Title
(EN) Decorative multilayered extrusion blowing bottle
(ZH) 装饰多层挤出吹塑成形瓶
Abstract
(EN) A decorative multilayered extrusion blowing bottle provided with an inner layer that is formed from a polyethylene (A) and a metallic layer that is arranged outside the inner layer, has an average thickness of 600 nm or less and comprises a polyethylene (B) and a metal pigment dispersed in the polyethylene (B). The decorative multilayered extrusion blowing bottle is characterized in that, when theshear viscosities (Pa*s) of a resin forming an inner adjacent layer to the metallic layer as measured at shear rates of 6 s<-1> and 30 s<-1> at a temperature of 210 DEG C are respectively representedby V6 and V30, the shear viscosities [eta]6 and [eta]30 (Pa*s) of the polyethylene (B) as measured at shear rates of 6 s<-1> and 30 s<-1> at a temperature of 210 DEG C meet the following viscosity requirement formulae (1) and (2): (1) [eta]6 >= V<6> - 2000; and (2) [eta]30 >= V<30> - 2000.
(ZH) 一种装饰多层挤出吹塑成形瓶,其设置有由聚乙烯(A)形成的内层和设置在内层的外侧的分散有平均厚度为600nm以下的金属颜料的聚乙烯(B)的金属色层。该装饰多层挤出吹塑成形瓶的特征在于,当形成金属色层的内侧相邻层的树脂的在210℃的温度下测量的在6s‑1和30s‑1的剪切速度下的剪切粘度(Pa·s)分别由V6和V30表示时,聚乙烯(B)的在210℃的温度下测量的在6s‑1和30s‑1的剪切速度下的剪切粘度η6和η30(Pa·s)满足以下粘度条件式(1)和(2):(1)η6≧V6–2000;和(2)η30≧V30–2000。
