Mechanical Characterization Of Expanded Polystyrene Spheres Embed Sandwich Composites For Packaging Applications, Maheswaran R, Arockia Reemas S
Mechanical Characterization Of Expanded Polystyrene Spheres Embed Sandwich Composites For Packaging Applications, Maheswaran R, Arockia Reemas S
Journal of Applied Packaging Research
This paper addresses on study of development of new packaging material comprising Expanded Polystyrene Spheres (EPS) embedded epoxy polymer based sandwich composites with aluminium skin. The density of the packing material is controlled by varying the volume of embedded spheres. In this study, the Flexural and Compression performance of Expanded Polystyrene Spheres (EPS) embedded polymer based sandwich composites with aluminium skin are investigated. The EPS volume percent in the core is 25% with epoxy matrix which makes the the density less than 1 g/cm3 for the composite. The fabricated Sandwich Composite are very light weight, the density is less than …

The micro- and macrostructural changes occurring in multi-layered substrates during three-dimensional forming were studied by atomic force microscopy (AFM), scanning electron microscopy (SEM) and optical analyses. Particular attention was paid to heat-induced deformations at the interface between of polymeric coating layer and the paperboard. With excessive heat transfer, occasional delamination of polyethylene terephthalate (PET) coating from the paperboard was observed. The mechanism behind delamination was studied in detail in-situ with an AFM at temperatures relevant to the converting process. Based on the analysis, the delamination could partially be linked to the widening of the initially-existing nano-scale cracks at the coating-paperboard …
Polyestyrene And Low Density Polyethylene Oregano´S Essential Oil Functionalization For Possible Antimicrobial Active Packaging Applications, Edgar Díaz-Acosta, Claudia Rodríguez-González, Laura Valencia-Gómez, Santos Adriana Martel-Estrada, Maria Hernández-González, Hortensia Reyes-Blas, Imelda Olivas Armendáriz 1761524

Low density polyethylene (LDPE) and polystyrene (PS) samples were functionalized with oregano´s essential oil (OEO) for possible antimicrobial packing applications. Different concentrations of OEO were used (0.5-1.5 % v/v). Polymers were UV light irradiated during 60 min to improve the OEO adhesion through the polar groups (COOH, OH or COO-) generation on their surface. The effect of OEO different concentration on their antimicrobial activity, mechanical properties and cytotoxicity of the functionalized polymers were analyzed. All functionalized samples showed antimicrobial activity against Gram positive and Gram negative bacteria and this activity increased with OEO concentration. The addition of OEO did not …
Experimental Tests And Numerical Simulations For Failure Investigation On Corrugated Boxes Used On Household Appliance Packaging, Diego Fernandes Rodrigues, José Carlos Pereira
Experimental Tests And Numerical Simulations For Failure Investigation On Corrugated Boxes Used On Household Appliance Packaging, Diego Fernandes Rodrigues, José Carlos Pereira
Journal of Applied Packaging Research
Packages made of corrugated paper are fundamental to the protection, transportation and handling of the appliance product market. During the storage and sales stages of a product, the package must resist compressive loads in different directions beyond moderate impacts. In this context, the objective of this work is to develop and implement a post-processor that allows the simultaneous analysis of two of the most common failure modes of packages made of corrugated paper: failure due to tensile or compressive stress limit, and failure due to local buckling, when the buckling of the faces of the corrugated paper between two peaks …

Journal of Applied Packaging Research
The aim of this study was to create a completely hydrosoluble edible films based on biopolymers that can be used as packaging material for powdered foods.10 edible films were obtained from various mixtures of hydrocolloids (agar, starch, sodium alginate) plasticized with glycerol and water. To assess their solubility, it was used the Peleg model which confirmed that increasing the temperature of the hydration medium, increases the water absorption rate. The sample obtained from agar and starch was less hydrophilic than sample with a high amount of sodium alginate, which was completely soluble after 3 minutes maintenance in 20° water. To …

Modified Atmosphere Packaging (MAP) has been widely used as an effective way to preserve foods. Fresh produce, meat and meat products, seafood, and dairy products can benefit from modified gaseous atmospheres, which are usually achieved by reducing oxygen and increasing carbon dioxide concentrations, within limits, defined by product tolerances. MAP of fresh produce is particularly challenging because products are living and respiring. Respiration rates depend on several factors including temperature, oxygen, and carbon dioxide concentrations. Balancing package permeation with respiration is challenging, often due to limited selection of practical packaging materials. Failing to remain within tolerance limits of products leads …
Measuring The Creep Behaviour Of Corrugated Board By Cascade And Individual Test Rig, Viktoria Köstner, Jörg B. Ressel, Bernd Sadlowsky, Péter Böröcz
Measuring The Creep Behaviour Of Corrugated Board By Cascade And Individual Test Rig, Viktoria Köstner, Jörg B. Ressel, Bernd Sadlowsky, Péter Böröcz
Journal of Applied Packaging Research
In this paper static and quasi-static test are conducted to determine the creep behaviour of corrugated board. This study shows a possible way to take the real loads occurring in container shipping into account. The aim of the measurements is to develop a new test option, which is in keeping with the loads occurring. Two test rigs have been developed and constructed for this purpose. These make it possible to measure the creep of corrugated board extremely precisely over a longer period in the aspect of climate chamber size and relative humidity (RH) distribution in the chamber. To increase the …

Solid waste generation is estimated to increase from 1.3 billion to 2.2 billion tons by 2025, causing environmental, social, and consequently public health problems. The biggest problem in this regard involves the inadequate disposal of waste, and in emerging countries like Brazil, it is sorted less waste for recycling or composting. In this context, plastic packaging is more complex due to the high polymer composition, as well as low recycling rates. Bioplastics appear as alternatives because they are mostly biodegradable. Given the various functions of packaging and a systematic review of the literature, the aim of this study was to …
