Abstract

The invention provides an antibacterial environment-friendly packaging thin film and a preparation method thereof. The antibacterial environment-friendly packaging thin film is prepared from the following components in parts by weight: 5 to 10g of microcrystalline cellulose fiber, 5 to 10g of plant essential oil, 8 to 15g of an emulsifier and 60 to 80g of polyhydroxybutyrate-hydroxyvaleratepoly(3-hydroxybutyrate-co-3-hydroxyvalerate. The antibacterial environment-friendly packaging thin film provided by the invention is provided with the plant essential oil so that the antibacterial effect canbe realized and the shelf life of foods is prolonged; the poly(3-hydroxybutyrate-co-3-hydroxyvaleratepolyhydroxybutyrate-hydroxyvalerate with excellent performance including biocompatibility, high crystallization degree, low toxicity and the like is used as a matrix and the microcrystalline cellulose fibers are used as filler, so that the defects that the poly(3-hydroxybutyrate-co-3-hydroxyvaleratepolyhydroxybutyrate-hydroxyvalerate matrix has great brittleness, poor toughness and slow crystallization speed can be improved, and the mechanical performance and the thermal stability of the antibacterial environment-friendly packaging thin film are improved.

Description

technical field [0001] The invention relates to the field of packaging films, in particular to an antibacterial and environment-friendly packaging film and a preparation method thereof. Background technique [0002] Food is rich in nutrients, and microorganisms can grow and reproduce in large numbers under suitable temperature and humidity conditions. Good food packaging can guarantee food quality, prevent food from being polluted by microorganisms or other substances in the process of production, transportation, storage, sales, etc., reduce the incidence of food oxidation and other reactions, and extend the shelf life; Appearance and value-added functions. [0003] In recent years, the development and application of new materials and technologies for food packaging has been increasing day by day, and people's requirements for food packaging have also increased. Consumers generally hope to buy food with good taste, safe quality and no preservatives. However, currently com...
