The corrugated box was designed taking account of load condition that corrugated box experiences. In this context, considered vital parameters like safety, moisture content and nature of load those influence the performance of the corrugated box. With the help of this simple and practical design approach, the suitability of the design for the long transportation was arrived at and importance of influencing parameters was discussed. Keywords -; Corrugated box, carton, corrugated box damage, transportation I. INTRODUCTION II. CARTON BOX: The prime objective of any industry is to sell the goods in a good condition to the customers. Right quality of goods develop customer satisfaction and their loyalty. Even though so much of care is taken during the production of goods, improper packing of goods and subsequent transportation can result in damage of goods. To avoid this kind of situation one need to address the packing stability and its suitability in conjunction with mode of transportation chosen and the product nature i.e. fragile, hazardous etc.. Packaging may be looked in different ways, and it may be described based on the product that is going to be packed. Categorization of the packaging is as follows Corrugated boxes are industrially prefabricated boxes, primarily used for packaging goods and materials. Specialists in industry often use the term cardboard because it does not denote a specific material A. Global Trends of Corrugated Box: World demand for corrugated boxes is forecast to increase by 4.2 % per year to 234 billion square meters in 2017, slightly outpacing real (inflation-adjusted) gains in GDP(1). Primary packaging is the material that first envelops the product and holds it. This usually is the smallest unit of distribution or use Growth factors include rising industrial activity, and the package is in direct contact with the contents. particularly in the manufacturing sector, which often requires corrugated packaging to protect and transport Secondary packaging is outside the primary packaging, goods. In addition, ongoing developments in small flute and used to group primary packages together. high-quality graphic board allow corrugated boxes to Tertiary packaging is used for bulk handling, warehouse penetrate traditional folding carton applications, especially storage and transportation. The most common form is a in the developed world. Greater interest in corrugated palletized unit load that packs tightly into containers packaging as a point-of-sale display in retail applications will also boost demand for value-added boxes. The fastest increase in demand for corrugated boxes will The primary packaging category was chosen for our study i.e. occur in developing regions; both Asia/Pacific and the to arrive an optimal design of corrugated box. Africa/Mideast regions will both outpace the global average.

Moisture factor Load Conversion factor Safety factor Moisture Factor: Because the board material is hygroscopic in nature, the strength properties of corrugated board products are very much dependent on the relative humidity. More precisely, it is the actual moisture content in the corrugated material that affects its strength. The increase in moisture content in the material breaks the bonds between cellulose fibres, affecting the mechanical properties. Recent research has shown that, as the moisturecontent of corrugated package is increased from III. ARRIVING AT OPTIMAL DESIGN: 7.7% to 16.4%, its compressive strength got reduced by 52%(3,4, and 5).

Corrugated fiberboard is comprised of linerboard and heavy paper medium. Linerboard is the flat, outer surface that adheres to the medium. The medium is the wavy, fluted paper between the liners. Both are made of a special kind of heavy paper called !containerboard. Board strength will vary depending on the various linerboard and medium combinations.! • Single Face: Medium glued to 1 linerboard; flutes exposed! • Single Wall: Medium between 2 liners! • Double Wall: Varying mediums layered between 3 liners! !• Triple Wall: Varying mediums layered between 4 liners! !Flute Facts! !Corrugated board can be created with several different flute profiles. The five most common flute profiles are:! • A-Flute: Original corrugated flute design. Contains about 33 flutes per foot.! • B-Flute: Developed primarily for packaging canned goods. Contains about 47 flutes per foot and measures 1/8" thick! • C-Flute: Commonly used for shipping cartons. Contains about 39 flutes per foot and measures 5/32" thick! • E-Flute: Contains about 90 flutes per foot and measures 1/16" thick! • F-Flute: Developed for small retail packaging. Contains about 125 flutes per foot and measures 1/32" thick! • Generally, larger flute profiles deliver greater vertical compression strength and cushioning.

    Damping Package Design Using Structural Corrugated Board

    RESEARCH ARTICLE Damping Package Design Using Structural Corrugated Board PREFACE API 2015 Qi Zhang Katsuhiko Saito Kobe University Kobe University [email protected] [email protected] Katsushige Nagaoka TSK Coporation [email protected] ABSTRACT Packaging is designed to protect products from shock and vibration during transport. In recent years, paper cushioning materials, such as corrugated board and pulp molded packaging, are being increasingly used because they are environmentally friendly and easy to recycle. However, because no efficient packaging-design method yet exists for paper cushioning material, packaging engineers must rely on previous experience and the so-called trial-and-error method to design packaging. One reason for this situation is that, for most cases, the paper cushioning material used for protective packaging has a complicated structure and deforms after being subjected to repetitive shock and vibration. To address this shortcoming, we propose a damping design method for corrugated-board packaging that includes shock-absorbing and vibration damping elements. To verify that the resultant packaging functions as intended, we test three types of packaging in the following way: First, we use an existing design method to create cushioned packages and examine them via free-fall drop tests. Next, to test the robustness of packaging against vibration (i.e., for packaging destined for various modes of transport), we study the three packaging types by subjecting them to (i) vibration-only tests and (ii) drop-plus-vibration tests. For vibration-only tests, the packaging with highest static stress gives the best result, its “vibration fatigue” accounts for approximately 52% of the worst result given by packaging with the lowest static stress.

    Guidelines on Stability Testing of Cosmetics

    COSMETICS EUROPE: GUIDELINES ON STABILITY TESTING OF COSMETIC PRODUCTS ALL RIGHTS RESERVED TO CTFA AND COSMETICS EUROPE MARCH 2004 03/094 - MC GUIDELINES ON STABILITY TESTING OF COSMETIC PRODUCTS March 2004 I. GENERAL CONSIDERATIONS 1. INTRODUCTION General The purpose of stability testing cosmetic products is to ensure that a new or modified product meets the intended physical, chemical and microbiological quality standards as well as functionality and aesthetics when stored under appropriate conditions. Because the development cycle of cosmetic products is relatively short, and also, in order that the testing activity does not become economically disproportionate in view of the multitude of product launches each year, each manufacturer must have at their disposal tests that are adapted to their activity. Each manufacturer should design their stability testing program such that it is reasonable and efficiently addresses the testing required. This document aims to set out guidelines in order to predict and assure the stability of products in the market place. Its purpose is to aid manufacturers of cosmetic products in the selection and the refinement of the appropriate stability tests. Although this guideline can provide a helpful starting point, it is important that manufacturers carefully evaluate new products and technologies and, where appropriate, adapt their testing to reflect differences between product types and formulations. However, all methods assuring the final stability of a cosmetic product against the categories cited in paragraph below, if it is at least equivalent to the recommendations of the following chapters, are considered as valid. Procedures must be put in place and documented within the manufacturer’s internal system.
