Why a Glassine Lining Blocks Grease
Glassine is a smooth, dense, grease-resistant paper bonded inside the bag. It blocks the butter and oil that soak through a single layer of kraft, so the bag stays clean and the pastry stays presentable. The lining also holds in a little moisture, which suits softer, richer items. The outer kraft or white surface still takes your full print, so the barrier is invisible from the outside.
When to Choose Glassine-Lined Over Plain
Choose glassine-lined for croissants, butter cookies, donuts, and fried pastries where grease is heavy. Choose plain kraft bakery bags for drier items like bread and plain cookies, where breathability matters more than a moisture barrier. Match the bag to how greasy the item is.

Frequently Asked Questions
What are glassine-lined bakery bags for?
For buttery and fried items like croissants, donuts, and butter cookies. The glassine lining blocks the grease that soaks through a plain paper bag.
How is a glassine lining different from plain kraft?
Plain kraft resists grease but breathes. A glassine lining adds a stronger grease and moisture barrier for richer, oilier items.
Can glassine-lined bags still be printed?
Yes. The outer kraft or white surface takes your full print, so the barrier is invisible from outside.
Are glassine-lined bakery bags recyclable?
The added lining reduces recyclability compared with plain kraft. Choose plain kraft or white when recyclability is the priority.
