Overview
Barrier layers and liners to improve moisture protection, cleanliness, and product integrity during storage and transit.
Protect Product Integrity
Options for moisture/grease resistance and improved cleanliness.
Reduce Risk
Choose protection levels based on storage, climate, and distribution.
Right-Sized Tradeoffs
Balance protection, cost, and line compatibility.
Common Protection Needs
Barrier selection depends on what you are protecting against and how the product will be stored and shipped.
- Moisture resistance for humidity and long transit windows
- Grease resistance for certain ingredients
- Clean handling needs (dust control and contamination reduction)
Liner Approaches
Liners can be configured to match your filling and closing workflow.
- Loose liners (depending on operations)
- Attached liners (depending on production and usage)
- Barrier layers integrated into the bag structure
How We Recommend The Build
We look at product sensitivity, storage conditions, distribution, and your line behavior to propose the best-value protection level.
FAQs
Do we always need a liner?
No. Many products perform well without liners. We recommend liners when they materially reduce moisture risk, contamination risk, or handling failures.
Coating vs liner: which should we use?
Coatings are part of the paper stack; liners are separate inner layers. The best choice depends on barrier targets, handling workflow, and whether venting/deaeration is required.
Will barrier options affect filling speed?
They can. Barrier choices can change venting and closing behavior. We recommend an option set that keeps filling stable and avoids line stoppages.
Can we keep de-aeration while improving barrier?
Sometimes. It depends on product sensitivity and the venting strategy. If barrier is critical, we may recommend liners/coatings instead of perforation-based venting.
What information helps you recommend the right protection level?
Storage time, humidity exposure, product sensitivity, any current caking/clumping issues, and your filling/closing workflow. If you have failures or returns data, that helps too.
Can you help validate performance?
Yes. We can propose prototypes and a simple validation plan: filling trial, pallet stability check, and storage exposure review.
