Customizing Flow Wrappers for Unique Food Products
November 2025
In today’s competitive food market, differentiation isn’t just about the flavor or ingredients; it’s also about how a product is presented, preserved, and delivered. Flow wrappers (horizontal flow wrap machines) are workhorses in automated packaging lines. But when “unique” food products like odd shapes, delicate textures, or high moisture come into play, standard flow wrappers often fall short. That’s where customization matters. In this post, we’ll explore how Omori helps manufacturers tailor flow wrappers so that even the most challenging food products are packaged efficiently, safely, and attractively.
Why Customization Matters for Flow Wrap Machines
Consider these facts: Food and beverages remain the largest end-use segment in the flow wrap market, both globally, and in the U.S. Expectations are that revenue will rise from its 2024 level of $3.47 billion to $5.47 billion by 2030.
This growing demand puts increasing pressure on flow wrappers. Throw in unique items, such as fragile pastries or specialty cheeses, and the challenges mount. If your flow wrapper machine can’t keep up, you risk product damage, waste, client complaints, decreased throughput, and more. Ultimately, you could be falling behind in a market that has to speed up.
How Omori Customizes Flow Wrappers to Address Product Packaging Challenges
It comes down to expertise and experience. Omori’s experience lies in understanding the interplay of machine mechanics, materials, and product characteristics:
- Deep experience with both standard and non‐standard product formats, across bakery, confectionery, snacks, frozen foods, proteins, and more. Omori has seen many edge-case products, giving insight into what works and what needs special treatment.
- Strong engineering in forming systems, seal design, and feedback control. Omori understands the trade-offs between speed, seal integrity, and product integrity.
- Capability to support both flow wrap machine hardware customization (formers, feeders, sealing systems) and matching consumables (film trays, pads, film types), ensuring that the consumable side isn’t an afterthought.
- Focus on hygiene, cleanability, and design for food safety. Especially relevant for unique food types (moist, high‐fat, high perishability).
- Good service and support network, which means when a buyer customizes a flow wrapper for special products, the follow-through (maintenance, adjustments, parts) is solid.
Omori Expertise in Practice
Here are the areas Omori evaluates when customizing flow wrapping machines for unique food products. Scroll horizontally for full details.
| Customization Area | What’s Involved | Why It Makes a Difference |
| Former design (tube former, forming box, fin/wheel configuration) | Size, angle, surface finish, precision of forming elements that shape film around product; custom formers tailored to product cross‐section. | Ensures even film wrapping, reduces wrinkles, avoids film damage or scoring, helps maintain seal alignment. For odd shapes, custom formers can reduce wasted film and improve seal integrity. |
| Sealing technology | Options include hot vs cold sealing; heat sealing jaws vs rotary seals vs impulse vs ultrasonic; dwell time & temperature control. | Allows accommodation of films that are thicker, laminated, or sensitive (e.g., those that may discolor or degrade under high heat). For delicate products, cold seal or lower temperature options preserve quality. |
| Film material & structure | Mono‐material vs laminates; barrier layers (oxygen, moisture, UV); printable clear vs opaque; sustainable or recyclable films; films compatible with seal type. | The right film protects product, ensures shelf life, and supports branding. But film choice dictates what machine adjustments or enhancements are needed (temperature, sealing energy, film feed tension, etc.). |
| Product feeding/alignment systems | Custom conveyor / product insertion; feeders that orient or stabilize products; vision systems or sensors to detect product position. | Minimizes misfeeds, ensures that product is properly centered and aligned to the film -> better sealing, less scrap, more uniformity, higher throughput. |
| Speed/capacity & multi‐lane/multi‐head options | Machines sized to required output; possibility of using multiple lanes (“lanes” = parallel tracks) or heads to boost throughput; modular add-ons. | Helps when demand is high or when several variations must run side by side. If customizing for unique products, often output drops unless machine is designed to accommodate the product without bottlenecking feed or sealing. |
| Machine design for hygiene/sanitation | Stainless steel surfaces, washdown‐safe components, easy to clean, designs minimizing crevices; CIP (“clean in place”) where needed; minimal operator contact. | Especially important for high‐moisture or perishable foods; reduces contamination risk, supports regulatory compliance. Also reduces downtime for cleaning. |
| Changeover flexibility & control systems | Presets for film type, product size; quick‐change formers, jaws, or modules; intuitive HMI for operators; minimal toolings. | When products change (size, film, shape), changeovers are a cost center. Omori’s ability to deliver machines or retrofit kits with fast changeover processes yields savings in downtime and higher overall equipment effectiveness (OEE). |
Impact of Customization
Customizing your flow wrapper to accommodate your unique products has many positive impacts for your business:
- Reduced product damage/rejects: cutting down the scrap rate on delicate or irregular products can noticeably cut material cost and waste.
- Reduced downtime for cleaning or changeovers: faster changeovers may free up hours per week; and a better design reduces cleaning time.
