Development of novel pizza delivery bags

食品和比萨饼递送公司面临的主要困难之一是在从厨房到顾客的递送阶段期间保持热的烹饪食品（特别是比萨饼）的温度。特别是在寒冷的气候条件下，周围环境和热食物之间的温差可能变得很大。这会导致食品的显著冷却和冷凝，从而影响其质量和味道。尽管保持食物足够温暖似乎很容易，但在将其质量、味道和新鲜度保持在可被视为内部品质的期望水平方面存在与食物相关的挑战，例如温度和水分含量/冷凝水平。还有一些外部品质（或参数/目标）需要实现，例如更好的效率、更好的成本效益、更好的健康、更好的资源利用和更好的环境。此外，同样重要的是，使这些袋子更健康，具有无毒、不易燃、无腐蚀性、不粘、不扩散等材料及其配置。在这方面，迫切需要进行全面的研究，以优化包装袋的储存条件，使其在交付阶段得到高效和有效的使用。因此，该项目旨在开发具有各种选项和配置的新型比萨饼递送袋，以实现比萨饼的最佳（期望）条件。

One of the main difficulties faced by food and pizza delivery companies is to maintain the temperature of hot cooked foodstuffs, particularly pizzas, during delivery stage from the kitchen to the customer. Especially, in cold climatic conditions, the temperature difference between the ambient and hot food may become substantial. This results in significant cooling and condensation of the food which affects their quality and taste. Although it seems to be easy to keep the food warm enough, there are challenges related to the foodstuff, such as temperature and moisture content/condensation level, in keeping their quality, taste and freshness at the desired level which can be seen as internal qualities. There are also external qualities (or parameters/targets) to achieve such as better efficiency, better cost effectiveness, better health, better resources use and better environment. Furthermore, it is equally important to make these bags healthier with non-toxic, non-flammable, non-corrosive, non-sticky, non-diffusive, etc. materials and their configurations. In this regard, there is a strong need to perform comprehensive research to optimize the storage conditions for the bags to be efficiently and effectively used during the delivery stage. Thus, this project aims to develop novel pizza delivery bags with various options and configurations to achieve the optimum (desired) conditions for pizzas.
