Abstract

The present invention provides a manufacturing method of a polyolefin resin foamed body which, when used as a packaging material, has least possibility of contaminating the surface of a contacting material, which excels in appearance and which shows antistatic characteristics uniform over the entire surface, and provides the polyolefin resin foamed body. The present invention comprises a specific mount of a polymer type antistatic agent whose apparent density may be 15 to 65 g / L, whose specific surface inherent resistance rate is 1 X 108 to 1 X 1013 (ohm), and whose average foamed body diameter meets a specific relationship.

Description

technical field

[0001] The invention relates to a polyolefin resin foam with antistatic performance and a manufacturing method thereof, in particular to a polyolefin resin foam with excellent charging performance and low apparent density and a manufacturing method thereof. Background technique

[0002] Conventional foams made of polyolefin resins are widely used as cushioning materials and packaging materials because they are rich in flexibility and cushioning properties, making it difficult to damage the packaged objects. In particular, polyethylene resin foams are widely used because they can be easily produced with high foaming and low cost. However, due to the bad properties of this foam, which is very easy to absorb dust due to static electricity, polyolefin resin foams with antistatic properties that use antistatic agents to improve conductivity are gradually being developed and applied.

[0003] As means for imparting the above-mentioned antistatic performance, surfa...
