Title:
二軸延伸エチレン重合体フィルムおよび包装体
Document Type and Number:
Japanese Patent JP6470296
Kind Code:
B2
Abstract:
The invention relates to a biaxially oriented ethylene polymer film obtained from an ethylenic polymer composition (A) having a density, heat of fusion (ΔHT) obtained by differential scanning calorimeter (DSC), heat of fusion (ΔHL) in the range from the fusion start temperature to 110°C, heat of fusion (ΔHH) in the range from 110°C to the fusion end temperature, and (ΔHH)/(ΔHL) each within certain ranges, wherein the biaxially oriented ethylene polymer film is characterized in that the thermal shrinkage characteristic (thermal shrinkage rate) of the biaxially oriented ethylene polymer film has a sum [MD + TD] of the thermal shrinkage rate (%) in the machine direction (MD direction) and the thermal shrinkage rate (%) in the transverse direction (TD direction) of 15% < [MD + TD] < 85% by heat shrinkage rate at 120°C.
