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.

Abstract

The invention discloses multilayer plastic wrap and relates to the field of packing materials. The multilayer plastic wrap comprises plastic wrap and a BOPP (Biaxially-oriented Polypropylene) thin film, the plastic wrap is provided with a nano-film, the BOPP thin film is adhered to the plastic wrap. The multilayer plastic wrap can effectively prevent preservatives in the plastic warp from permeating into food to avoid damage to human bodies, thereby being safe and pollution-free; is provided with performances of high tensile strength, high impact strength, high rigidity and high obdurability, thereby being not easy to damage during a goods transportation and movement process, and guaranteeing lasting freshness of goods.

Description

technical field [0001] The invention is applicable to the field of packaging materials, and in particular relates to a multi-layer fresh-keeping paper. Background technique [0002] Preservative paper and preservative film are things that people often use in daily life. Its main function is to keep items fresh and not easily corroded. With the development of society and the improvement of people's living standards, the requirements for fresh-keeping materials are also increasing. will get higher and higher. The application number is CN98244581.4, which discloses a composite fresh-keeping paper for fruits and vegetables. The preservative is clamped between the substrate sheet and the covering material sheet, and the two sheets are bonded together by an adhesive. Good effect and low cost, but the preservative between the layers of the fruit and vegetable composite fresh-keeping paper is easy to penetrate into the fruits and vegetables, causing harm to the human body, and the ...
