一次性外卖打包盒组成材料的优点

  外卖打包盒的主要材质有PP(聚丙烯)和PS(聚苯乙烯)等。其中,PP材质的打包盒无毒、无味、无嗅,具有耐高温特性,适合盛装热饭热菜,可在微波炉里加热,甚至可在蒸气柜里蒸煮。

The main materials for takeaway packaging boxes include PP (polypropylene) and PS (polystyrene). Among them, PP material packaging boxes are non-toxic, odorless, and odorless, with high temperature resistance characteristics, suitable for holding hot rice and vegetables. They can be heated in a microwave or even steamed in a steam cabinet.

  PP(聚丙烯)材料是一种广泛应用于制造塑料制品的热塑性树脂。它具有许多优良的特性,如低密度、高韧性、耐磨损性、抗冲击性等。在本文中,我们将讨论PP材料的成分、物理特性以及在高温下可能产生的有害物质失控现象。

PP (polypropylene) material is a thermoplastic resin widely used in the manufacturing of plastic products. It has many excellent characteristics, such as low density, high toughness, wear resistance, impact resistance, etc. In this article, we will discuss the composition, physical properties, and potential loss of control of harmful substances in PP materials at high temperatures.

  首先,PP材料通常由聚丙烯这种聚合物制成。聚丙烯分子的化学式为(C3H6)n,其中n为一个整数,代表聚合物中单体的数量。聚丙烯是一种由烯烃聚合反应制成的热塑性塑料。它通常通过聚合单体丙烯来制成,可以采用不同的方法生产聚丙烯,包括均相聚合、异相聚合和无障碍聚合。不同的生产方法会产生不同的聚合度、分子量分布和分子结构,这些因素在PP材料的物理特性方面具有很大的影响。

Firstly, PP materials are typically made from polymers such as polypropylene. The chemical formula of polypropylene molecule is (C3H6) n, where n is an integer representing the number of monomers in the polymer. Polypropylene is a thermoplastic made by the polymerization reaction of olefins. It is usually made by polymerizing monomer propylene and can be produced using different methods, including homogeneous polymerization, heterogeneous polymerization, and barrier free polymerization. Different production methods can result in different degrees of polymerization, molecular weight distribution, and molecular structure, which have a significant impact on the physical properties of PP materials.

  其次,PP材料也有几个显著的物理特性。PP材料具有优异的水密性和化学惰性,可以轻松抵御腐蚀和药品侵蚀。此外,PP材料也具有良好的耐热性能,可以耐受高温高压的环境。它还具有较好的透明性和化学惰性,使得它在食品包装、药品瓶、医疗器械等领域有着广泛的应用。

Secondly, PP materials also have several significant physical properties. PP material has excellent water tightness and chemical inertness, which can easily resist corrosion and drug erosion. In addition, PP materials also have good heat resistance and can withstand high temperature and high pressure environments. It also has good transparency and chemical inertness, making it widely used in food packaging, drug bottles, medical devices and other fields.
