, including:
✔ Protection – Shields medication from moisture, light, and contamination.
✔ Tamper Resistance – Ensures safety by showing signs of tampering.
✔ Dosage Control – Helps patients take the correct dosage at the right time.
✔ Extended Shelf Life – Enhances the stability of the medication.
✔ Easy Identification – Allows printing of expiration dates, dosage instructions, and branding.
Types of Blister Packs for Medications
How Are Blister Packs Manufactured?
1. Material Selection – Choosing the right plastic (PVC, PVDC, PET) or aluminum foil for the cavity and backing.
2. Forming Process – Thermoforming (heat) or cold forming (pressure) shapes the blister pockets.
3. Filling & Sealing – Tablets or capsules are automatically placed into cavities, then sealed with aluminum foil.
4. Cutting & Printing – Packs are cut into individual units, with branding, batch numbers, and expiry dates printed.
5. Final Packaging – Blister packs are boxed and prepared for distribution.
Blister Packaging vs. Bottles: Which is Better?
Best Choice?
· Blister Packs are ideal for prescription and OTC medications requiring protection and precise dosing.
