1. Based on Material Type
(A) Plastic Blisters
PVC (Polyvinyl Chloride)
Common, cost-effective, and offers good clarity.
Used for pharmaceuticals and consumer goods.
Limited heat resistance; may require additives for flexibility.
PET (Polyethylene Terephthalate)
High clarity, strong, and resistant to moisture.
Used for premium packaging (e.g., electronics, high-end products).
Recyclable and food-safe.
PP (Polypropylene)
Good chemical resistance and durability.
Used for medical devices and industrial products.
Can withstand autoclaving (sterilization).
PE (Polyethylene)
Flexible and impact-resistant.
Used for non-rigid blister packs (e.g., caps, seals).
COC (Cyclic Olefin Copolymer)
High moisture barrier, excellent clarity.
Used in sensitive pharmaceutical packaging.
APET (Amorphous Polyethylene Terephthalate)
Clear, rigid, and recyclable.
Often used in clamshell packaging.
(B) Aluminum Blisters
Used for high-barrier protection (oxygen & moisture).
Common in pharmaceutical blister packs (e.g., tablets, capsules).
Can be combined with plastic films (Alu-Alu or Alu-PVC blisters).
(C) Paper-Based Blisters
Eco-friendly alternative, often coated for moisture resistance.
Used for lightweight consumer goods.
2. Based on Structure
Thermoformed Blisters – Made by heating and molding plastic sheets.
Cold-Formed Blisters – Aluminum-based, shaped without heat.
3. Based on Barrier Properties
High-Barrier Blisters (e.g., Alu-Alu, COC) – Protect against moisture/O₂.
Medium-Barrier Blisters (e.g., PVC/PVDC) – Moderate protection.
Low-Barrier Blisters (e.g., plain PVC) – Basic protection.
4. Based on Sealing Method
Heat-Sealed Blisters – Plastic-to-lidding material (e.g., foil, paper).
Adhesive-Sealed Blisters – Uses pressure-sensitive adhesives.
Applications
Pharmaceuticals (Alu-PVC, COC, Cold-form foil)
Electronics (PET, PP, anti-static options)
Consumer Goods (PVC, PET, paper-based)
Food Packaging (APET, RPET for sustainability)
