preparation example Construction

[0026] A preparation process for a self-supporting compression bag, comprising the steps of:

[0027] Step 1: Put the raw material of the bag body in the reaction kettle to melt at high temperature, and put the melted raw material into the film blowing machine to blow out the material film;

[0028] Step 2: Place the raw material of the bag holder in a reactor for high-temperature melting, pour the melted raw material into a twin-screw extruder, and extrude it to prepare the bag holder;

[0029] Step 3: Seal and press the bag seat and the bag body to obtain a self-supporting compressed bag.

[0030] The film blowing temperature of the film blowing machine is 130°C.

Embodiment 1

[0032] A self-supporting compression bag, comprising a bag body and a bag seat, the bag body is measured in parts by weight, including: the bag body is measured in parts by weight, including: 46 parts of ethylene, 13 parts of polytetrafluoroethylene, 14 parts of kaolin, and cryolite 9 parts, 4 parts of lubricant, 2 parts of stabilizer and 2 parts of plasticizer; the bag seat is calculated by weight, including: 16 parts of polyether polyurethane, 7 parts of tree ash, 12 parts of ethylene propylene rubber, high carbon chromium 7 parts of iron powder, 3 parts of nano titanium dioxide, 4 parts of polyethylene wax micropowder, 7 parts of titanium dioxide, 4 parts of tributyl phosphate, 5 parts of polyacrylamide and 11 parts of compatibilizer.

Abstract

The invention discloses a self-standing compression bag and a preparation process, and belongs to the technical field of packaging bags, the self-standing compression bag comprises a bag body and a bag seat, the bag body comprises, by weight, 40-60 parts of ethylene, 10-20 parts of polytetrafluoroethylene, 10-20 parts of kaolin, 5-10 parts of cryolite, 3-5 parts of a lubricant, 1-3 parts of a stabilizer, and 1-3 parts of a plasticizer; and the bag seat is prepared from, by weight, 13-20 parts of polyether polyurethane, 4-9 parts of tree ash, 8-14 parts of ethylene propylene rubber, 2-9 parts of high-carbon ferrochrome powder, 1-4 parts of nano titanium dioxide, 1-5 parts of polyethylene wax micro powder, 5-10 parts of titanium dioxide, 1-5 parts of tributyl phosphate, 4-9 parts of polyacrylamide and 7-12 parts of a compatilizer. The compression bag is sealed and pressed together in the mode that the bag body and the bag seat are combined, the compression bag can stand by itself, and the defect that a traditional compression bag cannot stand by itself is overcome.

Description

technical field [0001] The invention relates to a compression bag and a preparation process, in particular to a self-supporting compression bag and a preparation process, belonging to the technical field of packaging bags. Background technique [0002] Self-supporting compression bag refers to a flexible packaging compression bag with a horizontal support structure at the bottom, which does not rely on any support and can stand on its own regardless of whether the bag is opened or not. [0003] The existing compression bags have the following deficiencies in the process of use: the traditional compression bags have a single bag type, and the storage capacity of the contents is also very limited; at the same time, the compression bags are easily broken when they are stored for a second time after being stored for one year. Contents of the invention [0004] The main purpose of the present invention is to provide a self-supporting compression bag and a preparation process in...
