Embodiment 1
[0055] As shown in Table 1, based on the total wt% of the masterbatch, 1 wt% of spherical alumina (aspect ratio: 1.02) as the component of the inorganic particles (A), 5 wt% of PMMA as the component of the organic particles (B) Beads (KOLONDiasphere) and 2% by weight of kaolin having irregular lumps as the component of the inorganic particles (C) were mixed into nylon 6 having a relative viscosity of 3.3, and the resultant was used at 245° C. by using a twin-screw type extruder. The mixture prepares a mixed masterbatch.
[0056] Then, according to the contents shown in Table 3, the above mixed masterbatch was mixed into nylon 6 having a relative viscosity of 3.3. A nylon film was produced by extruding the resulting mixture at 265° C. using a circular die, biaxially stretching three times at a draw ratio of 3 in a tubular manner, followed by thermal curing. In addition, aluminum foil was adhered to the manufactured film to produce a pouch, and then the depth of the pouch was m...
Embodiment 2 to 6
[0059] In addition to controlling the particle size and content of inorganic particles (A), organic particles (B) and inorganic particles (C) as shown in Table 1, and controlling the relative viscosity of nylon 6, each mixed master was prepared in the same way as in Example 1. material.
[0060] Then, at the content shown in Table 3, the mixed masterbatch was mixed into nylon 6 having a relative viscosity of 3.3. A nylon film was produced by extruding the resulting mixture at 265° C. using a circular die while simultaneously biaxially stretching three times in a tubular manner at a draw ratio of 3, followed by thermal curing. In addition, aluminum foil was adhered to the fabricated film to produce pouches, and the depths of the pouches were measured and recorded in Table 3.
[0061] The results are reported in Table 3.
Embodiment 7
[0063] Spherical synthetic zeolite as a component of the inorganic particles (A) was mixed into nylon 6 having a relative viscosity as shown in Table 1 so that the content of spherical synthetic zeolite was as shown in Table 1 based on the total wt% of the masterbatch, and Masterbatch A was prepared in a similar manner to Example 1 using the resulting mixture by using a twin-screw type extruder at 245°C.
[0064] PMMA beads (KOLONDiasphere) as an organic particle (B) component were also mixed into nylon 6 having a relative viscosity as shown in Table 1, so that the content of PMMA beads was as shown in Table 1 based on the total wt% of the masterbatch , and using the resulting mixture to prepare masterbatch B in a manner similar to Example 1.
[0065] Block kaolin as a component of the inorganic particles (C) was mixed into nylon 6 having a relative viscosity as shown in Table 1 so that the content of block kaolin was as shown in Table 1 based on the total wt% of the masterbat...
