Preparation and characterization of multilayer film incorporating oxygen scavenger

摘要: The polymeric films (A-F types) as the practical approach of functional packaging to improve quality and safety products were developed characterized concerning their optical, thermal, mechanical properties. They manufactured using a co-extrusion blow process for three-layer structure with core layer containing oxygen scavenging materials (OS1 or OS2) mixed HDPE LLDPE. % light transmission F film (LLDPE was much lower than that E OS1) LLDPE (the control). transparency reduced dramatically due good dispersion scavenger without agglomeration larger particle sizes those film, which can interrupt transmission. value (25.6%), indicates percentage crystallinity, (30.8%). Thermogravimetric analysis (TGA) samples showed residual in approximately 7–9% above residue film. Both values properties, such tensile & break strength elongation when compared Selected multi-layer incorporated 20%, 30%, 50% also evaluated efficiency. absorbing amounts all increased at almost same ratio material contents. effect slightly better consuming 6.10 mL/O2 per g after 30 days storage 23 °C 100% RH, because an resulted decrease uptake. Therefore, is preferred over other developing efficient
