What are the materials for scraping cards? What are the substrates?
The material of the scraping card can be different from the type of manufacturer, region and lottery, but the following materials are usually used:
First, the surface: The surface is the outermost layer of the scratch card. It needs to cover a layer of opaque coating to achieve the effect of hiding numbers or symbols after scraping. This coating is usually metal foil, plastic or epoxy resin.
Second, substrate: The substrate is the bottom layer of the support surface layer. It is usually made of paper or plastic materials. Paper substrates are more common, but plastic substrates are more waterproof and durable.
1. Paper substrate: This is the most common type of substrate. Usually, high -quality paper is used, such as bronze paper, pearl paper or cotton paper. The paper substrate is cheaper, but it is not durable and waterproof.
2. Plastic substrate: Plastic substrates can choose polyester film, polyethylene film or PVC material. Compared with paper substrates, plastic substrates are more waterproof, durable and difficult to tear, but the cost is also high.
When producing scraping cards, the manufacturer will choose the substrate type according to actual needs. For example, if you need to produce better anti -counterfeit scraping cards, you can use plastic substrates. If you need to save costs, you can use paper substrates. At the same time, for some special use scraping cards, other types of substrates, such as metal or composite materials.
