Background
The laminated paper is a composite paper formed by attaching PE (polyethylene) and PP (polypropylene) plastics on a paper substrate by adopting a special process. Generally used for waterproof and leakproof food containers, wrapping paper and various moisture-proof papers. Polyolefin (including PE and PP) laminated paper in the laminated paper has better anti-sticking property and moisture resistance, so the application is wider. The coated paper has the advantages of moisture resistance, oil resistance, good isolation effect and the like, and is widely applied to the industries of advertisement, printing, packaging, electronics and the like. The laminated paper is a composite material with plastic particles coated on the surface of paper by a casting machine, and is mainly characterized in that the composite material can resist oil and water (relatively) and can be thermally sealed. Different purposes adopt different characteristics: when used for packing hamburgers, it is oil resistant. The Madanuo is edible vegetable oil with the temperature of 80 ℃ and does not leak oil for 10 minutes. When the coating is used for coated paper ream packaging, the coating has waterproof property. When used for packaging by an automatic packaging machine, the heat-sealable characteristic is taken.
