And various solutions and innovations in the security industry to help safeguard assets and prevent tampering. Companies like Cambridge Security Seals and TydenBrooks are leading the way in providing high-quality, reliable security seals used across multiple industries. Their products ensure the integrity of shipments, storage, and sensitive materials, offering unparalleled peace of mind for businesses and individuals alike. 

What Are Plastic Security Seals?

Types of Plastic Security Seals

Plastic security seals are designed to enhance tamper evidence and tamper resistance. They are available in various types to serve specific industries and needs:

  • Indicative Seals: Lightweight seals are often used for low-security applications like utility meters.
  • Security Seals: Stronger options for moderate security needs, ideal for logistics.
  • High-Security Seals: These meet stringent regulations like ISO 17712, often used for cargo shipments and customs compliance.

Common Materials Used

Plastic security seals are made from durable polymers, including:

  • Acrylonitrile Butadiene Styrene (ABS)
  • Polyamide (PA)
  • Polypropylene (PP) 

These materials are chosen for their strength, durability, and compatibility with modern technologies such as laser marking.

Applications Across Industries

Plastic seals find use across multiple industries:

  • Logistics: Securing containers and cargo during shipping.
  • Pharmaceuticals: Protecting medication from contamination and counterfeiting.
  • Food Services: Ensuring product integrity and compliance with health standards.
  • Retail: Securing high-value merchandise and returns.

Why Laser Marking?

The Laser Marking Process

Laser marking uses focused light beams to precisely engrave surfaces. This process integrates seamlessly with materials like ABS and PP, making it ideal for labeling plastic security seals with critical information such as serial numbers, barcodes, and logos.

Advantages of Laser Marking

  1. Precision and Permanence - Laser marking offers unmatched accuracy, producing detailed and indelible designs that withstand harsh environments, including exposure to chemicals and extreme temperatures.
  2. Enhanced Security - Laser markings are nearly impossible to alter, making them a robust solution against counterfeiting and tampering.
  3. Eco-Friendly Solution - Unlike traditional printing methods, laser marking eliminates the need for consumables like ink, reducing waste and environmental impact.
  4. Scalability - Laser marking is automated and fast, increasing production throughput for large-scale manufacturing needs.

The Role of Laser Marking Additives in Enhancing Performance

Laser marking alone isn’t enough to deliver optimal results on all plastics. Laser marking additives bridge the gap by enhancing the interaction between the laser and the plastic substrate.

What Are Laser Marking Additives?

Laser marking additives are specialized compounds added to polymers during production. They ensure the laser produces clear, high-contrast markings while improving speed and efficiency.

Benefits of Using Laser Marking Additives

1. Superior Marking Quality 

Additives ensure markings are sharp and readable, even for intricate designs like barcodes or QR codes. Additives like Lazact Black-C32W offered by Brilliance Laser Inks enable deep blacks on light-colored plastics or crisp whites on darker polymers.

2. Time and Cost Efficiency 

With optimized interaction between the laser and plastic, additives speed up the marking process without sacrificing quality. By enabling faster marking speeds, additives increase throughput while reducing production costs.

3. Improved Security

High-contrast, permanent markings deter counterfeiting and tampering, bolstering trust in your products.

4. Versatility 

Laser marking additives adapt to various laser systems and plastics, making them suitable for numerous applications.

Choosing the Right Laser Marking Additive

Selecting the right additive depends on several factors:

  • Plastic Type - Ensure compatibility with your material (e.g., ABS, PA, PP).
  • Laser System - Match the additive to your specific laser setup, whether UV or fiber-based.
  • Testing and Validation - Always test samples to validate marking quality and production efficiency.

Partnering with trusted suppliers like Brilliance Laser Inks ensures access to high-quality additives backed by industry expertise.
