Problems solved by technology

After a comprehensive study of this comparative document and related prior art, it is found that the following problems still exist in the structure, formula composition, and preparation method of the vacuum compression bag: (1) The antibacterial performance of the compression bag material is improved by adding an antibacterial agent of organic compounds , in theory, antibacterial and antifungal effects can be achieved for conventional home environments, but it is difficult to guarantee good antibacterial and antifungal effects in environments with high temperature and volatile gases; (2) When applying vacuum compression bags to high temperature and corrosive environments , the volatile corrosive gas penetrates from the outer layer to the inner layer, the outer layer structure is susceptible to heat embrittlement, the impact resistance of the middle layer structure decreases, the inner layer structure is difficult to resist corrosive gas, and the protection effect on the items in the bag is reduced; (3) most of them use Single-layer structure, after extrusion casting into film, the overall performance of the obtained product is not good, it is necessary to study the multi-layer composite film to achieve high temperature resistance, impact resistance, antibacterial compression vacuum bag with excellent performance

Abstract

The invention discloses a vacuum compression bag with an antibacterial function and a production process thereof, and relates to the field of packaging materials. The vacuum compression bag is formed by a high-temperature-resistant outer layer, a first antibacterial adhesive layer, an impact-resistant intermediate layer, a second antibacterial adhesive layer and a corrosion-resistant inner layer from outside to inside through hot pressing. The production process comprises the seven procedures of preparation of the high-temperature-resistant outer layer, preparation of the impact-resistant intermediate layer, preparation of the corrosion-resistant inner layer, preparation of an antibacterial adhesive, coating, hot-pressing and rewinding and hot melting. Compared with the prior art, the vacuum compression bag has excellent antibacterial property, corrosion resistance, impact resistance, breakdown resistance and high temperature resistance, and is suitable for vacuum storage of materials in a high-temperature corrosion environment, the impact strength reaches 36 MPa, the tensile strength reaches 52.4 MPa, the elongation at break reaches 106%, and the antibacterial rate to escherichia coli, staphylococcus aureus and candida albicans reaches 99.7%, 98.3% and 95.7% correspondingly.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a vacuum compression bag with an antibacterial function and a production process thereof. Background technique [0002] Compression bags can prevent fleas, mold, moisture, bad odor, etc., and keep clothes clean and preserved. It can be divided into vacuum compression bags, suction quilt compression bags, hand-rolled vacuum compression bags, sitting pressure vacuum compression bags, etc. The working principle of the vacuum compression bag is to take out the air inside the compression bag to reduce the volume, and use the atmospheric pressure to flatten the originally inflated inner contents and other items to isolate the outside air. The compression bag can easily save 75% of the space and effectively expand the storage space. [0003] The vacuum compression bags sold on the market mainly have two materials, one is polyamide plus polyethylene, the vacuum compression ...