- Film and material savings: Better forming, tighter fin seal, more precise film tension can reduce waste and/or trim. Even small improvements (say 2–5%) in film usage add up over high volume.
- Energy savings: lower seal temperatures, efficient motors/drives, less waste = lower overall energy cost.
- Improved throughput and consistent operation: leads to better OEE (Overall Equipment Effectiveness), plus higher output per shift and less variation in packaging quality.
- Brand value and regulatory risk: fewer consumer complaints, less spoilage, and better shelf appeal.
For many food producers, especially those making unique or non‐standard products, off-the-shelf flow wrappers may leave performance, quality, or cost on the table. With Omori North America’s thoughtful customization, we can match your product shape, film type, seal technology, and hygiene needs to the perfect flow wrapper solution. And you rest easier knowing that you have packaging that protects your product, enhances brand perception, meets regulatory demands, and contributes positively to the bottom line.
Omori is ready to guide customers through this journey, starting from product assessment, through machine specification and consumables, to installation, commissioning, and support. If you’re considering packaging options for a new food product or re-engineering the packaging of an existing one, the cost of customization is often more than offset by savings in scrap, downtime, and product damage. And you gain in quality, shelf life, and consumer satisfaction.

Most food processors and manufacturers rely on a simple manual step for padding trays before packaging meats, proteins, fruits, vegetables, etc. While this process appears straightforward, it introduces hidden costs that often go unnoticed across the packaging operation
As production demands increase and consistency becomes more critical, many processors are discovering that manual tray preparation can quietly become a bottleneck, when a more efficient pre-padded tray solution is available.
Understanding the operational impact of this step helps processors identify opportunities to improve efficiency and packaging consistency.
Labor Demands in Manual Tray Padding
Manually inserting absorbent pads into trays requires dedicated labor. Employees must handle trays, align pads correctly, and maintain pace with upstream product flow. In high volume operations this task often requires multiple employees across different shifts making sure inventory levels are maintained.
This dependency on labor, especially for a task that does not directly add value to the product, is the biggest inefficiency and contributor to unnecessary cost.
Facilities that rely on manual tray padding may frequently experience:
- increased labor costs
- difficulty maintaining staffing levels
- slower line preparation
- inconsistent workflow
When staffing levels fluctuate, tray preparation can quickly fall behind production demands. This forces downstream packaging equipment to slow down or stop while operators catch up.
Inconsistent Pad Placement
Another challenge with manual tray padding is consistency. Pads may shift, fold, or sit slightly off-center depending on how quickly trays are assembled.
Even minor inconsistencies can impact the final package quality. Improper positioning may lead to wrinkled film, poor absorption performance, or compromised product presentation during handling and transport.
Common issues include
- uneven pad alignment
- wrinkled film during wrapping
- inconsistent product presentation
- increased package rejects
Consistency is critical in food packaging. Small inconsistencies upstream can lead to quality issues further down the line.
Production Slowdowns at the Packaging Line
Efficient Packaging lines depend on smooth upstream preparation. When trays are not ready as when product arrives, the entire operation is disrupted.
These delays often occur during peak production periods. when high-speed equipment is most sensitive to interruptions.
Operations relying on manual tray padding may encounter:
- packaging line interruptions
- reduced throughput
- increased operator intervention
- higher downtime
While individual delays may last only seconds, repeated interruptions throughout a shift can significantly impact total production output.
The Efficiency of Pre-Padded Trays
Complex packaging lines often rely heavily on operator expertise to manage different product formats. When settings change between shifts or operators interpret adjustments differently, packaging performance becomes inconsistent.
Flexible tray lidding technology reduces this dependency by standardizing the sealing process.
Automated controls and repeatable machine settings allow operators to select the appropriate configuration for each SKU while maintaining consistent performance. This approach helps eliminate the trial-and-error adjustments that often accompany frequent format changes.
Building Packaging Flexibility in the Line
Modern food processing requires packaging systems that can evolve with product portfolios. Equipment that supports only a narrow range of formats quickly becomes a limitation as product offerings expand.
Flexible tray lidding machines provide processors with the ability to introduce new SKUs without redesigning the entire packaging line. By supporting multiple tray types and sealing materials, the equipment allows production teams to adapt quickly to market demands.
Omori’s Lid Sealer by Frimaq is designed with this flexibility in mind. The system supports rapid format changes while maintaining stable sealing performance and consistent packaging quality.
Packaging Technology That Keeps Pace with your Product Line
SKU complexity is unlikely to decrease. As consumer preferences continue to evolve, processors must manage more packaging formats while maintaining operational efficiency.
Tray lidding technology that supports flexibility allows manufacturers to respond to these changes without sacrificing line performance.
Omori North America provides the Lid Sealer by Frimaq, a tray lidding solution engineered to handle diverse packaging formats while maintaining seal integrity and production speed. By combining flexibility and machine design, we help processors manage growing product portfolios with confidence.
