The most efficient packaging operations are often the most profitable. But even a well-run line can lose time, materials, and money through seemingly small issues that compound quickly across shifts, SKUs, and production cycles.
Here are five packaging line problems worth examining — and what the right packaging partner can do about them.
1. Startup Waste from Heat Sealing
Getting a heat-seal operation dialed in can take time. During startup, film may be lost while operators adjust temperature, pressure, and dwell time to achieve a reliable seal.
That waste may seem minor during a single production run, but multiplied across shifts, product changeover, and production days, it becomes a measurable cost.
The variables aren’t random. Sealant layer chemistry, operating window width, and film consistency all affect how quickly a line comes up to speed.
2. Downtime Caused by Improper Film Specifications
A film that looks right on paper can still create problems on the line. Coefficient of Friction (COF), machinability, and how a film tracks through equipment all affect whether a packaging line runs at its rated speed or runs at all.
When specifications don’t align with actual operating conditions, the result can be line stoppages, inconsistent seals, tracking failures, and production speeds that fall short of the equipment’s capability, impacting throughput, efficiency, and overall productivity.
3. Material Loss from Mismatched Structures
Not every packaging problem is about how a film runs – some are about what the film is. An over-engineered structure adds material cost and complexity without improving performance. An under-engineered one leads to package failures, damaged product, and scrap rates that erode margin at every stage.
The goal is to engineer the right structure for the product, equipment, the distribution environment, and shelf presentation, without adding unnecessary cost, material, or complexity.
4. Lead-Time Gaps
Even the most efficient packaging line cannot run without film. Forecasting issues, scheduling delays, demand spikes, or supplier lead times can create inventory pressure and interrupt production – putting customer commitments at risk.
5. Poor Supplier Communication
Many packaging line problems don’t start with the film itself. They begin when information stops moving quickly between the customer, sales team, pre-press, scheduling, engineering, and production.
A specification change, artwork revision, production concern, or forecast adjustment can cause a ripple effect throughout the entire supply chain.
The Solution: Look at the Entire Packaging System
Solving packaging problems requires looking beyond the roll of film. A structure that performs well in one application may create challenges in another due to differences in equipment, operating speeds, sealing conditions, product requirements, or distribution environments.
That is where Kendall Packaging’s engineering expertise can make a difference.
Our team works with customers to evaluate the entire packaging application — from film structure and sealant selection to equipment conditions, line speeds, graphics, production requirements, and distribution. By understanding how these factors work together, we can help identify potential problems before they become costly production issues.
For example, a wider heat-seal operating window may help reduce startup scrap and make a line less sensitive to normal process variation. Adjusting COF or film characteristics may improve tracking and machinability. In other applications, simplifying a structure may reduce material cost without sacrificing the performance the package requires.
“When we review a customer’s packaging operation, we’re not just looking at the film. We’re looking at how the film works with the equipment, the product, the production speeds, and the distribution environment,” said Trung Nguyen, Director of Technical and Quality. “Often, it isn’t one major problem that’s driving cost. It’s several smaller issues adding up over time. Identifying those opportunities before they become larger problems can make a meaningful difference.”
Kendall customers have a dedicated team aligned with their business. As a privately-held company, our structure allows our teams to make decisions and communicate changes without navigating multiple layers of approval. That responsiveness and communication is a practical and operational advantage – not just a claim, offering a level of flexibility and responsiveness that can be difficult to achieve in larger organizations.
Our teams work closely across sales, engineering, pre-press, scheduling, and production, helping ensure everyone understands the customer’s requirements and potential issues are addressed quickly.
That coordination becomes especially important for customers managing multiple brands, SKUs, production schedules, and changing market demands. Problems get caught earlier, decisions move faster, and the customer’s team spends less time managing supplier issues and more time focused on their operation.
Small Improvements Can Deliver Significant Results
Packaging line efficiency rarely improves by solving one enormous problem. More often, profitability improves by identifying and eliminating the smaller, recurring sources of waste, downtime, and daily disruption that gradually become accepted as the status quo.
The right packaging partner doesn’t just supply film. They help you understand where problems occur, determine why they happen, and find practical ways to improve the entire packaging process – before they impact the bottom line.
At Kendall Packaging, engineering expertise, responsive customer service, and close coordination across our teams are all part of helping customers keep their packaging lines and their businesses moving forward.
