How can-seam materials impact TPO 

Who can resist a breath of fresh mountain air? While oxygen benefits your body and mind, it’s not a canner’s best friend. In fact, total package oxygen (TPO) can affect both your canning materials and your machines. In this blog post, we’ll explore how can-seam materials can impact your total package oxygen levels and what you can do about it.  

But first:

What is total package oxygen?

At RSS MACLIN, we support everyone in the food and beverage packaging industry, from micro-breweries to carbonated beverage giants. For those new to the industry, total package oxygen is the amount of oxygen that is sealed in a package. For cans, this includes: 

  • Dissolved oxygen: The oxygen that is dissolved in the liquid itself 
  • Headspace oxygen: The oxygen within the foam of a carbonated beverage 
  • Oxygen transmission: Oxygen that slowly permeates through the walls of the can 

At RSS MACLIN, we’re committed to excellence. 

How do can-seam materials affect TPO levels?

The materials used for can seaming are important to ensure low TPO and a high-quality seal. When exploring how can-seam materials affect TPO, we’ll look specifically at the compound, can body, and seam specifications.  


Compound quality and consistency  

When you’re trying to ensure a quality seam on your can, compound is crucial. It’s a vital part of the sealing process and ensures an airtight and secure seam with low TPO levels. Be sure to check the consistency of the compound to ensure optimal quality, since that can also impact the quality of the seam and the TPO levels.  

Compound amount 

In addition to the quality of the compound, it’s also important to ensure the right amount of compound is applied to each lid. For the best results, apply 26-32 grams of compound, depending on the diameter of the lid.  

Can body  


In the food and beverage packaging industry, aluminum is the material of choice, often selected for its corrosion resistance and lightweight properties. Over time, aluminum cans are susceptible to oxygen transmission, where the oxygen passes through the material and into the can’s liquid, increasing the TPO levels. For this reason, it’s important to use materials that are new, as the age of the material can impact the TPO levels. At RSS MACLIN, we recommend using lids that are no more than 2 years old, so as not to compromise the quality of the seal.

Can dimensions  

At RSS MACLIN, we know that details matter. When you ask for scheduled or emergency service, we look at more than just the equipment. Your can’s dimensions are crucial to accurately determine the pin height so that the can seam is shaped and sealed correctly. To calculate the pin height, use the following equation:  

Pin height = Raw can height – Chuck lip height – Material loss – Material deflection 

Seam specifications  

Curl height  

The can seam’s curl height can help minimize TPO levels and improve the quality and integrity of the seal. While curl height varies according to the can’s dimensions, it’s important that seam technicians regularly inspect the seam quality and adjust as necessary.  

Flange angle 

As a critical aspect of the seam, the flange angle provides strength to ensure that the seam is able to withstand the internal pressure of carbonated beverages without compromising the seal. If the flange angle isn’t correct, the seam could leak, leading to increased TPO, decreased freshness, and possible product contamination.

Take your can seams to the next level

Don’t let inconsistent canseam quality hold you back. Sign your team up for our hands-on canseaming training to learn how to inspect, identify, and correct issues to ensure ultimate product freshness and customer satisfaction.

5 Reasons Why Routine Machine Audits Are Crucial to Prevent Emergencies

August 7, 2023

RSS Maclin

With 75 years of can seaming experience, we understand the ramifications and cost of downtime in manufacturing. In this blog post, we’ll explore 5 reasons why routine machine audits are crucial to prevent emergency downtime, and what you can do instead. 

But first things, first:

Do you have a can-seamer emergency?

When your can seamers are down, contact RSS MACLIN. We’ll respond within 24 hours, so that you can get your production line up and running.  

But even when things are running smoothly, you don’t want to leave production to chance.

It can be challenging to control all of your can seamer processes so closely that you prevent all downtime, but that doesn’t mean that you have to plan production schedules to accommodate for unplanned production downtime.

When you schedule a routine machine audit with RSS MACLIN, we’ll help you to:

1. Avoid production downtime 

When cans are being sealed as fast as 70,000 cans per hour, time is money. Every minute of downtime counts, when you’re trying to fulfill a customer demand by a certain deadline.  

When your can seamer production is down, it’s easy to calculate the lost profit, but read one, and you’ll uncover some of the hidden costs.  

