The materials of packaging paper tray products are divided into many types, such as bamboo pulp, wood pulp, corrugated pulp, large white pulp (also known as white pulp or A4 pulp), sugarcane pulp, etc., among the many materials used in packaging paper tray products. Most of them are white pulp and sugarcane pulp. How to distinguish between the two?
In fact, it is very simple. First of all, from the perspective of color, although they are all white, the paper tray of sugarcane pulp will look a little yellower, and the white pulp will be as bright as the A4 copy paper we usually use in office.
Secondly, looking at the toughness of the product, the general wet pressing process rarely uses white pulp. Therefore, from the perspective of dry pressed paper support, sugarcane pulp is soft because of its soft fiber and the dry pressed product itself is not particularly compact, which makes The hardness of dry-pressed sugarcane pulp packaging paper trays will not be as good as that of white pulp.
Generally, the products selected for dry pressing process are considered from the protection of the product. Therefore, it is recommended that you choose white pulp paper trays when making dry pressed paper trays.
