TCG Board Game Sports Card Sleeves Manufacturing and Size Selection

Introduction to Card Sleeve Protection

1. The Manufacturing Process of Clear Card Sleeves

Clear card sleeves are the most basic yet essential protective layer for cards. Here’s how they’re made:

• Core Material: The process starts with PP (polypropylene) pellets, which are heated until they melt into a liquid.
• Production Steps:
  1. The liquid PP is blown into thin, flexible rolls through a specialized machine.
  2. These rolls are then precision-cut by an automatic slitter to create sleeves for specific card types, such as:
     • Inner sleeve.
     • Dual sleeve.
     • Outer sleeve
     • Rounded sleeves.
     • Self-adhesive sleeves.
• Key Feature: Transparent sleeves offer maximum clarity, allowing your cards’ artwork to shine while providing superior protection against scratches and dirt.

2. Solid-Color Card Sleeves

Solid color sleeves add a pop of color to your collection while maintaining protection. Their manufacturing process involves:

• Materials: CPP (cast polypropylene) pellets mixed with color pigments.
• Production Steps:
  1. The colored CPP mixture is melted and combined with a transparent layer through a three-layer co-extrusion process.
  2. The resulting roll is cut and welded to ensure the color layer doesn’t fade or peel.
• Advantage: These sleeves are ideal for hiding card backs in competitive play or adding a stylish touch to your collection.

3. Custom Printed Art Sleeves

For sleeves that truly stand out, custom printed sleeves are the way to go. Sanseking uses advanced techniques to bring designs to life:

• Design Process:
  1. Your artwork is separated into CMYK color channels and transferred onto printing plates.
  2. High-quality inks are applied to a composite material (e.g., CPP, OPP, or PVC-aluminum film) using a four-color printing press.
  3. The printed layer is bonded with a transparent layer and precision-cut to size.
• Popular Styles: From holographic accents to full-coverage artwork, printed sleeves allow you to showcase your unique style.

4. Quality Standards for Card Sleeves

At Sanseking, we adhere to rigorous quality control to ensure every sleeve meets the highest standards:

1. Precision Sizing: Size accuracy within 0.01mm to prevent slipping or tight-fitting.
2. Print Perfection: No misaligned borders or off-center designs in printed sleeves.
3. Material Purity: No visible specks or impurities in the plastic.
4. Opaque Layers: Competitive sleeves block light entirely to prevent card back visibility.
5. Clarity: Transparent sleeves must achieve 90% light transmittance.
6. Durability: Seams must withstand 13lb of tensile strength.
7. Smooth Insertion: Cards glide in and out without snagging.
8. Consistency: Batch-to-batch color matching with zero color variation.
9. Sleek Finish: No curled edges or uneven cuts.
10. Print Longevity: Vivid, scratch-resistant prints that won’t fade or peel.

Size Selection for Different Card Types

Choosing the right sleeve size is critical for optimal protection and functionality. Below is a detailed guide for TCG, board game, and sports trading cards.

1. TCG Card Sizes and Sleeve Recommendations

TCG cards come in various sizes, each tailored to specific games. Here’s how to match them with sleeves:

Pro Tip: Many players use a two-layer system—an inner sleeve for protection and an dual sleeve for style or tournament compliance.

Standard size (63.5 x 88 mm) is the most widely used TCG card size in the world, suitable for most popular TCG games.

Small size (59 x 86 mm) is mainly used for Japanese TCGs, such as "Yu-Gi-Oh".

Large size (70 x 120 mm) is usually used for Tarot cards or large special cards.

Square and small square cards are mostly used for specific board game designs and are not the standard of mainstream TCG.

Mini European Size and Oversize Cards are mainly used for special games.

2. Board Game Card Sizes

Board games often feature unique card sizes. Below are 30 common board game card dimensions and their recommended sleeve sizes:

Always measure your cards and choose sleeves that are 1–2mm larger for a secure fit.

3. Sports Trading Card Sizes

The size, thickness, issuing company, series and corresponding card film size of sports trading cards are topics that collectors are very concerned about. Below is our list of common sports trading card sizes, thickness, issuing companies and series, issuing years and recommended card sleeve sizes.