2. Avoid labor downtime 

Operators who are standing by during a can-seamer emergency are costing the company money, adding to the unexpected cost from lost production. Even when the unexpected happens, can-seamer training can help reduce your production downtime and help your line return to peak O.E.E.  

3. Avoid ingredient and material loss 

When your product line stops, it impacts your ingredients and materials. They can spoil or become contaminated. Sometimes, when the seaming process comes to a halt mid- production, defects in the can seam require the product to be thrown out.  

When you schedule a routine machine audit with RSS MACLIN, we can ensure that ingredient and material loss from unplanned can-seamer emergencies are kept to a minimum.  

4. Avoid production scheduling conflicts  

Production scheduling can turn into a nightmare when the line stops. It affects nearly every product line deadline. But plant managers don’t have to schedule to accommodate for unplanned can-seamer emergencies. Instead, a simple routine can-seamer machine audit can help keep the line flowing and the schedule on target.  

5. Avoid supply chain problems 

With so many companies relying on “just in time” inventory management practices, companies receive the exact amount of material, almost exactly when they need it. But problems arise when production lines aren’t humming. This can happen to both the receiving and the delivery end. It can result in too much raw material waiting to be used, and too many empty delivery trucks waiting to be dispatched. 

What does a routine can-seamer machine audit consist of?

At RSS MACLIN, our audit services include both diagnosis and repair of your can-seaming machinery. We’ll make the most of your scheduled downtime to address all of the parts along your production line (not just the can seamer), to ensure that your can-seaming production keeps running at peak O.E.E.

Understanding the lubrication system components enables efficient maintenance. Diagnosing each assembly separately facilitates faster diagnostics and repairs, minimizing downtime. To ensure the longevity of your machine, it is crucial to implement routine oil changes as recommended by the original equipment manufacturer (OEM). By adhering to the recommended oil change intervals and selecting the right viscosity grade, you can maximize the efficiency and durability of your equipment.   

Optimize Machine Settings:  

To achieve optimal performance, it is essential to calibrate the setup of each can seamer according to its specific requirements. Invest time in understanding your machine’s capabilities thoroughly. Regularly monitor and adjust settings such as seam thickness, seaming speed, and seam quality as needed. Fine-tuning these parameters can greatly enhance the efficiency of your can seamer, resulting in consistent and reliable sealing of cans. This attention to detail ensures high-quality seams and maintains the integrity of the can bodies. 

Train and Empower Staff:  

Maximizing can seamer efficiency relies on the expertise and empowerment of can-seam operators and technicians. It is crucial to invest in comprehensive training programs to ensure a deep understanding of the machine’s functionalities, safety protocols, and troubleshooting techniques. By encouraging your team to take ownership of their work and involving them in the optimization process, you tap into their valuable expertise and experience. By empowering can seam operators, they gain the ability to be self-reliant, taking charge of self-diagnosing issues and refining processes. As the “first responders” before technicians step in, operators play a crucial role in promptly identifying areas for improvement and boosting overall efficiency. This proactive approach ensures that the production line doesn’t suffer setbacks due to employee turnover, as operators and technicians are equipped to handle challenges and maintain operations smoothly.

 Quality Control and Inspection:  

To ensure the production of defect-free cans, it is essential to implement a robust quality control and inspection system. This system should diligently detect any abnormalities or defects in the seaming process, preventing the occurrence of hold-products. The can manufacturer’s specification sheet will provide recommended measurements for properly sealed cans, serving as a valuable reference. 

Regular inspections of the seams are crucial to identify any signs of improper sealing, such as leaks or loose ends. To enhance the inspection process, leverage advanced technologies like seam vision systems, which offer precise and speedy defect identification. By proactively catching and addressing issues at an early stage, you can minimize waste, guarantee product integrity, and uphold high efficiency throughout your can-seaming operation. 

It is worth noting that seam analysis is often overlooked or underutilized. To address this, ensure that multiple individuals are trained in seam analysis techniques. This allows for broader team involvement and ensures that seam analysis is performed consistently and effectively. By prioritizing comprehensive seam analysis, you can further enhance the quality control process and achieve superior results in your can-seaming operation. 

Continuous Improvement and Data Analysis:  

Embrace a culture of continuous improvement and leverage data analysis to optimize your can seamer’s efficiency.
