Embodiment Construction
[0010] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0011] like figure 1 Shown, a kind of multi-layer fresh-keeping paper, described multi-layer fresh-keeping paper comprises fresh-keeping paper 2 and BOPP film 3, and described fresh-keeping paper 2 is provided with nano-film 1, can effectively block the preservative in the fresh-keeping paper 2 from penetrating into food In order to avoid harm to the human body, it is safe and non-polluting. The BOPP film 3 is bonded to the fresh-keeping paper 2 and has high tensile strength, impact strength, rigidity, and toughness. The plastic wrap is not easily damaged, thus keeping items fresh for a long time.
[0012] It should be noted that the thickness of the fresh-keeping paper 2 is 60-80 μm, which is convenient for processing.
