Vinyl polymers are generally considered resistant to biodegradation, with some exceptions. Their biodegradation requires an oxidation process, and most biodegradable vinyl polymers contain readily oxidizable functional groups. However, polyvinyl alcohol (PVA) is an exception and can undergo biodegradation relatively easily. Studies have shown that PVA biodegradation occurs under the influence of the soil bacterium Pseudomonas. […]
Polymers are large molecules composed of repeating subunits called monomers, and their unique properties make them widely used in various industrial and biomedical applications. However, the accumulation of non-biodegradable synthetic polymers in the environment has become a major concern. The development of biodegradable polymers, therefore, has become an active area of research in recent years. […]
Biopolymers are naturally occurring polymers that are formed under natural conditions during the growth cycles of all organisms. They are formed within cells through complex metabolic processes. Biopolymers are also known as natural polymers, and the most interesting for materials applications are cellulose and starch. However, there is an increasing interest in more complex hydrocarbon […]
Tapioca starch is a natural polymer that can be used as a raw material for producing bio-based products such as bio-resins. It has been found to have good potential as a substitute for synthetic resins due to its abundance, low cost, and renewability. Tapioca starch-based bio-resins can be produced through various methods, including thermal processing, […]
Bio-resin is a type of resin that is made from renewable or biodegradable materials, such as plant-based sources like corn starch, soybeans, sugarcane, and vegetable oils. Unlike traditional petroleum-based resins, bio-resins are considered to be more environmentally friendly because they are made from renewable resources and can biodegrade under certain conditions. Bio-resins are used in […]
Resin, a solid or highly viscous substance, finds its place in various industries as a versatile material. Whether synthetic, semi-synthetic, or naturally occurring, resins play a crucial role in applications ranging from adhesives and coatings to composites and molding. Diverse Forms and Origins Resins, arising from chemical reactions between compounds, manifest in liquids, powders, gels, […]
The development of food packaging from starch-based materials has gained considerable attention in recent years due to the increasing demand for sustainable packaging solutions. Starch-based materials offer several advantages over traditional petroleum-based packaging materials, such as biodegradability, compostability, and renewability. This article will discuss the advantages and disadvantages of using starch-based materials for food packaging […]
Starch, a natural polymer derived from plants, has emerged as a promising candidate for food packaging materials. Its non-toxic nature and abundance in nature contribute to its appeal, positioning it as a sustainable alternative to traditional packaging materials. However, as with any material, starch-based packaging comes with its own set of advantages and challenges, demanding […]
Active and intelligent packaging are two concepts that are transforming the way we think about packaged foods. Active packaging is a process in which active substances, such as antioxidants and antimicrobial agents, are incorporated into packaging materials to enhance the quality of the food and prolong its shelf life. These substances are either added during […]
Unveiling the Essence of Packaging in the Food Industry Packaging isn’t just about containment; it’s a multifaceted tool crucial for safeguarding, communicating, and enhancing consumer convenience around food products. However, the complexity of these products demands more than mere containment—it requires protection against lurking threats like microbes and chemicals. The key lies in the careful […]
