To help businesses cut operational expenses without compromising packaging quality, our company has launched a professional VFFS vertical form fill seal packaging solution paired with customized EVA roll film. This innovative packaging method delivers a30% cost reduction compared with conventional pre-made EVA bags, bringing remarkable profit margins for bulk production enterprises. However, many clients ask a core question: Can VFFS roll film packaging fully replace all traditional EVA low melt bags?
The straightforward answer is no. VFFS roll film packaging offers outstanding cost advantages for most medium and large-capacity packaging scenarios, yet it is not a one-size-fits-all solution. The choice between roll film and pre-made EVA bags depends entirely on your specific packaging specifications and production needs.
Key Limitation of VFFS EVA Roll Film for Small-Size Packaging
The biggest difference between the two solutions lies in the material thickness adaptability for small-volume packaging (below 2kg).
For packaging weights under 2kg, traditional pre-made EVA bags work perfectly with ultra-thin material designs. Since finished bags require no secondary stretching or mechanical molding during packaging, they can adopt thinner, lighter EVA materials to save costs while meeting basic sealing and loading requirements.
In contrast, EVA roll film for VFFS machines has strict technical standards for material toughness and stretchability. The roll film must withstand continuous mechanical stretching, forming, sealing, and filling during high-speed automated operation. To avoid film breakage, leakage, or molding failure in automated production, the minimum practical thickness of VFFS EVA roll film is fixed at 80 micros. Using thinner roll film will inevitably lead to production failures and unstable packaging quality.
As a result, for small packaging sizes below 2kg, the mandatory 8μm roll film thickness makes VFFS packaging no longer cost-effective. In this scenario, traditional thin pre-made EVA bags remain the more economical and practical choice.
Optimal Application Scenarios for Two Packaging Solutions
1. Choose VFFS EVA Roll Film (30% Cost Saving)
Ideal for conventional bulk packaging specifications: 2kg, 5kg, 7.5kg and above. For these standard sizes, the automated VFFS roll film system gives full play to its advantages of low material cost, high production efficiency, and reduced labor input. It is the best choice for mass, standardized bulk feeding packaging production.
2. Choose Traditional Pre-Made EVA Bags
Perfect for small packaging sizes (below 2kg). Custom thin EVA bags can match small-volume packaging demands precisely, avoiding the cost waste caused by the fixed thickness of VFFS roll film, ensuring both cost control and packaging stability.
Final Verdict: Customize Packaging Solutions Based on Your Needs
There is no absolute “better” option between VFFS EVA roll film packaging and traditional EVA feeding bags. The best solution is always tailored to your packaging weight, production batch, and automation demands.
Our team provides one-stop customized EVA packaging services for European and American industrial clients. Whether you need cost-saving automated VFFS roll film for standard large-volume packaging or lightweight pre-made EVA bags for small-specification products, we can match the most suitable solution for your production line to maximize your cost benefits.
