Blister Card Types Comparison Table

Style Selection

Choosing the right blister card style is key to balancing presentation, security, and budget. Consider the following:

1. Product Weight and Fragility

• Lightweight items: Face seal or insert cards are sufficient.
• Heavy or fragile items: Opt for trapped blisters, fold-over, or clamshell styles for added security.

2. Display Preference

• High visibility: Full face seal, mock clamshell, and clamshell packaging provide maximum product view.
• Premium branding: Use full face seal or trapped blisters with extensive printing area for instructions and graphics.

3. Tamper Resistance Needs

• Standard security: Face seal or single-seal cards.
• High tamper evidence: Trapped or double-trapped blisters, clamshells, or fold-over designs.

4. Retail Display Requirements

• Pegboard or hanging displays: Standard cards with pre-punched hang holes.
• Shelf or self-standing: Footed blisters or mock clamshells with pedestals.

5. Specialty/Custom Shapes

• Mock clamshells and custom die-cut trapped blisters help match unique product forms or branding elements.

Size Tips

Getting the correct dimensions is crucial for effective blister card packaging.

1. Measure Product Accurately
2. Use vernier calipers or precise rulers to measure length, width, and height.

3. Confirm odd dimensions (protrusions, curves, pointy parts).

4. Blister Cavity Sizing

5. Ensure a snug fit to prevent product movement inside the blister.

6. Avoid tight fits that cause stress on fragile products.

7. Card Size

8. Allow ¼–½ inch margin around the blister for seal integrity and aesthetics.

9. Standard retail cards range from 4 x 5 inches to 6 x 9 inches, but custom sizes are available.

10. Billboard Space

11. Factor in branding, instructions, barcodes, and regulatory info.

12. Use both front and back sides or fold-over designs for more print area.

13. Retail Fixture Compatibility

14. Verify hang hole placement and overall dimensions for your intended retail fixture (pegboard, hooks, shelves).

Material Comfort

Choosing optimal materials ensures your packaging is protective, visually appealing, and eco-conscious.

1. Plastic Blister Materials

• PVC (Polyvinyl Chloride):
• Widely used for clarity and affordability.
• Heat-seals well to coated cards.

• Less eco-friendly; recycling options limited.

• PET/PETG (Polyethylene Terephthalate/Glycol-Modified):

• Crystal-clear visibility, excellent impact resistance.
• More recyclable and food/pharma safe variants exist.

• May need specialized heat-seal coatings.

• Polystyrene:

• Good rigidity, slightly less clear.
• Used for certain applications needing shape retention.

2. Cardboard/Paperboard Options

• SBS (Solid Bleached Sulfate):
• Premium, smooth, bright white surface for high-quality printing.
• Usually 14pt, 18pt, or 20pt thickness.
• C1S/C2S (Coated One/Two Sides):
• Glossy or semi-gloss finish enhances visual appeal.

• Choose C2S if both sides will be visible.

• Eco/Alternative Boards:

• Grass paper, recycled fibers, or FSC® certified boards available.
• Offers sustainable branding opportunities.

3. Coatings and Adhesives

• Heat-Seal Coatings:
• Aqueous (water-based) and solvent-based formulas activate during sealing.

• Match coating to plastic type for best adhesion (different for PVC, PET, etc.).

• Specialty Coatings:

• Cold-seal and pressure-sensitive options for eco or specialty requirements.
• Tear-, moisture-, or UV-resistant coatings available.

Outfit Matching (Branding & Visual Cohesiveness)

Blister card packaging is a versatile marketing tool:

• Branding: Use consistent color schemes, logos, font types, and design motifs across your packaging line.
• Product lines: Match card backgrounds, blister shapes, and print finishes to create “family” appeal and instant recognition.
• Visual Impact: High-gloss or matte finishes, metallic inks, embossing, or spot UV can boost shelf impact. Always test color fidelity and print proof samples.
• Regulatory Compliance: Ensure necessary legal info (warnings, barcodes, certifications) is incorporated without compromising design.

