    In this research, the biodegradable film of poly(butylene adipate-co-terephthalate) (PBAT) would be used as the polymer matrix. The influence of zeolite (as the filler) type and content were investigated on the mechanical and barrier properties of film packaging. Zeolite was treated with (3-aminopropyl) trimethoxy silane. Films were produced by cast film extruder. Effects of different types of zeolite (5A and 13X) as well as zeolite loading (1-5 wt%) on mechanical properties and permeability of gases (oxygen, carbon dioxide and water vapor) of PBAT composites films have been extensively studied. Tensile properties of PBAT incorporated with zelolite 5A are higher than the one with zeolite 13X. In addition, increasing zeolite content into PBAT film is likely to improve YoungÕs modulus with the sacrifices of both tensile strength and percentage of elongation at break of PBAT film. For barrier properties, PBAT/zeolite 5A possessed lower permeation both of oxygen and carbon dioxide gases than PBAT/zeolite 13X. The effect of zeolite content plays a major role on oxygen and carbon dioxide permeability of composite films. PBAT/zeolite composite film could certainly extend the ripening period of Homthong bananas for approximately longer than one week. © 2020 Trans Tech Publications Ltd, Switzerland.

    The consumption of the plastic materials for packagings in everyday life has been increased. Low density polyethylene (LDPE) is a primary polymer for film packaging production. One of the innovative film developments is fragrant film with essential oil as additive. However, essential oil is easy to evaporate during process and thus _-cyclodextrin is required for retaining the essential oils. In addition, compatibilizer such as polyethylene-graft-maleic anhydride (PE-g-MA) is necessary to enhance the miscibility between polymer and additives. The effect of compatibilizer on morphological and mechanical of LDPE thin films incorporated with sweet basil oil is investigated. The _- cyclodextrin, sweet basil oil and PE-g-MA as compatibilizer are compounded with LDPE using twin-screw extruder. Miscibility of LDPE and _-cyclodextrin is studied by Fourier transform infrared spectroscopy. It is confirmed that interaction between _-cyclodextrin and PE-g-MA has taken place. Films are produced by cast-film extruder and then are characterized by universal testing machine. Young's modulus, tensile strength and elongation at break of LDPE film with sweet basil oil has been increased compared with neat LDPE film. © CCM 2020 - 18th European Conference on Composite Materials.

    Preparation and characterization of PET/SEBS incorporated with organomontmorillonite
    (IOP Publishing Ltd, 2020) Poonsub Threepopnatkul; Phakawan Thinsoongnoen; Pattaraporn Misut; Siriluk Autama; Chanin Kulsetthanchalee; P.

    This study is focused on the characterization of polyethylene terephthalate (PET)/Styrene-Ethylene-Butylene-Styrene (SEBS)/Organomontmorillonite (OMMT) blends. SEBS-g-MA is used as compatibilizer and SEBS is the impact modifier at 30 %wt. The compounds were blended by twin-screw extruder and molded for test specimen by injection molding. The effect of OMMT types (Cloisite15A and Cloisite30B) and contents (1 and 3 %w/w) on properties of PET blends with SEBS and SEBS-g-MA were investigated. The PET composites incorporated with Cloisite15A had higher impact strength and %elongation at break whereas lower tensile strength than the one with Cloisite30B. Comparing with PET/SEBS/SEBS-g-MA blends, adding OMMT into PET/SEBS/SEBS-g-MA would increase thermal property. However, it had no significant changes with higher OMMT. %Crystallinity of PET would be increased with OMMT contents. PET/SEBS/SEBS-g-MA had lower %LOI but higher burning rate compared with PET. However, the addition of OMMT could improve flame retardant properties of PET blends. Addition of Cloisite15A and Cloisite30B into PET/SEBS/SEBS-g-MA increased %LOI. From UL 94 tests, polymer composites could be classified in HB class. The burning rate of polymer composites was decreased with increasing OMMT due to decomposition of OMMT act as a barrier to inhibit combustion. © Published under licence by IOP Publishing Ltd.
