Description

Technical Field

[0001] The utility model relates to a pressure-resistant glassine paper. Background Art

[0002] Glassine paper is a kind of industrial paper. Glassine base paper is made into glassine paper after coating. Glassine paper has a dense and uniform texture, good internal strength and light transmittance, and is a common material for making barcode labels, stickers, tapes or sticky industrial products. It is particularly suitable for rotary and flat die-cutting. In addition, glassine paper has the functions of high temperature resistance, moisture resistance, and oil resistance. It is generally used for packaging in food, medicine and other industries. At present, the glassine paper applicable in China is divided into coated and uncoated types according to the production process. The existing glassine paper is a single-layer structure.
