Problems solved by technology
[0002] With the rapid development of the economy, people's requirements for packaging materials are getting higher and higher, especially high-performance packaging materials for medical equipment and industry are mostly dependent on imports, which have the disadvantages of high cost and long purchase cycle. Woven cloth / paper instead, both of these two materials have fatal disadvantages: paper is easy to break, not waterproof, poor heat sealability, non-woven fabric has poor printing effect, heavy weight, and the firmness does not meet the requirements

Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention will be further described
[0022] The first step is to put the first raw material roll, and place the first raw material roll on the first raw material roll 1. According to the production requirements and glue performance, the first raw material roll is polyester non-woven fabric or polyethylene breathable film. The above materials Door width: 920mm, quantitative 70g / m 2 , the tension of the first unwinding is controlled at 5kg;
[0023] In the second step, the coating roller is pressed down and glued, and the material on the first raw material roll is introduced between the gravure top rubber roller 3 and the glue pressure roller 4 for gluing, and a glue pool is provided below the gravure top rubber roller 3 2. There is a glue scraper 5 on one side, and the pressure of the gluing roller is controlled at 5kg;
[0024] Select polyurethane adhesive: the model is Mitsui Takeda 969V;
[0025] The work...

Abstract
The invention relates to a composite membrane packaging material and the manufacture process thereof, which is applicable to medical instruments and industry. In the invention, polyester non-woven fabric and polyethylene breathable capsule are adopted to be put on a first material roll, and the obtained substance is pressed to be coated with adhesive by a coating roller, heated to be dried by a braking tunnel; then, the obtained substance is put on a second material roll, pressed to be composite by a composite roller and then the material is completed by roll regaining and curing process. Thenovel packaging material manufactured by adopting the material and the technical process has strong and durable material, higher strength than paper, low price, wider application than non-woven fabric; the invention combines all the advantages of paper, membrane and the non-woven fabric.
Description
technical field [0001] The invention relates to a manufacturing method of a packaging material, more specifically to a manufacturing method of a composite film packaging material used in medical equipment and industry. Background technique [0002] With the rapid development of the economy, people's requirements for packaging materials are getting higher and higher, especially high-performance packaging materials for medical equipment and industry are mostly dependent on imports, which have the disadvantages of high cost and long purchase cycle. Both of these materials have fatal disadvantages: paper is easy to break, not waterproof, and has poor heat sealing performance; non-woven fabric has poor printing effect, heavy weight, and unsatisfactory firmness. Contents of the invention [0003] The purpose of this invention is to combine the advantages of paper and non-woven fabrics to meet the needs of new packaging materials: high strength, waterproof, light weight, soft, sm...
