Environmental protection paper structure for foods container and manufacture method thereof

Abstract

The invention relates to an environmental protection paper structure for a food container and a method for producing the environmental protection paper structure, belonging to the living goods. The method comprises the steps as follow: the two sides of the primary reel layer are firstly roll-printed through a roller group to cover the first upper and lower bridging agent coat; the first upper andlower bridging agent coating is then molded through a first drying device; a first biological resoluble film layer coat is firstly covered on the surface of the first upper bridging agent coat through a film lamination machine, and then is integrated through a cooling roller group; a second biological resoluble film layer coat is then covered on the surface of the first lower bridging agent coat through an other group of film lamination machine, and then is integrated through another cooling roller group; finally, a second bridging agent coat and an anti-adhesive coat are covered on the outersurface of the first biological resoluble film layer coat and the second biological resoluble film layer coat through another roller group, and then are dried and molded through a second drying device; and a collecting rack is used for collecting the finished products. The invention has the advantages of continuous operation, short production time, increased yield, reduced cost and anti-adhesive property.

Description

technical field [0001] The invention relates to daily necessities, in particular to an environment-friendly paper material structure for food containers and a manufacturing method thereof. Background technique [0002] As we all know, generally used decomposable cardboard for making food containers is provided with a biodegradable PLA (polylactic acid) film layer coated with a film on the surface of the cardboard of the base paper roll, in order to provide cutting Made into various paper tableware, the biodegradable film layer can be a PET film layer, and the biodegradable film layer can also be a starch layer. [0003] The above-mentioned PLA film layer structure coated on one surface of the cardboard mainly has the characteristics of complying with food-grade container regulations, and can be produced by automatic consistent operations. The only fly in the ointment is that when the structure is initially manufactured, it is directly rolled into a cylindrical shape with a ...
