  • Extrusion Foaming of Bioplastics for Lightweight Structure in Food Packaging
    EXTRUSION FOAMING OF BIOPLASTICS FOR LIGHTWEIGHT STRUCTURE IN FOOD PACKAGING A thesis submitted for the degree of Doctor of Philosophy by Sitthi Duangphet School of Engineering and Design Brunel University December 2012 i Abstract This thesis reports the systematic approaches to overcome the key drawbacks of the pure PHBV, namely low crystallisation rate, tensile strength, ductility, melt viscosity, thermal stability and high materials cost. The physical, mechanical, thermal, and rheological properties of the pure PHBV were studied systematically first to lay a solid foundation for formulation development. The influence of blending with other biopolymers, inclusion of filler, and chain extender additives in terms of mechanical properties, rheology, thermal decomposition and crystallization kinetics were then followed. Creating lightweight structures by foaming is considered to be one of the effective ways to reduce material consumption, hence the reduction of density and morphology of PHBV-based foams using extrusion foaming technique were studied comprehensively in terms of extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content. The material cost reduction was achieved by adding low-cost filler (e.g. CaCO3) and reduction of density by foaming. The thermal instability was enhanced by incorporation of chain extender (e.g. Joncryl) and blending with a high thermal stability biopolymer (e.g. PBAT). The polymer blend also improved the ductility. Adding nucleation agent enhanced the crystallization rate to reduce stickiness of extruded sheet. The final formulation (PHBV/PBAT/CaCO3 composite) was successfully extruded into high quality sheet and thermoformed to produce prototype trays in an industrial scale trial. The effect of the extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content are correlated to the density reduction of the foams.

Among biopolymers, blends made of poly(lactide) (PLA) and poly(butylene-adipate-co-terephthalate) (PBAT) prove to have adequate performances for food packaging applications. Therefore, the present work deals with the production and the characterization of blown films based on PLA and PBAT blends in a wide range of compositions, in order to evaluate their suitability as chilled and frozen food packaging materials, thus extending their range of applications. The blends were fully characterized: they showed the typical two-phase structure, with a morphology varying from fibrillar to globular in accordance with their viscosity ratio. The increase of PBAT content in the blends led to a decrease of the barrier properties to oxygen and water vapor, and to an increase of the toughness of the films. The mechanical properties of the most ductile blends were also evaluated at 4 C and 25 C. The ◦ − ◦ decrease in temperature caused an increase of the stiffness and a decrease of the ductility of the films to a different extent, depending upon the blend composition.

  • High Performance Ester Plasticizers
    High Performance Ester Plasticizers Abstract Traditional elastomer polymers, such as nitrile, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, have for years used moderate- to low- performance ester plasticizers. However, longevity requirements for rubber articles made from these elastomers have created a need for higher-performance ester plasticizers. With the increasing high-temperature demands required by automotive, other elastomers such as acrylic, high-saturated nitrile, epichlorohydrin and ethylene propylene diene monomer EPDM are replacing the more traditional elastomers. Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers. The test data will include heat aging, extraction by hydrocarbons and low-temperature as molded after aging. The information provided indicates that the permanence of the plasticizer after these various agings is the key to the retention of physical properties. Introduction End uses for elastomer compounds are quite diverse, but they can be loosely categorized as being either general performance or higher performance applications. Each of these performance categories requires a different set of considerations in terms of compounding with ester plasticizers. An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one. Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length.

The packaging industry is the largest and growing consumer of synthetic plastics derived from fossil fuels. Food packaging plastics account for the bulk of plastic waste that are polluting the environment. Additionally, given the fact that petroleum reserves are finite and facing depletion, there is a need for the development of alternative materials that can serve the same purpose as conventional plastics. This paper reviews the function of packaging materials and highlights the future potential of the adoption of green materials.

