Ignoring dust in the longitudinal or end seals
Packaging format
Stick-Pack Films
Stick-pack performance depends on more than barrier. Film stiffness, tracking, registration, seal response, contamination tolerance, tearing and powder behavior all influence line efficiency and consumer use.
PROJECT FOCUSA narrow lane magnifies tracking, dosing and seal contamination.
Printed film for single-serve stick packs, developed around the product, filling equipment, barrier, and seal requirements.
What the specification must resolve
What to confirm before production.
Stick-pack film has to remain stable across multiple lanes while forming around a small dose. Powder behavior, lane layout, registration, tear direction, stiffness and seal response often matter as much as headline barrier values.
Key considerations
- Machine lane count and web layout
- Powder dusting and seal contamination
- Easy-tear direction and toughness
- Moisture and aroma barrier
Common applications
- Powdered supplements
- Hydration mixes
- Sweeteners
- Instant coffee

A common question
Why can a high-barrier stick-pack film still run poorly?
Barrier does not predict tracking, stiffness, curl, friction, registration, hot tack or contamination tolerance. Those properties must fit the specific line and product.
