Glassine (Glazed Transparent Paper)
From Cargo Handbook - the world's largest cargo transport guidelines website
The majority of Glassine is exported in reels, but when sold in sheeted form is packed in individually wrapped reams with wooden cases or bales or on wrapped pallets. Moisture damage causes surface disfiguration, dicoloration and wrinkling. A common cause of damage, apart from moisture, is physical impact causing damage to the edge of the reel or collapse of the core. Heat causes Glassine to go brittle, blister or char, but not to stick together.
