Embodiment Construction

[0010] The embodiments will be further described in detail below in conjunction with the accompanying drawings.

[0011] refer to figure 1 , 1-paper, 2-degradable coating, 3-aluminum foil, 4-degradable coating, 5-degradable polyethylene (PE) film. The present invention is a profile used for making packaging bags or boxes for packaging food and other materials, which is specifically cut according to the unfolded shape of the packaging bag or box, and then shaped. The structure of the profile is analyzed from the cross-section, and there are five layers in total. The first layer is paper (1), and the thickness of paper (1) is 0.05-0.5mm. Generally, kraft paper is used, such as 50 grams of paper; the second layer is a degradable coating layer. (2), its thickness is 0.015-0.04mm; the third layer is aluminum foil (3), its thickness adopts 0.006-0.02mm; the fourth layer is degradable coating material layer (4), its thickness is the same as the second layer ; The fifth layer of deg...

Abstract

The invention relates to material packaging section bar, especially relates to fully decomposed high sealed compound packaging section bar for producing package bag or box. The feature is: the section bar has fiver layers: the first layer is paper, the second layer is decomposed painting layer, and the third layer is aluminum foil, the fourth layer is decomposed coating material layer, the third layer is decomposable ethane film layer. The decomposed coating layer is pasted to the first layer and the third layer; the decomposed coating is connected to another surface of the third layer and the fifth layer. The product reduces the white contamination, and it protects the environment effectively.

Description

technical field [0001] The invention relates to material packaging profiles, in particular to paper-plastic fully degradable high-sealing composite packaging profiles for making packaging bags or boxes. Background technique [0002] The paper bag or carton packaging popular in the market in our country is made of paper and polyethylene coated, because the sealing performance of polyethylene is not ideal, and the air tightness can only reach 97%, resulting in the intrusion of air in the packaging bag, thus making the packaging The items in the bag, especially the shortened shelf life of food, are prone to mold and deterioration. When making this kind of packaging bag or box, the composite paper-plastic profile is used in advance, then cut into the expanded shape of the packaging bag or box on a special mold, and finally formed on a special equipment. Since the polyethylene in this profile is a plastic film and does not have degradability, a large number of packaging bags or ...
