These changes have dictated that new methods and techniques be explored as possible replacements for tradi- ● tional packaging practices. This handbook provides packaging criteria, materials, and test information for guidance in the design, development, and fabrication of packaging within the framework of the DOD packaging policy. ✎ ●✎✎ iii Downloaded from http://www.everyspec.com MIL-HDBK-772 30 March 1981 CONTENTS Page o Paragraph 1.

MINIMUM SAMPLE SIZE NEEDED TO CONSTRUCT CUSHION CURVES BASED ON THE STRESS-ENERGY METHOD A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Packaging Science by Patricia Dione Guerra Marcondes May 2007 Accepted by: Dr. Duncan O. Darby, Committee Chair Mr. Gregory S. Batt Dr. Hoke S. Hill, Jr. Dr. Matthew Daum ABSTRACT Cushion curves are graphical tools used by protective package designers to evaluate and choose foamed cushioning materials. Thousands of samples and hundreds of laboratory hours are needed to produce a full set of cushion curves according to the ASTM procedure D 1596. The stress-energy method considerably reduces the number of samples needed to construct cushion curves for closed-cell cushioning materials. Consequently the laboratory and data analysis time are reduced as well. The stress-energy method was used to find the minimum sample size needed to construct cushion curves for closed-cell cushioning materials.

    LAPPEENRANTA UNIVERSITY OF TECHNOLOGY LUT School of Energy Systems LUT Mechanical Engineering Yang Gao RESEARCH ON PROPERTIES AND DESIGN METHODS OF CUSHION PACKAGING MATERIALS FOR CONSUMER ELECTRONICS Examiners: Professor Kaj Backfolk D.Sc. Katriina Mielonen ABSTRACT Lappeenranta University of Technology LUT School of Energy Systems LUT Mechanical Engineering Yang Gao Research on Properties and Design Methods of Cushion Packaging Materials for Consumer Electronics Master’s thesis 2018 126 pages, 81 figures, 14 table Examiners: Professor Kaj Backfolk Ph.D. Katriina Mielonen Keywords: Packaging Material, Cushion Structure, Nonlinear, Simulation, Transport package is very important in the logistic. The main tasks of transport package are to select proper cushioning material and obtaining reasonable structure. For the consumer electronics packaging, EPS is the cushioning material used widely nowadays. But it cannot degrade and recycle, so lots of new cushioning materials appear. To use these new types of materials widely, it needs to do a lot of researches. This paper mainly discussed the property of the new cushioning materials and its design methods by simulation analysis and experimentation. Thus the cushion design methods of transport package are suggested. The paper, firstly, studied the property of new cushioning materials through dynamic test, discussed the novel way to determine the cushioning curves. Then, the paper studied the dynamic response of the nonlinear materials to judge performance of nonlinear packaging and utilized the software of finite element analysis to simulate packaging drop response. Finally, the design methods of the cushion packaging are suggested. ACKNOWLEDGEMENTS This master thesis was carried out in Lappeenranta University of Technology, Finland. This work was lasting for long time due to my working reason, but finally I finished it.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. In some electronic products and sculpture crafts, there are possibly vulnerable elements that can be idealized as cantilever beam type, failure of which will certainly lead the whole product to lose function. Based on the critical component of cantilever beam type, a nonlinear coupling dynamics model between the critical component and the item was established. The computing procedure of the model was designed using finite difference scheme. A numerical example shows that the acceleration changes notably withthe length of the critical component, and the cantilevered end of the critical component is liable to be damaged, because the dynamic stress there is the largest. In this case, the maximum acceleration just cannot serve as the damaged criterion of the packaged goods, only with the maximum stress value.

  • Comparison of Package Cushioning Materials to Protect Post-Harvest Impact Damage to Apples
    Comparison of Package Cushioning Materials to Protect Post-harvest Impact Damage to Apples B. Jarimopas Department of Agricultural Engineering, Kamphaengsaen Engineering Faculty, Kasetsart University S. P. Singh School of Packaging, Michigan State University, East Lansing, MI, USA S. Sayasoonthorn The Postgraduate and Research Development Project of Postharvest Technology, Graduate School, Kasetsart University, Kamphaengsaen, Nakohnpathom,Thailand Jagjit Singh Industrial Technology, OCOB, Cal Poly State University, San Luis Obispo, CA 93407, USA ABSTRACT Damage to fruits and vegetables continues to be a big challenge as global markets become a reality. Worldwide distribution of sensitive produce is faced with various levels of impacts from shipping and handling. Despite a variety of packaging options available today, bruising damage is commonplace for post-harvest apples throughout the supply chain. The major sources of bruising are compression, impact or vibration forces. Understanding where these forces occur can help reduce this type of mechanical damage to apples. The purpose of this study was to investigate the impact characteristics of foam net and corrugated board when applied as wrapping for individual apples. Two grades (count numbers 80 and 100) of “Fuji” cultivar apples imported to Thailand from China were studied. A simple ballistic pendulum test device was developed to measure bruise volume to impact energy relationship. A linear relationship for both types of apples was observed. Bruise volume occurrence probability and impact energy relationship fitted by linear regression were created for cushioned and bare apples. Absorbed energy of various cushioning materials was also calculated under compressive forces. KEY WORDS: apple; ballistic pendulum; bruise volume; cushioning; impact energy INTRODUCTION This study focused on developing a simple methodology to compare the performance of cushion wrapping materials that can be used for impact-sensitive fruits and vegetables.

Jiang 3 1 Department of Industrial Engineering and Management, Ming Chi University of Technology, New Taipei City 24303, Taiwan 2 Yuen Foong Yu Packaging Inc., Taoyuan Plant, Taoyuan City 33849, Taiwan; [email protected] 3 Department of Industrial Management, National Taiwan University of Science and Technology, Taipei City 24301, Taiwan; [email protected] * Correspondence: [email protected]; Tel.: +886-2-2908-9889 Abstract: The application of corrugated paper to buffer packaging has increased with the rise of the circular economy. The dynamic buffer curve is the key to designing the buffer packaging structure but requires multiple testing by small- and medium-sized enterprises (SMEs) without resources. In this study, we propose drop testing to perform a fractional factorial experiment and establish a regression model of impact strength through experimental data. The analysis results show that static stress, falling height, and buffer material thickness are the key variables of impact strength, and an impact strength prediction model (R2 = 94.1%) was obtained. Model verification using the buffer package design of a personal computer showed that the measured values of impact strength fell within the estimated 95% confidence interval. These results indicate that SMEs can use the proposed analysis procedure to improve the design of corrugated paper using minimal resources. Citation: Wang, C.-C.; Chen, C.-H.; Jiang, B.C.
