MG/MF Kraft Paper refers to machine glazed (MG) or machine finished (MF) kraft paper, which is a type of paper produced with specific surface finishes and properties. There are white (bleached) and brown (unbleached) kraft paper.  Here’s a breakdown of its characteristics and uses:

1. Machine Glazed (MG) Kraft Paper

Production Process: Made on a Yankee dryer, where one side is pressed against a highly polished, heated cylinder, giving it a glossy, smooth finish on one side while the other remains rough.

Features:

High gloss on one side, matte on the other.

Good strength and moisture resistance.

Flexible yet durable.

Common Uses:

Packaging for food (e.g., butter, cheese wraps).

Labels, envelopes, and laminates.

Industrial applications like cement bag liners.

 

2. Machine Finished (MF) Kraft Paper

Production Process: Smoothed by calender rolls (not as glossy as MG), resulting in a more uniform but less shiny surface compared to MG.

Features:

Moderate smoothness on both sides.

Good printability and strength.

Often bleached or unbleached.

Common Uses:

Multi-wall sacks (e.g., for flour, animal feed).

Grocery bags, wrapping paper.

Industrial padding and interleaving.
