て広く利用されている。 Ultra-high molecular weight polyethylene has a molecular weight of approximately 100,000 to 50
It is a high-density polyethylene of 10,000 yen and is used as an ultra-thin reinforcing material, and is processed into an ultra-thin film with a thickness of 10 to 15 μm, for example, by inflation molding, and is widely used as food packaging film, agricultural mulch film, etc. ing.

スの高い）樹脂を選択するのが一般的である。 Such ultra-high molecular weight polyethylene is colored using a so-called colored masterbatch in which pigments are dispersed at high concentrations at various base times. In this case, the pigment needs to be well dispersed in the ultra-high molecular weight polyethylene (diluent resin) to be colored, and for this purpose the base resin used must contain a substance that is sufficiently compatible with the diluent resin. For this reason, the same resin as the diluted resin is generally selected as the base resin, or a resin that exhibits the same physical properties (melt index, density, etc.) as the diluted resin, or a resin that is more fluid than the diluted resin. It is common to select a resin with a good melt index (high melt index).

ではない。 However, even when the above-mentioned high-density colored masterbatch is used, when a colored ultra-thin film is processed by inflation molding, coarse pigment particles are generated in the film. This is because even if the pigment is finely dispersed in the colored masterbatch, the colored masterbatch is not sufficiently diffused into the diluted resin during inflation molding, causing a phenomenon similar to poor pigment dispersion. be. For this reason, attempts have been made to further improve the fluidity of the colored masterbatch to prevent the above-mentioned phenomenon, but with this method, even if the apparent dispersibility can be improved, MD (vertical direction)
This is not preferable because it causes a decrease in physical properties such as tear strength.

After blending 78 parts and 922 parts of diluted resin Idemitsu 640uF in a tumbler, this blend was heated to 65m/mφ.
A colored inflation film with a thickness of 15 μm was produced using an inflation device (manufactured by Plako Co., Ltd.) at a set temperature of 180 to 210°C. The finished film was smooth, with almost no coarse particles (60 μm or more) observed, and no decrease in tear strength in the MD (vertical direction) was observed, indicating a good balance of strength in the longitudinal and lateral directions.
