The present invention relates to a method for manufacturing a protection film (340, 440) obtained by laminating an adhesive layer (341, 441) and a non-adhesive layer (345, 445). The non-adhesive layer is obtained by the steps of: a) producing fine particles (345b, 445b) through a polymerization process; b) mixing the fine particles with a synthetic resin (345a, 445a); and c) forming a mixture of the fine particles and the synthetic resin into a layered shape. In addition, the present invention provides the protection film formed by laminating: the non-adhesive layer including a first synthetic resin and the fine particles, which are dispersed in the first synthetic resin and are polymers; and the adhesive layer including a second synthetic resin. 본 발명은, 점착층(341, 441)과 비점착층(345, 445)이 적층된 보호필름(340, 440)을 제조하기 위한 방법으로서, 상기 비점착층은, a) 중합공정을 통하여 미세입자(345b, 445b)를 제조하는 단계와; b) 상기 미세입자를 합성수지(345a, 445a)와 혼합하는 단계와; c) 상기 미세입자와 상기 합성수지의 혼합물을 층상으로 성형하는 단계를 통하여 얻어지는 것을 특징으로 하는 보호필름 제조방법을 제공한다. 또한, 본 발명은, 제1합성수지와 상기 제1합성수지 내에 분산되고 중합체인 미세입자를 포함하는 비점착층과; 제2합성수지를 포함하는 점착층;이 적층되어 이루어지는 보호필름을 제공한다.
