Ingeniería forense de materiales poliméricos avanzados. Parte III- Biodegradación de envasado termoformado rígido de PLA bajocondiciones industriales de compostajePublicada el 18/04/2016

Publication date: 18 April 2016 Source: Waste Management Author(s):Marta Musio, Wanda Sikorska, Grazyna Adamus, Henryk Janeczek, JozefRichert, Rafal Malinowski, Guozhan Jiang, Marek Kowalczuk This paperpresents a forensic engineering study on the biodegradation behaviour ofprototype packaging thermoformed from PLA-extruded film and plain PLAfilm under industrial composting conditions. Hydrolytic degradation in waterwas conducted for reference. The effects of composting duration onchanges in molar mass, glass transition temperature and degree ofcrystallinity of the polymeric material were monitored using gel permeationchromatography (GPC) and differential scanning calorimetry (DSC).

Efecto sinérgico de nanoestructuras de celulosa y lignina ensistemas a base de PLA para envasado antibacteriano dealimentosPublicada el 04/04/2016

Publication date: 4 April 2016 Source:European Polymer JournalAuthor(s): W. Yang, E. Fortunati, F. Dominici, G. Giovanale, A. Mazzaglia,G.M. Balestra, J.M. Kenny, D. Puglia Ternary polymeric films based onpoly (lactic acid), obtained dispersing cellulose nanocrystals (CNC) andlignin nanoparticles (LNP) at two different amounts (1 and 3% wt.),respectively in neat PLA and glycidyl methacrylate (GMA) grafted PLA (g-PLA), were produced by melt extrusion. Thermal, optical and mechanicalproperties, as well as the morphologies of CNC and LNP reinforced PLAnanocomposites, were investigated. Results from UV-Vis characterizationhave confirmed a synergic effect of LNP and CNC based nanostructures interms of transparency and UV light blocking capability.

Influencia de las condiciones de procesamiento en elcomportamiento morfológico, térmico y degradativo denanocompuestos a base de poli (3-hidroxibutirato) y arcillamodificadaPublicada el 29/02/2016

The effect of processing conditions (casting and extrusion) and plasticization on the disintegrability in composto f o rgan i ca l l y mod i f i ed c l ay po l y (3 -hyd roxybu ty ra te ) nanocompos i t es was s tud ied .Tributylhexadecylphosphonium bromide (TBHP) was used as organic modifier. As revealed by WAXS andTEM observations, intercalated nanobiocomposites with clay stacks and some individually dispersed plateletswere obtained. The melting temperature of the neat PHB diminished with the addition of plasticizer, thusbroadening the processing window. Biodegradation test revealed that while the clay slows down thedegradation rate, the plasticizer increases the degradation of the samples, reaching a similar final percentageof disintegrability when both plasticizer and clay were added in the formulation.

Proesamiento, envasado y almacenamiento de productos a basede tomate: Influencia del contenido de licopenoPublicada el 29/02/2016

According to several epidemiological studies, the lycopene content oftomato and tomato-based products is related to a variety of health benefits.This has sparked interest in knowing the effect of processing and storageof tomato products on this carotenoid, in order to preserve it duringmanufacturing and distribution till consumption. Furthermore, in the lastfew years special attention has been paid to the changes of all-trans andcis-isomers of lycopene during processing and storage. In fact, cis-isomershave shown higher health-promoting properties than all-trans isomers.Heat, light, oxygen, food matrices, and ingredients such as oil are factorsthat have an important effect on the main lycopene degradation reactions:isomerization and oxidation.

Nueva clase de material biodegradable para envasadoPublicada el 24/02/2016

Publication date: 24 February 2016 Source: Composites Part B:Engineering Author(s): Stanislaw Frackowiak, Joanna Ludwiczak, KarolLeluk, Marek Kozlowski Reducing waste amount from plastic packagingmaterials is in the scope of interest of many scientific groups in the world.One of the most important biodegradable polyesters with good mechanicalproperties, high transparency and good processability is poly(lactic acid). Itcan be modified with various additives (plasticizers, chain extenders etc.)or by preparing blends with other polymers. Such blends can be furthermodified by addition of functional fillers in order to improve final properties.In the paper an anisotropic polymer composite was developed based onpoly(butylene succinate)/poly(lactic acid) matrix with carbon nanotubes asa filler.

Nanocompuestos organomodificados de montmorillonita ypoli(3-hidroxibutirato-co-3-hidroxihexanoato) para potencialesaplicaciones en envasado de alimentosPublicada el 19/02/2016

Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) is a versatile,b iobased and b iodegradable copolymer f rom the fami ly ofpolyhydroxyalkanoates. This study aims to further ameliorate its propertiesin order to enhance its applicability for food packaging purposes throughpreparat ion of organomodif ied montmori l loni te c lay (OMMT)nanocomposites. Nanocomposites based on pure PHBHHx as well ascommercial PHBHHx granulate, after a previous dry-mixing with OMMT inconcentrations of 1, 3, 5 and 10 wt%, were prepared using melt blendingand compression molding.

Alimentos refrigerados: Envasado al vacíoPublicada el 01/01/2016

Publication date: 2016 Source :Encyclopedia of Food and Health Author(s): M. Rossi Eliminating the presenceof oxygen in contact with foodstuffs, and preventing further access of oxygen during storage, prolongs thefreshness of foodstuffs. Vacuum packaging is one of the simplest and most widely used systems to achievethis objective. This type of packaging has enjoyed increasing success since the late 1950s, in parallel with thedevelopment of the technology of plastics owing also to the changes in the distribution chain of perishablefoods requiring increased hygiene and storage life.

Low densitypolyethylene and linear low density polyethylene are the most common materials used. Plastic films can beproduced using either the blown film or cast film processes. Coextrusion and lamination are used to producefilms containing more than one plastic layer or combining plastic with paper or foil. Coating is also used toprovide improved properties such as enhanced barrier.

A package having a lid seated on a base where the edge of the seated lidis generally inaccessible due to contours in the base, and where the edgeis made accessible by a tamper-evident tab arrangement. The baseincludes a tamper-evident tab and a fixed tab disposed on a flangeextending about the base. The tamper-evident tab is joined to the base onopposite ends by a breakable land and a permanent land. The tamper-evident tab is movable by breaking the tamper-evident tab free from thebase on one end by breaking the breakable land and bending the tamper-evident tab out of the way about the permanent land to provide access tothe peripheral edge of the lid.

Extrusión: Entendiendo la separación de barreraPublicada el 22/02/2016

Since barrier screws are being used in so many applications, it’s importantto understand all the variables controlling their performance. One of thoseis the barrier gap. I see all kinds of variations that often do not match theother features of the screw design. I assume many designers have theirown calculation to determine the gap, as literature on the subject offerslittle in the way of guidelines.

Extrusión: La relación entre entrada y salidaPublicada el 12/02/2016

When pellets fall into the first screw channel in the feed zone, the angledflights of the screw push them downstream, as well as around the barrelcircumference. The amount conveyed depends on their size and shape(bulk density), how much they stick to the barrel and how well they slip onthe screw root. More sticking to the barrel and less sticking to the rootmean more forward-conveying per turn.
