In the canned foods industry, knowing how to form and evaluate a proper double seam is essential. This hermetic seal guarantees the quality, safety, and shelf life of your company’s product. So how can you ensure your team has the skills to consistently create, inspect, and maintain the double seams you need?

Enter Silgan University’s most popular course: Double Seam Evaluation. This foundational training program is in high demand because it offers proactive solutions for mitigating operational risks and helps standardize knowledge within your workplace.
In this article, we’ll explore why this training is crucial for industry professionals, what participating students can expect to learn, and which flexible training options are available for your team.
The Benefits of Silgan’s Double Seam Evaluation Course
Silgan’s Double Seam course addresses two critical pillars of the canned foods sector: maintaining product integrity and ensuring industry stability. Poorly constructed double seams can lead to product recalls, economic losses, troubleshooting delays, and unnecessary stress for your company and employees. Providing your team with double seam training can help you avoid potential issues down the line and improve manufacturing efficiency.
The best part? Silgan’s Double Seam Evaluation course is highly accessible. Whether you’re a mechanic, operator, quality assurance analyst, or corporate manager, this course provides standardized knowledge on double seams for anyone working in the beverage or food-can manufacturing and filling industry. Both listed versions of the Double Seam class, Technical (CTS) and Equipment (CES), provide the same content, delivered by subject matter experts who can answer your questions and offer industry insight.
What Will You Learn in Silgan’s Double Seam Course?
Silgan’s training program offers a comprehensive overview of double seams, from formation to final evaluation.
The course begins with a foundation of what a double seam is and expands to an in-depth review of double seam formation. The core of the class is dedicated to practical evaluation. With integrated video demonstrations, students can get a first-hand look at how to manually pull apart their seams to search for defects — honing in on the differences between external and internal malformations.
Silgan’s curriculum also encourages students to look beyond basic dimensions and view the double seam as a holistic structure. Course instructors will talk through how a seam can have acceptable physical dimensions but still be compromised. This shift in focus is vital for students, as it provides a full-picture understanding of seam formation and evaluation.
Silgan’s Flexible Training Options
Silgan University understands that every metal food packaging operation has unique scheduling needs and geographic constraints. To ensure your team receives the highest quality education without disrupting production, we offer several flexible options for attending our Double Seam Evaluation course. The course is also offered in French Canadian.
Onsite Training: Bringing Expertise to Your Floor
For many of our customers, the most effective way to learn is right where the work happens. Our traditional onsite training is conducted at your facility, often referencing your own equipment for a more tailored experience.
- Classroom Foundation: The core of the course is a comprehensive, lecture-based presentation that covers the “nuts and bolts” of seam formation and evaluation.
- Customized Focus: While the fundamental content remains consistent, instructors can pivot to focus on your specific plant needs — for example, focusing on beverage cans if they’re relevant to your operation.
- Hands-on Add-ons: For teams that need to go beyond the basics, we offer a “bolt-on” practical session. This allows students to perform a manual teardown exercise, physically pulling seams apart to evaluate dimensions and identify internal defects.
- Comprehensive Materials: All students receive high-quality training literature and textbooks (available in English, Spanish, nd Canadian French) to keep as a permanent reference on the floor.
Virtual Training: Worldwide Accessibility
To meet the growing demand for remote learning, Silgan now offers a quarterly virtual version of the Double Seam Evaluation course. This option is ideal for small groups, international teams, or corporate staff who need to understand the technical side of the business without traveling to a plant.
- Strategic Scheduling: These virtual sessions are coordinated on a quarterly basis — providing you with opportunities to attend training at a time that works best for your team. This allows “fresh pack” customers to train new hires before the busy season starts and year-round customers to easily schedule training for 2nd and 3rd shift employees.
- Curated Class Sizes: To maintain a high-quality learning environment and encourage student questions, we maintain a “soft cap” of approximately 30 students per session.
- Confidential Learning Environment: Our virtual platform is intentionally “blinded,” ensuring that the participant list and cameras remain private. This creates a secure space where students can speak freely and ask specific troubleshooting questions without disclosing sensitive company information.
- Competitive Value: Virtual training is offered at a flat, accessible rate of $75 per person, providing the same industry-leading curriculum as our onsite sessions without any added travel costs.
The Details: Efficient, Accessible, and Certified
Regardless of which format you choose, the Double Seam Evaluation course is designed to be a high-impact, low-commitment solution for your busy schedule.
- Two-Hour Window: The course lasts approximately two hours, making it easy to fit into a single shift.
- Language Accessibility: To support a diverse workforce, we have instructors who are fluent in Spanish and Canadian French, as well as translated materials available to ensure technical information is clear to every student.
- Standardized Certification: Upon successful completion, Silgan provides a certificate for every participant. While not a regulatory requirement, these certificates are a valuable way to track employee development.
