A blister packing machine is one of the most widely used packaging solutions in the pharmaceutical, food, and healthcare industries. It seals tablets, capsules, or small medical devices in PVC/AL or AL/AL cavities, ensuring product protection, hygiene, and shelf-life extension. This article provides a complete introduction to the structure, working principle, and core advantages of blister packaging.
A modern blister packing machine typically includes the following components:
Uses heating plates to soften PVC film.
Creates blister cavities using vacuum forming or pressure forming.
Feeds tablets or capsules into formed cavities.
Vibratory feeders and brush boxes ensure accurate filling.
Seals the formed PVC with aluminum foil (AL foil).
Guarantees airtight protection and uniform sealing quality.
Prints batch numbers, expiry dates, and production codes.
Cuts the sealed sheet into individual blister packs.
Blister packs are widely used in:
· Pharmaceutical tablets & capsules
· Nutritional supplements
· Chewing gums and small confectionery
· Small medical devices
· Hardware accessories (screws, clips, etc.)
Because blister packaging is secure, lightweight, and convenient for dosing, it is the preferred format for OTC and prescription medicines.
Provides reliable barrier properties for most drug types.
Transparent PVC allows customers to view the content clearly.
Allows “one blister at a time” dosing.
High-speed blister machines can produce hundreds of blisters per minute.
A blister packing machine is essential for pharmaceutical manufacturing lines due to its efficiency, hygiene, and strong protective properties. Whether you produce tablets, capsules, or nutraceuticals, blister packaging remains one of the most economical and reliable choices.
