Embodiment 1

[0035] This embodiment relates to a composite bag made of non-woven fabric material, which includes a surface printing layer 1 , a reinforcement layer 2 , a barrier layer 3 and an inner film layer 4 arranged in sequence.

[0036] Wherein, the surface printing layer 1 is a PET layer, the reinforcement layer 2 is a non-woven fabric, the barrier layer 3 is an aluminum foil layer, and the inner film layer 4 is a PE layer.

[0037] In this embodiment, the surface printing layer 1, the reinforcing layer 2, the barrier layer 3 and the inner film layer 4 are all bonded together, so the surface printing layer 1, the reinforcing layer 2, the barrier layer 3 and the An adhesive layer is also formed between the inner film layers 4 , and the adhesive layer is a polyurethane adhesive layer 5 .

[0038] In order to enhance the performance of the composite bag, the PE layer is prepared by blending polyethylene materials. According to the total mass of polyethylene materials, it specifically i...

Embodiment 2

[0049] This embodiment relates to a composite bag of non-woven fabric material, and the composite bag is prepared according to the following steps:

[0050] S1. Composite PET / non-woven fabric layer: place the PET film and non-woven fabric film on a dry compound machine for compounding, and the glue amount of the polyurethane adhesive is 3.0g / m 2 , the composite speed is 200m / min, the drying temperature of the first drying tunnel is 10°C, the drying temperature of the second drying tunnel is 20°C, the drying temperature of the third drying tunnel is 25°C, and the temperature of the hot drum is 30°C.

[0051] S2. Composite PET layer / non-woven fabric layer / aluminum foil layer: Place the composite PET / non-woven fabric layer and aluminum foil obtained in S1 on a dry laminating machine for compounding, and the glue amount of polyurethane adhesive is 3.0g / m 2 , the composite speed is 180m / min, the drying temperature of the first drying tunnel is 10°C, the drying temperature of the se...

Embodiment 3

[0054] This embodiment relates to a composite bag of non-woven fabric material, and the composite bag is prepared according to the following steps:

[0055] S1. Composite PET / non-woven fabric layer: place the PET film and non-woven fabric film on a dry compound machine for compounding, and the glue amount of the polyurethane adhesive is 4.0g / m 2 , the composite speed is 200m / min, the drying temperature of the first drying tunnel is 25°C, the drying temperature of the second drying tunnel is 25°C, the drying temperature of the third drying tunnel is 25°C, and the hot drum temperature is 30°C.

[0056] S2. Composite PET layer / non-woven fabric layer / aluminum foil layer: Place the composite PET / non-woven fabric layer and aluminum foil obtained in S1 on a dry laminating machine for compounding, and the glue amount of polyurethane adhesive is 4.0g / m 2 , the composite speed is 200m / min, the drying temperature of the first drying tunnel is 25°C, the drying temperature of the second dr...

Abstract

The invention relates to the field of packaging materials, and in particular relates to a composite bag made of a non-woven fabric material, the composite bag comprises a surface printing layer, a reinforcing layer, a barrier layer and an inner film layer which are sequentially arranged, wherein the reinforcing layer is the non-woven fabric; the reinforcing layer is made of the non-woven fabric, the reinforcing layer is arranged in the composite bag; the non-woven fabric has the advantages of moisture resistance, ventilation, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity, no irritation, rich colors, low price and recyclability; and the non-woven fabric has better tear resistance, so that the tear resistance of the composite bag can be improved.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a composite bag made of non-woven fabric materials. Background technique [0002] Mask packaging bag, as the name suggests, is a packaging bag used to hold and store facial masks. Generally, the film composite structure used in mask bags is usually PET / AL / PE, PET / AL / PET / PE, or matte BOPP / paper / AL / PE and other structures. Due to the low tear strength of such facial mask packaging bags, it is easy to cause leakage. Contents of the invention [0003] Therefore, the technical problem to be solved in the present invention is to overcome the low tear strength of the facial mask packaging bag in the prior art and easily cause the defect of leaking bag, and provide a kind of composite bag of non-woven fabric material. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A composite bag ma...
