Does kraft paper provide the main food barrier?
Usually no. Moisture, oxygen, aroma and sealing performance normally come from the complete inner laminate.
Is every kraft paper pouch recyclable?
No. Classification depends on all films, coatings, adhesives, barriers and local collection systems.
Can a kraft pouch have a transparent window?
Potentially. Final clarity depends on the window film, ink and white-ink knockout, adhesive, varnish and production sample.
What is the difference between VMPET and aluminum foil inside kraft bags?
VMPET is metallized PET; aluminum foil is a separate foil layer. They differ in barrier, flexing, cost and converting behavior.
Why can kraft pouch color vary?
Paper shade, fibre texture, print coverage, lamination and folds can affect appearance. Approve a representative physical sample.
