Pre-opened bags on a roll
Pre-opened bags on a roll are made for automatic packaging. If you pack by hand today, they help you move to a fast, continuous line with fewer stops and lower cost.
Advantages of pre-opened bags on a roll
Faster line
You pack more in less time with fewer stops.
Less labor
You leave manual packing behind and lower your staffing costs.
Made to fit
Width and length based on your product.
With your brand
Printed with your logo or with the information your product needs.
Fast roll changeover
With the roll's cardboard ears, you take down the finished roll, load the new one and your line keeps going.
Designed for high-speed packaging
Each bag arrives open and in sequence on the roll, so your team loads, seals and keeps going without stopping to arrange bags. We make them based on your product, your volume and your bagger.
How they work in the bagger
Bags on a roll are made from tubular film sealed across the width and perforated between one bag and the next. That way they arrive joined, in sequence and ready for your line.
Load the roll
The roll goes on the bagger and the bags advance in sequence, joined by the perforated line.
The bag arrives open
Each bag arrives open at the loading zone. Nobody has to find the opening or separate the sides.
Load the product
Your team or your line places the product inside the bag.
It is sealed and separated
The bag is sealed and torn off the roll at the perforation. The next one is already in place.
