core sticker Interview Questions and Answers

1. What is a core sticker?

   • Answer: A core sticker is a sticker that is applied to a product's core or central component, often for identification, authentication, or warranty purposes. It's designed to be difficult to remove or tamper with.

2. What are the different types of core stickers?

   • Answer: Core stickers can vary by adhesive strength, material (vinyl, polyester, etc.), size, shape, and printing methods (digital, screen printing, etc.). Some are destructible, leaving residue or tearing upon removal, while others are more easily removable.

3. What are the applications of core stickers?

   • Answer: Core stickers are used in various industries, including electronics, automotive, medical devices, and high-value goods, to prevent counterfeiting, track product authenticity, and provide warranty information.

4. How are core stickers different from regular stickers?

   • Answer: Core stickers are typically more durable, tamper-evident, and designed for more demanding applications than standard stickers. They often employ stronger adhesives and specialized materials.

5. What are some materials used in core sticker production?

   • Answer: Common materials include vinyl, polyester, polypropylene, and other specialized films chosen for their durability, resistance to environmental factors, and adhesive properties.

6. What are the advantages of using tamper-evident core stickers?

   • Answer: Tamper-evident stickers deter unauthorized access and modification, providing visual evidence of tampering and helping protect against counterfeiting and fraud.

7. How is the adhesive strength of a core sticker determined?

   • Answer: Adhesive strength is determined by the type of adhesive used and the manufacturing process. Testing methods include peel adhesion tests and shear adhesion tests to measure the force required to remove the sticker.

8. What are some printing methods used for core stickers?

   • Answer: Common printing methods include screen printing, digital printing, and flexographic printing, each offering different advantages in terms of cost, quality, and print volume.

9. How are core stickers applied?

   • Answer: Application methods can range from manual application to automated high-speed dispensing systems, depending on the volume and type of product.

10. What factors influence the cost of core stickers?

    • Answer: Cost is affected by factors such as material choice, size, quantity, printing complexity, adhesive type, and any special features (e.g., tamper evidence).

11. How do I choose the right core sticker for my application?

    • Answer: Consider the substrate you're applying it to, the environment the sticker will be exposed to, the level of tamper evidence needed, the required durability, and your budget.

12. What are some common problems encountered with core stickers?

    • Answer: Issues can include improper adhesion, premature detachment, printing defects, and difficulty in removal (if not designed to be easily removed).

13. How can I ensure the quality of core stickers?

    • Answer: Work with a reputable manufacturer, specify your requirements clearly, request samples and testing, and inspect the stickers upon delivery.

14. What is the role of a core sticker in preventing counterfeiting?

    • Answer: Core stickers act as a deterrent against counterfeiting by making it more difficult to replicate the product and its packaging, and by providing a visible indication of tampering.

15. How can I make my core stickers more secure against counterfeiting?

    • Answer: Incorporate unique serial numbers, use special inks or materials, utilize holograms, and consider microprinting or other covert security features.

16. What is the shelf life of a core sticker?

    • Answer: The shelf life depends on the materials used and storage conditions. Proper storage in a cool, dry place can extend the shelf life significantly.

17. What are some environmental considerations for core sticker production?

    • Answer: Consider using eco-friendly materials, minimizing waste during production, and choosing printing methods with lower environmental impact.

18. What are the benefits of using a destructible core sticker?

    • Answer: Destructible stickers provide clear evidence of tampering, making them ideal for high-security applications where authentication is critical.

19. What is the difference between a void sticker and a destructible sticker?

    • Answer: Both are tamper-evident, but void stickers reveal "VOID" lettering when removed, while destructible stickers may tear or leave residue.
