EVA linings did not need to be processed by engraving at first. As a shockproof material for product transportation protection, EVA has excellent shock resistance. At the same time, EVA is easy to process and can be easily cut with ordinary knives, which means that people can directly buy EVA sheets and then cut them into the required size with knives according to the packaging needs.

Although this simple method can also provide sufficient protection, for some special-purpose products or for some products that require packaging appearance, direct cutting obviously cannot meet people’s needs. For linings of the same shape and with particularly large demand, manual cutting is too primitive, so die-cutting has its place. It can quickly mass-produce EVA linings of the same specification, so it can meet the protective packaging needs of a large number of products in a single packaging form.

However, the die-cutting method also has its shortcomings, that is, it is difficult to meet the processing of packaging linings of different external dimensions on the same lining, especially for products with multiple thickness and depth requirements. On the other hand, die-cutting cannot achieve the one-piece molding processing of EVA inner support. For some products with particularly high precision requirements, engraving is almost the only choice. Although EVA foam cannot achieve the same processing accuracy as metal, for packaging, only engraving can achieve an accuracy of 1mm or even less.

Back to the title, in which industries can EVA engraved linings be used? The answer is actually self-evident. It is applicable to all industries that have requirements for product packaging. Including but not limited to consumer electronics, medical supplies, battery cells, cosmetics, gifts, and wine…
