Paper and plastic composite light packaging film, manufacturing method thereof, and tag bag

Abstract

The invention discloses a paper and plastic composite light packaging film. The paper and plastic composite light packaging film sequentially comprises an outer layer, a middle layer and an inner layer from outside to inside; and the outer layer is a BOPP film with the thickness of 15-20 [mu]m, the middle layer is brown paper with the gram weight of 24-35 g / m<2>, and the inner layer is a PP film with the thickness of 15-25 [mu]m. A manufacturing method of the paper and plastic composite light packaging film comprises the following steps: 1, producing the brown paper and the BOPP film; 2, carrying out hot melt coating on one side of the brown paper with the PP film through an extrusion tape casting technology in order to obtain a middle layer and inner layer composite structure; and 3, bonding the BOPP film with the other side of the brown paper through a composite process in order to obtain the paper and plastic composite light packaging film. The invention also discloses a tag bag. The surface of a bag body made of the paper and plastic composite light packaging film is provided with an unpacking notch, the corresponding position of the bag body is provided with a seal label used for covering the unpacking notch, and the inner side of the seal label is provided with a removable glue layer which can be bonded to the surface of the bag body.

Description

technical field [0001] The invention relates to a paper-plastic composite light packaging film, a manufacturing method thereof and a label bag, belonging to the technical field of flexible packaging. Background technique [0002] The natural functions of packaging include: protection of the contents, convenient use, convenient storage and display, and convenient recycling. In social life, packaging brings convenience to the transportation, sales and use of products, but excessive packaging is also a problem that often arises in the production and business activities of enterprises: too many packaging consumables, too heavy, too large, and too expensive The existence of excessive packaging problems such as high quality and overly ornate decoration, on the one hand, causes a waste of resources, on the other hand, it also makes it difficult to recycle the overused packaging, which is harmful to the environment. [0003] Taking the labeling bag as an example, the labeling bag i...

Problems solved by technology

In social life, packaging brings convenience to the transportation, sales and use of products, but excessive packaging is also a problem that often arises in the production and business activities of enterprises: too many packaging consumables, too heavy, too large, and too expensive Existence of excessive packaging problems such as high quality, ornate decoration, etc., on the one hand, it causes waste of resources;

Aluminized PET, which has high strength and high barrier properties but is difficult to recycle, is used in its packaging materials only to obtain high stiffness characteristics when aluminized PET film is made into bags. This is an overuse of packaging materials.
