Embodiment Construction

[0016] The packaging bag of the present invention and its preparation and application will be further described below by taking the powder bag for external application in the field of medicine as an example.

[0017] The base material of the packaging bag is non-woven fabric. Its specific production is as follows:

[0018] 1. Lay a layer of non-woven fabric horizontally by the traction roller, and place it under the distributing mechanism, and then divide the medicinal powder into many small cylinders by the distributing device according to the designed weight, and arrange them evenly on the non-woven fabric. There are several small cylindrical holes evenly distributed on the feeding device, after feeding, the powder is arranged in a small cylindrical shape.

[0019] 2. Cover another layer of non-woven fabric of the same size on the small cylindrical powder. It can also be achieved by pulling rollers.

[0020] 3. Use an ultrasonic welding device with a power of 1000-5000W t...

Abstract

The invention provides a multi-point evenly distributed powder packaging bag for even distribution of powder. A preparation method thereof is as follows: first, a layer of substrate of the packaging bag is horizontally laid, the powder to be packaged is divided into a plurality of small columns by a feeding device according to designed weight and evenly distributed on the substrate of the packaging bag laid horizontally; and the small column powder is covered by a layer of substrate of the packaging bag with the same size; then the two layers of substrate of the packaging bag are compounded together by ultrasonically pressurizing and welding, and finally the substrate is cut along compounded seams to obtain the multi-point evenly distributed powder packaging bag. The powder inside the powder packaging bag is distributed like small columns, and the weight of the powder inside the bag is easy to control. The bag is mainly applied to the field of medicine.

Description

technical field [0001] The invention belongs to the technical field of packaging, and relates to a powder packaging bag, in particular to a packaging bag in which the powder is evenly distributed, and is mainly used for packaging small and medium-sized powders in the fields of medicine and the like. Background technique [0002] At present, most powders are packaged in packaging bags in an irregular and uncontrollable form, and the powder is unevenly distributed in the bag. In some fields, the powder in the bag needs to be evenly distributed in the bag. For example, in the powder patch in the medical field, the powder in the patch is packed in a packaging bag in an irregular and uncontrollable manner. The uneven distribution of the powder is not conducive to the release of active ingredients and skin absorption. Contents of the invention [0003] The object of the present invention is to provide a multi-point evenly distributed powder packaging bag in which the powder is ...
