Embodiment 1

[0020] According to customer requirements, use high-speed printing machine to print corresponding patterns and characters on the outer surface of PP film. Mix the quality of Sinopec polyethylene 1C7A and imported polyethylene 107A to obtain the coating material, use the laminating machine to heat and melt the coating material, and then bond the inner surface (unprinted surface) of the PP film to the non-woven fabric (note the vertical and horizontal Staggered bonding) to obtain semi-finished coils. Prepare the handle made of non-woven fabric, and use the fully automatic high-speed integrated bag making machine to assemble the semi-finished roll material and the handle into a handbag.

[0021] After analyzing the amount of raw materials and dismantling a single handbag, it is found that the whole handbag is nearly 100g, of which the PP film part weighs about 15g, the non-woven fabric part weighs about 70g, and the coating material weighs about 15g.

Embodiment 2

[0023] According to customer requirements, use high-speed printing machine to print corresponding patterns and characters on the outer surface (PP layer) of PP / PT composite film. Using the same coating material as in Example 1, under the action of the coating machine, the inner surface (cellophane layer) of the PP / PT composite film is bonded to the non-woven fabric (note the criss-cross bonding) to obtain a multi-layer composite roll Then according to the customer's requirements, bronzing treatment is carried out on the specific area of ​​the outer surface (PP layer) of the multi-layer composite roll material; finally, a handle made of non-woven fabric is prepared, and the multi-layer composite roll material is made of a fully automatic high-speed integrated bag making machine. Assemble with the handle to form a tote bag.

[0024] Analysis and testing found that the entire handbag weighs over 100g, of which the PP / PT composite film part weighs about 20g, the non-woven part wei...

Embodiment 3

[0026] According to the customer's requirements, use a high-speed printing machine to print corresponding patterns and characters on the outer surface (PP layer) of the PP / pearl luster composite film. Using the same coating material as in Example 1, kraft paper and non-woven fabric are first bonded under the action of the coating machine to obtain a semi-finished roll material; Layer) and the kraft paper surface of the semi-finished coil material are bonded together to obtain a multi-layer composite coil material. During this period, care should be taken to ensure that the layers are criss-crossed and bonded; Bronzing treatment; finally prepare the handle made of non-woven fabric, and use the fully automatic high-speed integrated bag making machine to assemble the multi-layer composite roll material and the handle into a handbag.

[0027] Analysis and testing found that the entire handbag weighs over 140g, of which the PP / pearl composite film part weighs about 20g, the kraft p...

Abstract

The invention relates to a multi-layer composite hand bag good in surface tactility and resistant to bending and a preparation method thereof. The multi-layer composite hand bag comprises an outer composite film layer and an inner non-woven fabric layer, a brown paper layer can be added between the outer composite film layer and the inner non-woven fabric layer, and the layers are crisscross and tightly composited through polyethylene film laminating material. The multi-layer composite hand bag has the particular advantages that a new film layer structure is adopted, the multi-layer composite hand bag is enable to be good in tactility and attractive in appearance, and by the aid of the middle brown paper layer and the unique compositing manner, the multi-layer composite hand bag is enabled to be high in strength, toughness and deflection and have no obvious bending marks after being bended for several times.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a multi-layer composite handbag with good surface touch and bending resistance and a preparation method thereof. Background technique [0002] In daily life, whether it is buying clothes, shoes or mobile phones, the purchased goods are usually packed into handbags and then handed over to customers. It can be seen that handbags have brought great convenience to our lives. In addition to having a certain strength and being able to bear a certain weight, these shopping handbags must also have good water resistance and tear resistance. In addition, the feel and appearance of the handbag are also very important, which affects the sales of goods to a certain extent. [0003] Common handbags currently on the market include paper bags, plastic bags, cloth bags (such as non-woven fabrics), paper-plastic or cloth-plastic composite bags. Although paper bags are environmentally...
