Material Options

Conductive carrier tape is typically manufactured from thermoplastic materials such as PS (Polystyrene), PC (Polycarbonate), PET, or ABS combined with conductive additives.

These materials allow the tape to maintain stable pocket structures while providing conductive properties required for electrostatic protection.

Cover tape is usually manufactured from PET film with adhesive or heat-seal layers. The cover tape is designed to seal the pockets of the carrier tape securely while allowing controlled peel strength during SMT feeding.

Material selection may vary depending on component sensitivity, sealing method, and production requirements.

Packaging Structure

In tape and reel packaging, electronic components are first placed into the pockets of the conductive carrier tape.
The cover tape is then applied to seal the pockets and hold the components securely in place.
After sealing, the tape is wound onto plastic reels, forming a continuous packaging format suitable for transportation, storage, and automated SMT feeding.
This structure helps maintain component orientation and prevents components from moving or falling out during handling.

One-Stop Customization of Multiple Materials

1. PVC Blister

High-toughness, non-flammable, soft PVC sheet. Customizable (transparent, colored, anti-static, gold-plated, flocked) with strong impact resistance and easy forming. Widely used for toys, food, electronics, cosmetics, etc.

2. PET Blister

Rigid, high-strength, food-grade safe PET with glossy surface. Customizable colors, ideal for export and eco-sensitive packaging. Not suitable for hot pressing or high-frequency welding.

3. PP Blister

Semi-translucent frosted PP with good toughness, anti-static/conductive properties, and heat resistance (≈120°C). Eco-friendly, non-toxic, microwave-safe; preferred for food and precision electronics packaging.

4. PS Blister

Lightweight, eco-friendly PS with high plasticity but brittleness. Excellent anti-static/conductive performance, mainly for blister trays. Not recyclable due to brittleness.

Frequently Asked Questions

Q: What is the function of carrier tape and cover tape in tape and reel packaging?

A: Carrier tape holds the electronic components in formed pockets, while cover tape seals the pockets to keep the components securely positioned during transportation and automated SMT assembly.

Q: What materials are used for cover tape?

A: Cover tape is typically made from PET film combined with adhesive or heat-seal layers that allow it to seal carrier tape pockets while maintaining controlled peel strength during SMT feeding.

Q: Why is peel strength important for cover tape?

A: Proper peel strength ensures that the cover tape securely seals the components during transportation but can be removed smoothly by SMT machines during automated feeding.

Q: What is the difference between conductive and antistatic carrier tape?

A: Antistatic carrier tape helps reduce static buildup, while conductive carrier tape allows electrical charges to dissipate more rapidly, providing stronger ESD protection for sensitive semiconductor components.

Q: Is conductive carrier tape and cover tape packaging compatible with SMT machines?

A: Yes. Tape and reel packaging systems are designed according to EIA-481 standards, ensuring compatibility with automated SMT pick-and-place equipment.