How to Choose the Right Card Sleeves

1. Understand Your Card’s Dimensions and Thickness:
   Ensure you know the exact size of your cards (e.g., standard 63.5 x 88 mm) and their thickness (35pt, 55pt, etc.). This precision is crucial for selecting sleeves that fit perfectly.
2. Select the Correct Sleeve Size:
   Card sleeves should typically be 1–2mm larger than the card itself. For example, a standard 63.5 x 88 mm card pairs best with a 64 x 89 mm sleeve, ensuring easy insertion without looseness.
3. Opt for Hard Cases for Rare or Thick Cards:
   High-value or thick cards (130pt+) require extra protection. Invest in rigid card holders to prevent bending, warping, or damage from external pressure.
4. Consider Thickened Sleeves for Added Durability:
   Cards thicker than 130pt benefit from ultra thick sleeves designed to accommodate their bulk while maintaining a secure fit. These sleeves offer superior protection against wear and tear.

By following these guidelines, you’ll ensure your sports cards, TCG cards, or board game cards stay in optimal condition, preserving their value for years to come.

Why Card Sleeves Matter: A Collector's Perspective

As avid collectors and enthusiasts, we understand that protecting your cards is paramount. Card sleeves are far more than just plastic covers—they’re the guardians of your collection’s integrity and long-term value. Below, we share our expertise on choosing and using sleeves effectively.

1. The Core Functions of Card Sleeves

Card sleeves serve multiple critical roles in preserving your cards:

• Water and Dust Resistance: They create a barrier against spills, humidity, and dust, keeping surfaces clean and damage-free.
• Scratch Protection: Sleeves shield cards from scratches, especially on vulnerable edges and corners.
• Wear Prevention: Frequent shuffling or handling can cause friction damage; sleeves reduce this wear significantly.
• Enhanced Handling: High-quality sleeves often feature a smooth texture that improves grip and shuffling ease.

2. Key Factors to Consider When Choosing Sleeves

• Perfect Size Match:
  Sleeves must fit snugly without being too tight. A loose sleeve can cause cards to slide, while a too-tight sleeve may bend the card. For standard 63.5 x 88 mm cards, a 64 x 89 mm sleeve is ideal.
• Thickness Selection:
  • Standard Thickness (35µm–100µm): Suitable for everyday cards, balancing protection and flexibility.
  • Heavy-Duty Thickness (100µm+): Essential for thick or valuable cards, often paired with hard cases for maximum security.
• Clarity and Smoothness:
  Transparent sleeves should offer 90%+ clarity to showcase card artwork vividly. A smooth surface ensures seamless shuffling and reduces friction.
• Antistatic Properties:
  Static-resistant sleeves prevent dust and debris from clinging to cards, keeping collections looking pristine during long-term storage.

3. Sleeve Strategies for Different Card Types

• Standard Cards (e.g., Magic: The Gathering, Pokémon TCG):
  Standard-sized sleeves (64 x 89 mm) provide reliable protection for daily use and tournaments.
• Rare or Limited-Edition Cards:
  Double-sleeve these treasures—start with a thin inner sleeve for cushioning, then add a premium outer sleeve or hard case for display and protection.
• Vintage or Fragile Cards:
  Opt for extra-thick sleeves or double-layer protection to safeguard delicate paper. These cards are often displayed rather than played with, so durability is key.
• Odd-Sized Cards (e.g., Tarot, Mini Cards):
  Use custom or specialty sleeves (e.g., 71 x 121 mm for tarot) to ensure full coverage and prevent damage.

4. Maintaining Your Card Sleeves

Even with sleeves, regular maintenance is essential:

• Replace Worn Sleeves: Scratched or torn sleeves can harm cards over time—swap them out promptly.
• Store Cards Properly: Keep cards in a cool, dry environment away from direct sunlight to prevent sleeve warping or card discoloration.
• Use Humidity-Controlled Storage: For high-value collections, invest in humidity-controlled cases to protect against moisture damage.