Seasonal Recommendations

Optimize your blister card approach for different times of year and special campaigns:

• Holiday Gift Packs: Use promotional fold-over or double-trapped blisters for enhanced graphics and gifting appeal.
• Back-to-School, Tool Season, etc.: Create limited edition cards with school themes or tool tips to boost impulse buys.
• Summer/Winter Products: Use weather-resistant coatings or tear-resistant cards for outdoor or seasonal products.
• Sustainable Gifting: Offer all-paper or recycled blister cards for eco-conscious holiday and Earth Day promotions.
• Specialty Finishes: Consider adding QR codes or interactive elements for seasonal marketing campaigns.

Practical Tips and Best Practices for Choosing and Using Blister Cards

1. Define Your Product Needs

2. Weight, fragility, shape, and retail environment determine the right style and materials.

3. Prioritize Security

4. For high-value or easily pilfered items, invest in tamper-evident designs.

5. Balance Cost and Features

6. Face seal cards are budget-friendly; premium trapping or clamshell styles add cost but boost protection and perceived value.

7. Focus on Print Quality

8. High-resolution graphics and color-matching enhance shelf appeal and brand recognition.

9. Consider Environmental Impact

10. Choose recyclable plastics, FSC-certified boards, or all-paper solutions where possible.

11. Test Prototypes

12. Conduct drop, seal, and opening tests before mass production to ensure usability and durability.

13. Retailer and Logistics Compatibility

14. Ensure packaging fits store fixtures, shipping cases, and meets retailer requirements (like anti-theft features).

15. Order Quantities and Combo Runs

16. Leverage combo-run suppliers if you need small to medium batch sizes while keeping costs down.

17. Check Regulatory and Industry Standards

18. Particularly crucial for pharmaceuticals, electronics, and children’s toys.

1. Keep User Experience in Mind
   • Make opening straightforward without damaging the product; include clear instructions if necessary.

FAQ

What is a blister card?
A blister card is a type of packaging where a clear, molded plastic cavity (the blister) is heat-sealed or glued to a printed paperboard card. This package holds, displays, and protects retail products while allowing for branding and instructions on the card.

How do I choose the right blister card style for my product?
Consider your product’s size, weight, fragility, and security needs. Use face seal for basic items, trapped blisters for heavier or premium products, fold-over for larger branding areas, and clamshells for maximum protection.

What are the main material options for blister cards?
Most blisters are made from PVC or PET for clarity and durability. The backing card is usually solid bleached sulfate (SBS) paperboard, often with a gloss or matte coating for visual appeal. Eco-friendly options like recycled board or all-paper blisters are also available.

Can blister cards be recycled?
In many cases, yes—paperboard cards are recyclable, and PET blisters are widely accepted where facilities exist. However, PVC is less widely recycled. All-paper options offer the easiest recyclability.

What advantages do blister cards provide?
They offer clear product visibility, tamper resistance, security, space for branding, cost-effective packaging, and improved retail shelf appeal.

Are there eco-friendly blister card options?
Yes. Options include all-paper blisters, boards with recycled content, or using PET instead of PVC for the plastic component. Some suppliers also offer water-based heat-seal coatings.

What is the difference between face seal, full face seal, and trapped blister cards?
A face seal blisters to just the front card edge; full face seal covers the whole card; trapped includes the blister sandwiched between two cards. Each step up offers increased protection and tamper resistance.

How many colors can be printed on a blister card?
Most suppliers offer up to four-color (CMYK) printing with options for spot colors and specialty finishes like UV, metallic, or embossed accents—ensuring reliable color and crisp graphics.

Are custom sizes or shapes possible with blister cards?
Absolutely. Blisters can be custom-molded to fit almost any product. Cards are die-cut to nearly any size or shape, and features like hang holes, rounded corners, and tear notches are common.

What factors influence blister card costs?
Material thickness, type of plastic, card stock, complexity of printing, size of the card, style (single, trapped, fold-over), order quantity, and add-ons like specialty finishes all impact the total price. Combo-run and bulk orders help reduce costs.
