The idea of harmonious coexistence between man and nature has gained significant prominence. General Secretary Xi Jinping places great importance on ecological and environmental protection, offering clear directives for ecological preservation efforts within the delivery industry [1]. He emphasizes the necessity to address packaging waste in online shopping and express delivery, eliminate excessive packaging, and reduce environmental waste and pollution. In this process, China Post will actively respond to the central government’s imperatives and formulate a series of strategies and plans, including green post ideas, transportation, packaging, and finance.展开更多

In this study,the LCA method was used to evaluate the environmental impact of Baosteel’s newly developed process for manufacturing film-laminated steel packaging materials,from raw material mining,production,and processing to their storage,consumption,recycling,and final disposal. The environmental performance and main influencing factors were analyzed and compared. In addition,the life cycle environmental characteristics of film-laminated steel cans,tin-plated steel cans,and aluminum cans were compared. Of the main environmental indicators of the life cycle of the film-laminated steel can,the environmental load of the substrate accounts for the largest proportion,follow ed by electricity. The environmental impact of the production of film materials cannot be ignored. The overall environmental performance of film-laminated steel cans is better than that of aluminum cans.展开更多

For this purpose, first, the Alyssum homolocarpum seed gum (AHSG) film was enriched with various levels (1–20% w/w) of Echinacea purpurea (L.) extract-phospholipid phytosome (EEPP) and, then, the structural (FTIR and SEM), thermal, physicochemical, mechanical and radical scavenging properties of the films as well as release kinetics of the extracts from the films were evaluated. Then, the chicken meat was packaged with the developed film and its different parameters including microbial population, chemical indices (TBARS and pH) as well as sensory properties of the meat were compared with those of the control film. Based on the results, as the EEPP percentage increased, water solubility, moisture content, water vapor permeability of AHSG films decreased favorably, and their tensile strength enhanced successfully. Besides, incorporation of EEPP improved the radical scavenging properties and melting point of the base film considerably. Structural surveys revealed that some chemical interactions (hydrogen bonds) occurred between EEPP and AHSG matrix. A two-fold increase in the shelf life of meat was recognized as the microbial and chemical indices of the developed film after 14 days were even better than those indices of the control film after 7 days.展开更多
