“…The OTR of the PVA films incorporated with different concentrations of GTE was shown in Figure . The OTR of pure PVA film was 3.28 (cm 3 ·m −2 ·24 hr −1 ·0.1 MPa −1 ), which was similar to the previous findings (Lim et al, ; Wang et al, ). The OTR of PVA films incorporated with GTE decreased significantly with the increasing concentration of GTE from 0 to 2% ( p < .05), which indicated that the addition of the GTE to PVA films improved the oxygen barrier property.…”

Active packaging film with functions of moisture-absorbing and antioxidant activity was developed based on poly(vinyl alcohol) (PVA) incorporated with green tea extract (GTE). The effects of GTE concentrations of 0, 0.5, 1, 1.5, and 2% on the physical, structural, and antioxidant properties of PVA films were investigated. The PVA film containing 2% GTE had lower moisture absorbing efficiency relatively and better antioxidant activity through DPPH radical-scavenging ability experiment. A packaging system of GTE-incorporated PVA films was applied to package dried eel and quality of dried eel was evaluated during storage. The result showed that dried eel packed with GTE-incorporated PVA films showed lower weight change, peroxide value and TBARS value during storage than that packed without PVA films or with PVA films but no GTE. The PVA film containing 2% GTE showed the best quality protective effectiveness to prevent the dried eel from absorbing moisture and oxidizing of lipid. Practical applicationsPoly(vinyl alcohol) (PVA) is a synthetic polymer that is widely used in packaging applications because of its excellent film forming, biodegradability, good mechanical, and gas barrier properties.The present study evidenced that the PVA films incorporated with GTE showed good quality protective effectiveness to prevent the dried eel packed with these films from absorbing moisture and oxidizing of lipid. This active packaging film could be used as inner layer or intermediate layer in the composite packaging film system to improve the storage quality of moisture-sensitive and high-fat food. Based on this concept, the moisture-absorbing agents and antioxidant can be incorporated into the packaging structures to develop an active multifunctional food packaging material potentially to remove or reduce moisture inside the food packaging system instead of desiccants and preservative added in the food.

“…These groups can restrict the creation of hydrogen bonding with adjacent -OH groups, resulting in increased blend solubility, water uptake and permeability. As such, partialhydrolysis PVA is not preferred for packaging applications [48][49][50][51] . Roohani et al [48] compared thermal properties of full-hydrolysis and partial-hydrolysis PVA/cellulose nanowhisker (CNW) composite films.…”

“…Whilst pure PVA has a Tm of 230 º C, the value of Tg is known to depend on the degree of hydrolysis with values of 85 º C for 98-99% hydrolysed PVA and 58 º C for 87-89% hydrolysed PVA [62] . In general, the Tg of PVA decreases linearly with increasing relative humidity as a result of the plasticising effect of water on the PVA structure [49] . Holland and Hay [69] characterised the thermal degradation of PVA in solid and molten states.…”

This review exclusively addresses material systems primarily based on poly (vinyl-alcohol) (PVA), one of the most popular water soluble biopolymers, for their use in packaging applications with the primary objective of reducing petro-based plastic waste. In addition, some typical PVA blends and nanocomposites are discussed as comparative studies for material packaging. Structural characteristics, mechanical, thermal and barrier properties, in addition to biodegradation of these multiple material systems, are summarised in a systematic manner.Finally, associated fabrication processing methods together with the most popular theoretical models used for the permeability of PVA nanocomposites are also reviewed in detail.

The Effect of Coating Process and Additives on EVA Coated Tyvek^® for Gas Sterilizable Medical Packaging Applications

Tyvek®, as an ethylene oxide (EtO) gas sterile medical packaging material with a high‐gas permeation and serving as an excellent microbial barrier, must be coated with heat‐sealable adhesives to thermally seal various plastic packaging trays or films. Tyvek® sheet coated with heat‐sealable adhesives must have both porous structure and good sealing strength to various substrates. In this study, an acid pre‐coating method was distinctively introduced to minimize reactions between the blowing agent and acid during mixing, to resultantly generate ethyl vinyl acetate (EVA) layers with porous structure on Tyvek® sheets. To determine the feasibility of applying the as‐prepared coated Tyvek® as a sterile medical packaging material, we investigated the properties of the coating solution and coated Tyvek® as a function of process and additive composition. Finally, EtO gas sterilization tests were performed, and property changes in the coated Tyvek® were investigated. Properties of the coated Tyvek® were strongly dependent on the pre‐coating process and the composition of various additives. Pre‐coating with citric acid led to less of a reaction between citric acid and ammonium carbonate as a blowing agent during mixing and resulted in both good seal strength and air permeation for the coated Tyvek® sheets. The coated Tyvek® sheets, composed of a water‐based EVA emulsion solution with various additives, were not affected by the EtO sterilization process and yielded good resistance to humidity, EtO gas and vacuum cycles. The coated Tyvek® sheets prepared by applying an acid pre‐coating may be a promising candidate for gas sterilizable medical device packaging materials. Copyright © 2017 John Wiley & Sons, Ltd.
