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 ...
