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 2

[0022] 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 present invention adds a layer of composite fiber packaging board with waterproof and antirust functions to the inner layer on the basis of the above packaging method ; Its main point is that described guard plate, end guard plate can also adopt the composite fiber packing plate with waterproof, antirust function.

[0023] Please refer to the attached Figure 5 . First, the inner and outer guard plates 12, 11 and end guard plates 13 made of composite fiber packaging boards with waterproof and antirust functions are used to inner-pack the coiled material. The inner guard plate 12 passes through the cavity of the coiled material, and the outer guard plate The plate 11 covers the outer surface of the coiled material, the inner edges of the guard plates 13 at both ends are buckled with the two ends of the inner and...

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 ...
