This is part 4 of our Brown Bag Blog Series dedicated to unpacking (pun intended! 😃) various bag style options for your Rovema vertical form fill seal machine. These posts, like brown bag webinars or in-person meetings, are designed to be short, sweet, and to the point. 

From our many years of experience, we know that you should take the time to carefully consider which bag style best fits your product’s needs. However, we’ve often seen throughout the industry that these VFFS bag styles are often chosen by default or given little thought.

Thinking through the strengths and considerations of different bag styles pays off greatly in the long run. 

As such, we’re releasing these posts to give you a quick overview of the various bag style options for your Rovema VFFS machine. In each, we outline the advantages and considerations of a given bag style, talk about its appearance and how it is formed, and discuss its place within current market trends.

Sachets: Great for Marketing, Great for Efficiency 

What is a Sachet Style Bag? 

Sachet Style Bags are lay flat packages with either 3 or 4 seals. These packages are economical to produce on vertical form fill and seal machines and have a high amount of print area on both the front and back panels (making them a win in most marketing teams’ books). 3 Side Seal Bag for powders and small food or pharmaceutical doses

3 side seal bags can often be produced at high production speeds, and they are especially ideal for products distributed in small quantities where accuracy is especially important. 

Though traditionally made on Horizontal Form Fill Seal baggers or multi-lane sachet machines, they are also an option for your Rovema VFFS machine. The major benefit to running sachets on VFFS vs HFFS? They have a way smaller footprint.

The Sachet Style Bag is a lay flat package with a top seal and two side seals. It also has an optional fourth seal that can be added for premium design purposes. 

Because of its design, the Sachet Style Bag is well-loved by marketing teams: it has a very high ratio of print area on both the front and back panels, unobscured by seals or seams. 

What are the advantages of a Sachet Style Bag? 

As mentioned above, the Sachet Style Bag is dreamy for marketing teams because of the large panels on which they can print graphics, copy, and other required information. Sachet Style Bags are also simple and economical to make, and it is easy to achieve high production speeds with them on your Rovema VFFS machine. 3 Side Seal Bag for powders and small food or pharmaceutical doses

This bag style is great for smaller product amounts where accuracy is important, and they can easily be customized to include hole punches and easy open and reclosable features. 

What are considerations for Sachet Packaging? 

When choosing which bag style to use for your Rovema VFFS bagger, it is important to think through both the strengths and considerations of a given bag style. A few questions you might want to ask yourself if you are considering a Sachet Style Bag are: 

  1. Do I need a pouch that has stand up ability? Since the Sachet Style Bag is not a stand up pouch, you might want to consider Block Bottom Bags, Flex Can Packages, or another style of stand up package. 
  2. Am I comfortable with a high packaging material to product ratio? To achieve the full front and back panel design, the Sachet Style Bag does have a higher packaging material to product ratio than other VFFS bag styles. 
  3. Do I need to package large quantities of my product? The Sachet Style Bag is usually more well-suited for smaller amounts of product.
