Environment-friendly anti-condensation water-absorbing packaging bag

Abstract

The invention provides an environment-friendly anti-condensation water-absorbing packaging bag which comprises a bag body made of a woven fabric. A thin film is sprayed on the surface of the bag body,a layer of non-woven fabric is arranged in the bag body, the non-woven fabric and the bag body are connected through threads or adhesive tape which is easy to disassemble and separate, the lower faceof the bag body can be open, an interlayer between the non-woven fabric and the bag body is filled with water-absorbing substances and an antirust agent. The bag has the advantages that the bag can absorb moisture in the bag, condensation water drops are prevented from being generated on the surface of a metal part, and rusting is prevented; the non-woven fabric and the woven fabric are linearlyconnected, so that the non-woven fabric and the woven fabric are conveniently separated, classified recycling is facilitated, and higher environmental friendliness is achieved; and the woven fabric isused as the bag body, so that the bag is higher in strength, not prone to damage, firm and durable; The packaging bag is suitable for moisture-proof anti-condensation packaging of various metal objects, and is particularly suitable for packaging protection of metal objects such as steel coils, train wheel hubs, ring pieces, mechanical equipment or parts.

Description

technical field [0001] The invention relates to a packaging material, in particular to a packaging bag for large items containing metal. Background technique [0002] There are many large metal objects, such as steel coils, train wheel hubs, mechanical equipment, etc., that need to be packaged to prevent dust, wind, and rain. Currently, the commonly used packaging method for large items is to cover them with plastic film, or Wrapped up, because it is inconvenient to lift large objects, the bottom generally cannot be completely wrapped up. The current packaging method can be dustproof and waterproof, but its disadvantage is that there will be water vapor inside the article, and the water vapor will condense, and a lot of water droplets will be produced on the surface of the article, causing the metal article to rust. [0003] For the packaging of metal objects, another packaging method is to use anti-rust paper packaging. The anti-rust paper is coated with anti-rust agent on...

[0002] There are many large metal objects, such as steel coils, train wheel hubs, mechanical equipment, etc., that need to be packaged to prevent dust, wind and rain. Currently, the commonly used packaging method for large items is to cover them with plastic film, or Wrap it up, because it is inconvenient to lift large objects, so the bottom cannot be completely wrapped up

The current packaging method can be dustproof and waterproof, but its disadvantage is that there will be water vapor inside the article, and the water vapor will condense, and a lot of water droplets will be produced on the surface of the article, which will cause the metal article to rust

[0003] For the packaging of metal objects, another packaging method is to use anti-rust paper packaging. The anti-rust paper is coated with anti-rust agent on the anti-rust base paper, which can play the role of anti-rust. In order to increase the strength, the general anti-rust paper is covered with The film is covered with a layer of woven cloth, which is not easy to break, but this kind of anti-rust paper is not environmentally friendly, and the cost is high, because the paper and plastic are combined together, it is difficult to separate, the anti-rust paper after use can neither be treated as waste paper, It cannot be treated as waste plastic products. It is generally disposed of by incineration or landfill, which pollutes the environment and brings great trouble to users.
