Abstract
본 발명은 폴리올레핀계 수지, 무기 또는 유기 충전제 및 생분해성 및/또는 광분해성 제3성분을 함유하는 조성물을 연신가공하여 얻어지는 분해성을 가진 통기성 필름 및 그 제조방법을 제공하는 것을 특징으로 한다. 보다 구체적으로 폴리올레핀계 수지 100중량부에 대하여 무기 또는 유기 충전제가 50-500중량부로 첨가되고, 생분해성 제3성분으로 미립상 전분 또는 그 유도체를 폴리올레핀계 수지 100중량부에 대해 2-50중량부로 첨가되는 조성물을 연신가공하여 얻어지는 것을 특징으로 한다.The present invention is characterized by providing a decomposable breathable film obtained by stretching a composition containing a polyolefin resin, an inorganic or organic filler and a biodegradable and / or photodegradable third component, and a method for producing the same. More specifically, 50 to 500 parts by weight of an inorganic or organic filler is added to 100 parts by weight of polyolefin resin, and 2-50 parts by weight of particulate starch or a derivative thereof to 100 parts by weight of polyolefin resin as a third biodegradable component. It is obtained by extending | stretching the composition to add.
본 발명은 또한 광분해성 제 3 성분을 공지의 광분해 촉진제를 폴리올레핀계 수지 100중량부에 대해 0.005-5중량부로 단독 또는 2종 이상 혼합물로 첨가되는 조성물을 연신가공하여 얻어지는 것도 포함된다.This invention also includes the thing obtained by extending | stretching the composition which adds a photodegradable 3rd component to a 0.005-5 weight part of well-known photolysis promoter with respect to 100 weight part of polyolefin resin, individually or in mixture of 2 or more types.
본 발명은 또한 분해성 제 3 성분으로 미립상 전분 또는 그 유도체 및 광분해 촉진제가 동시에 첨가되는 조성물을 연신가공하여 얻어지는 것도 포함된다.This invention also includes the thing obtained by extending | stretching the composition to which particulate starch or its derivative (s) and a photolysis promoter are added simultaneously as a degradable 3rd component.
본 발명에 의하면 양호한 외감과 촉감, 우수한 강도 및 적정투습성을 가질 뿐만 아니라 빛이나 미생물에 의해 분해되는 특성을 갖는 폴리올레핀계 통기성 필름을 얻게 된다.According to the present invention, a polyolefin breathable film having not only good outer appearance and feel, excellent strength and adequate moisture permeability but also decomposed by light or microorganisms is obtained.
