Problems solved by technology

Packaging steel coils with the above packaging materials has the following disadvantages: the vapor phase antirust packaging film is a paper-plastic composite product, which has poor antirust performance. Generally, the water permeability of the composite antirust paper is lower than 25g / m. 2 .24h, and this kind of material is not conducive to recycling and pollutes the environment; due to the poor cushioning performance of the steel end corner protector, the steel guard plate is easy to cause damage to the paper-plastic composite vapor phase antirust paper when it hits, resulting in the loss of the antirust paper. It is easy to cause damage to the end and surface of the steel plate; ordinary fiberboard is easy to absorb water and get damp, and the sealing is not good, which is easy to cause steel corrosion

Embodiment 1

[0019] See attached figure 1 , 2 , the present invention includes industrial composite packaging film, guard plate, end guard plate and metal corner protector, using the above-mentioned materials as packaging materials, industrial packaging film 3 is a three-layer composite film formed by co-extruding a waterproof layer, a reinforcing layer and an antirust layer Packaging film, this industrial composite film 3 is co-extruded from three layers of plastics of different materials, one of which contains gas phase corrosion inhibitor and other additives, the reinforcing layer contains reinforcing agent, and the waterproof layer contains waterproofing agent, which has good Waterproof, antirust, and has high strength. In addition, a degradable masterbatch is added to the packaging film, so it is beneficial to environmental protection. After testing, at normal temperature, the tensile strength of the three-layer composite packaging film used in the present invention is greater than ...

Embodiment 2

[0025] In order to improve the quality of steel packaging, meet the requirements of steel export transportation, and better meet the needs of ocean transportation, the above-mentioned guard boards and end guard boards are made of composite fiber packaging boards with waterproof performance and waterproof, rust-proof performance composite fiber packaging board, this composite fiber packaging board with waterproof and antirust performance is coated with a vapor phase antirust layer 14 on the inner side of the composite fiber packaging board with waterproof performance, such as Figure 7 shown.

[0026] The packing method that adopts above-mentioned packing material comprises the following steps (see attached Figure 5 ):

[0027] 1) The inner guard plate 12, outer guard plate 11 and end guard plate 13 made of composite fiber packaging board with waterproof and anti-rust performance are used to inner-pack the coiled material, and the inner guard plate 12 passes through the cavit...

Abstract

The present invention relates to a packaging material for coiled material and its packaging method. It uses industrial composite packaging film, protection plate, end protection plate and metal protective corner as packaging material, and is characterized by that the industrial packaging film is formed from three layers of water-proofing layer, reinforcing layer and rust-proofing layer through the process of co-extrusion, its protection plate and end protection plate adopt the composite fibre packaging plate with water-proofing property. Said invention also provides the use method of these packaging material, and its packaging effect is good and solves the problem of resisting rust for coiled material.

Description

technical field [0001] The invention relates to the field of metal packaging, in particular to a packaging material for coil packaging and a packaging method. Background technique [0002] At present, steel materials such as plates and coils are packaged with paper-plastic composite vapor-phase antirust packaging film, and the outer layer is covered with an iron sheet retainer. The packaging board generally adopts steel guard board or ordinary fiber board. Packaging steel coils with the above packaging materials has the following disadvantages: the vapor phase antirust packaging film is a paper-plastic composite product, which has poor antirust performance. Generally, the water permeability of the composite antirust paper is lower than 25g / m. 2 .24h, and this kind of material is not conducive to recycling and pollutes the environment; due to the poor cushioning performance of the steel end corner protector, the steel guard plate is easy to cause damage to the paper-plastic ...
