包装体及保存方法;PACKAGE AND PRESERVATION METHOD

摘要

[1] 一种包装体，系由含有聚酯树脂(A)、聚醯胺树脂(B)、及氧化反应促进剂(C)之树脂组成物构成； 令包装体之包装体厚度为d(μm)、包装体中之聚醯胺树脂(B)之分散粒子之长径平均值为L(μm)、短径平均值为W(μm)、体积分率为Vf时，满足下式(1A)， 包装体制作后经过100小时后之透氧率为0.01[cc/(packageday0.21atm)]以下且雾度值为8%以下； 10＜d×L×Vf/2W＜120　　(1A)； 及[2] 一种物品之保存方法，系于含有聚酯树脂(A)、聚醯胺树脂(B)、及氧化反应促进剂(C)之包装体中填充物品并保存之方法； 该包装体中之聚醯胺树脂(B)之含量为2.0~3.5质量%，令该包装体制作后经过100小时后之包装体之透氧率为X[cc/(packageday0.21atm)]、包装体容量为V[L]、包装体质量为M[g]时，满足下式(1B) X/｛2.5×V2/(M-8)｝＜0.3　　(1B)。; and also provides [2] a method of preserving goods in a package containing a polyester resin (A), a polyamide resin (B), and an oxidation reaction promoter (C), wherein the polyamide resin (B) content of the package is from 2.0 to 3.5% by mass, and the preservation method satisfies formula (1B) shown below, in which the oxygen transmission rate after 100 hours have elapsed since manufacture is represented by X [cc/(package·day·0.21 atm)], the volume of the package is represented by V (L), and the mass of the package is represented by M (g). 10 ＜ d×L×Vf/2W ＜ 120　　 (1A) X/{2.5×V2/(M-8)} ＜
