What is rollstock?
Rollstock is film that has been rolled up to be used in packaging equipment that will shape and form the bag. Layfield can fully customize any rollstock as we develop, extrude, laminate, slit, coat and print the film in house. This allows us to control and maintain the highest quality standards throughout the production process. Because Layfield’s medical films are manufactured under the same facility, all other markets especially food products can benefit from the same safety and quality control standard certified by ISO 9001 and HACCP PACsecure.
Rollstock films are available are available up to 51” or 1.3 metres wide on either 3” or 6” cores. You can print up to 12 colors on Rotogravure or Flexographic. Layfield offers many different structures and materials but the most popular categories are:
- Degradable Films
- High Barrier Films
- Functional Films
- Economic Films
Vertical Form Fill Seal VFFS Rollstock
The Vertical Form Fill and Seal (VFFS) machine application forms the film into the shape of a tube (pouch), fills the pouch vertically with product, and then seals the pouch. This is different from filling a finished bag because the bag is made along with the filling process. Rollstock used in Vertical Form, Fill, and Seal (VFFS) machines can package a variety of consumer products, mostly in loose form, such as: cereal, chips, nuts, coffee, pet food, detergent, and candies. These items are dispensed and dropped in a vertical matter into formed pouches and then sealed.
Horizontal Form Fill Seal HFFS Rollstock
Horizontal Form Fill and Seal (HFFS) machines application forms the film into the shape of a horizontal tube, fills the pouch horizontally with product, and then seals the pouch. Horizontal machines are mainly used for solid products such as candy bars, granola bars, and trays of cookies. Instead of having the product dropped vertically, it is rather slid horizontally inside the package.
Other rollstock applications:
- Cold seal
- Forming and thermo forming films
