Here are some key points about using food grade paraffin wax on food wrapping paper: Moisture barrier: food grade Paraffin wax forms an effective moisture barrier to prevent foods from drying out or becoming soggy in contact with the paper. Grease resistance: The wax also acts as a barrier against absorption of oily/greasy foods into the paper fibers, keeping them contained. Strength: The wax adds wet strength to the paper so it doesn't disintegrate when foods release moisture over time in storage/transport. Coating thickness: A thin, uniform coating of 2-5 grams of wax per square meter is sufficient to provide barrier functions without overuse. Application method: food grade Paraffin is typically applied to paper via roller coating while the fibers are still moist from manufacturing. Safety: Food grade purity standards ensure any minor oral exposure from wax residue is safe. Recyclability: Waxed papers can be recycled if the wax coating is water-soluble to break down during pulping. Overall, food grade paraffin wax creates a cost-effective barrier layer for optimized food protection and quality in various types of wrapping papers.
