Description

Heat-resistant release paper Technical Field The utility model relates to the technical field of release paper, in particular to heat-resistant release paper. Background The release paper tape is provided with a silicon oil layer and has certain heat resistance, so that the release paper tape is used for containing food materials in microwave heating. The existing release paper cannot be combined with the tinfoil to form a more heat-resistant composite release paper structure, so that two heat-resistant materials cannot be used simultaneously. A great deal of research is being conducted on the technology to solve the technical problem of improving the heat resistance of release paper by using tinfoil. Disclosure of utility model The utility model aims to provide a heat-resistant release paper which can solve the problems in the prior art. The heat-resistant release paper is realized by the following technical scheme that the heat-resistant release paper comprises a raw paper layer and is characterized in that a first tin paper layer is arranged on the lower side of the raw paper layer, tin paper flanging is arranged on two sides of the first tin paper layer, a second tin paper layer is arranged on one side of the tin paper flanging, a paper layer positioned in the middle is arranged on the upper side of the raw paper layer, the paper layer positioned in the middle, the second tin paper layer, the first tin paper layer and the first tin paper layer are fixedly matched and connected with the raw paper layer, and a silicon oil layer is arranged on the tops of the second tin paper layer and the paper layer positioned in the middle. According to a further technical scheme, the second tin paper layer is propped against the top surface of the raw paper layer. According to a further technical scheme, the tinfoil flanging is abutted against the side edge of the raw paper layer. According to a further technical scheme, a plurality of inner holes are formed in the raw paper layer, and the diameters of the inner holes distributed from the center to two sides are sequentially increased. According to a further technical scheme, glue layers are arranged on the left side, the right side and the lower end face of the upper end of the raw paper layer, the glue layers are adhered and fixed with the middle paper layer after overflowing from the inner hole, and the glue layers are adhered and fixed with the first tin paper layer, the tin paper flanging and the second tin paper layer.
