With the variety of snacks available on every aisle to shop, it’s crucial that your product stands out. 

Generic packing covers or basic bags may protect your product but they could easily blend in. Not to mention the higher unit cost and potentially slow manual filling processes.

That’s exactly why using roll film, whether for your loose or delicate snacks, is a practical choice. This material is becoming an industry standard and this article will show you how to make the most of it.

What Is The Best Material for Snack Packaging?

Packing covers are flexible materials that shield food from foreign elements like moisture and oxygen. For snacks, roll film takes that protection up a notch. It is a continuous sheet of packaging material wound onto a central core that makes efficient packaging.

Why use roll film instead of pre-made bags for snacks?

As earlier mentioned, pre-made snack packaging bags work. But as your production volume grows, roll film becomes the clear winner for several reasons:

• Lower Cost per Unit: Roll films are supplied in bulk rolls. So the large purchases save you significant costs compared to buying individual pre-shaped bags.

• Versatility: Imagine a single roll of film that can be adjusted on your machinery to create different bag lengths. That’s the flexibility roll film gives your snack packaging. 

• Reduced Storage: Rolls of film take up much less of your warehouse space than boxes of pre-made bags.

Which Type of Packaging Film Keeps Snacks Fresh?

Your product determines the best film for your business and its customers. Since snacks are sensitive to oxygen and moisture, the material you choose must act as a high performance barrier.

Common Materials Used in Snack Bags:

• Polyethylene (PE) and Polypropylene (PP): These plastic materials are efficient and widely used in the snack packing industry. They may be a fit for your product if you prioritise flexibility and moisture resistance. 

• PET (Polyester): This packaging material is often used as an outer layer. It provides a high-gloss finish and handles heat well during the sealing process.

• Specialized Barrier Films: As the name implies, these films are often laminated layers. They may include foil or metallized coatings to keep oxygen out and ensure your snacks don’t go stale.

• Eco-Friendly Options: Many snacks consumers are increasingly prioritising sustainability. So, compostable or recyclable films appeal to this growing market and reduce your environmental footprint.

How Do Machines Turn Roll Film into Snack Bags?

The right machine for your snack packaging depends entirely on the physical characteristics of your product and production volume.

Snack packaging machines convert your roll film into a finished, shelf-ready product.

Choosing the Right Equipment

You generally have two primary paths based on how your snack needs to be handled:

Vertical Form Fill Seal (VFFS)

If you are bagging loose, flowable items like chips, popcorn, pretzels, or nuts, you need a VFFS machine.

How it works: The VFFS machine pulls the roll film over a forming tube, seals the vertical seam and the bottom (creating a bag), and then allows gravity to drop your product directly into the bag.

Why use it: It is an efficient way to package high-volume snacks and has a smaller footprint in your facility.

Bag style: The machine creates pillow bags or gusseted bags which you can commonly find in the snack aisle.

Horizontal Form Fill Seal (HFFS)

For snacks that are delicate, rigid, or need to be laid flat, like protein bars, cookies, or chocolate-covered biscuits, the HFFS machine is your best option.

How it works: As the name implies, your product moves horizontally along a conveyor belt. The roll film is wrapped around it and sealed at both ends.

Why use it: The HFFS prevents the breakage that occurs with gravity-fed systems and ensures your snack is positioned perfectly within the packaging.

Bag style: This snack packing machine forms flow wraps or single-serve pouches that need to maintain a specific shape for better shelf presence.

How Can I Reduce My Snack Packaging Costs?

One of the fastest ways to improve your bottom line is switching to an automated system using roll film. You’d get:

• Faster Production: A snack packing machine allows you to package hundreds of units per minute, far outpacing manual labor.

• Less Waste: Modern machines are much more precise. This ensures you produce fewer rejected bags and less wasted film.

• Custom Branding: Roll film can be custom-printed with your logo and nutritional info, eliminating the need for expensive secondary labels.

How Do I Choose a Snack Packaging Supplier?

It’s one thing to select the right material and machine for your snack packaging but choosing a partner is just as important. When looking for a credible manufacturer, consider these three factors:

• Material Compatibility: Is their film compatible with your specific packaging machinery? This is the first major concern when choosing a roll film supplier.

• Lead Times: A delay in film delivery means a delay in getting your product to shelves. The goal is to speed up efficient production, not slow it down.

• Technical Support: Look for a partner who can help you troubleshoot issues on the production line, not just someone who sells you a roll of plastic.

Conclusion

Finding the right way to package your snacks shouldn’t be a headache. While simple packing bags might get you off the ground, they eventually lead to higher costs and slower production that can hold your business back.

Moving to roll film is a practical step you can take to lower your unit costs, speed up your output, and make sure your snacks stay as fresh as the day they were made.