  • And Poly(Butylene Adipate) - Quantitative Determination of Degradation Products and Application As PVC Plasticizers
    Poly(butylene succinate) and Poly(butylene adipate) - Quantitative Determination of Degradation Products and Application as PVC Plasticizers Annika Lindström AKADEMISK AVHANDLING som med tillstånd av Kungliga Tekniska Högskolan framlägges till offentlig granskning för avläggande av teknisk licentiatexamen fredagen den 11 februari 2005, kl. 10.15 i Salongen, KTHB, Kungliga Tekniska Högskolan, Osquars backe 31, Stockholm. Avhandlingen försvaras på svenska. Abstract A solid phase extraction (SPE) method was developed for simultaneous extraction of dicarboxylic acids and diols formed during hydrolysis of poly(butylene succinate), PBS, and poly(butylene adipate), PBA. The developed SPE method and subsequent GC-MS analysis were used to extract, identify and quantify low molecular weight products migrating from linear and branched poly(butylene adipate) (PBA) and poly(butylene succinate) (PBS) during aging in aqueous media. The combination of SPE and GC-MS proved to be a sensitive tool, able to detect small differences in the degradation rate during early stages of hydrolysis before any significant differences were observed by weight loss and molecular weight measurements. The detected low molecular weight products included monomers i.e. adipic acid and 1,4-butanediol for the PBA polymers and succinic acid and 1,4-butanediol for PBS. Several dimers and trimers i.e. hydroxybutyl adipate, hydroxybutyl succinate, di(hydroxybutyl) adipate, di(hydroxybutyl) succinate and hydroxybutyl disuccinate were also detected. Best extraction efficiency for 1,4-butanediol and succinic acid was achieved with a hydroxylated polystyrene-divinylbenzene resin as solid phase. Linear range for the extracted analytes was 1-500 ng/µl for adipic acid and 2-500 ng/µl for 1,4-butanediol and succinic acid.

Received: 25 November 2020; Accepted: 9 December 2020; Published: 12 December 2020 Abstract: Bio-based polyol polyesters are biodegradable elastomers having potential utility in soft tissue engineering. This class of polymers can serve a wide range of biomedical applications. Materials based on these polymers are inherently susceptible to degradation during the period of implantation. Factors that influence the physicochemical properties of polyol polyesters might be useful in achieving a balance between durability and biodegradability. The characterization of these polyol polyesters, together with recent comparative studies involving creative synthesis, mechanical testing, and degradation, have revealed many of their molecular-level differences. The impact of the polyol component on the properties of these bio-based polyesters and the optimal reaction conditions for their synthesis are only now beginning to be resolved.

  • Use of Thermoplastic Starch in Poly(Lactic Acid)/Poly(Butylene Adipate-Co-Terephthalate) Based
    Use of thermoplastic starch in poly(lactic acid)/poly(butylene adipate-co-terephthalate) based nanocomposites for bio-based food packaging by Pavan Harshit Manepalli B.Tech, Indian Institute of Technology, Kharagpur, 2012 M.S., Kansas State University, 2014 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Department of Grain Science and Industry College of Agriculture KANSAS STATE UNIVERSITY Manhattan, Kansas 2019 Abstract Poly(lactic acid) (PLA) is the most common bio-based & compostable polymer available commercially that is cost competitive and combines a range of desirable properties like melt processability, high strength and modulus. The films made from this aliphatic polyester tend to be brittle which can be overcome by blending PLA with another bio-based polymer with high flexibility poly(butylene adipate-co-terephthalate) (PBAT), but the resultant blend is only biodegradable in composting conditions. The primary focus of this study was incorporation of thermoplastic starch (TPS) in PLA/PBAT blends to increase the rate of biodegradability and decrease the cost. In the first part of this study, as a preliminary step only PLA/PBAT blends were investigated along with nanofiller nanocrystalline cellulose (NCC) as a nanofiller for enhancing mechanical and barrier properties. Melt extrusion was used for preparation of nanocomposites and 200 microns thick films were formed by melt pressing. PBAT enhanced elongation but NCC did not have any positive impact on the mechanical and barrier properties of the nanocomposites as NCC was aggregated in the polymer matrix due to the difference in polarity based on the hydrophilic nature of the nanofiller and hydrophobic nature of the polymer matrix.
