Packaging Container Structure Design and Manufacturing - Basics (4)

Section 7 Packaging Container Standards and Standardization

First, the importance of packaging standardization

a Conducive to improve packaging production efficiency
b Easy to identify, measure and use
c Helps save material and reduce costs
d Helps ensure packaging quality and reliability
e is conducive to the recycling and use of packaging containers

Second, the main content of the standardization of packaging

The standardization of packaging mainly proceeds from the following aspects:

Packaging materials, structural modeling, size, packaging capacity, packaging markings, sealing methods, tying methods, etc.

When we design the packaging structure, we must strictly follow the national standards. If it is the packaging abroad, it should be carried out according to the international packaging standards or the standards of the exporting country. National packaging standards can refer to "China Packaging National Standards Collection" or find it online.

Section VIII Packaging Container Structure Design and CAD Software

With the improvement of the production level and the development of foreign trade, people have also put forward higher requirements for the quality of packaging containers.

However, some domestic packaging companies still use traditional manual design and processing techniques and it is difficult to meet the requirements of modern industry for packaging.

Therefore, CAD/CAM technology was introduced to realize the modernization of packaging design and manufacturing.
Currently used CAD software includes AutoCAD software, carton CAD system software and so on.

I. Introduction to AutoCAD Software

AutoCAD is a general-purpose microcomputer-aided drawing and design software package launched by AutoCAD Corporation in the United States in December 1982.

The main features are as follows:

a adopts an advanced user interface
b Provides a rich set of open interactive drawing and editing command sets
c System library data and file user batch
d provides multiple uses of the interface technology
e Use of the AutoLISP language and C language

二.Carton CAD System Software Introduction

In recent years, some universities and research institutes in China have also developed carton CAD software, such as the “FounderPack” packaging design system developed by Peking University Foundry, which enables the carton structure design, decoration design, and full-page imposition output to be integrated into a common box. The library design box structure, and with the relevant software to complete the text box, graphic design, and can output the relevant die-cutting data.

The CAD system has the following basic functions:
a quick calculation, generate graphics
b Store a large amount of program and data information and achieve fast retrieval
c Man-machine interaction communication operation function
d has the shape of the input graphic, the means of design parameters

e Output data information and graphics solve problems.

Section 9 Structural Design and Ergonomics of Packaging Containers

There are four types of hand-to-container actions:
Grasp the action ----- open the mobile shaking support action ----- support the touch action ----- exploration generally speaking, the diameter of the container should not be less than 2.5 centimeters, the container with a large grip should be used. The length will be longer than the width of the hand.


Section 10 Evaluation of Packaging Container Structure Design

The design evaluation is to evaluate the structural design proposal put forward in the design process, determine the pros and cons of the actual structural design plan, and determine the advanced design and economic level of the plan. The specific design evaluation content includes the following aspects:

(I) Technical evaluation

That is, to ensure the achievement of functional goals in terms of technological advances and the extent to which the functions are implemented. The technical evaluation verification method is as follows:

a. Sample verification Prototype sample, and the sample through the actual use of the test, to obtain the necessary technical evaluation data.
b. Model Verification The design parameters in the design plan are modeled and the necessary preliminary evaluation data are obtained under the simulation conditions.
c. Theoretical verification Theoretical calculations are performed on the technical parameters in the design plan to obtain technical evaluation data for comparison.

(II) Economic evaluation

That is, the comparison between the implementation cost of the structural design scheme and the possible economic benefits, that is, the comparison of cost and benefit

(III) Social Evaluation

That is, the social benefits of structural design programs, which include improving social productivity, promoting technological advancement, environmental protection, and effective use of resources, etc. Evaluation of design plans is to achieve a reasonable coordination between technology and economy. The goal of the designer is to pursue the optimization of the relationship between the advanced nature, cost, and efficiency of the design technology program in the design.
