Introduction The objective of package printing and decorating is to create a visibly identifiable image, consistently, for a large number of impressions. these have been divided into two groups: .\Printing\ in the context of this discussion refers to flexography, lithography and gravure--the methods that

Throughout the distribution system, packages are manhandled and mishandled in various ways: dropped, thrown, kicked and otherwise roughly abused; fall from conveyors or forklifts and crash to the floor;

Introduction Packaging can be unnecessarily expensive in a couple of ways: 1. Inadequate design results in shipment damage 2. Over-design or poor design (more protection than is required or materials being incorrectlyused) results in excessive material cost. The procedure can be broken down into seven basic steps

在人类即将跨入21世纪的时候,如果我们回顾一下自身的发 展历史,就会发现,近百年来人类所创造的劳动业绩,大大超过 了在此之前所积累的总和。17世纪以前,人均能源消耗与史前期 相差不大,从17世纪中叶起,人口开始以指数规律增长。18世纪 蒸汽机的发明,引起了产业革命,从此,在人类的经济活动中出 现了一个新的生产领域:使用机器的工业生产。19世纪发现了电 磁现象,奠定了现代技术的基础,机器生产从蒸汽机供应能量转 向了新的能源形式一电力
