Choosing the Right Packaging Film: PE vs. PVC for Tray Overwrappers

April 2025

When it comes to tray overwrapping, the type of film you choose can make or break your packaging process — affecting sustainability, performance, and product appeal. Polyethylene (PE) and polyvinyl chloride (PVC) are two of the most common films used in food packaging, but they’re far from interchangeable. At Omori, we’ve engineered our systems to adapt to both — with innovations that make PE film a stronger contender than ever before.

The Case for PVC: The Classic Performer

PVC film has long been favored, and it still is, for good reason. But it’s not without its drawbacks.

Advantages of PVC Film:

• High Clarity & Shelf Appeal: PVC delivers a glossy, transparent finish that makes food products stand out on the shelf.
• Memory & Shrinkability: It forms tightly around trays and maintains its shape, which helps preserve product integrity and presentation.
• Strong Cling & Seal: Its ability to stretch and grip the tray provides excellent wrapping consistency, especially at high speeds.

Drawbacks of PVC Film:

• Environmental Concerns: PVC is less environmentally friendly — it’s difficult to recycle and releases harmful byproducts during production and disposal.
• Regulatory Scrutiny: Increased regulations around chlorine-based plastics are pressuring manufacturers to look for alternatives.
• Limited Consumer Favorability: As consumer demand for eco-friendly packaging grows, PVC is becoming a less marketable option for many brands.

PE Film: The Recyclable Contender

PE film is rapidly becoming the film of choice for brands looking to reduce their environmental impact. Historically, though, PE film has had issues.

Advantages of PE Film:

• Recyclable & Safer: PE film is widely recyclable and doesn’t release the harmful compounds associated with PVC, making it a more environmentally responsible choice.
• Regulatory Friendly: PE meets growing global packaging regulations focused on recyclability and chemical safety.
• Lower Carbon Footprint: Its production and disposal processes are cleaner and less toxic.

Drawbacks of PE Film:

• Performance Challenges: PE doesn’t naturally cling, stretch, or conform as well as PVC, which can lead to looser wraps or compromised presentation if not paired with the right equipment.
• Film Memory: PE lacks the “snap-back” of PVC, so achieving a tight, shelf-ready finish requires specialized heat and pressure.

Omori’s Heat Tunnel Machine: Bridging the Performance Gaps

Here’s where Omori makes the difference. Our heat tunnel innovation transforms how PE film performs — enhancing its ability to stretch, conform, and seal with precision. The result? A PE-wrapped tray that rivals the look and feel of traditional PVC packaging, without the environmental trade-offs.

Our heat tunnel machine allows food manufacturers to make the switch to PE without sacrificing efficiency or shelf appeal. You get the performance you need — and the recyclability to meet today’s market demands.

Future-Proof Your Packaging

Consumer preferences and regulations are evolving. Omori’s commitment to film flexibility ensures your operation stays ready — whether you’re sticking with PVC for now or making a strategic move toward PE.

Thinking about switching to PE? Let’s talk. Omori has the technology to make it work — without compromise.
