What are the advantages of laminated paper?

Laminated paper is a composite material formed by coating plastic particles on the surface of paper through a casting machine. It can resist oil, water, and is heat - sealable. Different uses take advantage of its different characteristics: when used to package hamburgers, its oil - resistant property is utilized. Technology and Advantages of Laminated Paper The technical indicators of laminated paper include the following: dry silicone coating amount, normal - temperature peeling force, aging peeling force, and residual adhesion rate. The dry silicone coating amount refers to the amount of release agent coated on the material, with the unit being grams per square meter. Professional testing equipment is required to measure the coating amount. The amount of silicone oil coating directly affects the peeling performance. Reliable manufacturers adjust the peeling force by modifying the chemical formula without reducing the amount of silicone oil coating. This requires a long - term accumulation of technology. The normal - temperature peeling force is the peeling force data obtained through a standard test method at normal temperature, with the unit being N/25mm, which can be converted into grams. The aging peeling force is the peeling force data measured after aging, generally slightly larger than the normal - temperature peeling force. Ordinary paper is composed of wood fibers and has strong water absorption. As we all know, paper absorbs moisture and is afraid of moisture. By using a laminating machine, PE plastic is melted and evenly coated on the surface of the paper to form a very thin film. Since it is melted onto the paper surface, the paper and the PE film can be firmly combined and are not easy to separate. Moreover, the entire process does not use heat - sealing chemical solvents, which is very environmentally friendly. In the later secondary processing and packaging, no adhesive is needed. Sealing can be directly achieved by relying on this layer of PE film under heat - melting. Laminated paper is a composite material formed by coating plastic particles on the surface of paper through a casting machine. The main features of laminated paper are that this composite material can resist oil, water (relatively), and is heat - sealable.
